Introduction

As a gardener, one of the most distressing things to witness is yellowing of leaves on your tomato plant. If you are wondering why your tomato plant leaves are turning yellow, then you are in the right place. There can be various reasons for this yellowing, and we will go through each of them to help you with your problem.

Pest infestations

It is the most common reason for leaf yellowing in tomato plants. Various pests, including whiteflies, spider mites, or aphids, can suck out all the nutrients and fluids from the tomato plants, leading to the yellowing of leaves. You can sprinkle neem oil on the affected plants to get rid of pests.

Environmental stress

Other than pests, environmental stress can also cause yellowing of leaves. Inadequate sunlight, excess or insufficient water, and high or low temperatures can contribute to the yellowing of leaves. Tomato plants need 6-8 hours of direct sunlight every day, so make sure your plant is positioned in a place with enough light. Water your tomato plants regularly, but do not make the soil too soggy as it causes stress to the plant. The ideal temperature for tomato plants is between 70-80°F, so make sure to maintain this temperature.

Nutrient deficiency

If you are not providing enough nutrients to your tomato plant, it can cause leaf yellowing. Nitrogen, phosphorus, and potassium are essential nutrients for tomato plants, and their deficiency can lead to yellow leaves. You can add fertilizer to the soil to provide enough nutrients to your tomato plants. However, make sure not to over-fertilize as it can lead to root burn and further yellowing of leaves.

Disease

If your tomato plant is infected with a disease, it can cause yellowing of leaves. Fusarium wilt and verticillium wilt are two common diseases that affect tomato plants. These diseases spread through soil, contaminated water, or infected seeds. If you suspect your tomato plant is infected with any disease, isolate the plant, and treat it with a fungicide. Also, make sure to clean your garden tools and keep the area clean to avoid infections.
