2. Main points of hibiscus flower care
1. Lighting
Hibiscus flowers are light-loving plants and require sufficient light to bloom. It is recommended to provide at least 6 hours of direct sunlight every day. If there is insufficient light, the plants will grow longer and flower less.
2. watering
Hibiscus flowers like a humid environment, but are intolerant of stagnant water. When watering, you should follow the principle of "see dry, see wet", that is, water after the soil surface is dry, and water thoroughly every time. Watering frequency needs to be increased when the temperature is high in summer, and watering needs to be reduced in winter.
3. Soil
Hibiscus flowers prefer loose, fertile, well-drained soil. You can use leaf mold soil, garden soil and river sand mixed in a ratio of 1:1:1, or directly purchase general-purpose nutrient soil.
| soil type | Proportion |
|---|---|
| Humus soil | 1 serving |
| garden soil | 1 serving |
| river sand | 1 serving |
4. Fertilize
Hibiscus flowers require sufficient nutrients in the long term. It is recommended to apply diluted compound fertilizer or organic fertilizer (such as decomposed cake fertilizer) every 2 weeks. Before the flowering period, additional phosphorus and potassium fertilizers can be applied to promote flower bud differentiation.
5. Pruning
Regular pruning helps hibiscus flowers maintain their shape and encourage flowering. Heavy pruning can be carried out in spring to remove dead branches, diseased branches and overly dense branches; the remaining flowers can be cut off promptly after flowering to avoid nutrient consumption.
6. Temperature
Hibiscus flowers are not cold-tolerant, and the suitable growth temperature is 15-30°C. When the temperature is lower than 5℃ in winter, it needs to be moved indoors for maintenance to avoid frostbite.
3. Common problems and solutions
| question | Reason | Solution |
|---|---|---|
| Leaves turn yellow | Too much or too little watering, lack of fertilizer | Adjust watering frequency and add fertilizer |
| No flowers | Insufficient light and nutrients | Increase light and supplement phosphorus and potassium fertilizers |
| pests and diseases | Spider mites, aphids, etc. | Spray insecticide or soapy water |
4. How to propagate hibiscus flowers
Hibiscus flowers can be propagated by cuttings or seeds. Cutting is the most commonly used method. The steps are as follows:
1. Select healthy semi-lignified branches and cut them into 10-15 cm cuttings.
2. Remove the lower leaves and keep the top 2-3 leaves.
3. Insert the cuttings into moist sand or vermiculite to maintain humidity.
4. After about 3-4 weeks, roots will take root and you can transplant.
