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.
Tomatoes grow in a range conditions and climates, but good soil is essential for a bountiful harvest, and an important and easily overlooked aspect of soil quality is pH. The pH of soil, which refers to its acidity or alkalinity, is important because it affects the availability of nutrients to plants. Tomatoes, like most garden vegetables, prefer neutral to slightly acidic soil, with an ideal pH range between 6.0 and 7.0. If you don't know the pH of your soil, you can purchase a soil test kit at most garden stores.
