How to make Cymbidium bloom
As a species with great ornamental value in the orchid family, Cymbidium is favored by gardening enthusiasts for its huge flower ears and bright colors. Many flower lovers often encounter the problem of plants only growing leaves but not blooming during the maintenance process. This article will systematically analyze the key elements of flower promotion and explain in detail the special maintenance methods during flowering. 1. Four elements to promote flowering of Cymbidium hybridum 1. Scientific light control Cymbidium hybridum is a positive orchid plant and requires 4-6 hours of scattered light every day. Direct light in the morning can be accepted in spring and autumn, and a sunshade net needs to be used to filter 50% of the strong light in summer. In winter, it should be placed on the south-facing window sill to stimulate flower bud differentiation through photoperiod changes. 2. Precise moisture management adopts the watering principle of "see dry, see wet", and water is poured thoroughly when the substrate surface is 2 cm dry. It is recommended to use rainwater or tap water that is left standing for 3 days, and use foliar spray to maintain 60% air humidity in summer. Water control in winter requires maintaining micro-moisture in the substrate to avoid frostbite of fleshy roots. 3. The temperature gradient controls the temperature difference between day and night to be maintained between 8-10℃, maintained at 22-25℃ during the day, and no lower than 12℃ at night. The flower bud differentiation period requires 2 weeks of low temperature stimulation of about 15℃, and direct air conditioning should be avoided at this stage. 4. Nutritional cycle management Apply nitrogen, phosphorus and potassium balanced fertilizers (20-20-20) every half month during the growth period, and use high-phosphorus and potassium fertilizers (10-30-20) during the bud appearing period. Starting from September, potassium dihydrogen phosphate foliar fertilizer will be applied three times in a row at intervals of 10 days to promote the development of flower ears. 2. Guidelines for fine maintenance during flowering period 1. Adjust the light intensity and move it to bright scattered light areas after flowering to avoid direct sunlight causing scorching petals. Use a double curtain with a light blocking rate of 30%, and maintain a light intensity of 5,000 - 8,000 lux. 2. The moisture supply strategy uses the basin floor immersion method to maintain the substrate humidity of 40%-50%, and the air humidity is controlled at 55%-65%. Watering to avoid flowers should be completed before 10 a.m. 3. Environmental stabilization measures keep the temperature in the range of 18-22℃ and avoid temperature differences exceeding 5℃. Stay away from heating outlets and ventilation aisles and use a humidifier to maintain stable humidity. 4. Points for post-flowering management are to cut off residual flowers in time to retain 3cm flower stems, and supplement slow-release fertilizers to restore plant vitality. After 45 days, plant segmentation and pot replacement can be carried out, using a mixed matrix of pine bark + volcanic rock (3:1).
Through systematic maintenance and management, Cymbidium can continue to bloom for 60-90 days during the Spring Festival. After mastering the key flower promotion techniques, it is recommended to conduct flower bud differentiation inspections in September every year and adjust the maintenance plan in a timely manner. Plant growth lights and automatic irrigation systems can be used together to build an intelligent maintenance environment.
