How to raise Photinia chinensis, the breeding methods and precautions / diligent fertilization of Photinia rubra

Photinia przewalskii has changeable leaf color, dense, pure and white flowers. It is precisely because of its numerous effects and functions that more and more people raise it, but if you want to raise it well, you still need scientific methods, so how to raise it? Let's take a look at the breeding methods and matters needing attention of Photinia chinensis.

How to raise Photinia rugosa

If you want to know how to raise Photinia, you must first understand its growth habits. It is a plant that likes warm and humid environment, likes sufficient light, has strong shade tolerance and drought tolerance, is afraid of waterlogging, and can grow in acidic or alkaline soil in the morning, but slightly acidic soil is the best, and the temperature requirement is relatively loose.

Culture methods and matters needing attention of Photinia rugosa

I. Environmental requirements

1. Soil

Photinia chinensis has better saline-alkali resistance than other plant walls. It has less strict requirements on soil and can grow normally in many soils, such as red soil, yellow soil and so on, but it is most suitable for slightly acidic soil.

Note: although Photinia can adapt to many types of soil, no matter what kind of soil, it must be noted that the soil is healthy and free of insect eggs and germs.

2. Temperature

Photinia rubra is relatively relaxed for temperature requirements, it can not only adapt to low temperature environment, but also can withstand a certain high temperature, so it can be planted indoors or outdoors.

Note: in the breeding methods and matters needing attention of Photinia chinensis, although the temperature requirement is not high, the most suitable temperature is 15-30 degrees. If you want to make the plant more beautiful, you can control the temperature in this range.

3. Lighting

Photinia has a very strong ability to tolerate shade and can still grow slowly in a dark environment, but it actually likes plenty of light, so try to provide it with plenty of sunshine.

Note: when there is direct light, the leaf color of Photinia will be more bright, and when the lack of light, although it can grow, but the leaf color is dim, the ornamental is slightly poor.

Second, maintenance skills

1. Fertilization

Photinia chinensis grows rapidly in spring, summer and autumn, so it should be fertilized every half a month in spring and compound fertilizer in summer.

Note: do not excessive fertilization, do not need to apply too much fertilizer at one time, it is best to apply thin fertilizer frequently, if too much fertilization may lead to leaf hypertrophy and no luster, or even withered and yellow shedding.

2. Watering

In terms of drought resistance, Photinia is relatively strong, but it prefers the humid environment, so usually should pay attention to more watering, in order not to let the soil dry, keeping the soil slightly moist is the best.

Note: Photinia chinensis is drought-resistant but not water-resistant, so watering must not be too much to avoid stagnant water in the basin soil. if stagnant water is found, check the drainage of the soil in time, and pay attention to the discharge of stagnant water.

3. Pruning

Photinia is a plant that is very resistant to pruning. In order to keep its shape more beautiful, it can be often trimmed to cut off too high and dense branches and leaves, which can promote growth and maintain beauty.

Note: generally do not prune in winter, when the wound healing speed is slow, so as to avoid germs or pests sprouting from the wound after spring.

Planting soil of Photinia chinensis

The basin soil should be loose, fertile, acidic or neutral, and it is best to plant it with sandy soil, which is conducive to ventilation.

Growth habits of Photinia rugosa

Photinia likes the warm and humid environment, and has a strong ability to adapt to the temperature. It can withstand the low temperature of minus 18 degrees Celsius and can be planted in all regions of our country.

Fertilization of Photinia rubra

The fertilization of Photinia chinensis is best based on the principle of thin application, which is carried out about every half a month in spring, and compound fertilizer is used every half a month in summer and autumn.

Pruning of Photinia rubra

The growth and development ability of Photinia is very strong, so it needs to be pruned frequently, the pruning of Photinia can be carried out in every season, but mainly in winter, mainly using the method of cutting short and thinning branches. Heavy pruning in summer is not conducive to the restoration of tree potential.

Watering of Photinia rubra

Photinia rubra prefers humid environment, but it must not be watered too much. If stagnant water occurs, it will lead to root rot and can't grow healthily. Watering time is between 8 am and 10:00 every day, or 4: 00 to 6 pm would be better.

Diseases and insect pests of Photinia rubra

Photinia rubra is also resistant to diseases and insect pests, diseases are more vulnerable to leaf spot, anthracnose and so on, pests are vulnerable to shell insects, longicorn beetles, aphids and other pests.

The Culture method of Photinia how to raise Photinia

Photinia rubra is a new best-selling variety at present. Photinia rubra is not only highly ornamental, but also very malleable, and can make various shapes. Photinia rubra is often used in gardening and is a good greening plant. Then how to raise Photinia rugosa? Then Xiaoqi shared how to raise Photinia rugosa and how to raise it.

1. How to raise Photinia rugosa

Photinia is a small evergreen tree or shrub, likes strong light, is very shade-tolerant, and likes warm and moist growth environment; it is suitable for growing in slightly acidic soil, and its climate requirements are not too strict. It can be cultivated all over China because it can withstand the low temperature of ~ 18 ℃.

Photinia przewalskii is propagated by cuttings, so it is necessary to choose branches with strong growth and no diseases and insect pests. Note that the cuttings had better use semi-lignified twigs or woody annual branches. According to these standards, cut 6cm~10cm long branches from the plant as cuttings.

Second, the culture method of Photinia chinensis

1. Soil: the pH value of soil for planting Photinia chinensis is generally 6-6.5, which requires loose and aerated soil and certain fertility. It is observed that Photinia chinensis grows well in red loam. It is necessary to dig deep tree holes before planting, and apply rotten farm fertilizer into the tree holes to make the content of organic matter in the soil reach about 2%. After planting, it is necessary to loosen the soil and weed in time to improve soil permeability.

2. Watering: timely drainage after rain, and timely spraying or watering when there is no rain in summer, so that the soil water content can be maintained between 20% and 35%. Soil water deficiency can inhibit the growth activity of Photinia chinensis, accelerate the aging and discoloration of leaves, reduce the growth of new leaves, and then shorten the ornamental period of red leaves. Therefore, maintaining proper soil moisture is the key to the maintenance of Photinia chinensis.

3. Fertilization: Photinia przewalskii grows vigorously in fertile soil. If poor growth of new shoots is found, or stops growing, fertilizers should be added in time. In the growing season, dilute nitrogen fertilizer can be applied every 7 ~ 15 days to ensure that the plant produces new shoots at the right time. When planting in the garden, the red-leaf photinia should be avoided in the areas prone to trampling, where the soil is prone to hardening, which is not conducive to watering and fertilization, thus affecting the growth of red-leaf Photinia, resulting in a poor effect of red leaves.

4. Pruning: to improve the ornamental quality of Photinia rubra, we must pay attention to pruning. Pruning is usually carried out in early spring, early summer, early autumn before germination or in the later stage of shoot growth. The degree of pruning can be determined according to the growth of the branches, which in principle is to "remove the weak and stay strong" in order to maintain the beauty of the tree. If the top of the tree is too fast and too many, it should be picked many times to promote branching, otherwise the tree shape is too thin and tall, it will reduce the ornamental effect. When trimming, the cut is left at about 0.5 cm above the section. After pruning, attention should be paid to the supplement of fertilizer to ensure the healthy growth of the tree.
