The shock can cause the bottom few leaves of the plant to turn yellow. Luckily, this is just a short phase of adjustment. As long as the new growth is green and healthy, there is no cause for alarm. The yellow leaves will eventually drop off and the plant will return to good health.

This of course begs the inquiry “Why are my plants leaves turning yellow and dying?”

An answer is that nitrogen is an essential nutrient for proper plant growth, and so leaves turn yellow and become stunted when there’s not enough of it in the soil. Yellowing from lack of Nitrogen usually starts from the bottom leaves then moves to the younger leaves at the top.

What is eating my tomato plants?

It is an early season pest that moves from tall grassy weeds and occasionally attacks tomatoes, potatoes, and peppers in the vegetable garden.

One question we ran across in our research was “How do I know if my tomato plants are healthy?”.

A healthy tomato plant should have dark green leaves and stems. When the leaves and stems start to turn yellow, it’s a sign that something is wrong . Take note of how the leaves are yellowing.

One source claimed that some of the bacterial diseases include leaf spot and bacterial canker. And some of the viral infections could be tobacco mosaic virus, spotted wilt, and curly top. Some of the diseases will just cause cosmetic problems like white, brown spots on the leaves. But some of the diseases are fatal to the tomato seedlings .

Avoid getting water on the stem or leaves – this increases the chance of mold, fungus, or rot on the tomato plant. Finally, the best time to water is early in the morning, when the sun is low and the air is cooler. That way, the water will go to the roots, instead of evaporating. In short: don’t kill your plants with kindness by over watering.
