Cultivation Methods for Pig Bristle Grass
1. Adequate moisture
Pig bristle grass generally needs to keep the soil moist, and pay attention to keeping the moisture adequate during its growth period. Increase the air humidity appropriately in dry weather. It should not be allowed to dry out in the summer, and watering should not be done to make the soil wet for a while and then dry again, as this will cause the leaves to turn yellow.
2. Suitable temperature
Pig bristle grass does not have very strict temperature requirements, but attention should still be paid to high temperatures in summer and low temperatures in winter. In general, in winter, as long as the indoor temperature is above 5 degrees Celsius, and in summer, it should be placed in a cool and ventilated place, keeping the temperature around 25 degrees Celsius. Direct sunlight can cause direct damage to the leaves.
3. Soil requirements
The soil fertility should not be too poor. Pig bristle grass generally grows in sandy soil rich in humus, but it can also be cultivated using potting soil. Fertilization should be applied monthly, and the fertilizer should be applied to the roots. Repotting and changing soil is also important during the spring growth period each year.
