What are the habits and cultivation of hawthorn?

1, temperature:

Crataegus pinnatifida is a temperate tree species, which has strong cold tolerance, can endure the cold of-15 ~-20℃ for a long time, and can also resist high temperature.

2. Lighting:

Hawthorn likes sunshine and is more tolerant to shade, but if the light is too weak, the branches will grow thinner, the leaves will be thin and pale, the flowers and fruits will be poor, the fruits will become smaller and the colors will be poor. So potted plants are best placed in sunny places.

3. Variety selection

Generally, potted hawthorn should choose varieties with late fruit maturity, large fruit shape, bright red color and strong cold resistance, such as Shandongda Jinxing, Hongmian Mian, Fulihong, Cold Dew Red, Yubei Red, Dawang Hawthorn and Xifeng Red.

Step 4 use soil

Hawthorn grows best in slightly acidic sandy loam.

Generally, soil pH can grow normally in the range of 6, 0 ~ 7 and 5, but it will grow poorly in places with too strong alkalinity and low terrain, and the slender branches and leaves are easy to turn yellow and dry, or even cannot grow at all.

If ordinary soil is used as potting substrate, you can add about 1/3 substances rich in organic matter, such as peat, humus, fermented mushroom residue, sawdust and so on. It is very beneficial to the growth of hawthorn.

In addition, the domestic data also introduced the suitable potting substrate formula, such as 1 peat+1 manure+1 slag, 1 vermiculite+1 manure+1 coarse sand, 2 humus +2 garden soil+60.

5. On the washbasin

Hawthorn is a small tree with well-developed root system, which is mostly distributed in the soil layer of 20 ~ 60 cm depth. When potted, it is advisable to use a large deep basin with a diameter of 30 ~ 40 cm and a depth of about 30 cm.

Grafted seedlings with vigorous growth should be planted in pots before germination in February-March in spring, watered with root water in time, and then placed in a cool place for about 1 week, during which the soil should be kept moist, and then moved to the sunny place for normal management.
