Plum trees need enough water during the whole growth period. Especially in summer, if water is insufficient, plum leaves will curl, which will affect flower bud differentiation. If the branches also wither, it means serious water shortage. It is suggested that the potted plant soaking method should be adopted first, and the plants should be put into a tray filled with water or a shallow pot without holes, so that the water can slowly penetrate into the pot from bottom to top until the topsoil on the surface of the pot is wet. At this time, the potted flowers should be taken out immediately. If you plant it in the ground, you should prune it out of season, cut off all the withered parts, water it and shade it for a week. Pay attention to watering in the future, and the water must be "transparent".

First, how to grow red berries

1, soil

Red plum has no special requirements for soil quality, and fertile, loose and permeable soil is the best. Potted plants often use frozen and crisp pond soil mixed with 35% rice bran ash as culture soil.

water

Always keep the basin soil moist. If it won't dry, don't water it to avoid water in the basin. May-June is the period of flower bud differentiation and formation of red plum. To implement the method of "withholding water", let the soil in the flowerpot dry until the old leaves are slightly rolled up, and then water it when the new buds shrink. Repeat this for several times, damage the growth point of new branches, stop elongation to increase flower bud development, and then resume normal watering.

prune

The pruning of bonsai is particularly critical. Plum blossoms germinate only after the new branches are born. Therefore, the flowers should be pruned immediately after withering every year, and the old branches should be cut off, as long as four buds are left. At the same time, pay attention to make the buds grow outward so as to bloom densely in early spring next year. Pruning can also reshape it. Cut off all the parallel branches, long branches and weak branches that affect the beauty of the tree. Combined with turning pots, cut off dead roots and shorten long old roots. And replace 1/2 old soil. Cultivate fertile soil to promote growth.

Step 4 apply fertilizer

Fertilize according to season and growing period. When turning the pot, put some bone meal at the bottom of the pot as its base fertilizer, apply cake fertilizer twice in the middle or late May as topdressing, and then apply it again in early August, that is, doctor's beauty fertilizer. After autumn, continue to fertilize for 2 ~ 3 times, and put it in the greenhouse in winter. Spring Festival can blossom early.

5. Environment

Hongmei likes warmer weather and has excellent cold tolerance. The soil is soft and permeable, and it is a sandy loam rich in nutrients. The soil is too wet and sticky, which is not conducive to drainage and is easy to cause root rot. Therefore, it is best to choose a sunny, dry and well-ventilated place to grow cranberries. It should be placed in a sunny and ventilated place.

The above is the cultivation method of red plum, I hope it will help everyone.
