What should I do if I fertilize too much cyclamen
As a star flower in winter and spring, cyclamen is favored by gardening enthusiasts with its unique butterfly-shaped flowers. However, improper fertilization operations often become a pain point for maintenance. This article will systematically analyze the first aid measures for excessive fertilization and scientific management plans for flowering periods to help you cultivate cyclamen with blooming flowers. 1. First aid plan for excessive fertilization of cyclamen 1.1 Emergency dilution operation steps After excessive fertilization is found, immediately water the basin soil with clear water for 3-5 times continuously, each time at an interval of 20 minutes. It is recommended to use the dipping pot method to place the flower pot in flowing water for 30 minutes to remove 70% of the excess fertilizer through the siphon effect. During operation, it is necessary to keep the drainage holes on the bottom of the basin smooth to prevent secondary root rot caused by accumulated water. 1.2 Key measures for root restoration When there are symptoms of fertilizer damage such as scorched leaf margins, it is necessary to remove the pot to inspect the root system. Use disinfectant scissors to cut off the blackened and rotten capillary roots, leaving the main root in length no less than 8cm. After pruning roots, soak in carbendazim solution for 20 minutes, and replace with a new substrate with perlite: peat soil =1:3 to repot. 2. Scientific fertilization cycle planning 2.1 Nutrient replenishment plan for the growth period adopts the "1+2" fertilization model in the spring and autumn growth season: diluted 1500 times organic liquid fertilizer (recommended soybean cake fertilizer) once a week, and added once every half of the month. Slow release granular fertilizer containing trace elements. Fertilization in the morning and 3 hours of light can increase the nutrient absorption rate by 40%. 2.2 Special management during the flower bud differentiation period starts the phosphorus and potassium intensification plan 20 days before the bud appears: potassium dihydrogen phosphate (800 times liquid) is sprayed alternately on the leaves and the roots are irrigated, twice a week until the first flower opens. Combined with 6 hours of scattered light per day, the flower number per plant can be increased by 50%. 3. Precise control of fertilization during flowering period 3.1 Analysis of the principle of prohibiting fertilization during flowering period Fertilization during flowering period will break the C/N balance and encourage plants to divert more than 60% of nutrients to new bud growth. Experimental data show that applying nitrogen fertilizer will shorten the flowering period by 12-15 days. It is recommended to completely stop fertilization when 80% of flowers are in bloom, and the viewing period can be extended by controlling water to maintain the substrate humidity by 40%. 3.2 Key points for post-flowering recovery and maintenance: start fertilizer supplementation on the third day after the last flowers wither: first apply 2000 times seaweed to repair the root system, and then switch to balanced water-soluble fertilizer (N-P-K=20 - 20) 7 days later. Combined with pruning of residual flowers and retaining 3-4 functional leaves, the weight of the corm can be increased by more than 30%.
By mastering the trinity fertilization strategy of "first aid, regulation and maintenance", we can not only resolve the fertilizer hazard crisis, but also realize the continuous bloom of cyclamen from the end of the year to early spring. It is recommended to test the soil EC value every quarter and control it within the ideal range of 1.2-1.8mS/cm, so that this beautiful fairy from the Mediterranean can always be at the window.
