Cultivation methods and precautions of false forsythia

Cultivation method of false forsythia

Temperature and light

Forsythia suspensa prefers a warm growing environment and is not cold-resistant. The suitable temperature for its growth is between 18℃ and 26℃. When the temperature drops below 5℃ in winter, it is easy to suffer frost damage, and the temperature must be above 5℃ to survive the winter safely.

Forsythia suspensa likes light and is relatively shade-tolerant. During its growth period, it should be given sufficient light so that it can grow well. Some of the variegated varieties need more exposure to sunlight to achieve bright and beautiful colors. If there is insufficient light, the colors will fade and the ornamental value will be reduced.

Watering and fertilizing

Forsythia suspensa likes moisture and is not drought-resistant. During the growth period, it is necessary to maintain sufficient water supply to meet the growth needs of the plant. Be careful not to have water accumulation in the pot, especially pay attention to drainage during the rainy season. In winter, keep the soil in the pot dry and water sparingly.

Forsythia suspensa needs to consume a lot of nutrients during its growth period, and a lot of nutrients are needed for flowering and fruiting, so it needs to be fertilized frequently. During the growth period, nitrogen-based fertilizers should be applied once every half a month to promote plant growth; some phosphorus fertilizers and potassium fertilizers need to be applied before flowering to promote flowering; applying phosphorus fertilizers and potassium fertilizers after flowering can increase the ornamental value of the fruit and prolong the fruit viewing time.

Precautions for the cultivation of false forsythia

prune

Forsythia suspensa is relatively resistant to pruning. Frequent pruning is beneficial to the ventilation and light transmission of the plants and the shaping of the plant shape. When pruning, you can combine it with repotting in spring. You should cut off some weak and diseased branches of the false forsythia to promote its better growth. After the false forsythia blooms, if you need to keep the fruit, do not prune it. If you do not need to keep the fruit, you can cut off the inflorescence so that it can branch and bloom again.
