Basil brown edges of leaves and dying. Hi, I grow a lot of basil indoors in my office in Ireland. I had one plant and I have grown many more from cuttings. Recently, the basil has started dying. The leaves become brown around the edges, then die. I have used potassium fertiliser on them very recently (I thought potassium deficiency might be the problem) and I have also used some strong stuff to get rid of green flys: dimethoate, it says on the label.
The tomatoes varieties that existed when tomatoes were first cultivated were yellow or orange. Through breeding, the standard color of tomato plant varieties is now red. While red may be the predominate color among tomatoes now, that doesnât mean that there arenât other colors of tomatoes available. Letâs look at a few.
When tomato plants leaves turn yellow, it could be from a fungus or bacterial problem, like Alternaria alternata or other tomato diseases. If disease is the case, you will want to treat this accordingly. Sometimes yellow leaves on tomato plants mean that there is a pest problem that needs to be handled.efore you go making any adjustments, however, you should check the soil around your plants if your tomato plants leaves turn yellow. If the soil isnât wet enough, you might just be under watering the tomato plants. Yellow tomato leaves could be a sign of lack of water.
