How to raise gardenia peony flowers
As a classic flower with both ornamental value and medicinal functions, gardenia peony is favored by gardening enthusiasts for its white and fragrant flowers. This article will systematically analyze the key points of full-cycle maintenance from substrate selection to post-flowering pruning to help you create a courtyard landscape with flowers. The four elements of scientific conservation of gardenia peony soil configuration points. Gardenia peony root system is sensitive to pH, and it is recommended to use an acidic substrate with pH5-6. Recommended formula: 60% peat soil +30% leaf soil +10% pine needles, mixed with sulfur powder every 2 years to adjust acidity. Pay special attention to the prohibition of alkaline substances. Materials such as coal slag and old wall soil can cause yellow leaves and fallen leaves. The intelligent watering plan implements the principle of "see dry, see wet" during the growth period (April to September), and the topsoil is watered thoroughly immediately after being dried by 2 cm. In winter, the water is controlled until half a month, and the water is slowly poured along the edge of the basin with warm water of 25℃. Special note: Early morning spray humidification during the flower bud period can extend the flowering period, but you need to avoid direct spraying of flowers. Light control strategy Ensure 6 hours of direct light in spring and autumn, and use sunshade nets to filter 50% of the light from 10 to 15 o'clock in summer. In the northern region, it is necessary to replenish light on the southbound window sill in winter. Combined with plant fill light, the light can be extended for 2 hours a day, which can effectively prevent fallen leaves. Precision fertilization sequence applies nitrogen, phosphorus and potassium balanced fertilizers (20-20-20) during germination in March, switch to high-phosphate fertilizers (10-30-20) in June, and top-dressing application of decomposed sheep manure after flowering to supplement nutrients. Keep in mind the principle of "applying thin fertilizer frequently", dilute it 2000 times every week to irrigate roots, and stop fertilizer during high temperature periods to prevent root burning. Guidelines for the pruning of gardenia peony shapes. Implement stereotyped pruning in early spring: retain 3-5 45-degree oblique main branches and remove parallel branches and crossing branches. Immediately after flowering, the branches are shortened to the second pair of leaves to promote the germination of new branches. Cut the inner branches regularly every month to maintain the transparency of the plant type. Combined with gibberellin application on the incision, healing can be accelerated.
Through a four-dimensional integrated maintenance system of soil improvement, water and fertilizer regulation, light management, and scientific pruning, and combined with pest and disease prevention measures, gardenia peony can bloom 3-4 times a year. It is recommended to establish a maintenance log to record the data of each pruning and fertilization, and gradually grasp the plant growth laws.
