I planted tomatoes this year for the first time in 5-gallon buckets. The leaves are starting to turn black/spotted black. Any advice?

There's lots of videos on u-tube that address tomato plant issues and give advice on treatment options.

I've already pulled my tomato plants for the year since I got them in the ground by early March and they were fading fast in the heat of N.O.

I never have tomato plants that make it to July. By mid June they are usually done and getting disease/mold issues.

Thanks! I tried to use a couple of free pic hosting sites but the image didn’t show. I will try this one next time.

ETA: I see it’s the same one. The preview didn’t show the picture when I tried to insert the image

That’s what I did, but it didn’t show when I hit preview. Maybe I should have submitted anyway. Thanks again.

That looks like blight or grey mold, but it's hard to tell. You can try spraying with a peroxide/water mixture. If you check the garden thread, Pillage posted a link to the mixing ratio on the first page. Also make sure you aren't watering too much. If it's blight, the plant is probably toast.

Regardless, depending on where you are, this is the time of year that tomato plants really start to struggle.

Thanks. I am in Tuscaloosa. I use drip irrigation with a timer and the containers are on a gravel area inside a fence at my office. I think they get hot and the soil dries out quickly so I water them for 5 minutes twice a day (water comes out of the bottom holes in the buckets). I don’t wet the leaves, but it has rained a lot lately. Thanks for the help.

did you put enough drainage holes in the bucket?

it might be root rot or moldy soil if you didnt

Yes. Five 1/2-inch holes in each bucket.

Check around with neighbors who grow tomatoes. Nextdoor page or facebook. The blight will usually hit everyone in the area. At least that's how it worked at my old house. Everyone's tomatoes would just suddenly start drying out and going to shite by mid-summer. If all the neighbors' tomatoes are doing just fine and it's only yours getting killed, then you might have something fixable.

You've got "blight" on them which will kill them. Usually you have to spray them with some chemicals (garden center should have what you need). However, they say nowadays they recommend destroying the plants because blight spreads very easily.

Best way to prevent it is get tomato plants that are blight resistant. A lot of the "heirloom" tomato strains are not resistant.
