I hope you get some answers from the experienced gardeners on here. I know I would benefit from having some more knowledge on these topics.

I'm going through the same problem. This weather is unusual.

I have a large raised bed with one tomato plant which has tripled in size. Pulled off a few tomatoes which were starting to rot. Noticed powdery mildew.

I am going to remove some branches which have mildew and leaves.

There is not much you can do. Good air circulation would prevent it but I can't put fans outside on the lawn. On the other hand, my beets and carrots have exploded as has my herbs.

Having moved here six years ago from NY where I had a large garden, growing in Florida is a challenge.

Almost anything you want to know is somewhere on this forum so I would recommend some reading and searches. Container gardening is a good start a lot of us do it for many reasons.there are some pointers. First you need to look up the university of Florida planting schedule. Know your zone. Look up on university of Florida site what type and cultivar is proven to work for your zone.learn your microclimates.example I grow my tomatoes on the east side of my house.they get good morning sun and afternoon shade. since you grow in containers consider moving your plants. Blossom end rot is usually a calcium deficiency.egg shells crushed works good long term.short term tumms antacids crushed 1 tablet per gallon of water.then water plant. Powdery mildew can be treated with any antifungal.

Treimink,

I believe it is too hot for the tomatoes now. Temp gets near 80 at night and the stop blooming/producing.

That's kind of like asking which seeds to start outside in November up north. We're approaching the end of the growing season right now. Craig is right that there's no point in starting tomatoes because it will soon be too hot for anything but everglades-type tomatoes to set fruit.

In summer, if you want to keep going, in S FL it's things like okra, long beans, malabar spinach, callaloo, and other tropical vegetables. The problem isn't just the heat and humidity per se; it's all the pests that love our hot, wet summers. Most people decide it's not worth it and treat the summers down here like the winters up north. Time to clean up and clean out and then plan what you'll start later in the summer for fall planting.

Summer is a great time for tropical fruits, though. You might spend this summer exploring them to find ones you like, if you have room for a fruit tree, even in a container.
