Wilting of rooted cutting

Is anyone familiar with the specific cause of this.Is it a fungus or something else. Please look at the picturehttp://www.dotphoto.com/ViewAlbum.asp?AID=6724990&IID=274322209

One leaf got it first and then the other leaf. The edges curl and the leaf gets a grayish look right where it is dying. This is the second cutting it happened to. Those leaves will surely die.

Thank you

That doesn't look like wilting. Wilting is caused by a loss of turgor pressure, the leaves would be drooped and the green stem soft. Are the cuttings closed up in that tub normally?

Maybe wilting is the wrong word. Within 3-4 days or so the leaf kinda self destructs from the edges. These were originally in a closed bin but I then move them into a bin with no lid. If they show sign of stress I tape the rest of the coke bottle back on top and wean off the humidity by adding holes each day.

Yeah i'm not sure what to call it. It looks like tip-burn. 

look like to much humidity

What is your light source? If irs unfiltered light were as before it was filtered through clear plastic or anything else you may have burn. Pull light further away from container.

Appreciate the replies. Well, it was a cutting which started to leaf out in the coir. I don't know if that has anything to do with it. Too much humidity? Maybe, but same humidity as the other cuttings. I don't really think its burn from the light. They are 6500K t-5 and a good 6-7 inches away and it didn't manifest itself until 4-5 days after it was put under the light.

The only thing else is,soil is to wet. Roots die off and no moisture reachs leaves. Push soil away from cutting at soil line. Scratch cutting beneath soil line. If bark rolls off cutting will die. If this is the case cut bottom of cutting off little by little till is good.

Hi,
Looks like the cutting was pushed and now is depleted and crumbles .
Some call that "cutting sudden death".
What you can try is cut the leaves. Put the cutting in a drier environment to slow it. And hope it will have enough energy to sprout new buds in a more reasonable environment.
I often get that when growing cuttings this time of the year. That is the reason why I reverted to in-season-growing - beginning mid-march in my Zone7.
This time of the year I only use one or two own cuttings that I would throw to the compost pile normally ... to just mess them up most of the time ...
Currently, I have 3 in the basement - another one still in the flat. Hopefully they'll get some rest and can sprout back next March ... Hopefully ...

i think im having the same problem- sudden death.

it was growing fine and then, in one day, this- i may have too much water on it, but i have tried to be very careful and no other cuttings are showing these signs.

That happens to me every year, one day it looks like a picture perfect plant the next day it starts to droop and it's down hill all the way,

I was thinking the next time this happens giving them a half dose of viagra????

well, i guess the good news is, it might not be my fault. i am like a helicopter parent right now- that cant be good, especially when one does as mine did.  

viagra, huh?  i dont think it could make it any worse.  do any of these ever come back?

I have one or two plants that are doing the same thing let it dry out then water it sparely I use a spray bottle you should be fine water will kill it 

thanks dave. i'll try that.

trust me Johnny it will work it took me a long time to realize dry cuttings do better than wet cuttings

FWIW, I think that this is the right diagnosis.  The leaves seem to have outgrown the roots.

Dang. It's hard to let them go dry.  I keep wanting to put water on them when ever the top gets dry.

i do agree that the roots were probably outpaced by the leaves.  i bit off a little much this year and have been moving the cuttings from the the high humidity box to the grow area faster than i wanted to.  i'v been selecting based on root growth, but as the cuttings come out of the coir, i am now having to chose less than ideal figs to move over there. 

this has been a great help!

I have a working theory on roots being outpaced by leaves. I had a few that looked pretty sad. I put it down to the mixes being short on nutrients and not enough left in the cutting for supply. A very diluted liquid fertilizer fixed things right up. For this to work I assume there would need to be some roots in place. 

Your problem cuttings, like mine, seem to be rather narrow and short. This was the case for mine as well.....Makes me think that the smaller cuttings need a bit of help.

Or it's something else entirely....   Happy Christmas!

in my limited experience, thinner cuttings are less reliable.  The apparent reason is a lack of resources.  A cutting that puts all its energy into making leaves may not have enough left over for good roots.  Once the internal resources are exhausted, the meager roots are incapable of meeting demand from the robust leaves.  

So we should probably do what we can to suppress leaf growth and encourage root growth until the roots are well established.  For this reason, I believe (but can't prove) that it's best to start cuttings in the dark and, if possible, to use bottom heat to keep the roots (rooting medium) warmer than the leaves (air).  Similarly, the top of the cutting should be kept humid until the roots are sufficiently developed to provide adequate water.

When a cutting collapses like that it is because the bottom has rotted.

TJ and JD,

Spot on. I think i pushed this one too fast.  the roots are just starting to show in the cup.  i have been feeding with a dilute 1-0.5-1 "rooting enhancer" and providing bottom heat.

i will say, i have not been particularly proficient providing a dark environment during initial rooting.  my tupperware boxes allow some light through the gap between the media and the lid. i have planned to tape them off, but have been achieving much success until now, i just got lazy.

i have noticed- in my very limited observations- that thinner cuttings grow roots faster, but the thicker cuttings, though slower to start, grow more roots and stronger roots and fewer leaves. But i could be wrong- this is my first year growing, so i cant speak to the survival rate, but so far i am having near 100% success with rooting.  i think one of my reasons for the great success rate is buying only from member of this and the other forum and am reading and listening to the experiences of the members.  

Still no sign of recovery in the wilted cutting, but i continue to monitor.


There are plenty of roots showing in that cup, they are cut off from the top though because of rot. 

Were the cuttings trimmed to just below the bottom node? Could be a pathogen entering through the pith.

Johnny -- Some people put them on top of a warm appliance, like a fridge.  I've got mine (in damp sphagnum moss in baggies) in a warm, dark closet.  The closet has got some electrical gear that generates just enough heat.

I am convinced that sometimes you can do everything right and this still happens. That doesn't stop it from hurting, particularly if it's an expensive cutting, but it may be something about that cutting and not your fault. I had this happen with one particular variety, every single one ended up dying like this.
