Lynzie, It's hard to be sure what is going on from the information you've given. But it sounds as if the wilting might be from fungus attacking your cuttings.
What size of containers, and what type of mix are you using for rooting? How wet does the mix get? How big were the cuttings to start with, and is it the new growth that is 4 inches? Are they in a warm spot in high light? Have you seen any evidence of roots?
Sometimes fig cuttings will send out new growth without having rooted. Fertilizing won't do any good if that is the case.
Figs root easily and rooting powder isn't usually recommended. There have been reports of it doing more harm than good. But the most common reason for failure is water retentive mix. A very light, airy mix that only stays moist (not wet) like pure vermiculite, or a high percentage of perlite gives the best results. Too much wet mix causes many rooting (rotting) problems. The smaller the pot, the better. Many people use tall plastic soda cups, or water bottles with the tops cut off. You might want to knock one of the wilting ones out of its container to see what it is doing under the soil.
I hate to loose cuttings, too, but since these are from your own tree, you can air layer this summer and replace them if you have to.

Thanks Fignut...I did take the one wilted one out of the
pot..it's only about a 6" pot for all the cuttings...and
there is a root or two. I didn't want to poke too much to
get off all the soil. The soil is just regular potting soil...nothing special. Anyway, I replanted it again but not
until I wrapped a warm sand filled neck brace around the
pot to heat up the soil a little. A good idea...you can heat
it up in the microwave and it holds the heat for some time.
It's been very cold here in Ct. and my kitchen is only about 54 degrees at ight. I'll see if that helps in the morning. I might have to replant with what you suggested. Glad to know that fertilizing isn't a good idea. I'd hate to lose these little guys even though I'll have more next year. Thanks a million for your good advice. Best, Lynzie

Hi Lynzie,
I'm in CT also. Are you by any chance close by? I'm in Greenwich. There have been a few people posting here from CT but they have all been far away from the Eastern part of the state.

I usually have a very good success rate with cuttings but just a week ago I very carefully repotted some cuttings from vermiculite to potting soil. They all had big root systems and good top growth. A couple of them just went limp, lost their leaves and died. This never happened to me before and I have no explanition for it either. Everything was the same. Some thrived, a couple died.

I know how you feel and it is discouraging. I have my email posted if you wish to use it.

Good luck,

Peg

You mentioned " The smaller the pot, the better."
The discussion in another active thread is looking for sources for 32 0z to 20 oz clear plastic glasses or pots. When you say the smaller the better, what smaller size do have in mind.
I have not been able to find any source yet for bigger than 16oz clear plastic glasses.
Also, I will get headache if I leave this question inside my head; what is the rationale for "the smaller the pot, the better". I thought the rooting mix in the bigger one may remain moist for a little longer.

ottawan, That's exactly the problem - the rooting mix in the bigger one may remain moist a little longer.
Fig cuttings can be tall, so you need a tall pot. But most tall pots are also wide and therefore hold a lot of mix which takes a long time to dry out. Fig cuttings like air (which water displaces), that's why we are using light airy rooting material (which drains well and doesn't hold much water).
So we're looking for clear (so we can see what's happening),tall containers that we can burn or poke holes in (without shattering them), that DON'T hold a lot of mix. We're looking for bigger cups because they are taller, not because they hold more mix.
I went nuts last year trying to find tall cups and ended up with the 1 quart deli containers, which were too large for my taste. I finally asked everyone I knew to save me water bottles. (One way to find out if a friend is REALLY a friend, LOL.) They are a great size, but have the disadvantage of having vertical sides - the "pots" have to be cut off. I found it's easier to cut through most of the bottle before potting, leaving uncut bands to hold them together, and then just snipping the bands when removing the fig tree.
