Coconut coir

I find this the best stuff ever for rooting. I've read about the potential problem with salt. The previous product  I used everything seemed to work out OK. The new batch, I had several rooting bins where nothing rooted, just rotted. I have no idea if salt was involved but it got me  looking for low salt coconut coir. I found Black Gold that claims to buy only from inland suppliers, away from salt water. They also claim to wash/rinse again before selling. A two cubic foot bag goes for about $50 on eBay and Amazon shipping included.  If you have a True Value Hardware near you it's only $17 shipped to store. I have one right around the corner.

Hi there. Do you wash your coir until it runs clear? The coir i used in my self watering plum and fig barrels was unwashed (ie it ran red when water was applied) and i never had issues but that was when i was new to the stuff. Ever since then i have started washing it by hydrating it and then putting it in a fabric shopping bag and then running water through it and squeezing the red stuff out, takes about 2 soakings for me. For rooting my strawberry verte and black ischia cuttings i washed it and squeezed it well. they all rooted nicely and are growing well. 

I will be receiving some coir to root some fig cuttings i purchased recently. I hope they turn out okay. I used the brunings brand here in Australia. They sourced it from Sri Lanka.




I like it for seed starting, rooting, air layers and here Home Depot also carries Black Magic. Nice product, full or perlite. I do not like it as a potting soil though. It's too wet or too dry, seedlings do OK, but once up potted seem to slow down in the stuff. I now up pot in my final potting soil mix. I make my own mix.

I use a 3-1-1 mix. I find 5-1-1 to dry for my liking. I don't use perlite, well not straight.
3 parts pine bark fines, best i can find 1/4 to 1/2 inch is ideal.
1 part pro-mix,  peat moss for blueberries. Pro-mix pH adjusts peat, and adds perlite.
1 part compost,  prevents root rot, add bacteria and some food.
1/3 part diatomaceous earth, Optisorb or Napa floor dry, both 100% DE pebbles, not powder. I also add this to seed starting mix. Holds 120% of it's weight in water, holds air for roots, won't break down, absorbs excess moisture, thus aerates soil and slowly releases as mixture dries. Lava rock or pumice do the same thing, DE does it best.

I have been adjusting this mix for years, this works for me. often i have to leave plants for a few days and this mix holds enough moisture to not stress plants out too much.

Here is a cutting from last year,, once up potted it grew to about 5 feet. Unknown Teramo.
This is a first leaf plant. Currently it's full of breba.

I don't use it for growing, only for rooting, like people use sphagnum moss. I don't rinse it cause I use it barely damp. Would take forever to dry out

I used coconut coir from gardeners supply that specifically for seedlings: http://www.gardeners.com/buy/coir-seed-starting-mix/40-135.html#q=coconut&simplesearch=submit&start=7 only two of my many cutting refused to root this year.

Would u describe how you using them for rooting? What method you was using? Do you monitor temperature?

My house was roof leak with high moisture of 60% yearly, Sun is blocked by new tall house, no gas heater,  I tried rooting with Sandwich bag/wet towel method, pure perlite, Co coir, Pro-Mix HP, 10% beach bath, at 75F warm spot, it has 100% fail due to mold.

I used same method outdoor non-direct sun area with 50 to 75% success due to  un-regulated low temperature,  I think that sunlight UV kill molds in air,  Co coir is the best for me so far.

So far, I have very bad experience growing fig trees, due to low rooting successful rate,  I end up buying couple big nursery fig trees last year and planted them in ground, I got few figs first year, this winter, I am at Zone 8B, 50% of them freezing dead to ground, new sprouts from suckers now, It will be no fig again another year, too many red tapes, E.X, hard to get cutting in Canada, cool summer, FMV mites(I find white spots on my potted fig trees now), I cut all resource for this project.

With any coir...... you have to squeeze every last bit of water out of it. A handful at a time. IF YOU DO NOT CUTTINGS WILL ROT....... SALT DOESN'T ROT CUTTINGS. IT DRYS THEM OUT. I USE COIR FROM PETSMART. 10 DOLKERS FOR THREE BRICKS BUT GOING TO BUY THE BLACK GOLD THAT YOU POSTED A LINK TO. GOOD DEAL.

I root in food storage containers, on top of a water filled under bed storage container, on top of 2 heating mats, on top of patio blocks. I just couldn't get past laying the heating mats on the combustible carpet. Those cheap dollar store containers don't have the best seal so to deter fungus gnats I store the containers in clear plastic bags and cover the whole thing with a  large towel to keep the heat in. I have a temp probe in the water. I just potted a bunch up the other day so I don't have a good pic of roots at the moment

I don't think I could squeeze it hard enough to get it as damp as I like.

Pro-Mix now has a product with Coconut Coir.  It's called Pro-Mix HpCC.  I may try some.

I just tried it this spring. I mixed it with what I had left over from last year. We'll see how it goes.

I buy the cheapest compressed coir I can find on Amazon.

I think it works.

I used Burpee coir at Walmart, it worked ok.

Botanicare lets thier coir sit outside in the monsoon seasons to get washed out...woked good.

Ricky,

Many people get figs that bear even the year they die back, and Breba is important for you just in case it does not die back with proper winter protection. Adriano should have some for you. Canada is not fig paradise, but as you know it can be done.
