Key to summer 1: soil

1. Growth habit

Raw stone flower is native to southern Africa and likes a warm, dry and sunny environment. Therefore, the soil should have good air permeability and drainage. In this way, in case of rainstorm, the basin soil can drain quickly when it enters the water, so as to ensure the normal breathing of the roots

2. Soil selection

Ordinary granular soil or humic gravel soil and sapropel can be used to mix 2 ~ 3mm granular materials, such as honeycomb cinder, coarse sand, hematite soil, peat, etc

3. Cooling tips

When the temperature is high in summer, a layer of pebbles can be paved on the surface of the basin soil to prevent sun and cool down, which is conducive to root growth

Key to summer 2: watering

A flower friend asked, do you need not water the stone flowers when they are dormant in summer? However, there is no theory of dormancy at all for the raw stone flowers cultivated in general families. The key to safe summer is how to water and how much water to water

1. Better dry than wet

Many people have misunderstandings about watering and think that it's OK to dry it thoroughly. However, it's hot and humid in summer. It's easy to water it thoroughly, but it's difficult to dry it thoroughly. The result is either in vain or dead. If the water is less, the top should be slow, which will never have a great impact

Taking the 2-year-old seedling with the size of about 1cm as an example, the flower has not been watered for more than a month, and the state is still very full and does not grow in vain, indicating that the water demand of raw stone flower is very small

2. Watering in the evening

The pores on the leaves are closed during the day and opened at night, so the watering time should be in the evening or at night. After watering, the windows should be opened in time for ventilation. You can also choose to spray at night. p>

Key to summer 3: light

1. Indoor maintenance

In summer, indoor glass will block a large part of ultraviolet rays without shading, but it is necessary to ensure long-term uniform lighting. In addition, ventilation must be done well

2. Outdoor maintenance

Raw stone flowers like light and are resistant to high temperature, but the stronger the light, the better. Outdoor maintenance must avoid strong light exposure, and a black shading net with a shading rate of 75% can be pulled

3. Depending on the variety

Different varieties of raw stone flowers have different light resistance. Rilun jade, Lumei jade, Zixun, Fulai jade, wild jade and other varieties have strong tolerance to sunlight, while pattern jade, micro grain jade, dajinhui, Lihong jade and other varieties are weaker

Key to summer 4: pest control

The raw stone flower is often harmed by the root mealybug. The symptom is that the root is covered with milky white cotton wadding. Summer is the vigorous breeding period of the root mealybug. When the pest is serious, the raw stone flower can die slowly

Prevention and control measures

1. Eliminate insect sources: new plants should be thoroughly disinfected, and foreign basin soil should not be used

2. Physical control: in case of insect pests, the roots of the whole pot of plants shall be thoroughly pruned, pots and soil shall be changed in time. When pruning roots, rinse the white powder and adults of the roots with clean water

3. Drug control: burying some carbofuran particles in the soil around the root can achieve the preventive effect; The therapeutic drug can be treated with Guoguang scale, combined with sprinkler irrigation, with obvious effect
