Should you cut the bottom leaves off tomato plants? As the plants grow, revisit them regularly and keep the bottom 6 to 12 inches bared. Trim away these lower leaves and stems while they're small, rather than letting them grow. This conserves the plant's resources, and a smaller pruning wound creates less opportunity for disease to enter.
What causes the lower branches of tomato plants to turn yellow?
Calcium and iron deficiency can cause younger leaves to turn yellow. In addition to yellow leaves, calcium deficiency can also lead to blossom end rot, where the bottoms of tomato fruits develop large brown or black spots. A lack of iron will cause tomatoes to develop yellow leaves with green veins.
How do you fix brown leaves on tomato plants?
Improve the drainage of the soil by amending with organic matter and reduce your watering if the soil seems waterlogged. Also, water early in the day at the base of the plant, not the foliage, to deter any fungal diseases, which will surely turn to brown spotted leaves on veggies.
What does blight look like on tomatoes?
Early blight symptoms usually begin after the first fruits appear on tomato plants, starting with a few small, brown lesions on the bottom leaves. As the lesions grow, they take the shape of target-like rings, with dry, dead plant tissue in the center.
