The method of Cuttage Propagation of Rehmannia glutinosa when to sow

Reticulate grass must be no stranger to it, and its popularity in the market is very high at present. Because of its high ornamental value, many people like to buy it. Officially, because of this, there are a lot of people growing it now. Before planting, everyone must be most concerned about its planting technology and time.

The method of Cuttage Propagation of Rehmannia glutinosa

1. The best cutting time is spring and autumn. First of all, we should choose a strong mother plant, not any one can. For the selected reticulate grass, it is best to spread the branches. Then select the branches with terminal buds, about 5 cm in length and 3-5 stem nodes, cut off the leaves of the stem branches inserted into the soil, or cut off half of the leaves to reduce the consumption of nutrients.

2, the prepared branches will be cut in the flowerpot, about 10 centimeters of the flowerpot need to cut 8-10 branches, and then cultivate in a small pot. After cutting, put it in a cool and ventilated place and give it proper light. It can take root in 2-3 weeks. When the leaves gradually recover and grow small tender leaves, apply a small amount of slow-release fertilizer, and carry out proper pruning and coring. If you know enough sunshine and nutrients, you can make the cuttings grow quickly.

3. The growth of reticulate grass needs plenty of sunlight, otherwise, the stems and leaves will easily grow and lose their ornamental value. Once the reticulate grass grows in vain, it is difficult to recover. In addition, the reticulated grass is afraid of cold, the temperature is too low, it is easy to appear the phenomenon of falling leaves. It is not easy to cuttage in Spring and Autumn, so don't catch blind in winter.

When will the grass be sown?

The grass can be sowed all the year round under the suitable temperature, and the sowing effect is the best when the temperature is slightly higher from May to September.

How to plant reticulate grass

1. When selecting flowerpots for planting reticulate grass, we should consciously choose flowerpots with relatively shallow depth, and the bottom of the pot had better be covered with waterproof layer, which can make its drainage performance better. After the flowerpots are ready, we will prepare the soil.

2. The soil can be prepared by ourselves with good drainage performance and sufficient fertility. in order to achieve this effect, we usually mix peat soil, rotten leaf soil and river sand.

3. After preparing these, you can pot the cutting seedlings of reticulate grass. Be careful not to damage the root of reticulated grass when transplanting. It is easy to burn root after touching fertilizer, so avoid fertilizer when transplanting reticulated grass.

4. After planting the reticulate grass into the soil, it should be watered immediately, and the soil should be watered thoroughly, so that the newly transplanted reticulated grass root can be integrated with the new soil, and then normal maintenance can be carried out.

Management of reticulate grass after planting

1. Lighting: reticulated grass prefers medium-intensity light and avoids direct sunlight, but its shade tolerance is also strong. It's best to put it by a bright window indoors.

2. Watering: you must be careful when watering the reticulate grass. If the potted soil is completely dried, the leaves will roll up and fall off. If it is too wet, the stem will rot easily.

3. Fertilization: for plants with exuberant growth, reticulate grass can apply nitrogen-based compound fertilizer with a concentration less than half of the normal concentration every half a month.

4. Temperature: reticulate grass likes warmth, the suitable temperature for growth is 18-25 degrees Celsius, the cold tolerance of reticulated grass is poor, the leaves will suffer cold injury when the air temperature is lower than 12 degrees Celsius, and the plant may die at about 8 degrees Celsius.

5. Diseases: the common diseases of reticulate grass are leaf rot and root rot, the leaf rot is sprayed with 1000 times of carbendazim wettable powder, and the root rot is sterilized by soaking the root with 1000 times of streptomycin.

6. Insect pests: the pests of reticulate grass are harmful to shell insects, red spiders and snails. Shell insects and red spiders are sprayed with 1000 times of omethoate EC, and snails can be caught manually or trapped by snails.

The planting time of reticulate grass can be determined according to the local temperature. When planting, we should first do a good job in the proportion of soil, and then choose the appropriate time to plant. If you want it to grow better, you can choose the method of cutting to propagate, and then strengthen the management.
