I am new to gardening and am having a rough time. Here are my problems:
1)tomato blossom end rot. I am thinking moisture is the issue. We have been having unbearably hot days followed by several days of thunderstorms and it seems every time I get a lot of rain the tomatoes that fruited during that time end up rotten. I would say about 1/3 of my tomatoes are getting this. I see lots of advice on how to prevent end rot but not how to stop it, so that's my first issue.
2) pepper plants. 2 weeks ago they were blossoming like crazy, I got 2-3 fruits per plant and then nothing. The plant has stopped producing flowers. Itty bitty fruits have fallen off. The plants haven't been getting any bigger. What peppers are on there haven't grown bigger in about a week.
3) cucumbers not setting fruit. My cucumber plants have been putting out male flowers for over 2 weeks now, tons of them, yet not a single female flower or fruit. I have seen bees so I know they are getting pollinated.
What gives? I am getting really frustrated.
I am being careful to water them as needed but not overwater. The garden gets direct sun about half the day. It has been really hot and humid, if that helps.
Eric was right, your location and more about what temps you are dealing with would help.
but you said you are getting advice about how to prevent BER (usually related to adding calcium some how) but not stop it. That's because all you can do is prevent it. BER is related to what was going on at the time the fruit was set. By the time you see it, there is nothing you can do about it. But if only affects that fruit, not the plants, so if you can correct the conditions, the same plant will go on to produce healthy fruit. But I think you are right about the weather and inconsistent watering being the causal conditions in this case.
Blossom drop (like your peppers) is a stress reaction. When the plant is stressed it drops the blossoms to concentrate on survival. Peppers are usually more heat tolerant than tomatoes, but if it is hot enough especially wet and hot, that could be your stressor.
Re the cukes, you said you have plenty of bees so you know they (the flowers) are getting pollinated. But you also said the plants have only male flowers. That doesn't make any sense. Only the female flowers get pollinated. The male flowers produce the pollen, which the bees carry to the female ones (a basic birds and bees lesson!
). It is typical for cucurbits (cukes, squash, melons) to produce only male flowers at first. Probably makes sure that the bees are around by the time the female flowers show up. In this case, likely all you need is a little patience. Give it another couple weeks and the female flowers should start showing up and setting fruit.
