How to grow false Forsythia suspensa planting methods and matters needing attention

Forsythia suspensa is a kind of temperature-loving plant, which grows best in a warm environment and is widely distributed in the south of China. Forsythia suspensa is a kind of ornamental and medicinal plant, so it is deeply loved by people, and many people want to plant it, but before planting, it is necessary to have a comprehensive understanding of its planting technology.

How to grow Forsythia suspensa

1. Seed collection: seeds are picked in September in autumn and cannot be sowed immediately that year, because it is difficult to manage after going through winter. Pick the ripe fruit and dry it. One seed should be mixed with one-third of the sand, and the sand should be wet. Mix the sand and put it into a storage pit. The size of the pit depends on the number of seeds. Just cover the soil above the ground.

2. Time: the collected seeds can be sown in the spring of the following year, generally in March in the south, later in the north, and in April, which mainly considers the temperature factor.

3. Site selection: when raising false forsythia, it is appropriate to choose places close to water sources, convenient transportation, sufficient sunshine and no stagnant water. The soil quality is better with fertile colloidal loam, vegetable garden soil and rice field. Avoid choosing shady places, places where Rain Water has stagnant water.

Planting methods and matters needing attention of Forsythia suspensa

1. Planting method: select a piece of sunny sandy land with good drainage performance and fertile soil, disinfect after turning the soil, dig several ditches with a depth of four or five centimeters, keep the distance between the ditches around 25cm, sprinkle the seeds in the ditch soil according to the appropriate distance, cover the soil, and the soil is about two centimeters thick. You can press it a little bit, not too hard. Use a spray can for water supply, the tax system is completely wet, keep wet. The seeds will sprout in about half a month to twenty days.

2, precautions: after the seedlings grow out, we should pay attention to the weeds in the field, clean them up in time, loosen the soil, and add the right amount of fertilizer. When the seedlings grow to five centimeters high, they are more stable and begin to grow between seedlings. Pull out the overdense seedlings and diseased seedlings to reserve nutrients for the strong seedlings. After that, you can grow up to ten centimeters and then grow once in a while.

Management of Forsythia suspensa after planting

1. Watering. False forsythia likes to be moist and is not resistant to drought. It is necessary to maintain an adequate water supply during the growth period to meet the needs of plant growth. Pay attention to no stagnant water in the basin, especially in the rainy season. In winter, the basin soil should be kept dry and watered with restraint.

2. Fertilization. Forsythia suspensa needs to consume a lot of nutrients during the growth period, and a lot of nutrients are needed for flowering and fruiting, so it is necessary to apply nitrogen fertilizer every half a month during the growth period to promote plant growth; some phosphate and potassium fertilizers are needed before flowering to promote flowering; the application of phosphate and potassium fertilizer after anthesis can increase the ornamental property of the fruit and prolong the viewing time of the fruit.

3. Pruning. Forsythia suspensa is more resistant to pruning. Regular pruning is beneficial to the ventilation and light transmission of plants and the trimming of plant types. Pruning, can be combined in the spring to change the basin, to cut off some of the false forsythia weak branches, diseased branches to promote its better growth. After the false forsythia blossoms, if you need to leave fruit, then do not prune, if you do not need to leave fruit, you can cut off the inflorescence, so that you can branch and blossom again.

Common insect pests and their control

1. Aphids and caterpillars. The control of aphids and caterpillars is mainly in the growth period of false forsythia plants, especially in the pruning of plant branches, timely cutting off diseased branches, so as to reduce the occurrence of aphids and caterpillars. In addition, chemotherapy can be used by spraying the leaves with 1000 times omethoate solution.

2. Drillworms. The drillworm is very harmful, it enters the stem of the plant of Forsythia suspensa in the larval stage, which leads to the failure of flowering and fruiting of Forsythia suspensa, and even more serious, the whole plant will die. The prevention methods are timely cleaning of fallen leaves and withered branches in winter to remove insect eggs, pruning branches in time to deal with damaged branches and leaves, or killing pests with 40% dimethoate EC or 80% dichlorvos solution.

3. Snails. Strictly speaking, snails are not pests, but snails can harm flowers and larvae. The prevention method is to sprinkle lime powder around forsythia forsythia to prevent and cure, in addition, it can also be caught and killed manually to reduce the harm.

Before planting forsythia, we must do a good job of site selection, and then choose an appropriate time to sow seeds in Jinzhong. After planting, fertilizer and water management should be done well, and timely pruning and pest control are needed. Only in this way can Forsythia suspensa grow well.
