What's wrong with growing flowers but not blooming?
The lush green plants but no flowers bloom is a common problem for many flower lovers. Why does the seemingly healthy plant not bloom? This article will analyze the underlying causes of the flower "strike" through five major maintenance elements and provide practical solutions. 1. Nutritional imbalance affects flower bud differentiation 1.1 Typical manifestations of nutrient deficiency When the basin soil is not supplemented with nutrients for 6 consecutive months, the leaves will show symptoms such as yellowing and shrinking. In particular, the lack of phosphorus and potassium directly affects the energy supply required for flower bud formation. 1.2 Scientific fertilization techniques suggest adopting the principle of "thin fertilizer and frequent application", and adding potassium dihydrogen phosphate solution diluted 2000 times once every half of the month during the growth period. Switch to high-phosphorus water-soluble fertilizer 30 days before flowering, and combine it with decomposed sheep manure organic fertilizer for better results. 2. Key balance in water management 2.1 Damage cycle of drought stress When the soil water content is below 30% for 10 days, plants will activate self-protection mechanisms, prioritizing maintaining vital activities and inhibiting reproductive growth. Except for meaty plants. 2.2 The precise watering plan adopts the "see dry, see wet" method, and water is poured thoroughly when the surface soil is 2cm dry. Humidity-loving flowers such as rhododendrons and gardenia need to maintain the air humidity of more than 60%, and can be combined with atomization and humidification. 3. Precise control of light intensity Positive flowers such as roses and bougainvillea require direct light for more than 6 hours a day, while Phalaenopsis and Anthurium require a scattered light environment. Use a light meter to measure and maintain the light intensity of 30,000 - 50,000 lux before flowering. 4. Preventive management of pests and diseases. Pests such as aphids and red spiders can cause flower buds to fall off, and fungal diseases such as powdery mildew and gray mold directly damage flower organs. It is recommended to spray the Melia oil biological preparation once a month to maintain environmental ventilation. 5. Dynamic optimization of the root environment. It is recommended to change the pot once a year for potted flowers and mix 30% perlite to improve breathability. Use bamboo sticks regularly to loosen the soil. When the EC value is greater than 1.5mS/cm, it is necessary to leach and accumulate salt. Hardened soil can be improved by adding 5% humic acid.
Through systematic control of the five major factors, 90% of flowering plants can return to normal flowering cycles. It is recommended to establish a maintenance log to record data such as water and fertilizer management, environmental parameters, etc., and gradually understand the personalized needs of different flowers. When the plants resume flowering, you can try flowering control techniques to achieve annual viewing.
