1、 Illumination

Rose is a strong light plant. It needs to be in the sun for the whole growth period. If there is no sunshine for a long time, the rose will grow in vain, and the leaves will become smaller and weak. In serious cases, it will not bloom or even die

2、 Temperature

Roses can grow normally at room temperature, but dormancy will occur at more than 30 degrees in summer. According to different varieties, the adaptive temperature is also different. In high temperature in summer, pay attention to water cooling or appropriate shading to maintain ventilation

3、 Soil

It is thought that rose flowers bloom in large numbers, so the soil is required to be loose, fertile and rich in organic matter. We can directly buy the culture medium on the market or configure loose and fertile nutrient soil ourselves

4、 Moisture

Rose has high requirements for water. It can't be too waterlogged or too dry. It should be controlled reasonably. If the water is insufficient, the flower will dehydrate, and if the water is too much, it will turn yellow and fall off

5、 Pruning

When the rose is about to wither after flowering, it should be trimmed. At this time, the petals have changed color, and the outer petals have begun to fall off, so it should be cut off in time. When pruning small flower roses, use scissors to cut the place where the next leaf is drawn, so that the branches and buds will grow again and open new flowers. If it is a large flower rose, you should count down from the flower. Cut off the first five leaflets and leave the second five leaflets

Rose has a characteristic that the cut after pruning should be retracted by half to one centimeter, so when pruning, leave a distance for the branches to adapt. Don't cut it below the bud, otherwise it will affect the growth of the next branch and bud

It's the time to prune the new bud of rose, which is called "cool summer", and it won't differentiate. When the weather is cool, cut off the blind buds and send out new buds again, and then they can continue to bloom. When falling leaves in winter, Chinese rose flowers should be re cut. The branches and buds born in that year must retain two to four branches and buds, and all other branches should be cut off, so that they can grow stronger branches and bloom more vigorously in the coming year

6、 Diseases and insect pests

There are still many diseases and pests in the growth process of rose flowers, such as powdery mildew, black spot, aphids, caterpillars and red spiders, which will cause damage to them, so we should find them in time and treat them with drugs. Generally speaking, the effect of prevention is far greater than that of treatment. Try not to let serious diseases attack

In addition, compared with weeds, rose flowers are far from competitive. Once weeds are found around the plant, they should be cleaned up in time
