How to grow Forsythia suspensa

1. Soil selection: Forsythia suspensa is suitable to grow in calcareous soil with fertility and smooth drainage, and the more fertile garden soil is the best.

2. Fertilization: mature thin liquid fertilizer or compound fertilizer should be applied to Forsythia suspensa every 15-20 days in spring and autumn, and fertilizer with high phosphorus content such as potassium dihydrogen phosphate can be sprayed to the leaves in autumn to promote the formation of flower buds.

3, temperature: forsythia has no strict requirements on the climate, like the warm environment, but also more resistant to cold, can tolerate the semi-shady environment.

4, light: forsythia likes the environment with plenty of sunshine, it should be provided with good light on weekdays, but it should not be exposed for a long time.

5. Watering: forsythia can tolerate drought and grow better in a moist and moist environment, so watering does not need to be too frequent, watering once a week can ensure its growth.

Planting methods and matters needing attention of Forsythia suspensa

I. planting methods of Forsythia suspensa

1. Soil

Forsythia does not have high requirements for soil, but the growth effect is the best in loose, fertile, draining and breathable soil.

2. Watering

The soil can not be too dry, usually to keep the basin soil moist, but can not accumulate water, pay attention to drainage in the rainy season to avoid plant rotting roots caused by stagnant water in the basin soil.

3. Lighting

Forsythia likes the sun, although it can withstand half-shade, it is best to keep it outside in a sunny and well-ventilated place during the growing period, and there is no need to block the sun when it is hot in midsummer.

4. Temperature

Forsythia is cold-resistant and can spend the winter in cold rooms or bury flowerpots in outdoor shelter from the wind and the sun.

5. Fertilization

Forsythia had better apply mature thin liquid fertilizer or compound fertilizer every 15-20 days in spring and autumn. Fertilization should be stopped in summer, and potassium dihydrogen phosphate and other fertilizers with high phosphorus content can be sprayed to the leaves in autumn to promote the formation of flower buds.

II. Points for attention

1. Controlled watering in winter

In winter, we should try to reduce the number of watering and the amount of water, keep the soil from freezing, forsythia can survive the winter safely.

2. Pay attention to pruning branches and leaves

For the fruiting branches that have blossomed and fruited for many years and began to senescence, cutting or re-pruning (that is, cutting off the branches 2 and 3) can promote the emergence of strong branches below the cut, restore the tree potential and improve the fruiting rate. Autumn pruning is mainly sparse pruning, in addition to maintaining 3-7 exuberant trunk per stump, the other thin, withered and aging branches should be cut off according to the situation. In winter, cut off withered branches, wrapped branches, overlapping branches, crossed branches, weak branches, as well as overgrown branches and disease and insect branches.

The reason why Forsythia suspensa only blossoms but does not bear fruit

1. the seed setting rate of self-pollination is low.

The fruit-setting rate of Forsythia suspensa is very low, on the one hand, because the seed-setting rate of self-pollination of Forsythia suspensa is very low, basically about 4%, only the seed-setting rate of cross-pollination will be higher, but family planting is generally unable to carry out cross-pollination.

2. Growing branches to disperse nutrients

On the other hand, because of the strong growth of the branches of Forsythia suspensa, many growing branches are drawn every spring, which have no ornamental effect, but also cause the dispersion of the main nutrients of the branches, resulting in low fruit rate of Forsythia suspensa.

What if Forsythia suspensa blossoms but doesn't bear fruit?

1. Promote cross-pollination

When transplanting, alternate cultivation of long-styled plants and short-styled plants to promote cross-pollination.

2. Reasonable pruning

After Forsythia suspensa was planted, when it was about 1 meter high, the top tip was cut off after defoliation in winter, coring and multiple branches were carried out in summer, from which 3-4 fully developed lateral branches were selected and cultivated into main branches in different directions.

3. Rational fertilization

After forsythia pruning, topdressing rotten compost or stable manure can also be combined with calcium superphosphate, digging a hole next to the plant and covering the soil, choking roots and cultivating soil, so as to promote the growth of young trees, blossom and bear more fruit.

Forsythia suspensa is a good ornamental flower plant in early spring. Every year in early spring, Forsythia suspensa blossoms, golden flowers hang all over its branches, flowers are luxuriant and dense, it looks like a sea of flowers from a distance, and sends out fresh smells from time to time.
