How to maintain roses in hot weather

Rose is a sunny, cold-resistant and drought-tolerant plant. If planted in a wet place, it will grow weakly and bloom less. So roses must be planted in sunny, ventilated, humid and well-drained places. When planting, apply sufficient decomposed organic fertilizer, and after planting, pour enough water. In the future maintenance, 1 time should be applied in early spring, 1 time before and during flowering, and 1 time before winter. If the weather is dry in early spring, it should be fully watered to promote flower bud differentiation; Cultivate the soil when flowering to prolong the flowering time; Prune properly after autumn to promote the germination of new branches. In this way, plants can produce more, bigger and more fragrant flowers in the second year. Roses are afraid of flooding. If potted roses are watered too much or planted in low-lying water, the lower leaves will turn yellow and fall off, and even lead to death. Prevention and control measures: ① Select the substrate with good drainage and the planting place in Gao Shuang, and timely drain water to prevent waterlogging in rainy season. 2 potted roses should not be watered too many times a day, followed by watering every day; When it is too hot in summer, water it every morning and evening 1 time; Control water in winter. (3) If the lower leaves of the rose have turned yellow, stop watering immediately. Potted roses should loosen the soil or medium around the plants and let the water evaporate as soon as possible. If the roses planted on the ground encounter continuous rainy days, dig drainage ditches around the plants to eliminate stagnant water in time.
