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.
What causes tomato plant leaves to turn yellow? Yellow leaves that have purple, distorted veins are a sign that psyllids have infested the tomato plant. Treatment involves looking on the bottom of leaves for insects, removing them and applying a pesticide to the growing area. Tomato plants that stop growing and turn yellow all over may have the curly top virus. The beet leafhopper transmits this disease by jumping from plant to plant.
