How to cultivate watermelon and pepper grass must do these points.

Watermelon pepper grass, also known as bean green pepper grass, is affectionately called watermelon pepper grass because of its leaves with lines like watermelon. Watermelon pepper grass likes the environment of high temperature, humidity, semi-shade and high air humidity. In order to maintain the beautiful markings of the leaves, the following must be done:

How to cultivate watermelon and pepper grass:

1. Matrix

It needs to be cultivated in loose, fertile, well-drained soil and grows poorly in clay. The basin soil should be mixed with coarse sand or cinder ash. It can also be cultivated with peat perlite.

2. Temperature

The optimum temperature for growth is 20-30 ℃. When the air temperature is more than 30 ℃ and below 15 ℃, the growth becomes slow. The lowest temperature in winter should not be lower than 10 ℃, otherwise it is vulnerable to freezing injury. There are even physiological diseases.

3. Soil

The basin soil is mainly composed of rotten leaf soil and mixed with a small amount of river sand.

4. Lighting

Because the watermelon skin pepper grass is more shady, so usually should be placed in the indoor bright scattered light, avoid strong light direct. Spring and autumn should be moved to a well-ventilated and slightly sunny place for maintenance. Like semi-overcast or scattered light, you can only maintain the whole sun in winter, shade 50 {bf} in summer, otherwise it is easy to burn the leaves. But too shady, the leaves are dim, grayish green, and the markings are not obvious.

5. Moisture

It is necessary to keep the basin soil moist during the growing season, but there can be no stagnant water in the basin, otherwise the roots and leaves will rot easily, and even the whole plant will die. In summer and dry season, water should be sprayed on the leaf surface 2 or 3 times a day to increase air humidity and promote the formation of leaf markings. Fear of both drought and waterlogging, drought will wilt, yellow, or even death; waterlogging will produce root rot. The basin soil can be kept slightly moist, and it can also be watered when the basin soil surface is dry. In winter, if the temperature is slightly lower, watering should be controlled to make the basin soil dry and wet alternately.

6. Fertilizer

Usually need to apply thin pancake fertilizer or compound fertilizer once a month, nitrogen fertilizer should not be too much, such as lack of phosphate fertilizer, it is easy to cause leaf markings to disappear and reduce the ornamental effect. To apply balanced fertilizer, do not apply nitrogen fertilizer alone, otherwise the stripes of "watermelon" will not be obvious and the ornamental value will be greatly reduced. It is best to use thin liquid fertilizer to irrigate basin soil, too thick fertilizer is easy to cause plant necrosis.

7. Humidity

Need high air humidity, not resistant to drying, in addition to normal watering, but also often spray water to the plant, if there are conditions, it is best to sprinkle water to humidify the growth environment, the effect is good. The growth of leaves is extremely abnormal in a dry environment.

8. Disease and pest prevention

There are few diseases and insect pests, and the diseases are common in leaf spot, which can be controlled by spraying carbendazim, dipropion and so on. The main insect pests are red spiders and shell insects, which can be sprayed with special insecticides, such as triclofenac, Nisolan, parathion and chlorpyrifos to control shell insects. Attention should be paid to the disinfection of cultivation places, pots and pots and soil. Root rot and scab are harmful, and spraying Bordeaux solution can control the spread of the disease.
