Does the orchid sprout mean that it will bloom soon?
Whenever orchids sprout tender green shoots, flower friends are always full of expectation-does this mean that flowering is about to come? As one of the top ten famous flowers in China, the growth cycle of orchids does have specific rules. This article will provide an in-depth analysis of the correlation mechanism between orchid germination and flowering, and share professional maintenance skills. 1. Analysis of orchid germination and flowering cycles 1.1 Tips for identifying bud types Orchid germination includes two forms: leaf buds and flower buds. The leaf buds are pointed and cone-shaped, and the base is surrounded by sheath leaves; the flower buds are round and full, and granular buds can be seen at the top. Correct identification of bud type is the key to judging flowering time. 1.2 The characteristics of the growth cycle stage range from germination to flowering: leaf bud growth stage (3-5 months) → dormancy and differentiation stage (1-2 months) → flower bud extraction stage (15-30 days). Spring orchid, Cymbidium and other varieties complete flower bud differentiation from September to November, and bloom in the spring of the following year. 2. Comprehensive strategy for flower promotion and maintenance of orchids 2.1 Light control plan During the flower bud differentiation period, light needs to be scattered for 4-6 hours per day. You can use direct morning + noon shade mode, and use a sunshade net to control 30% light transmittance. Light can be increased to 8 hours in winter. 2.2 The key points of water and fertilizer management adopt the "two-stage" fertilization method: nitrogen, phosphorus and potassium balanced fertilizer (20-20-20) is used during the growth period, and potassium dihydrogen phosphate (diluted 1500 times) is transferred during the flower bud period. Combined with the watering method of "see dry, see wet", the substrate humidity is maintained at 40%-60%. 2.3 Environmental parameters are controlled to maintain the temperature difference between day and night of 8-10℃, 25-28℃ during the day, and 15-18℃ at night. The air humidity is 60%-70%, which can be achieved by laying ceramite on trays and injecting water. Rotate the flowerpot regularly to ensure uniform light reception. III. Solutions to common problems For the phenomenon of "only germination but no flowering": check whether long-term application of high nitrogen fertilizer leads to excessive growth, or insufficient light affects flower bud differentiation. It is suggested to apply EM stock solution once a month to improve the substrate, and spray boron fertilizer on the leaves to promote flowers.
Through scientific conservation, orchids can bloom about 3-6 months after germination. Mastering its growth laws and combining environmental control will surely allow this "King's Fragrance" to bloom as scheduled, showing the unique elegant charm of orchids.
