The four-season watering of courtyard flowers

There are many kinds of flowers in the courtyard, and the requirements for water are different due to the differences in environmental conditions of the place of origin. Suitable soil moisture is an important guarantee for the growth of flowers and trees. Generally speaking, the soil moisture content is 60% to 70%. More than 80% of the soil air content is low, root respiration is inhibited, and flower growth will be affected. However, for flowers with strong drought resistance, such as Phoenix tail orchid, dragon fruit, azure, golden locust and so on, if there is too much water content in the soil, it will affect the growth and development of the root system.

Courtyard flowers

How to judge the watering time: when the leaves are sagging, it is the most obvious sign of water shortage, so it is necessary to replenish water in time. The wilting and drooping of leaves will weaken its growth, which is not conducive to the normal growth of the plant. The flowers must be hydrated in a timely and moderate manner before the leaves droop. To know exactly whether flowers need watering, insert a bamboo pole into the soil and stay for 1 minute before pulling it out. If the bamboo pole is stained with soil or invisible water stains, there is no need to water; if the bamboo pole is not stained with soil or water stains are not visible, it needs watering.

There are many kinds of flowers in the courtyard, coupled with the difference in tree age, their geographical location and orientation are different, and their water requirements are also different. According to the change of season. A brief description is as follows:

Watering flowers in spring: although the temperature gradually rises, there is often an unstable phenomenon of ups and downs. It should be based on the change of temperature. Replenish water properly. Normally growing trees, shrubs and ground-planted bulb flowers generally do not need special watering, unless there is no rain for a long time, and when they are sprouting new buds or budding, they can be watered properly, which is beneficial to the growth and flowering of new leaves. For newly planted trees and shrubs, in order to ensure survival, timely watering is needed to keep the soil moist. But the soil must not be too wet, as long as the soil is slightly dry, it should be watered. But the watering temperature can not be too different from the soil temperature, too high or too low, it will cause damage to the roots.

Summer watering: when the temperature rises, the water demand of courtyard flowers increases accordingly, so it is necessary to prevent the leaves from being short of water and withering. Early summer is in the rainy season, there is plenty of rainfall, woody flowers generally do not need watering. Be careful not to let the soil accumulate water and drain it in time. In the midsummer, if the continuous high temperature weather, water evaporation is large, for some trees and shrubs that are not resistant to drought and high temperature, pay attention to irrigation supplement and spray water to the leaves sooner or later to ensure that the leaves are fresh and straight. Herbaceous flowers, the soil still needs to be kept moist, some bulb flowers leaves have withered into the dormant period, do not need watering, can be kept dry.

Autumn watering: the temperature began to drop, the daily temperature difference gradually increased, Rain Water decreased obviously, and the number of sunny days increased. In early autumn, the temperature is sometimes still high and the air is dry. For most courtyard flowers, they are in the second stage of rapid growth, and the soil must be kept moist. Can properly spray water to the leaves, do not spray water to the flowers and hairy leaves, maintain a high air humidity, which is very beneficial to the growth of flowers and trees.

Winter watering: there is an obvious change in outdoor temperature. In early winter, in the north, the temperature has dropped to about 0 degrees, and frosts will occur in the Yangtze River basin. Most courtyard flowers basically stop growing, and some of the flowers planted on the ground are taking root. At this time, watering is usually stopped to prevent the soil from getting too wet and causing the roots to rot. Entering the cold winter, Rain Water decreased and the amount of snow increased. At this time, it is not a problem for the soil to be wet. But avoid breaking branches caused by snow.
