[2016_11_23_Wilma_guacamole_rdc] 
Here's a batch of Wilma guacamole I made for our Thanksgiving house guests, roughly following this recipe: http://www.foodnetwork.com/recipes/alton-brown/guacamole-recipe.html. It disappeared in a hurry! I also learned that on older fruit, where the skin has dried out and gotten somewhat wrinkly and tough, it was much easier to peel away from the flesh--which is why this batch doesn't show as many black bits as in the earlier shot.

As is often the case with trying to get plants to grow in challenging climates, there are lots of exceptions, but it's a good idea to protect young avocados from extremes of sun, heat, and cold. I put a shade cloth over mine the first year when it started getting hot, and I covered them with a sheet during freezes during their first winter. It's better to err on the side of caution. Different varieties may need customized treatment--the in-ground Wilma wasn't fazed by hot weather this summer, but a 2-gallon plant grafted from the same tree really suffered, and had to be moved under the eaves. Leaves on the small Opal next to the big Wilma start shriveling when it gets really hot, so it needs temporary shade--but I'm hoping that will change as it gets bigger.

Good luck, Mark--and if you need to try again, let me know.

Here's a paper http://aggie-horticulture.tamu.edu/fruit-nut/files/2015/04/avocados_2015.pdf from Texas A&M that might be useful to anyone growing avocados in marginal areas.

This one http://30r8p93i26e4rjv9qo3ulokei.wpengine.netdna-cdn.com/wp-content/uploads/2013/09/Avocados-For-SA1.pdf gives more information on planting so the union will eventually be below soil level.

Sas, I water them quite a bit, and at this point I'm sure they could get by on less. They're on a drip cycle that comes on every day, and in addition, I've run one of the down-spouts from the roof's rain gutter into the surrounding berm, so they get heavily watered whenever it rains. However, the soil in this part of my yard is sandy and drains rapidly. They are also mulched with several inches of leaves and wood chips.

Mark (starch)--I'm glad to hear it survived the Phoenix inferno! As mild as your winters are, it should push new growth almost continually and become well established by the time the heat returns. I'll be very interested to hear how it does next summer with roots in the ground. It would probably be wise to shade it during the next hot season. Pardon my poor memory, but did you get it as an already-grafted plant, or a scion that you grafted yourself? What rootstock is it on?

I had been confused about reports that Brazos Belle is a genetic clone of Wilma, so I phoned Bill Schneider (who holds the trademark on 'Wilma') about ten days ago to see what he could tell me. He had no information about Brazos Belle, and could not tell me anything about its origins or relationship, if any, to Wilma. However, I learned that Schneider's trademark protects the specific product that he sells, and that he is the only one authorized to sell it under the Wilma name. As I understand it now, Wilma avocados are only those which he produces, which are on a particular rootstock and grafted in a specific way (with the graft union very close to the roots themselves), which allows the union to be buried a couple of inches or so below ground level. This way, the superior cold-hardiness of the above-ground portion is not compromised by exposure of a frost-tender trunk. His rootstock also has other advantages, such as tolerance of alkaline soil.

Schneider's reason for trademarking the Wilma name (along with others that he sells) is that if someone else were to graft scions from his trees in the more traditional way, say several inches higher on the rootstock, or onto less cold-hardy or otherwise inferior rootstocks, and sell them under his trademarked names, they could not be expected to perform as well as his trees, and might well damage the reputation of his particular product.

I was worried that I might have impinged on his trademark by sharing grafted plants and cuttings from my Wilma tree (which was purchased at his nursery), but he said anyone can propagate it any way they see fit, and even sell it, but they can't call it Wilma--they have to come up with their own name. So, if I understand it correctly, a trademarked plant is less restrictive than a patented plant (such as Peterson Pawpaw cultivars, which are illegal for anyone but Peterson or his authorized agents to propagate), but only the owner of the trademarked name can legally apply that name to plants propagated from the named variety.

UPDATE:

The Wilma avocado tree produced a lot more fruit this year, so I thought I'd share some info.
[2016_11_18_Wilma_fruit_7956_rdc] 

The quality is very good, and friends/family who have tasted the fruit have been pleased with it. In general, the longer it hangs on the tree, the better it gets--unless the skin has been damaged, which causes the flesh to dry out.

Cold damage has been minimal since I planted it, but we've had fairly mild winters.

The tree is a very fast grower, and needs more room than I've given it. 

Negative points:

It's only available from Devine Avocados in Devine, Texas, and they don't ship out of state.

The thin, edible skin is easily damaged by wind, birds, and rats.

Because the skin is so thin and delicate (similar to a tomato's), the harvested fruit can become somewhat dried-out if it's picked too early.

The thin skin is impossible to peel without wasting a lot of flesh, so it's best to eat the peel, which tastes fine, but makes for odd-looking guacamole.

There is typically a round, thin spot (visible on lower-right fruit in photo) at the base of each avocado where the flesh is gray and hard; I trim this away.

The papery seed coat doesn't stick to the seed, so it must be picked off the flesh--easy to do with a pair of tweezers, but still an extra step.


I'm looking forward to comparing Wilma to other varieties, and have Aravaipa, Mexicola Grande, and Wurtz (aka Little Cado) in pots ready to plant in the spring. My Opal produced its first fruit this year, which was pretty good but harvested too early--so I'll know more about it next year.

It's good to see this old thread. Now that several years have passed, I need to modify my previous comments with regard to insect-caused souring in my yard:

Black Madeira (from UCD 2010; heavy FMV. In ground); prone to souring.

Black Mission (from local nursery. In ground); good growth, excellent, no souring.

Black Mission NL (from Encanto 2010); superb quality, no souring, but tree died due to root problems. Saved air layer in time to try again.

Conadria (DFIC0005 from UCD 2010. In ground); prone to souring.

Desert King (FJ, 2014); good, no souring--too early for beetles.

Excel (DIFIC0020 from UCD 2010; In ground); prone to souring.

Hardy Chicago (from Cathy 2012); prone to souring.

Ischia Green (DIFIC0052 from UCD 2010. In ground); prone to souring.

LSU Gold (from Cathy 2012); prone to souring.

LSU Improved Celeste (bare-root from JD 2012); prone to souring.

LSU Purple (sucker from GF 2011. In ground); prone to souring until late in season when few figs are left, but insect activity has declined.

Marseilles VS (from vicki; originally from Encanto); prone to souring.

Panachee (from Mike G 2014); still small, but few mature fruit last year were sour.

Tena (DIFIC0021 from UCD 2010; prolific, sweet, prone to souring, ant damage and splitting—likely discard)

Unknown Georgia White Hybrid (from GF 2011) Outstanding, but prone to souring.

Violette de Bordeaux (DIFIC0063 from UCD 2010); extremely prone to souring--100% loss.


At this point, my only completely reliable varieties are Black Mission and Desert King, although I'm still trying a few other varieties that aren't mature enough yet to be certain how they'll perform.

Nice photos everybody! Persimmons, especially Hachiya, are high on my list of favorite fruits--fresh or dried. Unfortunately, I had very little production on my trees this year (Hachiya with 3 other varieties top-worked onto it, a young Saijo with Ormond grafted on a couple of low branches, and Fuyu)--very few fruit, and most of it smaller than normal. Here's hoping for better crops in 2017!

Well, from my personal perspective it at least sounds like a pretty major overkill, but to each his own. I'm coming at it from the standpoint of having studied and worked with snakes for many years--in a venom research lab, as a reptile keeper at a zoo, and in the field. I've been bitten by many, many non-venomous snakes, which typically cause less damage than I get picking blackberries, and I'm willing to put up with a few scratches. But--I understand that many people don't share my affinity, and I don't expect to change their minds. When I find rattlesnakes in my yard I relocate them, but I don't recommend that approach to anyone lacking the proper experience or equipment. When I find nonvenomous snakes in my yard, I'm very pleased, because I like them and understand that they pose no threat worth even considering.

I posted last year about an easy-to-make trap for dealing with these beetles, using rubbing alcohol as bait: https://figs4funforum.websitetoolbox.com/post/easy-beetle-trap-7542388

I have since refined the design a bit and made it more effective. With two traps I caught hundreds of beetles last year. Unfortunately, since they are such strong fliers and can detect the smell of fruit from long distances, they come from all over and my traps didn't make much of a dent in their numbers. They still destroyed most of the fruit, and what they missed was ruined by dried fruit beetles or birds. This year I haven't even tried to protect the figs--birds and bugs are getting it all.

I often see birds land right in the trees while I'm picking fruit. It usually doesn't take long for them to get used to something, and ignore it. Maybe the air man approach will deter some, though. Good luck! Please let us know how it works out over the long haul.

I built a large enclosure over many of my trees (I made posts about it several years ago) and it worked great once I got small enough bird netting. However, it only lasted a little more than a season before UV and wind shredded the mesh. My trees are currently unprotected, and the birds/beetles get pretty much everything--I'm watering them to keep them alive in hopes of a future solution. I think the only permanent answer to the non-insect pests is a metal mesh enclosure with a maximum opening size of 1/2"--but that's probably more expensive than I'm up for at the moment. Maybe one of these days.

I've never watched this process so I can't say first-hand, but someone in the education department where I worked several years ago told me they separated large quantities of juice from the pulp by freezing the fruit and then piling it in a colander lined with paper towels, over a bowl, to thaw. I don't know whether they sliced the fruit before freezing it, but I think that would help. As it was explained to me, freezing ruptures the cell walls, and as the fruit thaws, the juice runs out and leaves the spines/glochids behind, trapped by the paper towels.

If you can keep the birds away, it's probably best to let the astringent varieties, like Hachiya, ripen/soften on the tree, or get really close--but I pick a lot of them hard and let them soften indoors, and they're still very good. Fuyus and other non-astringent types are good hard or soft.

Subject: OT - Got Fuyu Persimmons? Replies: 63

I dry both Fuyu and Hachiya. Both are good dried, but the Hachiya are literally like candy. I prefer to wait until they are gooshy ripe, then cut them in half lengthwise, scoop them out of the skin with a spoon, and then slice each half once more to make thinner pieces for more even drying. They're sugary-sticky, so a light shot of PAM on the dehydrator tray will make them easier to peel off when dry.

A couple of generous forum members gave me the opportunity to do some persimmon grafting. One shared scions from his various cultivars, and the other sent a dozen or so seedlings (for rootstocks) left over from his large-scale grafting project. Since the scions arrived before the rootstocks were ready for grafting, I top-worked the scions onto my mature Hachiya, simply as a place to store them. The following year, when the seedlings were ideal for grafting, I clipped new scions from the established grafts, and grafted several new trees for myself, friends and family. Most of the original grafts are still on the Hachiya and doing fine, although one variety (Eureka) didn't survive its second year. I did graft several of one type onto the tree, just as insurance.

Here's a post from back when I was first starting to graft, describing the steps I used:

http://figs4funforum.websitetoolbox.com/post/simple-stepbystep-grafting-5830743?

I am sure there are other methods that will work, but I found this approach to be quite reliable and easy. Here are the original instructions I learned from--they are better than the description I posted, and far more detailed. However, to see the photos you'll need to register with the Citrus Growers Forum:

I've grafted a few other varieties onto my Hachiya. It's pretty easy, and might be a work-around solution for a tree that isn't producing. At any rate, it's fun to see the different types, and compare them. For example, these are Saijo (first season producing--I hope they're bigger next year). Saijo, Tamopan, and Matsumoto are all grafted onto the upper branches of my Hachiya, and are producing.

I don't believe cuttings will root. I tried to air layer one once, and it didn't work. Your best bet is to buy one from a nursery, or get a seedling and graft your own. There are lots of people willing to share scions but first you need a rootstock.

Thanks for sharing the photos, everybody! Persimmons (especially the astringent types) are very high on my list of favorite fruits. Peter C, if you don't have a bird problem, you might try leaving your Hachiyas on the tree until they begin to soften. They tend to ripen quite well even when picked rock-hard and left to soften on the counter, but to me they develop a sweeter, better flavor if left on the tree until they start to soften--or at least till they turn bright red-orange.

I tasted the first ripe Wilma this morning, so here's the report. Since the ones I picked earlier had started shriveling on the counter while I waited for them to ripen, I put this one in a Tupperware with a slightly moistened paper towel. I think it was still a bit too early because it took a week or more to soften, and this morning when I checked it there was a dark moldy spot, which I trimmed off. I thought the flavor was good, but it wasn't the best avocado I've ever eaten. The texture was a little denser and stickier than what I buy in the grocery store, but that could be a result of being picked a little too soon.

I had worried about the loose seed, since some say that indicates a bad avocado, but then I read that the Mexican varieties often have a loose seed and it's not a problem. The thin seed coat sticks to the fruit but lifts off easily--however, I'd prefer not to have to fuss with picking off the pieces. I also wondered whether the black, edible skin would be bothersome, but it's fine--much like a tomato skin, I didn't notice it in my mouth. I mashed some of it up with a fork to see how it would look as guacamole, and the bits of skin didn't bother me.

I'm interested to see how the rest of the crop ripens--a recent storm thrashed them around and damaged the skin on most of them.

Smyfigs, unfortunately I'm no authority on avocados, but if you've still got green leaves or branches I'd guess your chances for recovery are good. You might want to rig some temporary shade, and if the foliage is still wilting maybe do some pruning to try to balance the amount of moisture being lost through the leaves with the amount being taken up by the remaining roots. With a young avocado graft I sometimes keep it tented in a plastic bag to keep the humidity high until the vascular connection between the rootstock and scion is strong enough to keep the leaves supplied with enough water--maybe you could make some kind of tent around your tree if it seems necessary, but take care not to cook it in direct sunshine. Good luck!

I have a few marginal plants (mangos, cherimoyas, lychee, small avocados) I'll likely need to protect from freezing during several nights this winter. I made a stand for them on casters so they can be easily rolled across the patio and under the eaves, against a window. I put in a few screws to quickly anchor the grommets of a tarp, and now I can cover everything in just a couple of minutes. Our inefficient, single-pane casement windows will undoubtedly radiate enough heat to the great outdoors to keep the plants well above freezing, and who knows--maybe the tarp will even reduce drafts in the house! I did a dry run this morning to make sure there won't be any problems some cold evening when I'm in a hurry:

My parents had a Hachiya in their back yard in San Bernardino, Ca. It didn't get any special care beyond watering, and it fruited regularly and heavily. It's probably 50 years old now and as far as I know (the house was sold a couple of years ago) is still very productive. No idea why your tree isn't fruiting, but maybe you could check with your local extension, or a good nursery, to see if other people in your area are successful, and ask what varieties work best in your local conditions.

I also tried air-layering  my Hachiya. No luck--just a  big knob where I hoped to see roots. They are very easy to graft, though--I've had excellent success using Joe Real's "bark graft" technique. Joe Real's bark grafting tutorial I think this link will work--if not, google it. You have to register as a member of the Citrus Growers Forum to see the photos.

Now my real reason for posting today:
A few years ago I grafted Saijo onto a 1-gal American Persimmon seedling, and also top-worked it onto a 15+ year old Hachiya. Both trees produced their first Saijo fruits this year--dinky things maturing about the size of my thumb joint. The taste is okay, but not as good as Hachiya. Slightly grainy. So, Saijo experts--is the small size/low quality due to the young age of the graft, and will they get bigger and better with the years, or is this as good as it's likely to get?

John, yes, that raised area around the screw is what makes the coupler fit tightly into the PVC. I left the other screw in place but plan to remove it when I store everything for winter, because it serves no real function and still managed to get caught in the netting when we were setting things up--even though each screw was turned to the inside of the corner.

Mara & Frank, I wish I could offer a solution for raccoons, but (fortunately) I don't have any experience with them, although they do live in parts of Tucson. I have an electric fence around most of my little orchard to keep javelinas out--maybe something like that would work? A friend keeps rats out of his garden with a three-foot-high wire fence with a hotwire suspended an inch above the top (connected to insulators). When rats climb the fence they have to grab the hotwire to get over the top, and it sends them flying--with little enthusiasm for a second try. Maybe a bigger version would work for coons. My guess though, from what I've read on the forum, is that the only way to truly solve the problem is to completely enclose your trees in a cage of metal mesh.

PS--yes, I have tried plastic clamshell berry boxes. They work to a point, but I don't think they'd deter a raccoon for more than about 10 seconds. My main problem with them is the birds often manage to get a beak in through the ventilation slits; the fruit also seems to get pretty hot inside them, though maybe that's less of  a problem in cooler areas.

It's the "bird netting smaller mesh" from Amigoni (http://www.amigoni.com/). It's very inexpensive per square foot, but you have to buy a 13' x 820' roll for $245.

A storm destroyed the netting on my big cage and I still needed to protect the ripening fruit on my persimmon. I figured I'd make the whole frame out of 1/2" PVC but it seemed too wobbly for the uprights. Electrical conduit (1/2" EMT) seemed better, but they didn't have the fittings I needed for the corners. Then I noticed I could force an EMT coupler into a PVC side-outlet elbow (slip fit) by removing one set screw and squeezing the fittings together in a vice. Presto! Just the hybrid fitting I needed to connect EMT uprights to a rectangular PVC frame. A digging bar was used to make holes in the ground to hold the EMT vertical.

For the netting envelope I folded a length in half and sewed up 1 1/2 sides of a big rectangle (make it slightly bigger than you need), leaving the lower half of one side's seam open for a door, which I closed with clothespins. From ladders, my son and I slipped the netting over the top, like a loose sock, and rolled up & clothespinned the slack "triangles" of netting hanging down--left over from the sewed corners.

The frame is not glued, so at the end of the season I'll just dismantle it and store everything till next year.

Having side holes to prevent over-filling during rainstorms, as well as a bottom drain for occasional total drainage both sound like important features. As far as growing medium, I checked with a friend who grows a very wide variety of plants, and he recommends a mix of coir and pumice (or coarse perlite) with a little vermiculite and dolomite. If anyone is interested, here's an article he wrote about coir and how it has been improved in recent years. It sounds like the ideal growing medium:

http://www.tucsoncactus.org/html/growing_in_the_desert_column_June_2013.html

He said that bottom-watered coir might not wick moisture as high as I want, and also cautioned about salt buildup, so I decided to modify my approach with a combination setup--using a pan with float valve to ensure a minimum half inch of water at the bottom, but with a water tube running from the valve up to emitters at the top of the pot. That way, any time the pan level drops below a half inch, the tree will get watered from the top. There will be some lag time between when enough water trickles down into the pan to turn off the valve, and when it finally stops percolating down through the mix--so the pan will likely overfill a little after the valve shuts off, but in my climate that's fine. Then, every couple of months I can drench it thoroughly with the hose to minimize salt buildup.

Thanks for all the input. Larry Hall's videos have given me a new perspective, and the Mosquito Bits sound like a quick solution (raising tilapia sounds intriguing as well, but to preserve domestic tranquility I'd better not think about adding yet another project!).

Now I need to come up with a pretty permanent soil mix that functions like a big, coarse sponge--sucking up water, while leaving air spaces throughout. 
I had thought of using "Al's gritty mix" but don't think it will wick water up from the tub. On the other hand, I worry that something with a lot of organic material will decompose and compress into an anaerobic brick over time. Does anybody know of a very long-lasting mix that would provide both wicking and good aeration?

Justin, you have a great yard-full of plants! I really like your flood-table set-up--do you leave those trays filled to the same depth all the time, or does it fluctuate or even dry out occasionally? Have you tried bottom-watering for 5 gal or larger trees? Do you see it as a way to permanently maintain large, container-planted trese--maybe even in something the size of one of those giant nursery pots stacked in your yard?

I'm wondering how many inches above water level the soil will be able to wick moisture. I hope to find a soil that works like a sponge--transporting water freely while leaving large air spaces for good aeration. I like the "gritty mix" idea in terms of air circulation and not breaking down, but I think it's designed specifically to prevent water from wicking upward.

Several years ago a forum member (sorry--I don't remember whom) told of having good success with potted figs placed in a big tub with an inch or two of water in the bottom, so the roots always had plenty of moisture available throughout the heat of the day. I wondered about keeping roots constantly submerged, but tried it and my plants seemed to thrive.

I decided to expand the idea, and threw together a crude plywood tray with 2x2s at the edges to form a shallow dike, and then covered everything with a plastic sheet. I ran some drip emitters to it so the tray would fill to overflowing once each day, and put my smaller potted stuff in it. Usually by the end of the day, most of the water has disappeared, so the bottom isn't always 100% submerged:

Anyway, it's been working fine for years, with the following drawbacks: mosquitoes, and stinky, anaerobic soil in the bottom inch of each pot (which as near as I can tell, doesn't seem to hurt the plants any in my dry climate). I try to make sure there aren't any roots at the bottom of the pots when I first place them in the water tray, but often they grow roots right out through the drainage holes.

SO--my question is: Why bother with elaborate "self-watering" pots that have small reservoirs underneath? Is that really any better than just sticking a pot in a water tray, and keeping an inch or two of water in it? What am I missing?

My reason for asking is that I just purchased a 3 gal Pickering Mango, which can't survive Tucson's winters in the ground so it's doomed to stay in a pot. I thought I'd move it up to a 5 gallon container and then set it in a plastic tub fitted with a 1/4" water line and float valve to maintain an inch of water in the bottom at all times during the summer (in cooler months I'll let it dry out). I'll wrap the pot with a light-colored cloth that hangs down into the water, to shade the pot and keep it cool via evaporation. Then, I'll "cloak" the whole thing with mosquito netting to baffle the blood-suckers. The upper part of the soil will stay pretty dry but grow progressively wetter lower down, with the bottom inch always under water.  I figure the roots will grow into the zone of ideal moisture and avoid anything they don't like. Does anybody see any fatal flaws with this idea?

I'm glad some found it useful--there's another (smaller) bunch in the trap today. Maybe it's time to change the attractant. Now if there was only an effective way to eliminate large quantities of dried fruit beetles (Carpophilus spp), I'd be in business!

Those of you plagued with green fig beetles, aka green June beetles, may find this easy-to-build trap useful. I found the basic idea online but thought step-by-step directions might be helpful:

1. Cut both ends from a 2-liter soda bottle, creating a funnel. The "neck" hole needs to be big enough that beetles can easily fall through.

2. Make a plastic baffle that fits snugly into the soda bottle. I cut two rectangles from a plastic ice cream tub, with a narrow slit halfway up the center of each so they could fit together in an "X" shape.  One of the online sources said traps with bright colors at the top worked best, so I painted some decoy "fruit" dots in different colors. I don't know if it really helps, but it might!

  3. Using the wide end of the soda bottle funnel as a guide, use a Sharpie to draw a rough circle around the neck of a gallon milk jug--avoiding the handle. Then cut the circle out with scissors, taking care to stay inside your line far enough that the soda bottle will fit snugly into the hole. It doesn't need to be perfectly round--the bottle will conform to the shape. Then cut a couple of narrow slits in the sides of the milk jug, about 1-2 inches up from the bottom. These will allow rainwater to drain out.

4. The critical part is what to use as bait. In years past, I've tried similar traps with no success--using over-ripe fruit that beetles had already been eating. The online source I read recommended isopropyl  alcohol, with some grape juice mixed in. Rather than pour it into the bottom of the jug, put it in a small container with a hole drilled in the lid for a wick. I used a pill bottle with a rolled up a paper napkin for a wick. To keep it from falling  over, I stuck it in the lid of a spray can, which I snipped into a daisy shape to keep it from filling up with gunk. The snipping was probably not useful.

5. Fasten it in, or near, a tree where beetles like to hang out. Don't do what I did, and tie it to something--because when you want to dump the stinky, drippy dead beetles it's a pain to have to untie a knot. Now I use a spring-loaded clamp to clip it in place. The final step (best done after it's in place) is to put 2-3 drops of dishwashing detergent in the bottom, and then pour in water till it starts to dribble out the slits in the jug. The detergent water will quickly drown the beetles.
 

That's it. Check it every couple of days, because soapy dead-beetle soup is super stinky, and probably won't attract many new beetles. Unclip it, pull out  the funnel and dump the beetles, hose it out, and reset it. This year it was just an experiment to see if it works. It does. Now I'll start saving milk jugs & soda bottles to have a bunch of traps ready for next year.
