The tree produces so much fruit each year, but the fruit always splits. We live in Louisiana, have many fig trees, and this is the only one to have split figs.
Fig splitting is usually the result of sudden changes in pressure brought on by cool temperatures, high humidity, or excessive moisture as the fruit matures. It may also result from excessive pollination and the growth of too many developing seeds. However, this is not considered a major problem.
I'm just curious why. . . about a gallon of LSU Gold figs were ready (I picked and preserved about 5 days ago) and the rest of the tree looks normal (figs won't be size or ready till first week of July). Also, my tree is about 15-20 feet tall. Should I fertilize it? What type and how much fertilizer?
In the right environment, fig trees will produce two crops a year, so this is not uncommon. Most likely, there were some immature fruit on the tree at the end of last year that came to maturity early this season for your first harvest and you will get another later on.
You can fertilize it with a fertilizer that is a bit higher in phosphorus, but really, if it looks healthy and is producing well, there is no need to.
I ordered two fig trees online recently. One is a Jack's Black and the other is an LSU. They are in planters, both have the same soil composition - potting soil, manure, perlite. Both are in the same size pot and get the same amount of water and light. The Jack's Black is doing extremely well and growing new leaves. The LSU has done nothing. When I got it, it had 3 small leaf buds on it. One month later, it still has the same three buds that have not grown at all. No other leaves are forming on it either. It seems to be dormant. What should I do?
Jack's Black fig is rated from zone 5 and LSU is zone 7.
I suspect it has not been warm enough for your LSU Fig tree to grow.
Try moving your plant to a more sheltered and warmer area of the garden.
