1, the first is to choose grape stumps. Some potted grapes for sale are mostly cut flowers, which lack ornamental value and can only be used as general potted plants. If you just want to make beautiful bonsai, you need to look for older vines.

2. After finding the stump, there is no need to bring soil balls because the vines have developed roots and strong tillering ability. When digging, keep more fibrous roots, cut off the longer main roots, properly keep some branches on the upper part according to the shape, cut off the redundant branches and leaves, and then bring them back to the upper basin.

3. In the embryo cultivation stage, the flowerpots of grape bonsai should be medium-deep pots or ground. After survival, it is necessary to replace it with a shallow teapot, which is conducive to viewing, drainage and ventilation. You can also use the method of shallow basin and high circumference to gradually expose the roots and claws, which can better reflect the health of grape bonsai.

4. The soil substrate for cultivating grape bonsai should be neutral and slightly alkaline sandy soil, and garden soil mixed with some sticky sandy soil can be used as the cultivation substrate, and bone meal, cake residue and animal hoof can be appropriately added as the base fertilizer. If the clods are weakly acidic, they should be adjusted by adding limestone.

5. The shapes of grape bonsai are mostly inclined dry type, bent dry type, lying dry type, water-facing type and cliff type, made of plastic. Generally, according to the original shape of the stump, climbing and pruning are the main methods, supplemented by bud picking and topping to limit the spread of vines; Grape bonsai should not be more than 3 or 5 bunches after hanging fruit, which is beneficial to viewing and does not appear bulky.
