1、 How many times a year

Dahlia is a perennial herb, so it will bloom every year. The number of flowers in a year depends on the breeding quality. If it is well bred, it will bloom about three times a year. In addition to the dormancy period, it can bloom all year round. If it is not well bred, it will bloom only once a year, and the flowering period is short

2、 How to breed

When breeding it, we should first choose the appropriate soil. The soil with high air permeability and humidity and fertile soil is the first choice; It is a plant that likes half shade. It needs light at all times except when the sun is particularly large; For its demand for water, the soil does not need watering if it is not dry. Excessive watering will cause root rot; If it is a seed bearing variety, collect seeds after each flower withering and seed bearing to prepare for the next planting

3、 Precautions

1. Don't water too often. Don't let the basin soil have ponding. Especially in rainy days, pour out the ponding in the basin. If the soil has been wet and caked, you need to change the soil

2. Its root system is sensitive and delicate. Remember not to apply thick fertilizer, which will burn its root system. In this case, it can be difficult to deal with, so try to apply thin fertilizer, such as rotten fertilizer

3. For dahlias with poor growth, the flower centers should be removed in their infancy to stimulate their growth. By July and August, they should be pruned, and good quality flowers will grow after a month
