In autumn, the temperature is getting lower and lower, so flowers should be handled flexibly. For example, Aglaia odorata and Lucky Bamboo have poor cold resistance, and they should be moved in when the temperature is lower than 10 ℃; Clivia and Wenzhu should be moved in at 5 ℃; camellia and azalea should be moved in at 0 ℃.
Autumn is the second vigorous growth season for most flowers, so water and fertilizer should be enough, but after the late autumn, the weather will gradually turn cool, so it is necessary to reduce the supply of water and fertilizer, apply appropriate P and K fertilizer, and improve the cold resistance of plants.
The pruning in autumn should be determined according to the state of the plant. For example, the rose that failed in late summer and the hydrangea before September should be pruned 0.5cm above the full shoot point of the branch. The osmanthus and chrysanthemum that will bloom in autumn should be pruned after the flowers.
To raise flowers in winter, you need to keep warm and warm in the sun. There are two tricks for Huahua. One is to insert a wooden strip at the edge of the pot, put on a plastic bag and set up a warm shed. The other is to find a large flowerpot, put the plants in it, and put sawdust and pine needles between the flowerpots.
In winter, the temperature is low, and the watering time must be around noon, and the tap water should be dried two days in advance; in fertilization, except for autumn grass flowers, other plants should control the fertilizer and water, and dormant plants should stop fertilization.
In the area of indoor heating in winter, the above two points do not need to be considered, but the indoor air is dry. For some wet flowers, it is necessary to frequently spray water or cover a bag to keep wet. At the same time, it is necessary to pay attention to more ventilation, so as not to make the flowers stuffy.
The temperature in spring is getting higher and higher, but the climate is changeable. For example, the most annoying cold in the late spring, so the flowers in the winter must leave the room late. The flowers in the south of the Yellow River will leave the room after the Qingming Festival, and the flowers in the North of the Yellow River will leave the room after the rain.
Don't worry too much about the water and fertilizer management in spring, especially for the newly developed plants, the water demand is not large, and it's easy to clog the roots with too much water; if the fertilizer is applied, the concentration should be light, otherwise the new roots can't bear it and it's easy to burn the seedlings.
Early spring pruning is the most important part of the year, but there are also different pruning methods for different types of flowers, such as rose and Fusang that bloom on annual branches, azalea and gardenia that bloom on biennial branches.
In spring, everything revives, and it is also a high incidence period of flower diseases and insect pests. The experience of flower prevention is greater than treatment, so it is necessary to spray the flower with multi fungus spirit and flower protector once a half month.
The biggest problem of flower cultivation in summer is that the light is too strong and the temperature is too high, especially in the hot noon, we must put on the sunshade to protect ourselves from the sun and cool down. In addition, in the exposed southern area, we should also put on the canopy in the rainy season.
In summer, the temperature is high, the water evaporation is fast, and the frequency of watering should be higher than that in spring, and it's better to water in the morning and evening every day; if fertilization is applied, it must be thin fertilizer frequently, otherwise the temperature is too high, it is easy to cause the occurrence of plant fertilizer damage.
