Cultivation methods and precautions of false forsythia

The vitality and adaptability of the false forsythia are very strong, and it is very easy to grow. Although the false forsythia likes light, it is also shade-tolerant to a certain extent. At the same time, it is also resistant to drought and barrenness, and is not picky about soil. It can grow normally in neutral, slightly acidic and alkaline soils. The false forsythia has amazing cold resistance and can withstand temperatures as low as minus 50 degrees Celsius, so the false forsythia can become a leader in northern landscaping.

Cultivation method of false forsythia

When growing false forsythia, you can choose a flower pot with good air permeability and drainage performance, and prepare a culture soil with good drainage, rich in humus, loose and fertile. Provide appropriate shade when the light is strong. When the indoor light is weak, regularly release it outdoors to receive light. Try to control the temperature between 18 and 26°C, and not lower than 5°C. Watering should follow the principle of "watering when the soil is dry and watering when wet". Apply fertilizer in small amounts and multiple times, and apply thin fertilizer frequently. Apply it to the soil near the roots. Pay attention to preventing diseases and pests and change the soil every 1 to 2 years.

1. Potting soil

For growing false forsythia, you can choose a tile or clay pot with good air permeability and drainage performance. As for the soil, it grows well in sandy loam that is well-drained, rich in humus, loose and fertile. You can mix humus, river sand, garden soil and base fertilizer to make the culture soil. Before filling the soil, cover the bottom of the pot with a layer of broken tiles to facilitate drainage.

2. Lighting

Forsythia suspensa likes sunlight and can tolerate partial shade, but should avoid direct sunlight. In summer, the direct sunlight is strong. To avoid the strong light burning the plant and causing the plant to wilt and the leaves to turn yellow, you can use a shade cloth to build a small shed to provide shade when the sunlight is strong at noon, or directly place it in a well-lit place indoors for cultivation. In spring and winter, the indoor light is weak, and it needs to be regularly released outdoors to receive light when it is warm at noon to avoid poor plant growth.

3. Temperature

Forsythia suspensa has poor cold resistance, and the most suitable growth temperature is 18 to 26℃. It is prone to frost damage when the temperature is below 5℃. Therefore, Forsythia suspensa grows well in spring and autumn, but grows slowly when the temperature is too high in summer and too low in winter. When the temperature is high in summer, it can be placed in a cool place indoors. When it is cold in winter, the plant should be placed in a warm place indoors to avoid frost damage from low temperature.

4. Moisture

   Forsythia suspensa is not cold-resistant and should avoid waterlogging. Watering should follow the principle of "water when dry and water when wet". Water when the soil surface is slightly dry and white, and stop watering when the water flows out from the bottom of the pot. Do not water excessively to the point of water accumulation in the pot to prevent the roots from being immersed in water for a long time and rotting. During the growing period, the plant grows vigorously and consumes a lot of water, so watering needs to be increased to keep the soil moist.

5. Fertilization

Fertilization for Forsythia suspensa should be done in small amounts and multiple times, with thin fertilizers applied frequently. Do not apply too concentrated fertilizers at one time to avoid fertilizer damage to the plant. Do not apply fertilizers above the roots to avoid damaging the root tissue structure. Apply nitrogen fertilizer every 15 days during the growing season to promote plant growth and development. Apply potassium fertilizer and phosphorus fertilizer during the budding period to promote flowering and improve flowering quality.

6. Pests and diseases

The main disease of Forsythia suspensa is sunburn, and the main insect pests are aphids and caterpillars that occur during the growing season. Whether it is a disease or an insect pest, it must be dealt with immediately once discovered. The diseased branches and leaves must be cut off and burned, and the plants must be sprayed with professional pesticides for treatment.

Precautions for the maintenance of false forsythia

When caring for false forsythia, you should pay attention to the soil being used for too long, as nutrients will be lost and the plant will easily become compacted. Generally, the soil should be changed every 1 to 2 years, and the best time to change the soil is in spring. Before changing the soil, in order to reduce the nutrient consumption of the plant and retain nutrients to speed up the recovery of the plant after soil change, the branches and leaves should be pruned, and diseased, weak, dry and dense branches should be cut off. When changing the soil, rotten roots, dry roots and dense roots should be pruned after the plant is removed from the pot. After applying carbendazim, place it in a ventilated place to dry until the wound shrinks and then replant it.
