How to water Selaginella officinalis (how often) the culture methods and matters needing attention of Selaginella officinalis

Selaginella is also called Nine Death Resurrection Grass, because Selaginella can "die" and come back to life. Selaginella grows in unusual environments and is highly resistant to drought. Because it also has a high ornamental value, so many people will raise a pot at home, but recently some people have reported that it is very troublesome to water, then follow Xiaobian to understand how it is watered.

How often do you water them?

Selaginella is extremely resistant to drought. But during the growth period, it needs a lot of watering to keep the pot soil fully moist. Plants love moisture and spray their foliage with warm water every day. Do not spray with cold water, otherwise it will be harmful to the leaves.

Selaginella cultivation methods and precautions

1. Selaginella cultivation method

1. Soil

For breeding Selaginella, the pot soil needs to be loose and well drained. Sandy soil is good, but you can also mix some soil yourself.

2. Temperature

Selaginella vitality is relatively strong, it likes warm environment, in the growth of the appropriate temperature is about 20℃, winter should be careful not to be lower than 0℃.

3. Light

Selaginella like semi-shady growth environment, general potted culture to put it in a damp place without direct vision.

4. Watering

Selaginella is drought-resistant, but it needs a lot of watering during its growth, keeping the pot moist, because it likes moisture, so it needs to be sprayed frequently, but be careful not to be cold.

5. Fertilization

Fertilizing Selaginella is usually done once every half month.

Second, the cultivation of Selaginella cautions

1. Change the basin

When breeding Selaginella, it is necessary to change pots. Generally, shallow pots can be selected. The time to change pots is in spring. If you do not change the basin, you should also change the soil.

2. Diseases and pests

General Selaginella occurrence diseases and insect pests, to take timely measures to prevent and control. To get rid of diseased branches and leaves in time, pests should first be artificially repelled, or some pesticides should be sprinkled to kill insects.

Propagation method of Selaginella

1. Spore reproduction

Generally select the stem segment with mature sporangia, cut about 1.5cm from the top of the branch, sprinkle some fine sand on the cut of the stem segment to keep the humidity of the cut and prevent water loss. Under the temperature condition of about 20℃, new plants can grow after about 9 months.

2, stem propagation

Stemming propagation is to cut the stolon of Selaginella into stem segments of about 5 cm and place them in the soil. Keep the soil moist and they can germinate and grow soon.

3. Leaf reproduction

Selaginella leaves inserted into the soil, timely watering moisture, placed in the semi-shade, soon can take root and send out new leaves.

Common diseases and insect pests of Selaginella chinensis and their control methods

1. Leaf spot disease

Symptoms: leaf spot disease occurs frequently in rainy weather, and it is easy to get sick in humid weather, because humid weather is easy to breed germs. Brown spots appear at the beginning of the disease. The edges of the leaf spots appear water-soaked and chlorotic, and they extend outward in a ring-like pattern. Black brown mold spots will appear in the center of the late disease spots, which will become black brown mold layers under wet conditions.

Control methods: timely removal of diseased leaves, available during the outbreak of 100 times diluted carbendazim spray.

2. Anthrax

Symptoms: Anthracnose initially occurs on leaves, and in severe cases spreads to petioles. At the beginning of the disease, the small macula was immersed in water, and gradually spread into a ring pattern. At the later stage, the disease spots formed a dry leaf and produced small black spots arranged in a ring pattern.

Control methods: strengthen conservation, increase phosphorus and potassium fertilizer to enhance plant resistance; early stage of disease can be diluted 1000 times the equivalent Bordeaux mixture or diluted 1500 times the solution of Tobzin spray.

3. Brown soft scale

Symptoms: Brown soft scale can harm many kinds of plants, in Selaginella more frequent. Brown soft scale generally cluster on leaf surface or tender leaf, suck plant juice through piercing mouthparts, easily induce coal pollution disease, affect photosynthesis of plant, finally cause weak growth potential, leaf withered.

Control methods: the number of insects is not much, you can use a brush or bamboo and other things will be insect body scraping; in the incubation period of the nymph can be diluted 100 times dimethoate emulsifiable or omethoate emulsifiable spray.

The above is about how to cultivate the general content of the Selaginella, in fact, as long as you master the correct breeding method, Selaginella is still very good to raise. Selaginella's vitality is very tenacious, especially drought resistance, loss of water supply not only will not die of drought, but also very likely to reproduce.
