How to Repot and Change the Soil for Jade Tree
As a classic variety of succulents, repotting and changing the soil for jade trees is an important part of maintaining healthy growth. Mastering the correct timing and method not only promotes root development but also gives the old trunk a more ancient and robust appearance. This article will analyze the complete process of repotting jade trees from a practical perspective to help you create a vibrant bonsai art.
One, Core Steps of Repotting Jade Trees
1.1 Key Points for Potting Soil Preparation
Choose a breathable ceramic pot with a diameter about 5cm larger than the original pot and wash it with boiling water for disinfection. The matrix is recommended to use a golden ratio of peat soil: perlite: coarse sand = 3:2:1, mixed with 5% bone meal as a base fertilizer. Special attention should be paid to avoid using sticky garden soil, pine needles can be added to increase acidity, and after mixing, spread it out and expose to the sun for 3 days to sterilize.
1.2 Techniques for Potting Out
Stop watering 3 days in advance to let the soil dry, then invert the pot and tap the pot wall lightly. When encountering root adhesion, a bamboo skewer can be used to circle the pot edge to loosen the soil. Keep 1/3 of the heart-protecting soil and be careful to protect the fine roots when shaking off the compacted old soil.
1.3 Root Pruning Standards
Focus on pruning blackened, rotting roots, parallel entwined roots, and fibrous roots longer than 2/3 of the main root length. The cut should be kept flat and treated with charcoal powder or multi-fungicide powder for disinfection. Keep 3-5 main supporting roots, and the pruning amount should not exceed 40% of the total root mass.
1.4 Key Points for Potting and Care
Place 3cm of ceramsite at the bottom of the pot as a drainage layer, fill the soil to 1cm above the original soil mark after placing the plant. Use the immersion pot method to water until the soil is completely wet and place it in a scattered light area for 15 days of slow seedling. Gradually increase light after new leaves sprout.
Two, Choosing the Best Time for Repotting
The most ideal time is between March and April when the average daily temperature is stable at 18-25°C, as the jade tree ends its dormancy and enters the growth period. Additional repotting can be done in late September of autumn, but a 2-month recovery period should be allowed before winter. Avoid the plum rain season and high summer temperatures, and protect the wounds when repotting on rainy days.
Mastering the spatial and temporal rules for repotting jade trees can effectively avoid the risk of seedling stiffness and supplement trace elements through regular soil replacement. It is recommended to change the potting soil every 2-3 years, combined with pruning and shaping in spring and autumn, to cultivate extremely ornamental jade tree old stumps. During the maintenance process, pay attention to the fullness of the leaves and adjust the maintenance plan in a timely manner.
