1, trimming and shaping
In order to make the longevity flower grow rapidly and grow into a beautiful old pile of bonsai, it is very important to prune and shape it frequently, because the longevity flower grows rapidly and has strong germination ability, and small lateral buds will continue to grow during the growth process. When there are too many lateral buds on the plant, it is bound to consume more nutrients, resulting in slow growth of all branches. Therefore, we should always wipe off the lateral buds growing at the bottom of plants, and thin the branches that are too dense at the top, leaving only some main modeling branches.
Topping should be carried out during the growth period to make new flower branches germinate on the main branches and increase the flowering amount of pregnant buds. Proper pruning and coring can reduce the consumption of nutrients, make the retained branches grow stronger and increase the flowering amount of pregnant buds.
2. Fertilize to supplement nutrition
Longevity flowers can grow faster and bloom more only if they are well nourished. Therefore, in different growth periods, it is necessary to fertilize regularly and supplement nutrition. During the growth of branches and leaves, more fermented organic fertilizer solution, such as rice washing water and cake fertilizer water, can promote the rapid growth of branches and make them semi-lignified.
Of course, we raise longevity flowers mainly by watching them, so that they can bloom more. Before the plant is pregnant, we can supplement 1 ~ 2 times of potassium dihydrogen phosphate to promote the plant to differentiate flower buds, form flower buds and increase the flowering amount.
Step 3 keep enough light
Longevity flower is a plant that likes sunshine very much. In its growing period, it is necessary to ensure not only sufficient nutrients, but also the growth and development of plants. Only in sunny conditions can this plant thrive and its branches grow stronger.
In the case of long-term lack of light, plants will grow branches and leaves in vain, which will also affect normal flowering. Therefore, in the process of growth and development, we should give it enough light.
Of course, when it is hot in summer, we should give the longevity flowers shade from the sun. Because the longevity flower will be dormant during the high temperature in summer, it is necessary to rest, reduce watering, stop fertilization and do a good job of shading. If placed directly in the sun, it is easy to sunburn the stems and leaves, causing withering.
Step 4 change pots and soil
Longevity flowers that have been cultivated for several years will grow worse and worse, and the flowering amount will also decrease. This is because the nutrients in the basin soil are very scarce, which can not meet the needs of growth, and the basin soil begins to become alkalized and hardened, which seriously affects the normal growth and flowering.
When the longevity flower has been cultivated for 1 ~ 2 years, the pot soil begins to harden and can be replaced in spring and autumn. When preparing culture soil, some humus soil can be mixed into the garden soil, and a small amount of river sand or cinder can be added to ensure that the culture soil is rich in nutrition, loose and breathable, which is beneficial to plant growth.
Longevity flowers at home will immediately change from dormancy to growth. As long as the maintenance of the above aspects is strengthened, it will not take long to develop into a more beautiful old pile of bonsai.
