The role of heart-picking: when the seedlings grow to the expected height, pinch off the top tip with your fingers. Mainly for herbaceous flowers. It is also used for pruning woody flower seedlings, which can benefit the length of lateral branches and make the plant shape beautiful in the future.
Heart-picking time: usually when the plant grows to about 8cm to 10cm, the first heart-picking is carried out. The first heart-picking is more important and can control the height of the plant.
Heart-picking method: remove the young leaves and buds at the top. When the seedlings grow to about 10 cm, remove the top tip of 1 big 3 or 1 big 2, 0.5 cm above the axillary bud. It can be carried out many times as required. This is shown in the following figure.
Before the grass flowers are transplanted or planted, the front end of the central trunk is removed to promote its germinating side branches to be called the first coring. If after a period of time, it is picked again at the top of each germinating lateral branch, more lateral branches will grow and called the second coring.
General herbaceous flowers, such as a string of red, goldfish grass, four seasons crabapple, upside down Admiralty, chrysanthemum, Catharanthus roseus, etc., after the seedlings survive, when the plant height is about 10 cm, they can be topped to promote more branches and more flowering. However, for some flowers that make the flowers smaller or cannot bloom after picking the heart, such as impatiens, cockscomb, Jiangxi wax, etc., it is not suitable to pick the heart.
Some woody flowers have single seedlings, such as rose, sweet-scented osmanthus, oleander, hibiscus and so on. Some seedlings will be cut when the seedlings grow to 20-30 cm high, and 3-4 lateral branches will be produced. When the lateral branches grow to 10 cm long, they will be cut at the top of each lateral branch, and a "trigeminal nine-top" spherical plant with 9-12 lateral branches will soon be formed.
