Roses need frequent cultivation interventions but fertilizations, pruning and watering are not the only interventions they need; it is therefore essential to know all the operations to proceed with the care of roses. The stems and leaves must in fact be checked from time to time to check for insects, parasites and fungi that could attack the plant and compromise the health of the roses. Oidium for example is one of the main diseases of fungal origin that affects roses. It is a fungus that proliferates in an important way during wet periods and with temperatures between 15 and 15 ° C. Also known by the name of white mal because of the powdery form with which it appears on the infected leaves, powdery mildew expands very rapidly during periods of proliferation and to combat it requires sulfur-based treatments which should be sprayed into aqueous solution on the leaves. Another pest to fight that often appears on the leaves of roses is the aphid. Aphids also have an extremely fast spread on the plants and must be fought quickly before they spread inside the rose garden. To combat aphids there are several products on the market that, sprayed in aqueous solution on the buds and other areas where aphids are present, make it possible to contain the infestation and fight these pests.
