Five taboos in the cultivation and maintenance of Dahlia (Dahlia)

Dahlia (dahlia) for perennial herbaceous flowers, capitate, flowers big pretty, to plant dahlia, pay attention to "five taboo."

- Avoid waterlogging

Dahlia root system is thick and juicy fleshy root, strong aerobic, requiring loose and breathable, good drainage soil environment, if the soil hardening, waterlogging hypoxia, easy to cause rotten roots, or even death. However, Dahlia leaves have many flowers and large transpiration water consumption, which requires-fixed water. If high temperature and dryness cause wilting of leaves, they should be watered immediately, subject to-second watering, and excessive watering should be avoided to prevent waterlogging; If it is sunny after rain, wilting of leaves occurs, mainly due to damaged root hairs and inability to absorb water, coupled with transpiration loss of leaves. At this time, watering cannot be carried out immediately, but multiple foliar spraying can be carried out. After the soil is slightly dry, new roots are formed and the absorption function is restored, normal water management is carried out. At ordinary times, the principle of keeping the soil moist is adopted.

Avoid shadow

Dahlias love light, not shade. In the dark and humid environment with insufficient light, the root system is weak, the absorption rate decreases, the photosynthesis of leaves is low, the flower buds are poorly developed, the flowers are small and dark, and even it is difficult to bloom. If severe light deficiency lasts for a long time, the plant becomes weak and eventually dies. Therefore, Dahlia cultivation environment to maintain sufficient sunlight, only to normal growth and development, blooming gorgeous flowers.

Third, avoid thick fertilizer

Dahlia root fat, branches and leaves more and larger, need fertilizer. On the basis of preparing high-quality nutrient soil and applying enough organic fertilizer, topdressing should be applied lightly and frequently, and thick fertilizer should be avoided to prevent burning roots and causing dead branches and seedlings.

Avoid waterlogging

Dahlia root system is thick and succulent fleshy root, strong aerobic, loose ventilation, good drainage soil environment, if the soil hardening, waterlogging hypoxia, easy to cause rotten roots, or even death. However, Dahlia leaves have many flowers and large transpiration water consumption, which requires a certain amount of water. If high temperature and dryness cause wilting of leaves, they should be watered immediately, subject to one-time watering, and excessive watering should be avoided to prevent waterlogging; If it is sunny after rain, wilting of leaves occurs, mainly due to damaged root hairs and inability to absorb water, coupled with transpiration loss of leaves. At this time, watering cannot be carried out immediately, but multiple foliar spraying can be carried out. After the soil is slightly dry, new roots are formed and the absorption function is restored, normal water management is carried out. At ordinary times, the principle of keeping the soil moist is adopted.

Second, avoid shade

Dahlias love light, not shade. In the dark and humid environment with insufficient light, the root system is weak, the absorption capacity is reduced, the photosynthesis of leaves is low, the flower buds are poorly developed, the flowers are small and dark, and even it is difficult to bloom. If severe light deficiency lasts for a long time, the plant becomes weak and eventually dies. Therefore, Dahlia cultivation environment to maintain sufficient sunlight, in order to normal growth and development, blooming gorgeous flowers.

Three taboo thick fertilizer

Dahlia root fat, branches and leaves more and larger, need fertilizer. On the basis of preparing high-quality nutrient soil and applying enough organic fertilizer, topdressing should be applied lightly and frequently, and thick fertilizer should be avoided to prevent burning roots and causing dead branches and seedlings.

4 Avoid heat

Dahlias love warm, cool, avoid heat and high temperatures. Suitable growth temperatures range from 20 to 25 ° C. Therefore, dahlia in late spring, early summer and late autumn, early winter season, good growth and development. July to August high temperature heat, slow growth, poor flowering or stop flowering, so dahlia in the hot summer season, pay attention to water supply seedlings. After the flower withers, the residual flowers and branches should be cut off in time, but they should not be cut dry immediately. After the heat in September, 2 to 3 nodes are left at the base of the old stem to promote the germination of autumn buds, so that large and bright autumn flowers can be opened after the end of October.

Five taboos and many flowers

Dahlia flowers too many large flowers will lead to poor flower quality, short flowering period, therefore, to appropriate control flowers. Start with seedling shaping. When planting survival seedlings about 10 cm high, leave 3 to 5 leaves to pick the heart, promote branching. During the branching growth period, axillary buds are continuously removed, only terminal buds are retained, and branches are promoted to be robust. After budding, in addition to retaining a strong bud at the top of the branch, the excess buds should be thinned out to ensure that the flowers are large and magnificent.

The above is all I know about dahlia today, I hope that flower friends will be helpful after reading this article, if you want to know more about dahlia related knowledge, please continue to pay attention to the fleshy garden, we will provide you with more relevant knowledge!

Dahlia cultivation and maintenance process of five taboos Dahlia is a perennial herbaceous flowers, head, flowers big pretty, to plant a good dahlia, pay attention to "five taboos." A bogey waterlogging dahlia root system for thick and juicy fleshy roots, strong aerobic, loose ventilation, good drainage of the soil environment, if the soil hardening, waterlogging hypoxia, easy to cause rotten roots, or even death. However, Dahlia leaves have many flowers and large transpiration water consumption, which requires a certain amount of water. If high temperature and dryness cause wilting of leaves, they should be watered immediately, subject to one-time watering, and excessive watering should be avoided to prevent waterlogging; If it is sunny after rain, wilting of leaves occurs, mainly due to damaged root hairs and inability to absorb water, coupled with transpiration loss of leaves. At this time, watering cannot be carried out immediately, but multiple foliar spraying can be carried out. After the soil is slightly dry, new roots are formed and the absorption function is restored, normal water management is carried out. At ordinary times, the principle of keeping the soil moist is adopted. Two bogey shade dahlia love light, intolerance shade. Under the overcast and humid environment with insufficient light, the root system is weak, the absorption capacity decreases, the leaf photosynthesis is low, the flower bud development is poor, the flower color is small and dark, and even it is difficult to bloom. If severe light deficiency lasts for a long time, the plant becomes weak and eventually dies. Therefore, Dahlia cultivation environment to maintain sufficient sunlight, in order to normal growth and development, blooming gorgeous flowers. Three bogeys thick fertilizer dahlia root fat strong, branches and leaves more and larger, need fertilizer. On the basis of preparing high-quality nutrient soil and applying enough organic fertilizer, topdressing should be applied lightly and frequently, and thick fertilizer should be avoided to prevent burning roots and causing dead branches and seedlings. Four bogey heat dahlia hi warm, cool, bogey heat high temperature. Suitable growth temperatures range from 20 to 25 ° C. Therefore, dahlia in late spring, early summer and late autumn, early winter season, good growth and development. July to August high temperature heat, slow growth, poor flowering or stop flowering, so dahlia in the hot summer season, pay attention to water supply seedlings. After the flower withers, the residual flowers and branches should be cut off in time, but they should not be cut dry immediately. After the heat in September, 2 to 3 nodes are left at the base of the old stem to promote the germination of autumn buds, so that large and bright autumn flowers can be opened after the end of October. Five bogey flowers how much beautiful flowers too many flowers will lead to poor flower quality, short flowering period, therefore, to properly control flowers. Start with seedling shaping. When planting survival seedlings about 10 cm high, leave 3 to 5 leaves to pick the heart, promote branching. During the branching growth period, axillary buds are continuously removed, only terminal buds are retained, and branches are promoted to be robust. After budding, in addition to retaining a strong bud at the top of the branch, the excess buds should be thinned out to ensure that the flowers are large and magnificent.
