Figs not maturing and falling off
I have a problem and need help! I have a ground planted, 5/6 year old fig (I think that it is a Brown Turkey & was a cutting off a 25 foot tree in eastern Mass). Initially I cut all the offshoots off to gain height. Within 2/3 years it was six feet tall. The first year, I got two figs. I picked the first one too early (I didn't know any better) and waited until the second one was near to rotting on the stem. It was the most delicious fruit that I have ever eaten! However, I have since, let the tree bush out, with no pruning. Each year, in December/January, I return to the Keys to find the fig bush dormant with no leaves. For two South Florida Winters, I watered it daily. It became flush with large, rich green leaves and produced more figs each year, but the figs would grow to about half size, seem to mature (a color change observation) then wrinkle up and fall off with no edible flesh. The slightest touch would frequently cause even the green ones to fall off. This year I added a very moderate amount of citrus tree fertilizer. Many more figs, five dozen (?) or so, but all change to a mature dark brownish purple at half size and fall off. None are edible. I had added about two cubic feet of garden soil and peat moss (from Home Depot) when I first planted the tree. The ground otherwise has no soil, just a normal limestone island upon which we live. The bush gets direct sunlight 90% of the day. I have a potted two year old "Paradiso" fig that, with the same watering and fertilizer has produced two very good figs and two more will mature soon. No problems with falling off. Any suggestions? Thanks for your help.
