Method of picking heart

The method is to pinch off the top with your fingers when the seedlings grow to the expected height. It is mainly used for herbaceous flowers. It is also used for pruning woody flower seedlings, which can be conducive to the length of lateral branches and make the plant shape beautiful in the future. The method is that when the seedling grows to about 10 cm, remove 1 / 3 or 1 / 2 of the top tip, and the position is 0.5 cm above the axillary bud. It can be carried out many times as required

After most flower seedlings are picked (or cut) at the top of the trunk, the top advantage of the plant will be transferred to the bud under the shear, and 3-4 branches will occur under the shear to replace the growth of the central main branch. Before the transplanting or colonization of grass and flowers, the first coring is to remove the lateral branches at the front end of the central trunk to promote their germination. If you pick them again at the top of each germinating lateral branch after a period of time, more lateral branches will grow, which is called the second coring

General herbaceous flowers, such as a bunch of red, goldfish grass, five color pepper and Catharanthus roseus, can be toppled when the plant height is about 10 cm after the seedlings are settled and survive, so as to promote their multi branching and multi flowering. Another example is the four seasons Begonia, upside down golden bell, chrysanthemum, etc. after the seedlings are planted and survive, they should be picked to promote multiple lateral branches, rich plant shape and increase the number of flowers. However, for some flowers that make the flowers smaller or unable to bloom after picking the heart, such as Impatiens, cockscomb, jiangxila, it is not suitable to pick the heart

Some individual seedlings of woody flowers are cut at the base and changed into clusters. Such as rose, osmanthus, Holly spear, oleander, hibiscus, etc. Some seedlings are cut when they grow to 20-30 cm high, and 3-4 lateral branches are produced. When the lateral branches grow to 10 cm long, they are cut at the top of each lateral branch, and soon a spherical plant with "three trigemines and nine tops" of 9-12 lateral branches will be formed, such as azalea, gardenia, etc< span>
