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.
1 Remove the bottom branches of the tomato plant, especially if they come in contact with the soil. 2  Cut the bottom branches with a pair of scissors or garden shears. 3  Trim the branches right at the plant stem, but do not cut into the stem. Use a copper or sulphur based fungicidal spray to treat the tomato plants. 2  Spray the leaves until they are dripping wet. 3  It is best to use this spray when it is cloudy or first thing in the morning. 4  Avoid using it in full sun when itâs very hot outside.
