Causes of Yellowing Leaves

The most common reason for tomato plant yellowing leaves at the top of the stem is a lack of water. When a plant is deprived of water, it starts to wilt and the leaves begin to turn yellow.

Inadequate water can not only cause yellowing of leaves but also produce misshapen fruits and slow the growth of tomato plant.

Another reason why tomato plant yellowing leaves at the top of the stem is due to soil deficiencies. Lack of essential nutrients such as magnesium and iron can cause yellowing of leaves at the top of the plant. Soil deficiencies can also lead to poor fruit quality and reduced yield. If your soil is low in nutrients, you can add organic compost, bone meal, or fertilizers to provide your tomato plant with the nutrients it needs.

Insects and diseases can also cause yellowing of leaves at the top of the tomato plant. Infestations by spider mites, aphids, or whiteflies can weaken the plant and cause yellowing of leaves. Disease-causing fungi like Verticillium wilt, Fusarium wilt, and bacterial canker can cause yellowing of leaves and wilting. Removing diseased leaves and using fungicides or insecticides can prevent further damage to your plants.

Here are some preventative measures you can take to prevent your tomato plant from developing yellowing leaves at the top of the stem:

Water your tomato plant regularly and make sure that the soil is evenly moist. Avoid overwatering as this can cause root rot.

Inspect your tomato plants regularly for signs of insect infestations or diseases. Early detection and treatment can salvage the plant and prevent further damage.
