How to maintain Yushu? There are many flowers
As an evergreen variety among succulent plants, Yushu has jade-like leaves and white flower clusters that complement each other. But in order for Yushu to bloom luxuriant flowers, scientific maintenance methods are needed. This article will systematically analyze the key elements of Yushu blooming from environmental regulation to flowering management. Analysis of Yushu flowering conditions The substrate ratio and pot change period use the formula of humus soil + coarse sand + vermiculite (2:1:1), and 1/3 of the soil is reserved when pot changes are made every two years in spring. Laying a 3cm-thick layer of pine needles on the bottom of the basin before changing pots, combined with bone meal as base fertilizer can significantly increase the flowering rate. Collaborative management of light and temperature maintains direct light for 6 hours a day in spring and autumn, and 30% of the sun needs to be shaded in summer. Maintain an environment above 15℃ in winter, and the temperature difference between day and night is controlled within 8℃. The light intensity is recommended to be 20000-35000lux, which can be adjusted and controlled by plant fill light. The "dry and wet cycle method" is used for accurate water and fertilizer supply during the growth period, and the water content of the pot soil drops to 20%. 3-9 Apply slow-release fertilizer with a phosphorus and potassium ratio of 3:1 every half of the month, and apply additional potassium dihydrogen phosphate foliar fertilizer during flower bud differentiation period. Morphological optimization pruning In April every year, 2-3 pairs of leaves are reserved for heavy cutting on the long branches, and the cross branches in the inner chamber are thinned out. Cut off the remaining flower stalks in time after flowering to retain nutrients to promote secondary flowering. After trimming, apply plant ash to the incision to prevent bacteria. Yushu flowering control system The natural flowering period is concentrated from June to September. Annual flowering can be achieved through environmental regulation: flower promotion mode: maintain a constant temperature of 18-25 ° C, extend light to 14 hours/day Sleep mode: control water to once a month, The temperature drops to 10 ° C Emergency treatment to delay flowering: When it is continuously rainy during the flowering period, you can use 0.1% boric acid solution to spray flowers and master the principle of "three controls and one promotion"(water control, temperature control, light control, and fertilizer promotion). Combined with regular pot rotation to ensure uniform light reception, the flowering volume of a single plant can be increased by 2-3 times. A properly maintained five-year-old Yushu can last for more than 120 days.
