How to protect flowers and trees from harm

Newly bought potted plants can easily wither and die if they are not treated, high temperatures in summer can easily cause plants to evaporate too much water and die, and typhoons will cause great harm to plants. today, let's learn how to protect our flowers and trees from these three aspects.

I. Culture methods of newly purchased potted plants

1. Understand and master habits: when you buy a potted plant, you'd better know its name, in order to inquire about its growth habits, living environment, origin and climate, key points of management, cultivation techniques, prevention of diseases and insect pests, and so on. Query these in order to make it better adapt to the new environment. This information can be found on the Internet or in bookstores.

two。 Watering principle: for newly bought potted plants, enthusiasm, freshness are very strong, look at it later, water it, water it has a principle: after the pot soil is dry, and then water thoroughly, that is to say, use your hands to dig the soil in the flowerpot, the soil is loose, this is after the pot soil is dry; watering is to slowly pour water into the flowerpot and let the water slowly seep down until a lot of water flows out of the leak, which is considered to be thoroughly watered. If you can't water a little every day, the roots may rot if you water it every day.

3. Change the soil and change the pot: everyone likes to change the pot and change the soil for the newly bought potted plant. This is not recommended. The reason: change a new growth environment and change the soil environment for it. The plants with strong adaptability are all right. What if they are not strong? It's easy to get sick and die. If you change the soil, it depends on the adaptability of this plant.

II. Key points for flower cultivation in summer

Illumination: when growing flowers in summer, we must be careful not to let the flowers be exposed to the sun. Especially plants from the south. Some friends think that the sun is good in summer and let the flowers be exposed in the sun. in fact, it is not good to do so. Due to regional differences, the air in the north is drier than that in the south, and the sun will be stronger than that in the south. Direct sunlight can easily damage the flowers. It is best to move all the flowers back home and put them on the windowsill, cover the curtains and let the sun shine again, so that the flowers will not be damaged by the sun.

Watering: ping an tree, green pineapple and other fern root plants relatively like water, but can not be watered too much, usually once every two or three days. On the other hand, immortal plants are watered once a week or half a month, because they are in the peak growing season in summer, so they can be cultured outdoors.

Diseases and insect pests: summer flower cultivation should also pay attention to the prevention of insect pests, should regularly spray pesticides for soil sterilization, once a month is appropriate.

Third, how do greening plants protect against typhoon

Family green plant pot: the biggest hidden danger in the typhoon is some green plant potted plants raised on the balcony of residents. Faced with the arrival of the typhoon, everyone is busy stocking grain and other Taiwan prevention measures, often ignoring these small potted plants that usually do not pay attention to, but it has become a major hidden danger in the typhoon. Therefore, before the occurrence of the typhoon, we should not only do a good job of Taiwan prevention measures, but also prepare for the green potted plants on the balcony.

Street trees: before the typhoon, the relevant departments should prune the green trees on both sides of the urban trunk roads and neighborhood roads to avoid falling branches on passers-by and vehicles caused by the typhoon. And straighten the inclined trees to be strengthened, eliminate the hidden dangers of safety, and move the pruned branches away in time, so as not to cause unnecessary impact on pedestrians.

Nursery seedlings: timely drainage, lower water level, especially the seriously flooded nursery should make the ridge surface of the nursery open as soon as possible to ensure the respiration of seedling leaves and roots. When the soil water content is suitable, the soil around the seedling should be ploughed and loosened in time to increase the air permeability of the root and effectively restore the tree potential. Correct the crooked and lodging seedlings in time, and strengthen the cultivation and steadiness of the roots for the seedlings with weak roots. For the seedlings with serious root injury, the way of crown leaf cutting and branch thinning is adopted to reduce leaf transpiration and prevent death.

In addition to the three technologies listed above, flower planting technology also includes a lot of, including water and fertilizer, light, soil and so on, all have technical requirements, we should continue to learn and make progress in the process of growing flowers.
