Yellow, curling, mottled leaves on my potted tomato plant. What is it?

(Winterset, IA)

Q. How do I treat yellow, curling, mottled leaves on my potted tomato plant?

A. Yellowed leaves by themselves could indicate under-watering, over-watering, a nutrient deficiency, various wilts (such as fusarium wilt, verticillium wilt, or walnut wilt, infection from a pest such as aphids or white flies, or one of several fungi diseases.

But with the mottled foliage along with yellowed leaves, there's a good chance your plant has acquired either early blight or Septoria leaf spot.

Both are caused by fungi that over-winter in the soil.

Early blight causes leaves to yellow, curl, and develop dark spots with concentric rings. Fruit can also develop spots.

Septoria leaf spot shows first on lower leaves with yellowing, curling, and dark spots. Septoria begins on lower leaves and works its way up the plant. Fruit is not affected.

Both early blight and Septoria leaf spot can be treated with copper spray, a biofungicide (like Serenade) or a fungicide (like Mancozeb or Fungonil).

But prevention is the most effective way to offset tomato blights of any kind, including early blight and Septoria leaf spot. Be sure to fill containers with sterile potting soil at the beginning of the season. (Fungus for both early blight and Septoria lives in the soil.) Plant blight-resistant varieties. Mulch plants to prevent water from splashing up on leaves and spreading fungus. Avoid overhead watering. Rather, water with a drip hose at the soil line.

Good Luck and Happy Gardening!

I think it would be some nutrient deficiency as there is a lot of yellow leaves to be spotted around the pot. The main thing that has to be done here is to prevent this from further spreading and diagnose what exact deficiency is this. Beverly Diamonds Reviews

Tomato issues NEW
by: dew

I have 3 container plants, each with a different type of tomato plant. 1- San Marzano 2- Burpees Big Boy, 3- Grape tomatoes. The burpees big boy has tomatoes on it or varying sizes but seems to have stopped growing. The fruit is turning red. There are a lot of yellowing leaves on it.
The San Marzano, same thing. The grape tomato plant is 7' tall, has tomatos on it and no yellow leaves.Its like 1 or two stems that have grown very tall. I water every day that it doesnt rain. All my pots have drainage and I fertilize weekly with organic GardenTone for vegetables (watering and feeding instructions from a friend)
They all get about 5-6 hours of full sun a day.
What am i doing wrong?
