Dahlia flowers are very beautiful, but if you want to grow dahlias, you should be careful not to let them get cold, not hot, not too dense, and not spoiled. How do you grow dahlias? Let's look at the five taboos of dahlia care.

One: avoid waterlogging

The dahlia's root is a thick, juicy fleshy root that needs oxygen, so the soil must be loose and breathable, with good drainage. If the soil is compacted and oxygen in the water is lacking, it can easily lead to root rot, or even death.

However, dahlia leaves are large, and transpiration consumes a lot of water. It needs a certain amount of water. If the leaves wilt due to high temperature and dryness, water should be sprayed immediately, in one pass, avoiding overwatering to prevent waterlogging; p>

After rain, dahlia leaves may wilt, mainly because the soil is too wet, the root hairs are damaged, water cannot be absorbed, and leaf transpiration loses water, but at this time, do not water immediately; you can do it several times. Spray water on the leaves. After the soil dries slightly and new roots grow and the absorption function recovers, you can water normally.

Two: avoid shade

Dahlias are light-loving and cannot tolerate shade. In an environment with insufficient light and moisture, the root system will become thinner, absorption capacity will decrease, leaf photosynthesis will weaken, flower buds will not develop fully, the flowers will be dull, and it will be difficult to bloom.

If Jinan lacks light, the plants will become weak and easily die. Therefore, during cultivation, the environment must ensure enough for normal growth and development, and for blooming beautiful flowers.

In a humid environment with insufficient light, the root system is weak, absorption decreases, leaf photosynthesis is poor, flower buds develop poorly, the flowers are dull, and it may even be difficult to bloom. If severe light deficiency lasts a long time, the plants will become spindly and eventually die. Therefore, the cultivation environment for dahlias should remain sunny so they can grow normally and produce beautiful flowers.

Three: avoid over-thickening

The dahlia's roots are strong and vigorous, and its branches and leaves are large and big, so it needs a lot of fertilizer. In addition to the amount of base fertilizer applied, topdressing is also needed at the right time. Topdressing should use light fertilizer, avoiding heavy fertilizer, to prevent root burn and dead branches.

Four: avoid heat

Dahlias like warmth and coolness, and avoid high temperatures and heat; the suitable growth temperature is 20 to 25°C. Therefore, dahlias grow well in late spring, early summer, late autumn, and early winter. However, from July to August, the temperature rises, growth slows, and blooming is poor or stops. Therefore, dahlias should be watered carefully in summer to ensure healthy growth of the seedlings.

Five: avoid too many flowers

Too many dahlia flowers can lead to poor flower quality and a short flowering period. Therefore, it is necessary to properly control the flowers. So, starting from shaping, you must pinch the heart and promote branching. As the branches grow, the small buds are constantly removed, leaving only the top bud and promoting branch growth. After budding, in addition to short branches, one strong branch is also kept. In addition to the flower buds, it is better to cut off the extra buds to ensure the flowers bloom large and gorgeous.
