Jasper is a kind of perennial herb, also called Douban green. It is a common small potted plant in daily life. It can be placed on tea table, desk, computer and TV. Jasper can also absorb radiation, which is beautiful and healthy. How to raise such practical Jasper? Let's study together.
The basic knowledge of cultivating Jasper in pot: the best breeding time: Jasper can be propagated in spring and autumn or in May to June.
The best growth temperature: Jasper likes to be warm, the suitable growth temperature is about 25 ℃, and the winter temperature should not be lower than 10 ℃. Jasper can take root 15 days at 20-25 ℃.
Requirements for growth humidity: Jasper likes to be wet. Potted plants should keep the soil moist without ponding. Watering less is better than more. In principle, see watering after drying.
The best growing soil is river sand. Peat soil and perlite or vermiculite can be used to avoid too much water in the culture medium. Generally, the water content of the culture medium is 40-60%.
Appropriate application of fertilizer: apply fertilizer once a month until overwintering, and control water and fertilizer during overwintering.
The best growth light: Jasper likes shade, avoid direct sunlight, and should grow in half shade. In winter, you can have a proper sun in the morning.
The precautions for cultivating good Jasper near the computer: pest control: there are few Jasper pests, but excessive soil moisture often causes leaf spot disease and stem rot, occasionally causing damage of scale insects and slugs, so timely control is needed.
Basin soil replacement: generally replace basin once every 2-3 years to keep soil vitality and make Jasper grow better.
Main points of pruning: for the newly propagated young seedlings, the number of branches should be increased when the height of the seedlings is about 10 cm. The pruning of the large plants is generally determined by the growth, and the branches are cut short, so that the plant type is fuller and the appreciation value is higher.
Jasper propagation: propagation by ramets and leaf cuttings. In spring and autumn, it propagates in separate plants. During the period from May to June, the whole leaf was used for propagation. The leaves with petioles were about 1cm long, which were inserted to 1 / 3 of the leaves. The substrate was river sand, which could take root 15 days under the condition of 20-25 ℃. Pay attention to keep the substrate moist and certain air humidity.
Jasper culture and soil culture on the balcony: Jasper culture: it is better to carry out the green water culture of bean petals in April and may. Take the soil culture plants with good plant shape, carefully wash the soil at the root, remove the dead roots and leaves. Soak in 0.05% potassium permanganate solution for 10 minutes, then plant in the container after cleaning, fix the root system with medium, and inject water, so as to immerse 1 / 2-2 / 3 of the root system. It is worth mentioning that the green stem and leaf of Douban are tender, and it is better not to touch water. At the initial stage of hydroponics, fresh water should be changed once every two to three days, and new roots can grow one week later. When the new roots grow to more than 5cm, the container and plant should be moved to a place with sufficient scattered light for maintenance, and then the foliage plant nutrient solution should be used for cultivation, and then the nutrient solution should be changed once every half a month.
Jasper soil culture: the organic substrate with good air permeability and water conservation, such as peat soil plus perlite or vermiculite, with a proportion of about 6:1, should not be too much water in the culture substrate, and generally maintain 40-60% water content in the culture substrate. The experience of cultivating Jasper: 1. Jasper is afraid of heat in summer, so it can be put under the shade to spray water to cool down, but it should be noted that overheating and excessive humidity will cause the stems and leaves to turn black and rot.
2. Jasper maintenance should avoid direct sunlight, otherwise it will burn the leaves and leave ugly spots. It should be maintained in the half shade, so as to make the leaves plump and transparent!
