No frost exposure definitely.
After further close inspection, I might have two different issues going on. First, before I transplanted the figs, it seemed that leaves were turning black and crispy from the tip and moving toward the stem until they were all curled up. Or, some leaves would look fine one day and then the next they would just drop off. I had potted my cuttings for the first time in February and since it was April and they all had lots of new leaves, I thought maybe it was just time to re-pot them.
So I re-potted each fig into it's own small container using some of the old potting soil mixed in with compost and leaf mulch on top. Then, since the day was getting hot and leaves were starting to look wilt-y, I heavily watered each fig. That might have been too much.
Now, it seems that the black crispy problem isn't developing (though I'm still trying to nurse back the victims from before), but entire plants just become wilted and limp. I had one especially vigorous cutting that I was very excited about, but over the past 3 days it seems to have gotten weaker and weaker, until this morning, all of its leaves are hanging by its sides and soft. On the other hand, I had one cutting from before that didn't look too hot and since re-potting it has tons of new growth and is looking great.
I don't think it's salt, because I'm not sure where it would have come from (we're on well water), and I haven't seen any salty accumulation on the sides of any pots.
It probably could be nitrogen? Maybe from compost that wasn't quite finished. Actually, now that I think about it, I don't think I mixed in any potting soil with the first 4 or 5 fig re-pots and just used compost and some left over crazy dirt (soil we buy from a local lady that's completed compost basically). Then, by the time I was potting the last fig, I didn't have much compost left, so I mixed in lots of potting soil (and that one happens to be the one fig that's doing well since transplant).
So, maybe today I will try to re-pot the wilting figs with a higher potting soil to compost ratio and water just a bit. Thanks for walking me through this Steele!
