What is the Best Fertilizer for Chinese Rose
As the leading plant among the three treasures of the courtyard, the proper fertilization management of Chinese roses directly determines the fullness and frequency of blooming. The nutrient requirements differ significantly at different growth stages, and a reasonable combination of fertilizers can keep the Chinese rose blooming from spring to autumn. This article will analyze the complete system of scientific fertilization for Chinese roses from the perspective of the synergistic use of organic and inorganic fertilizers.
Basic Fertilizer Selection for Chinese Rose
Ecological Maintenance with Organic Fertilizer
Decomposed organic fertilizer is the core of Chinese rose root care, with its slow-release characteristics improving the soil granule structure. It is recommended to use livestock manure that has been fermented for more than 60 days, with cow and sheep dung requiring open-air stacking for desalination treatment. For indoor potted plants, odorless organic fertilizers are suggested: 1. A fermentation mixture of sesame paste residue and soybean cake at a 2:1 ratio. 2. Kitchen waste compost should be supplemented with EM bacteria to accelerate decomposition. 3. Marketed earthworm dung can be directly mixed with soil.
Precise Energy Supplement with Inorganic Fertilizer
During the budding stage and post-blooming pruning stage, it is recommended to use N-P-K compound fertilizers for key supplementation: • Budding stage: High nitrogen formula (20-10-10) to promote new branches. • Bud formation stage: High phosphorus formula (10-30-20) to strengthen flower buds. • Before dormancy: Balanced formula (15-15-15) for nutrient storage.
Advanced Fertilizing Techniques for Chinese Rose
Fertilizing Position and Depth
Organic fertilizers should be applied in a circular trench 20 cm away from the main stem, with a depth of 15-20 cm. Inorganic fertilizers should be buried shallowly in a radial pattern, 30 cm away from the roots, distributed in a star shape to avoid root burn from fertilizer efficacy.
Seasonal Fertilizing Rhythm
March-April, budding stage: Organic fertilizer + slow-release fertilizer base application. May-June, full bloom stage: Weekly foliar application of potassium dihydrogen phosphate. July-August, high-temperature stage: Pause solid fertilizer application. September-October, autumn bloom stage: Supplement with humic acid water-soluble fertilizer. December-February, dormancy stage: Deeply bury bone meal winter fertilizer.
Through the scientific proportioning of organic and inorganic fertilizers, adjusting the fertilization plan according to seasonal growth characteristics, the disease resistance of Chinese roses can be effectively improved and the blooming period extended. It is recommended to establish a fertilization log to record each fertilizer ratio, observe the plant response, and gradually optimize the plan to ensure each Chinese rose can show its best condition.
