I have about 5 tomato plants growing. One of them the leaves are yellow and another a few leaves are turning yellow too. The others seem fine. What would be causing this?

Possibly one of the wilts (Fusarium, Verticillium,).

Hello
Your yellow leaves could be a lack of nitrogen or sun burn or one of the many wilt diseases. If the bottom leaves go brown and papery, it is likely it is one of the wilt diseases. I suggest you water at ground level to stop the fungual spores being splashed up into the foliage, open the plant up abit by pruning out the conjested middle leaves. The air circulating will help reduce the disease. I also recommend asking your local nursery what fungicides are available to control this diseases. Sometimes there are no chemcial controls. Next year either plant a grafted tomato because they are more disease resistant and don't plant in the same spot as this years tomato.
Cheers Keen Gardener.

Suggestion is to water the plants earlier in the evening because too late watering makes the plant to wet all night! Also try a sprinkle of epsom salts around the plants befor a rain!!
