Green flowers, five taboos on how to raise dahlias well

Dahlias are beautiful, but if you want to plant dahlias, you should be careful not to be cold, hot, thick and spoiled. How to raise dahlias? Let's take a look at the five taboos maintained by Dahlia.

One to avoid waterlogging

The root of Dahlia is a thick and succulent fleshy root, which is aerobic, so the soil must be loose and breathable, and the drainage is good. If the soil is compacted and the water is deprived of oxygen, it can easily lead to rotten roots and even death.

However, the leaves of dahlias are very large, and transpiration consumes a lot of water. It needs a certain amount of water. If the leaves wilt due to high temperature drying, spray water immediately and pass at once to avoid overwatering to prevent waterlogging; p >

Dahlia leaves may wither after rain, mainly because the soil is too wet, root hair damage, water can not be absorbed, leaf transpiration and loss of water, but at this time, do not immediately water, you can do it many times. Leaves are sprayed with water. After the soil is slightly dry, new roots grow, the absorption function is restored, and the water can be watered normally.

Two taboos

Dahlias are light and have no shadow. In an environment with insufficient light and humidity, the root system will become thinner, the absorption capacity will be reduced, the photosynthesis of the leaves will be weakened, the buds will not fully develop, and the flowers will darken, making it difficult to blossom.

If Jinan lacks light, the plants will become weak and die easily. Therefore, in the process of planting, the environment must ensure that enough eyes grow and develop normally and bloom beautiful flowers.

In the moist environment with insufficient light, the root system is weak, the absorption is reduced, the photosynthesis of leaves is poor, the development of buds is poor, the flowers are dark and even difficult to bloom. If there is a severe lack of light for a long time, the plant will become slim and eventually die. Therefore, the cultivation environment of dahlias should be sunny enough in order to grow normally and develop beautiful flowers.

Three taboo thickeners

Dahlias have strong roots, large branches and leaves, and need a lot of fertilizer. In addition to the amount of base fertilizer applied, topdressing is needed at the right time. Light fertilizer should be used in topdressing, and heavy fertilizer should be avoided to prevent root burns and withered branches.

Four bogey calories

Dahlias are warm and cool, avoiding high temperature and high temperature, and the suitable growth temperature is 20 to 25 °C. Therefore, dahlias can grow well in late spring, early summer, late autumn and early winter. However, from July to August, the temperature rises, the stretching is slow, the flowering is poor or the flowering stops. Therefore, dahlias should pay attention to summer water supply to ensure the healthy growth of seedlings.

Five taboos and too many flowers

Too many dahlias will lead to poor quality and short flowering period. Therefore, it is necessary to control flowers properly. Therefore, starting with plastic surgery, it is necessary to pick the heart and promote branches. As the branches grow, the buds are constantly erased, leaving only the terminal buds and promoting the branches. After the bud, in addition to the short branch, but also retained a strong branch. In addition to the buds, it is better to cut off the extra buds to ensure that the flowers bloom when they are large and gorgeous.
