Dahlia cutting and branching, no problem in operation

Dahlias are not only beautiful, but also have a long flowering period. They can bloom in spring and autumn. Once they bloom, they will last for a month or two. Enchanted flower friends, in addition to going to the flower market to buy, can also follow the flowers, learn cutting and branching

Cutting:

1. Cut off the current year's Dahlia branches, each 8-15 cm long, with a pair of leaves for necessary photosynthesis

2. The stem of dahlia is relatively brittle. It's best to use wet sandy soil for cutting (pour wet sandy soil before cutting). First insert a hole with scissors and insert the flower branches into a depth of 2-3cm

3. After cutting, it must be placed in the shade, not exposed to the sun, and sprayed wet every 1-2 days. About 1 week, the flower branches will be tall and straight, indicating that they are already taking root and can be properly placed in a position with slightly better light

4. After cutting for 15-20 days, it can be planted or transplanted to the flower pot. Be careful not to hurt the root system. The sand and soil on the root need not be removed. It can be directly buried in the new pot soil, pressed, watered and placed in a cool clothes basin. It can be maintained normally after a week

Ramet:

1. Now it can be divided into plants. The roots of Dahlia are like sweet potatoes. After flowering, control the water first, trim and cut off the branches, dig out the roots, and tear up several small "sweet potatoes"

2. After tearing off, put all the roots together in a ventilated place to dry. After 2-3 days, bury them in a dry sand pile. Cover them with plastic film or straw in winter to facilitate winter. Flower friends in the north can raise them

3. Next spring, we can dig out the buried roots and plant them again

If you have a seedling, you don't worry about growing. The flowers bloom bigger than the pot

1. Soil

We have a long history of growing dahlias. They are very easy to grow. Ordinary garden soil mixed with some sand is very good, or rotten leaf soil. In short, soil with good drainage and ventilation is OK

2. Lighting and watering

Dahlia likes the astigmatism environment. The location is better in light, but it can't be exposed to the sun. Keep more than 6 hours of bright light every day, which is conducive to flowering. You don't need to water too much. If you see dry and wet, you can pour it through

3. Fertilization

Dahlia can bloom in spring and autumn. Remember to add some fertilizer before and after the flowering period. It can bloom more and bigger. You can add chicken manure, nitrogen and phosphorus fertilizer, nutrient solution and so on. You can also pour retted rice washing water and bean dregs water. Once every summer and winter
