Gardenia fertilization method
Gardenia is famous for its white and fragrant fragrance, but if it wants to grow healthily and bloom luxuriantly, scientific fertilization is the key link. This article will systematically analyze the entire process of gardenia fertilization from time selection, fertilizer ratio to operation details to help you create a beautiful courtyard with fragrant flowers. 1. Golden cycle of gardenia fertilization 1.1 During the basic fertilization stage, the base fertilizer needs to be pre-buried. It is recommended to use a ratio of decomposed sheep manure and bone meal of 3:1, and mix 500g of each plant into the bottom soil of the planting hole. At this time, the effect is better when used with slow-release fertilizer. The Aolu 318s model is recommended to continuously release nutrients for 8 months. 1.2 During the period of vigorous growth, replenishment is from March to September, and organic liquid fertilizer is applied every month. It is recommended to choose fish protein fermentation liquor (diluted 800 times) or seaweed essence solution. Alternate use of the two can prevent nutrient deficiency. Water needs to be controlled for 2 days before fertilization, and the watering effect is best when the basin soil is semi-dry. 2. professional-grade fertilizer ratio plan 2.1 Organic and inorganic synergistic base fertilizer is recommended to combine cow dung fertilizer + humic acid slow-release fertilizer, and top dressing uses Melo acid nutrient solution (pH 5.5 -6.0). When combined with foliar spraying potassium dihydrogen phosphate (0.2% solution) during special periods, the flower buds can increase by 15%-20%. 2.2 Special nutritional management during flowering period is applied every week during the bud and bud period, and Huaduo No. 2 (N-P-K=10-30-20) is combined with EM bacterial stock solution to irrigate roots. Important tips: Adding ferrous sulfate (0.1% solution) 20 days before flowering can effectively prevent yellow leaf disease. 3. Operation specifications for refined fertilization 3.1 Scientific application techniques Liquid fertilizer needs to be diluted twice: diluted to the recommended concentration of 50%, and then replenished 24 hours later. The slow-release fertilizer should be buried in an annular ditch 15cm away from the main stem, with a depth of 8-10cm. Foliar fertilizer spraying needs to cover both sides of the leaves, and uniform atomization is preferred. 3.2 Environmental adaptation principles Choose cloudy evenings in spring and summer, and apply fertilizer in sunny and warm mornings in autumn and winter. Fertilization should be suspended when the temperature is>35℃ or <10℃. Potted plants need to follow the principle of "applying less fertilizer frequently", and the fertilizer amount can be appropriately increased by 20% for local planting. 4. Analysis of key precautions 4.1 Key points of soil pretreatment Before fertilization, a three-step process of "loosening the soil, drying the roots and moistening the soil" is required: first loosen the soil to a depth of 3cm, dry the roots for 2 hours, and moisten the top soil with clear water. This operation can increase the fertilizer absorption rate by more than 40%. 4.2 When symptoms of fertilizer damage occur (leaf tips are scorched) under abnormal conditions, immediately sprinkle with clear water three times, and apply brassinolide (0.01mg/L) to repair it. It is recommended to establish a fertilization log to record the type, concentration and plant response of each fertilizer.
Mastering these fertilization tips and regular observation and adjustment, you will be able to cultivate high-quality gardenia with bright leaves and rich fragrance. Remember that different varieties (such as Dayleaf Gardenia and Water Gardenia) need to fine-tune the fertilization plan. The highest level of flower cultivation is to gain true knowledge from practice!
