The maintenance method of the latest potted triangular plum

In early summer, ordinary and simple triangular plum can be seen everywhere in many cities. it has a spiritual symbol of enthusiasm, tenacity and tenacity. With the passage of time, this kind of triangulated plum, which originated from South America with high ornamental value, has been gradually introduced and cultivated by people all over the country, and has become one of the widely used ornamental flowers and trees.

1. Distribution of soil

The cultivated soil is matured by the accumulation of loam, cow dung, rotten leaf soil and sand, and proper amount of bone powder is added when it is used. The family soil formula is as follows: garden soil: rotten leaf soil: sand = 5RV 3VR 2; peat soil: rotten leaf soil: sand: perlite = 5RU 2RV 1.

2. Selection of basin

Triangular plum should try to choose a shallow flowerpot when choosing a flowerpot, which helps to permeate the water. It is better to plant large flowers in small pots than small ones.

2. Lighting

Triangular plums like the light, the lack of light in the growing season will lead to the weakening of plant growth and affect flowering. Winter should be placed in bright places, and the daily light can not be less than 8 hours, otherwise a large number of fallen leaves are easy to appear.

3. Temperature

The suitable temperature for the growth of Prunus mume is 20-30 ℃, and the winter temperature below 5 ℃ is easy to be frozen and fallen leaves.

4. Fertilization

After the weather became warmer, nitrogen fertilizer was applied every 10-15 days, cake fertilizer and water was applied once a week during the growing period, and phosphate fertilizer was applied several times during the flowering period. Urea is still needed at the initial stage of flower branch growth to facilitate flower branch growth. Reduce the amount of fertilizer application after cool autumn, and stop fertilization in winter.

5. Watering

In summer, watering twice a day, spraying in the morning, watering once after 4 p.m., watering can be reduced appropriately after flower fade, the soil is too wet will cause fallen leaves and rotten roots; watering is controlled in winter, the pot soil is not dry, but the water should be deducted 4-5 weeks before flowering.

6. Pruning

Triangular plum is very resistant to pruning, trimming is divided into post-flowering pruning and winter pruning. The purpose of post-anthesis pruning is to adjust the plant type and promote the next batch of flowers to open early, so the residual flowers should be cut as early as possible, and the whole plant should be pruned so that they can bloom at the same time next time.

7. Pick the heart and hit the top

According to the modeling needs, the timing of topping and heart-picking was determined in the growth period of triangular plum, and the heart-picking position was determined according to the height of the plant and the position of induced branches. Generally speaking, 4-6 leaves of stem tip can be removed and topped, and the 6-leaf stage of new bud branches will remove 2 leaves and leave 4 leaves. After the lateral buds are strong, 1-2 leaves will be removed and 2-3 leaves will be left. After several times of pruning, topping and coring, the branches changed from 1 to 2, from 2 to 4, until they developed into the desired crown. In addition, remove the buds that do not need to stay.

8. Modeling

By controlling the apical dominance, we can promote the sprouting of the lower part of the plant, control the excessive growth of branches, and accelerate the growth of lateral branches to achieve the purpose of modeling. Before pruning from February to March, according to the principle of pruning the inner bore branch first and then the outer branch, remove the reverse branch, weak drooping branch, inner bore branch, overgrown branch, withered branch, overlapping branch, shade branch and interference branch and so on.

9. Change the basin

Before changing the basin, it is best to do it when the basin soil is relatively dry, because it is easier to remove the old soil and the old fine roots, and do not change the basin just after watering; it is better to remove only 1/3 or 1/2 of the old soil (keep the root mass not scattered). It's safer, and don't clean up all the soil if you're not sure.

10. Anti-freezing

Triangular plum is not cold-resistant, it is easy to freeze to death with severe frostbite, so we must pay attention to temperature changes. Generally speaking, if the temperature is lower than 5 ℃ for a long time, it may be frozen to death, even in winter in the south, the lowest can only reach 3 ℃ or so.

Note:

1. Due to slow growth or dormancy of plants in hot summer and winter, fertilization should be stopped to avoid fertilizer damage.

2. Do not apply thick fertilizer or raw fertilizer (organic fertilizer that is not fully mature) to prevent root damage, leaf coke shedding, or even the death of the whole plant.

3. It should be moved indoors in the cold winter, otherwise it will cause frostbite.
