As one of the top ten famous flowers in China, rhododendrons are favored by gardening enthusiasts for their colorful flower appearance. To achieve the magical effect of blooming all year round, you need not only to master scientific maintenance methods, but also to be proficient in pot changing operation skills. This article will systematically analyze the core points of rhododendron maintenance and pot replacement, and help you create a plant landscape with flowers all year round. 1. Guidelines for the maintenance of rhododendrons blooming in all seasons 1. Variety selection and light management Special varieties such as Rhododendron in Four Seasons are the key to achieving year-round flowering. It is recommended to choose excellent varieties such as Belgian Western Rhododendron and Four Seasons Red. In spring and autumn, light is scattered for 6 hours a day. In summer, sunshade treatment is required, and in winter, light is extended to 8 hours. 2. Precise moisture control adopts the watering principle of "see dry, see wet", and the soil moisture is maintained at 60%-70%. Water is watered every morning in spring and summer, and changed to noon in winter. Special attention should be paid to maintaining air humidity. The environmental humidity of more than 65% can be maintained through atomization and spraying. 3. Scientific fertilization system applies potassium dihydrogen phosphate solution (concentration of 0.2%) every half month during the growth period, and adds organic fertilizers such as bone meal during the flower bud differentiation period. Re-cutting is carried out from March to April every year, 3-5 bud points on the main branch are retained, and residual flowers are removed in time to save nutrients. 2. The whole process of the azalea basin changing operation 1. The best time to prepare for pot change before pot change is the post-flowering dormancy period (March-April or September-October). Three days after the water was stopped, gently tap the wall of the basin with a rubber hammer and use a bamboo stick to draw a circle along the inner wall to loosen the root system. 2. Root treatment techniques After shaking off the old soil, cut off 1/3 of the old roots and all rotten roots. Soak and disinfect in potassium permanganate solution (1:2000) for 20 minutes, and dry the roots in a cool place for 4 hours until the incision is slightly dry. 3. The substrate preparation standard is based on the ratio of pine needle soil: leaf soil: perlite =5:3:2, and 5% bone meal is added as the base fertilizer. The diameter of the new basin should be 5-8cm larger than that of the original basin, and a 3 cm ceramsite drainage layer should be laid at the bottom. 4. Maintenance points after pot placement, pour thoroughly with root-fixing water after planting, and place it in a ventilated and scattered light place to slow down the seedlings for 7-10 days. Avoid applying fertilizer for the first 3 weeks and start applying thin fertilizer frequently after new leaves are unfolded. Keep the temperature at 15-25℃ and the humidity above 70%.
Through a scientific maintenance system and standardized pot changing operation, rhododendrons can continue to absorb sufficient nutrients. With appropriate environmental control, the viewing effect of "flowers continue all year round, and new looks will be displayed all year round" can be achieved. It is recommended to replace the pot soil every 2 years and combine it with pruning and shaping to create a unique rhododendron bonsai.
