When will the plum blossom blossom?

Lamei is native to central China, but it is also slightly resistant to shade, cold and drought. It is said that it is not strict with the quality of the soil, but it is suitable for light loam soil with good drainage. It usually blossoms in the depths of winter when the flowers are withering. It is born in the mountain forest. Let's take a look at when the plum blossoms will bloom.

When will the plum blossom blossom?

The flowering time of Prunus mume in southwest China is from December to January of the following year, from February to March in Central China and from March to April in North China. Usually the first flower of Prunus mume blossoms from 4 to 7 days in full bloom to 15 to 20 days at the end of the flower.

The reason why dried plum does not blossom

1. Excessive nitrogen fertilizer: some wax plums are out of control of water and fertilizer, especially excessive nitrogen fertilizer, resulting in excessive growth of branches and leaves, affecting flower bud differentiation and leading to non-flowering. Therefore, Lamei should apply nitrogen fertilizer in spring, increase phosphorus and potassium fertilizer in summer and autumn, and apply little or no nitrogen fertilizer to promote flower bud differentiation as soon as possible.

2. Excessive dampness: la Mei Xiguang, insufficient light will affect flower bud differentiation, basin soil is too wet or the place is too shady and wet, which is not conducive to flower bud differentiation. For this reason, we should "buckle water" in late summer and early autumn, and always put it in a place with sufficient sunshine. This is greatly conducive to the formation and expansion of flower buds.

3. Untopping and heart-picking: for Lamei which has entered the flowering stage, if it is allowed to branch spontaneously during the vegetative growth period in spring and summer, without necessary topping and shoot control, the flower bud differentiation and growth will also be affected because the vegetative growth is out of control. In general, when 3 or 5 pairs of leaves are extracted from the tip, the top 1 and 3 parts should be removed in time to promote the germination of lower lateral buds and the normal differentiation of flower buds. In late summer and early autumn, we should not neglect to hit the top and pick the heart.

The Culture method of Prunus mume

1. Soil: loose, fertile and humus-rich sandy loam should be selected for potted plum cultivation.

2. Watering: Lamei is resistant to drought and waterlogging, such as too high moisture, too moist soil, poor plant growth, affecting flower bud differentiation. Therefore, potted plum should keep the soil dry, usually not dry, watering thoroughly, but "dog days" high temperature season should be more watering to maintain normal plant growth, so that the normal development of flower buds.

3. Temperature: Lamei is fond of sunshine and can withstand semi-overcast. It can survive the winter safely when not less than-15 ℃. It can be cultivated in the open field in the south of Beijing. The flowering stage is at a low temperature of-10 ℃ and the flowers are damaged by freezing.

4. Pruning: wax plum has strong branching power, and there is a proverb that "there is no shortage of branches". Pruning at the right time makes it sprout more strong flower branches and make it blossom more. It is generally appropriate to prune the withered branches, overdense branches, cross branches, disease and insect branches, and leave 2 to 3 pairs of buds at the base of the annual branches, and cut off the upper branches to promote the germination and branching.

5. Fertilization: Lamei is a fertilizer-loving flower. Timely fertilization can promote flower bud differentiation and blossom more. The fertilization of wax plum is mainly based on phosphorus and potassium, while the application of nitrogen fertilizer is less, and the proportion of phosphorus, potassium and nitrogen is about 2 to 1, 0.5. In this way, the flowers of wax plum are large, many and fragrant.

6. Insect pests: Lamei has fewer diseases and more insect pests, such as aphids, shell insects, diamondback moths, curly leaf buds and so on. Aphids suck juice on tender leaf buds, shell insects suck juice on branches, and diamondback moths and leaf rollers bite leaves, new buds, flower buds and so on. In order to reduce the pollution to the flower-growing environment, soil methods can also be used to kill insects, such as shell insects can be killed with acid and vinegar solution, aphids can be killed with washing powder water, if a small amount can be killed manually.
