How to grow potted dahlias

Dahlia is generally as high as the plant shape, the stem is also very strong, more importantly, its flowers are large and colorful, which is very suitable for garden planting. But there are also friends who like to plant it as a family pot, as long as the maintenance and management is proper, it can also bloom a beautiful flower as scheduled. So, how to grow potted dahlias?

Dahlia is a very strong ornamental flowering plant, and has a strong ability to adapt to the environment, suitable for planting in most areas of our country, and has a strong effect of landscaping and beautification. Although the Dahlia blossoms are very large and gorgeous, it does not have a high demand for soil. As long as it is loose, breathable and deep slightly acidic sandy soil, it can often be fed.

However, the planting time of dahlias is better in spring, and a strong underground rhizome is generally dug out of the soil and planted. When the plant grows to a height of about 40-50 cm, it is recommended to build a support frame around the plant. Because Dahlia branches grow tall, their own weight is relatively large, so it is easy to lodge.

Dahlia has powerful underground tubers, the original generally grow many and large, and strong tubers can store a wealth of water, so this plant is more drought-tolerant. Once there is a lack of water and drought, the plant can transport the water stored in the underground tuber to the branches and leaves, thus ensuring that the growth of the plant will not be greatly affected. But dahlias are not water-resistant and avoid waterlogging, otherwise it is easy to cause tubers to rot.

But even if dahlia is more drought-tolerant, we should not let it be in a state of water shortage for a long time, otherwise it will affect its growth and flowering. After all, Dahlia has luxuriant branches and leaves, large and colorful flowers, and consumes more water. Although its underground tubers can also store a lot of water, but after all, the capacity is limited, so it should be watered in time when suffering from drought.

Dahlia generally wait until the basin soil dries and then water thoroughly, watering master the principle of "do not dry or dry or water thoroughly", so that it is better to "see dry and wet". And fertilization is also quite fastidious, after all, it has many flowers and leaves, not only consumes a lot of water, but also consumes more nutrients. Therefore, we should fertilize it in time to avoid weakening its growth and affecting flowering.

The fertilization of Dahlia generally adopts the principle of "thin fertilizer and frequent application", which can be applied every half a month during the growing period, and it is appropriate to use rotten organic fertilizer. And in order to promote flowering, proper topdressing is also needed before flowering. But at this time is mainly to promote flowering, so it is necessary to topdressing phosphorus and potassium fertilizer, appropriately increase the amount to ensure that the plant grows luxuriantly, colorful flowers, but also can prolong the flowering time, so as to be more ornamental.
