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 to Use Tomato Plant Fertilizers. Tomatoes should be first fertilized when you plant them in the garden. You can then wait until they set fruit to start fertilizing again. After the tomato plants start growing fruit, you can add light fertilizer once every one to two weeks until the first frost kills the plant.hen fertilizing tomato plants after the fruit have set, first make sure that the tomato plant is watered well. If the tomato plant is not watered well before being fertilized, it can take up too much fertilizer and burn the plant.
