A bafffling problem in one of my gardens
I have several gardens scattered around town. One of them is a raised bed garden situated next to a large American elm that shades it from around 11 am to 2 pm. So it gets morning sun and late afternoon sun. I have elm roots creeping into pretty much all the beds.
I planted cucumbers, cantaloupes, tomatoes, bell peppers and eggplant here in mid-June. The cucumbers took off like crazy. The melons are doing OK. The solanaceous crops look like they are barely surviving. They've lost all their lower leaves, look stunted, and have started fruiting prematurely for their size. The eggplants look particularly bad.
I thought it may be soil temperature, but it is quite warm and the melons are doing much better than the tomatoes anyway. Then I thought it may be the elm sucking out water and nutrients but it has been raining frequently, and again, the cucurbits look dark green and healthy.
Anyone want to venture a guess as to what is wrong? TIA.
