Fig in pot suddenly dropping fruit
I have a 3rd year (for me, since purchase) Chicago Hardy in a 5 gallon bucket, a mix of compost and potting soil, that has set fruit for the first time. It seemed that all was well, the plant looks healthy and I do not see any insect infestation.
The fruits have been enlarging slowly, and are still smaller than or about the size of the tip of my thumb. Two had started to color up purplish. Today I found that many of the fruits have dropped, including the two that were showing color.
The plant itself is not showing any signs of distress though -- not wilted, the leaves are uniformly green, not pale, and there are new buds on the tips of the branches.
It is on a south exposed patio, gets full sun until about 2:30 pm then is shaded.
Any ideas? Maybe this is normal (this is my first and only fig plant). Maybe it needs a bigger bucket?
