Rose rose black spot disease is caused by the pathogen Diplocarponrosae of the genus Coleoptera. It is the most common disease of rose cultivation(seed starting trays wholesale). It started to occur in the middle and late May, and the most serious disease occurred during high temperature and high humidity.(cheap large plastic planters wholesale)
Occurs in leaves, petioles and stems(plastic plant trays wholesale). When the plants are infected, the leaves appear black round lesions, especially the mature leaves close to the ground are most damaged. The leaves of the rickets will gradually yellow and fall off. When the disease is serious, most of the leaves are Shedding, can not be used for photosynthesis, resulting in poor birth(3.54inch plastic plant pots). The primary task of controlling rose flower black spot disease is to maintain the sanitation of the cultivation environment and clean up the diseased leaves to prevent the fungal spores from being scattered.
Watering the leaves in the morning keeps the leaves dry and the pathogens are less prone to reproduction(seed starting trays). Pay attention to pruning to avoid clusters of leaves and leaves, and keep the plants well ventilated. It can be used for the prevention and treatment of chemicals. For example, the whole plant is sprayed at 1000 times of the Lai (Yi Li), once every 5 to 7 days, and continuously for 3 to 5 times, and it can also cure rust and powdery mildew(3.54inch plastic nursery pots). Rose rosewood powdery mildew is a fungal disease caused by the pathogen Sphaerothecapannosa.

The onset of rose flower white powder is different from black spot disease. When the temperature is low and the relative humidity is high, it usually occurs most in winter(32 cell seed trays wholesale). In general, the climate is humid, poor ventilation and lack of sunshine is the most likely to occur, so the winter cultivation of roses must prevent powdery mildew, in order to make rose fertility good.
Many people will encounter infections such as young leaves, tender stems and flower buds(square grow pots). The prevention and treatment of rose powdery mildew is also the same as black spot disease. It must be trimmed to keep the plants well ventilated and avoid planting roses in places with insufficient light, or other Isolation of plants susceptible to powdery mildew, such as: Zinnia, Dali, etc(plastic cell trays supplier). Choosing a disease-resistant variety can reduce the threat of powdery mildew, or use the free-absorbent (Yi Li) 1000 times to spray the whole plant.
(cheap large plastic planters wholesale)The method of fertilizing orchids is as follows: First, in the growing season(large plastic terracotta pots), newly sprouted or cultivated orchids require a large amount of fertilizer when they sprout new leaves. How to fertilize potted orchids scientifically is an old problem and a real problem that is now in front of you(200 cell seed trays wholesale). The application of the same concentration of fertilizer should be based on the health status of the orchid, the size of the orchid, and the number of orchids.
