How to care for orchids when they are blooming
Orchid blooming is praised as the "fragrance of the champion," but the delicate blooming period often leaves enthusiasts at a loss. Mastering the correct care techniques can not only extend the viewing period but also avoid the regret of 'blossoming in an instant.' This article will systematically analyze the key points of blooming period management, from light adjustment to potting taboos.
Four secrets of orchid care during blooming period
1. Golden ratio of light, water, temperature, and fertilizer
Varieties such as spring orchids and black orchids should follow the '333' lighting rule: 3 hours of soft scattered light in the morning combined with 3 hours of bright diffused light. Use a thermometer and hygrometer to monitor in real-time, maintaining a substrate humidity of 40%-60% and an air humidity of 65%-75% as ideal. Special attention should be paid to keeping the day-night temperature difference within 8°C to avoid the flower buds from withering.
2. Taboos in nutritional management
During the blooming period, the use of nitrogen fertilizer should be completely stopped. A稀释3000-fold solution of potassium dihydrogen phosphate (0.03% concentration) can be sprayed on the leaves, once every 10 days. Remember to clean the accumulated water in the corolla with a cotton swab immediately after fertilizing to prevent fertilizer damage. For plants with visible flower spikes, the 'pot-in-pot method' can be used to supplement water, avoiding direct watering.
Full analysis of the risks of repotting during the blooming period
Experimental data shows that repotting during the blooming period results in a flower drop rate as high as 78%. The roots secrete special proteases during the blooming period, and any mechanical damage will block the nutrient supply channels. In case of emergency repotting, the intact heart soil should be preserved, using a substrate of perlite: bark = 1:3, and placed in a 25°C constant-temperature growing box to recover after repotting.
It is recommended to repot 2 weeks after flowering, as the nutrient return is completed at this time. Choose a breathable purple sand pot, with a pot diameter 3-5 cm larger than the original pot. Remember 'three parts root pruning and seven parts care,' keep the healthy crystal head, trim the black and rotten roots, and seal the cut with wood ash.
