Question: when, which and how to carry out lemon pesticide treatments?
I have a lemon tree that bears fruit in every two-year season poured into a soil made of sand and normal soil such that its PH must be acidic. Maybe I'm wrong, but can you tell me how the soil should be to decant a lemon and when it will be decanted? Since the plant is exposed to a Mediterranean climate due to temperature drops, does it have to be repaired in a warm environment?
I would like to understand what lemon diseases are. It tells me how I should treat them: which products should I use? When should I carry out these treatments? For some time has appeared on the crteccia like a black foligo what is it and how should I do to eliminate it? You notice that behind the leaves there are white and red dots: what are they and how should I do to eliminate them?
Answer: when, which and how to carry out lemon pesticide treatments?
lemons love a fresh, rich and very well drained soil, not necessarily acid; you can use universal potting soil, mixed with lapillus or coarse-grained pumice stone, which allow the soil to breathe, allow the water to permeate well and remain soft without compacting excessively. The fulmine you see on the branches could be gray mold, or fumaggine, caused by excessive humidity or by the presence of parasites on the leaves; the pests you describe could be cochineal, which is eliminated by treating the plant with white oil.
Lemon plants live well outdoors in a Mediterranean climate; need to be protected only in case of frost.
