The most beautiful moment of dahlias of all varieties

It's called sweet potato flower in my hometown. It has a variety of colors. The varieties alone have exceeded 30000, and the diameter can exceed 30cm. It's not inferior to peony at all, so it's also called Tianzhu peony. Let's enjoy the beautiful dahlias

According to Huahua, dahlia can be said to be a must for lazy people to raise flowers, because it can grow well without much care, but if you want flowers to bloom, you should pay attention to the following points

Maintenance skills of Dahlia

Soil: loose and fertile humus or sandy soil with good drainage is most suitable for the growth of Dahlia. Vegetable garden soil, rotten leaf soil and sandy soil can also be mixed and prepared in the proportion of 5:3:2

Water: the amount of water will affect the height of the plant. During the seedling raising period, pay attention to water control to prevent excessive growth of branches and leaves; When watering, the basin soil shall be damp but not wet according to the principle of dry and thorough watering. Spray can be humidified around the flowerpot in summer after high temperature. p>

Light: if Dahlia wants to blossom more, it's best to keep more than 6 hours of light every day. In summer, when the light is strong, it needs appropriate shade to avoid burning leaves and affecting flowering

Fertilization: Dahlia likes fertilization. It is generally applied with diluted rotten liquid fertilizer or compound fertilizer. Topdressing is carried out every 10 days in spring and autumn growing season. Fertilization is not applied in high-temperature weather in summer

How does Dahlia semi dormant in summer do

Dahlia will enter a semi dormant state in summer. To survive the summer safely, we must pay attention to the following points:

1. Root system maintenance: Dahlia has large fleshy roots. It should avoid dampness and fear heat in summer. It is easy to rot in high temperature weather, so it should be dry and wet when watering, loose soil and breathable. After heavy rain, the ponding in the basin should be cleaned in time

After discovering rotten roots, immediately cut off the broken roots, change pots and soil, or "amputate" cuttings for reproduction

2. Shading and maintenance: avoid direct sunlight in summer. Outdoor cultivation is most likely to be sunny after rain. Pull a shading net in time for protection

3. Pruning and maintenance: Dahlia likes to be cool and is afraid of being stuffy. In summer, when the branches and leaves are too dense and in full bloom, prune the sparse branches, and retain 3 ~ 4 sections of side branches; After flowering, prune the flowering branches and dead branches, and cut the main stem to 15 ~ 25cm

4, disease and insect protection: Summer dahlia is most susceptible to Botrytis cinerea and powdery mildew, floral browning, irregular shape, long speckle on leaf edge, dry and softening. When these phenomena occur, we should promptly eliminate and destroy the disease branches and spray with 50% carbendazim WP 500 times. p>
