MY Chic Hardy are larger than THIS YEAR’s Celeste and Brown Turkey, but I think they are usually almost the same size. But I get some fairly good sized C.H.'s, especially the first week or so that they start to produce. And my bushes are just gigantic this year in spite of being frozen to the ground just 2 years ago.
I feed all my figs a pretty heavy dose of 15-15-15 and they love it, even though I know some people don’t recommend that. I fertilize like crazy in the early spring and and keep reapplying about every 3 weeks until about the first week of July. I learned the hard way that if I keep pouring on the fertilize all the way up until the usual harvest time, my figs just won’t ever ripen. I used to post on here asking if anyone could explain why my C.H. figs would just stay green and not ripen all the way up until frost. Finally someone ask about my fertilize schedule and suggested that I might try not fertilizing or at least stopping a month or more before when harvest should be. I did that the following year and it completely changed everything. I have a LOT of fig trees/bushes so I’ve done a lot of experimenting on individual figs by not fertilizing, fertilizing really heavy, fertilizing only once per year and twice per year, stopping early, stopping late, etc. Again, I know others feel differently, but what works best for me at my location with my plants and my dirt and climate is to fertilize quite heavy with fairly strong fertilize (triple 15) and apply it from right before dormancy ends until early July, and I even like to throw a last feeding when they have almost stopped producing . When I do that the growth in the spring is definitely better, perhaps because they store their last meal in the roots?
Anyway, you asked and I told. Doesn’t mean my way is the right way by any means, but for me and my location, I have done more fertilize experiments on figs than anything and this is what works for me.
