It's almost summer Can you live by planting Chinese roses?

Will live. Transplanting with soil balls, watering and placing in a ventilated and cool place. Or put it under other flowers and wait for the seedlings to get some sunshine.

Pot management of rose

Rose is a light-loving plant, but too strong light is not conducive to bud development, but grows in places with insufficient sunshine and slender branches. It takes about 45 days from germination to flowering, and the optimum growth temperature is 15-25℃. In this temperature range, the flowers are large and beautiful, but they grow slowly at 30℃, and the flowers that bloom above 30℃ become smaller and lighter in color. When seedlings are planted in pots for 2-3 years, they should be pruned, and old roots should be cut off to promote new roots, but pruning should not be too heavy. Pay attention to root stretching when planting. Spring, summer and autumn should be placed in a sunny, well-ventilated and stagnant place.

After Tomb-Sweeping Day, the Chinese rose was carefully pruned when it came out of the cellar. Choose the robust branches of Chinese rose to stay, and cut off other transverse branches, weak branches, cross branches and over-dense branches. The selected branches should have 3-5 bud holes from the base, and all the above branches should be cut off, so that the plants can absorb a lot of nutrients from the soil and supply the long-term growth needs of leaf buds and flower buds left after pruning. Remember to prune after germination. Pruning will affect the first flowering, and the growth height should be consistent. Each plant can retain 3-5 main branches, with a maximum of 7 branches.

Mid-term pruning mainly includes cutting off the sprouting branches of grafted seedlings, cutting off the residual flowers, thinning off the redundant buds with leaves after flowering, cutting off the delicate flower branches from the base after the first flowering, and cutting off the remaining robust flower branches under 2-3 leaves of residual flowers. The second flowering can still be pruned by thinning the weak branches, leaving strong branches and strong buds.

Prune 1 time before overwintering, but not too early. When pruning Chinese roses, we should not only choose strong branches, but also pay attention to the consistency between master and slave. Large-flowered varieties should have 4-6 strong branches, and each branch should choose one side of 30-40 cm to grow strong buds, and the upper branches should be cut off. For vines and vine varieties, remove old branches, weak branches and pests and diseases.

When the whole branch grows, there should be no buds at the top, so it should be pulled out as soon as possible, leaving three main branches for culture, and the buds on the three main branches should be pulled out in time to make the plant grow vigorously. After the branches are fully grown, the buds should be picked to make the flowers sprout. Generally, topping can bloom in mid-June 1 1, and topping can be completed in mid-June 1. For the stout branches near the ground, they can be used as regeneration branches, leaving 2/3 of the length and cutting off 1/3, and 2-3 new branches that grow later can produce better cut flowers.

Potted roses are not dried and watered, but watered thoroughly. In summer, the weather is hot and the evaporation is large, so potted plants should be watered more, especially at night, which is 1 times. When the temperature exceeds 30℃, roses will grow poorly and bloom less. Some people think that it is a bad thing to topdress more fertilizer because of insufficient fertility. In midsummer, topdressing is generally not needed, and only thin fertilizer is applied to the vigorous branches, twice a week1-. If you can get proper shade after 1 1 in the morning, you can bask in the sun after 4 pm, avoid the high temperature at noon, and resist the weak sunshine before noon and afternoon, which is beneficial to photosynthesis and accumulate nutrients for the next crop. After pruning, it can be fertilized and mixed with 50% human excrement and 2% calcium superphosphate. In mid-February, 3% human excrement or 1% urea can be used as topdressing, and urea can also be sprayed before and after the rain. Fertilization is not suitable when the new buds are red. At this time, fertilization will cause young roots to be injured, so that plants will wither or stop growing, so special attention should be paid.
