Rose's ecological habits
Rose is sunny, also resistant to half-yin, more cold-resistant, and can be exposed to winter in most parts of northern China.
Rose is not strict with soil requirements, drought-tolerant, and resistant to inferiority, but it grows better in soils that are deep, loose, fertile, and drained, and can grow normally on sticky soil. Not resistant to water and humidity, avoid standing water. When the new plant is planted, it is necessary to apply the decomposed organic fertilizer.
In the first year or two after the planting of the rose, the base fertilizer can be applied once a year in the late autumn to facilitate growth and flowering. Strong and strong, resistant to pruning and pollution. The flowering period is generally from April to September every year. The order is open for up to six months. Due to the greenhouse effect, global warming occurs. In some places, the rose begins to bloom in April and even in March.
Rose cultivation technology
There are many similarities between the cultivation of roses and the cultivation of the rose, but it is much more extensive than the management of the rose. Planting plant spacing should not be less than 2m. From the beginning of the early spring germination to the flowering period, it can be watered 3 to 4 times according to the weather conditions to keep the soil moist.
If the drought is at this time, the number of flowering will be greatly reduced, and it will be re-watered 2 to 3 times during the summer drought. Pay attention to timely drainage and flood control during the rainy season. Because the rose is afraid of water, the water is easy to rotten. In the fall, pour 2 to 3 times of water as appropriate. Watering throughout the year should be careful not to allow water to accumulate in the roots of the plants. When the pregnant bud period is applied 1 to 2 times of thin pizza fat, the flower color is good and the flowering period is lasting.
Pruning is an indispensable important process in the landscaping of roses. It is not well trimmed and grows into a pile of thorns. It is not only pesty and disease, but also has an unsightly appearance. Generally, adult plants are pruned once before each spring germination. The amount of pruning should be moderate. Generally, the main branch (main vine) can be kept within 1.5m, and the rest is cut off. Each side branch retains 3 to 5 buds of the base.
The longer the plant grows, the more flowers it blooms, and the more nutrients it needs. Every winter, it needs to be fertilized once a year to keep the shoots and flower buds flourish and the scenery is gorgeous. Cultivate potted flowers, pay more attention to pruning and shaping. Cut flowers have a large number of flowers, and the flowering season needs to be fertilized 1 or 2 times a week, and attention should be paid to cultivating the flowering mother branches and cutting off the flower buds on the weak branches.
