How to prune roses after they bloom
Roses are beautiful flowers, but they need careful maintenance to keep blooming. Today, we talk about how to care for flowers after flowering.
Many people like roses. Whether they cultivate roses in pots at home or plant them in the yard, the plants will thrive, germinate, and bloom beautiful flowers in May every year. As long as the maintenance methods are reasonable, roses can bloom many times a year.
Today I want to share with you that at the end of the first blooming season of the year, rose diseases and pests can easily occur, especially large amounts of spider mites, black spot, and powdery mildew at the base of the plant. If not treated in time or handled improperly, there will be a lot of diseases and infections: today I want to share with you how to grow roses in summer and eliminate pests and diseases.
One. At the end of rose blooming season, protect against pests.
Reason 1: At the end of the rose’s first blooming season, the plant consumes a lot of nutrients, the flowers are malnourished and their disease resistance will be reduced. Therefore the first flowering season is usually over and the flowers are susceptible to pests and diseases.
Reason 2: Of course, it is also because the end of the first flowering season may be at the end of May and early June; this time is suitable for temperature, the disease has a strong ability to reproduce and spread, and it can easily cause damage to rose plants.
Approach
Therefore, when caring for roses at the end of their first flowering period, we must take reasonable measures to prevent the outbreak of pests and diseases, while promoting the rapid growth and development of rose buds and continued flowering.
Prune dead branches and flowers
For withered roses, pruning should be carried out in time; first, prune the remaining flowers at the top of the plant. The pruning method is also very critical. Generally, from the flower bud to the second or third bud point, the specific pruning position is that the bud point is as high as 5 mm to make the lower bud point full, and new branches will grow out soon, and the remaining flowers will bloom again. After the flowers fade, Prune promptly. On the one hand, it can reduce the consumption of nutrients, and on the other hand, it can prevent flowers from rotting and causing diseases and insect pests.
Also prune the leaves and branches at the base of the rose, especially in dense, poorly ventilated areas at the base. It is recommended to use scissors to trim cross branches, dead branches and yellow leaves to increase ventilation of the entire plant root system; thereby effectively avoiding the occurrence of pests and diseases, especially the development of red spider mites and aphid larvae.
Drug spray
After pruning the flowering roses, promptly spray the endogenous drugs chlorothalonil, furosemide and other drugs. After making the aqueous solution, spray the front and back sides of the branches and leaves of the roses every three days or so for three consecutive times; this can improve the disease resistance of the plants. , Effectively avoid the occurrence of pests and diseases: Do not spray pesticides on rainy days or hot midday.
Auxiliary fertilizer
Most rose varieties can bloom multiple times during the growth process of a year, so after the first flowering period, they should be pruned and sprayed and fertilized in time.
The topsoil of potted plants can be excavated with a flower shovel, and organic fertilizer, such as fermented chicken manure or rabbit manure, is evenly sprayed on the potted plants, and then buried. This can accelerate the growth of rose branches. Spray 0.1% potassium dihydrogen phosphate solution on the branches of rose leaves every 20 days to supplement phosphorus and potassium fertilizers, which can promote the germination of buds at the top of the branches.
By using this method to grow roses at home, they can not only grow luxuriantly without pests and diseases, but also bloom multiple times, usually from May to September, which is very spectacular and beautiful.
All flowers need to be pruned so that they will bloom more beautifully next year. The pruning method is as follows:
1. Choosing to prune after the flowering period can help the wound recover faster.
2. Topping is required to prevent the hydrangea from growing too tall. When topping, choose an angle of 45 degrees.
3. Withered branches and leaves need to be pruned in time, and the cut dead branches should be thrown away because there are bacteria on them to prevent infection of other growing branches.
4. Pay attention to symmetry, do not have more on one side and less on the other to avoid skewness in the future.
5. Loosen the soil before pruning, and fertilize it after pruning. This can promote growth. After fertilizing, water it appropriately to avoid burning the roots.
