1. Soil selection
To grow Guzmania, you need to choose a loose, fertile and well-drained soil type. It is best to choose slightly acidic soil rich in humus for growing. When mixing soil yourself, you can use leaf mold, sandy soil and garden soil mixed together, and the soil needs to be sterilized once before planting.
2. Light and temperature
Guzmania likes sunlight and has a very high demand for light. It is best to keep it in a sunny spot for care, and take shading measures in summer to avoid strong light scorching the plant. Guzmania likes to grow in a warm environment, and its most suitable growing temperature is around 20°C. In winter, move it back indoors to keep it warm and avoid frost damage.
3. Water and fertilizer application
When growing Guzmania, you need to water it reasonably. Keeping the soil slightly moist helps the plant grow, but waterlogging must not occur. The growth of Guzmania cannot be separated from sufficient nutrients. During the plant's growing period, a thin liquid fertilizer can be applied once every 20 days. Applying an appropriate amount of phosphorus and potassium fertilizer before flowering is beneficial for flowering.
4. Precautions
When growing Guzmania, you need to loosen the soil regularly to avoid soil compaction, which would prevent the plant's roots from breathing. The potting soil needs to be replaced with new soil once every 1-2 years, as this allows it to grow better. When caring for Guzmania, pay attention to preventing pests and diseases, and usually strengthen ventilation to give the plant a good growing environment.
