Pruning method of Primrose cutting Propagation method of Primrose

Primrose is a very representative plant in spring. As soon as you see it, you know that spring is coming, and its vitality is very tenacious, so it grows very fast, and pruning has become the key to keeping it beautiful. and if it is not pruned regularly, it will also affect its growth, so let's learn its pruning skills.

Pruning method of primrose

In general, it is best to trim twice, once after blooming in spring, to remove all the branches of that year, leaving 1 Murray 2 teeth. After growing for a period of time, prune again and remove the weak branches according to the symmetry of the post and crown branches. If the branch grows too fast, another short cut can be made in late March or early April, and one of the lateral teeth can be erased according to the growth direction of the branch. It is very important to seize the period of spring bud emergence and carry out centralized pruning and finishing.

When pruning, the adventitious buds that do not need to be retained are first erased. When the branches grow to 2 pairs of leaves, the length is about 4-5cm, the terminal buds are removed with tweezers, and the second round buds are produced in about 10 days, and then 2 pairs of leaves are retained to remove the terminal buds. After knocking out the terminal buds for three times, the pruning is completed in spring. At this time, if you continue to pick buds, there will be only a single bud, no longer uniform decentralization, after most of the nutrients stored in autumn and winter are consumed, the potted trees enter the normal pruning management stage in spring and summer.

Cutting Propagation method of Primrose

First of all, it is appropriate to take root quickly during the period of vigorous growth from July to August, and the survival rate is high. When the breeding capacity is large, it can be cut in the open field, and the minimum reproduction can be planted in the pot. Open-field cuttings should choose plots with leeward direction, high topography, favorable drainage and loose and fertile soil. When the basin is inserted, the basin soil can be loose and fertile sandy loam plus a small amount of river sand. The cuttings can be selected from the robust new branches growing in the same year, cut off the pier tips and cut into branches 10 to 15 centimeters long. Take off all the leaves at the lower part of the cuttings at 2pm and 3, and insert them into the soil. The row spacing of the plant is 8 cm, and the insertion depth is up to the length of the cuttings.

After planting, pour water thoroughly (can also be watered while cutting), and then pay attention to shade and keep the soil moist within 15 days. The light can be increased gradually after 15 days. But to prevent the sun and high temperature around noon, see dry watering. In this way, the cuttings may take root after another 15 days or so. After about 10 days of new bud growth, it can be combined with watering and applying fully mature thin book liquid fertilizer, and pay attention to weeding and loosening soil, and can be planted separately according to the need. If you plan to plant separately in spring next year, control watering directly after autumn, stop chasing, and promote the growth of new branches, timely Lignification, in order to survive the winter safely.

What if the leaves of primrose turn yellow?

1. Remove weeds, reduce the source of infection and ensure a clean environment around primroses. Secondly, control aphids and reduce transmission media.

2. water correctly, check the dry and wet condition of the soil before watering, and insist on seeing dry and wet. If there is no measure, bask in the sun immediately after watering, or use the soaking basin method to water, the amount of watering can be effectively controlled. (the soaking pot method puts the flowerpot into the water, so that the water does not pass its 2 beat 3, and the water naturally enters the soil. )

3. When selecting soil, choose the soil with good loose drainage, and when going up the pot, lay a layer of coarse sand at the bottom of the flowerpot as a waterproof layer. It is found that the air permeability of the soil is poor during maintenance, so turn the basin and change the soil in time.

4. Spring peanut needs topdressing for 2 or 3 times for a long time, mainly nitrogen, phosphorus and potassium fertilizer. Potted primrose should be fertilized with sufficient base fertilizer, nitrogen fertilizer before flowering, pruning branches and leaves and topdressing once after flowering. Reasonable fertilization should be applied according to the growth status of the plant during maintenance. Every time thin liquid fertilizer is irrigated to avoid fertilizer damage caused by too much fertilizer.

How to spend the winter with primroses

1. In winter, you can put a water basin at the bottom of the basin with a small amount of water in the basin to increase the humidity around the potted flowers and reduce the water evaporation of leaves to prevent flowers from losing water and falling leaves.

2. In winter, it also needs to be watered. When watering, the water temperature should be controlled well, and it is better to be similar to the temperature at that time, so as to prevent the primroses from freezing. Due to low temperature and slow evaporation of water in winter, watering times do not need to be too frequent, and appropriate watering can be carried out according to basin soil observation.

Whenever I go out to play in spring, I feel very happy to see large tracts of primroses. It tells people that spring is coming, and the ornamental value of primroses is very high. Generally, cutting propagation is adopted, and the survival rate of this method is very high. Can be a large number of reproduction, so the general garden appreciation will use this method.
