Cultivation methods of spring flowers in dance
1, lighting
Salvia blooms vigorously in sunny environment, but it is not resistant to strong light. In spring and autumn, you need to provide about 4-6 hours of sunshine every day. In summer, you should block the noon sun and get a little sun in the morning and evening.
2. Temperature
Salvia miltiorrhiza Bunge is resistant to heat and cold, and can be cultivated all over the country all year round. However, potted plants have poor cold tolerance, so they should be moved back to a warm home for protection as soon as possible. As for usual, 15-30 degrees Celsius is the best maintenance temperature.
Step 3 apply fertilizer
There are many flowers, the flowering period is long, and more nutrition is needed. Apply a small amount of dilute phosphorus and potassium fertilizer once a month at flowering stage, and apply compound fertilizer mainly containing nitrogen fertilizer 2-3 times after flowering.
water
Spring flowers are intolerant of waterlogging. Usually, water them until the soil is dry, and then water them. Follow this principle. When the soil is dry and wet, water it thoroughly and keep the soil moist. When the weather is dry in summer, spray some water on the leaves of plants at noon.
Matters needing attention in Wu Chunhua maintenance
1, pruning branches and leaves: Salvia miltiorrhiza Bunge is a very pruning-resistant plant with strong vitality and rapid growth. If it wants to blossom more and divide more plants, it needs to be pruned, especially after flowering, it is necessary to cut off the residual flowers, dead leaves, weak branches and over-dense branches together, which can not only keep the appearance beautiful, but also reduce the consumption of nutrients.
2. Pest control: Dan Chunhua is prone to pests such as white mold and aphids. When white mold occurs, chlorothalonil diluted by 600-800 times can be sprayed, and when aphid pests occur, dichlorvos diluted by 1000 times can be used to kill insects.
