How much water to浇 when the Hippeastrum blooms
Hippeastrum is favored by horticulture enthusiasts for its brilliant and large flowers, and the water regulation during the blooming period directly affects the quality of the flower spike growth and the duration of the blooming period. As a typical bulbous flower, its succulent roots are extremely sensitive to water, and mastering a scientific watering method can prevent bulb rot and promote perfect blooming of flowers. This article will systematically analyze the key points of water management during the peak blooming period of Hippeastrum, from water requirements, irrigation techniques to risk prevention and control.
Analysis of water requirements during the blooming period of Hippeastrum
Daily watering amount control standard
During the peak blooming period, the daily water requirement can reach 300-500ml per plant, with the specific amount depending on the diameter of the pot: a 15cm diameter pot requires about 400ml of water, and a 20cm pot requires 600ml. The need for补水 can be judged by the color change of the potting soil, with the top 2cm of the substrate drying out indicating the need for补水.
Method for monitoring soil moisture
Use the bamboo stake insertion method to test the deep moisture level, with the best time for补水 being when only the tip of the bamboo stake is slightly moist after removal. Using an electronic moisture meter in conjunction provides more accurate results, maintaining the substrate moisture between 60-70%.
Scientific watering step-by-step breakdown
Time-sharing irrigation techniques
Implement a morning and evening double-time irrigation strategy: supplement 70% of the water consumed during the day at 7-8 am, and the remaining 30% at 17-18 pm. Avoid watering during the high-temperature noon period to prevent root stress reactions.
Precision water control operation guide
Use a long-necked watering壶 with a narrow spout to slowly pour water along the pot wall, completing a single irrigation in three stages: first wetting the surface, second penetrating the middle layer, and third ensuring thorough soaking. Wait for 10 seconds after water comes out of the pot bottom before stopping.
Taboos and risk avoidance in maintenance
Watering method misconceptions
Prohibit watering the center of the leaves to avoid flower spike mildew, and avoid using excessive amounts of water that can damage the soil structure. During low-temperature winters, if continuous blooming occurs, the water temperature should be preheated to 20°C before use.
Solution for waterlogging
If the potting soil is too wet, immediately elevate the pot to enhance drainage, and use absorbent cotton cloth to wrap around the pot wall to accelerate water extraction. In severe cases of waterlogging, replace the substrate, retaining 1/3 of the original soil to protect the roots.
Through precise water regulation, the blooming period of Hippeastrum can be extended to 20-25 days. It is recommended to adjust the strategy based on the ambient temperature: increase the water by 10% at above 25°C, and reduce the irrigation by 15% at below 18°C. During the maintenance process, it is necessary to pay attention to both light and nutrient supply to achieve the best ornamental effect.
