How much is a deciduous shrub Forsythia suspensa seedling? When will it blossom? How do you raise it?

Forsythia, also known as Huanghuagan, Huang Shoudan, is a common deciduous shrub on hillsides and under forests in China. It is widely used as medicine because of its functions of clearing heat and detoxification, relieving pain, and regulating menstruation. How much is a forsythia seedling? When will it blossom? How do you raise it?

Seedling price:

According to the price of the mall, the price of the seedlings is about 10 yuan. However, affected by the origin, variety and the growth years of seedlings, the price of forsythia seedlings is slightly different. The actual price is based on the local area.

Flowering time:

Under normal circumstances, the florescence of Forsythia suspensa is in early spring, mainly from March to April. When it blossoms, the color is bright, the trees are full of yellow flowers, and exudes a faint aroma.

However, Forsythia suspensa sometimes blossoms out of season, and it is also possible to see Forsythia suspensa in autumn or winter when Forsythia suspensa does not blossom. This is a typical two-degree blooming phenomenon, which is relatively rare.

Why can it blossom out of season

The off-season flowering of Forsythia suspensa has something to do with the differentiation of flower buds of Forsythia suspensa in summer and autumn. if the growth conditions are more suitable and the temperature is maintained at about 14 ℃ for a long time, then the growth of Forsythia suspensa will be disordered and the phenomenon of secondary flowering will occur, but the duration of this phenomenon is relatively short, usually only more than ten days. If the temperature drops faster, the flowers of Forsythia suspensa will soon wither.

In addition, Forsythia suspensa counterattack flowering may be the influence of the small environment. If the growth environment of Forsythia suspensa is leeward and the temperature is high, it is possible to induce Forsythia suspensa to blossom.

The harm of off-season flowering

Forsythia should not blossom when flowering, although it will create a more peculiar landscape, but it will still do some harm. Out-of-season flowering will consume the nutrients of Forsythia suspensa early, which will affect the flowering next year and affect the fruit.

However, out-of-season flowering can also cultivate different landscapes and reflect different economic benefits.

The reason why it 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.

Solution:

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.

Planting techniques:

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.
