I met another local gardener through an online board game but he was unable to offer advice on wilt disease prevention. Do you have any actionable advice on how to prevent fusarium wilt and/or verticulum wilt? I’m inexperienced with Lemmy so if you can’t view this screenshot easily, I’ve transcribed it below:
I had a gardening question if you grow tomatoes
I have tried about 12 different tomato cultivars (medium to large sized, for sandwich slicing) and they all die halfway into their life cycle due to the 2 common wilt diseases in Florida’s hot humid weather
My best attempt was with better boy hybrid but I only got about 8-10 tomatoes and they were not big & healthy but undersized due to the struggling plant
I can do fine with cherry tomatoes (supersweet 100s and Everglades tomatoes) but I’ve never been a successful tomato gardener and have tried all the tips such as well draining soil, mixing in compost, watering at the base so the leaves don’t get wet, etc…
I have not bothered with hydroponic soil-free substrate but I bought 2 giant boxes of it a few years ago and still have it (coco coir and perlite) but it seems too much ongoing effort even if I got 50 tomatoes or more per plant
I also bought 200 rockwool cubes and might consider starting them in soil-free substrate and then transplant them when they are a foot tall, so they have a head-start at dealing with wilt funguses

I’ve only had success with cherry tomatoes. I can never grow full-sized tomatoes due to fusarium wilt and vertiulum wilt, even after spending dozens of hours watching youtube videos and reading forum posts and extension office newsletters on how to fix it. But I live in a rural area and there’s at least 5 massive tomato fields within 30 miles of where I live in Florida (by commercial growers) so it’s absolutely possible but I just don’t know their secret. 😣
