The long leaves of the rose in the family do not blossom, one inside, two outside and three pay attention to easy handling.

If you want to choose the most beautiful part of the rose, I believe that the flower will undoubtedly become the absolute champion. After all, we plant rose to see it blossom, but although it is beautiful, it is not easy to grow. Roses planted by many friends often show a healthy picture of tall and straight plants and emerald green leaves, but the problem is that they bloom little or not at all, so what on earth should we do about this phenomenon of growing branches and leaves? In fact, the way to deal with it is nothing more than six points.

Internal cause:

First of all, the internal cause of the excessive growth of rose lies in the intake of excessive nutrition, which mainly refers to fertilizer and water. First of all, let's talk about the issue of fertilizer. although it is autumn, the temperature is still very high because of the "autumn tiger". At this time, the rose itself will still be in a semi-dormant state as when it is hot in summer, so the intake of nutrients is not high. If fertilization is likely to cause eutrophication of rose, especially if we apply a large amount of nitrogen fertilizer without experience, then the phenomenon of overgrowth will be even more serious. Of course, this is not a serious situation, more serious may cause fertilizer damage, resulting in plant death.

Watering is also noteworthy. Although the temperature is high and the amount of water evaporates quickly, the rose itself has a good ability to adjust, so there is no need to worry too much for a while. But some flower friends are afraid that it is "thirsty" and water it many times a day, which absorbs too much water, which is not conducive to the growth of the plant. According to the principle of seeing dry and wet, it is most appropriate to take the actual situation of the soil as the basis for watering.

Two external causes:

1. Lack of necessary pruning links

Autumn is the rapid growth period of Chinese rose, so it will grow a lot of branches and leaves during this period, and once the plant has too many branches and leaves, it will lead to nutrition dispersion, and at the same time, it will have a certain impact on ventilation, ventilation and light, so if you want to prevent the phenomenon of overgrowth, you must move scissors to the rose in autumn. The purpose of pruning is to cut off excess side branches, including withered branches, diseased branches, overgrown branches and so on. After pruning, it can promote the nutrient uptake of the remaining branches and increase the air permeability, so the probability of flowering is greatly improved.

2. Lack of light

If the rose wants to blossom, a certain amount of light is essential, because only when exposed to the sun can normal photosynthesis be carried out. Of course, we also know that many friends are afraid of being sunburned by the sun. In fact, there are two solutions. One is to set up a sunshade net at home and protect plants through the sunshade net during the most sunny period. The other is to choose to bask the rose in the early morning or evening, which can also avoid the growth of bacteria caused by high temperature.

Third, note:

1. Rose growth is best placed in a ventilated place to avoid bacterial breeding. You can choose to set up a ventilator in the greenhouse or blow it directly with a fan.

2. In addition to nitrogen fertilizer, phosphorus and potassium fertilizer can also be added appropriately during the flowering period of the rose, of course, all fertilizers need to be diluted and then applied.

Prevention of diseases and insect pests, spring and autumn rainy season, leaves are prone to black spot and powdery mildew. After discovery, it can be treated with 1000 times liquid spray of 70% wettable topjin powder, or cotton can be dipped in alcohol to wipe the positive and negative sides of flowers and leaves and petioles. The main pests are aphids and red spiders, which can be sprayed 1500 times with 40% dimethoate EC.
