How to defoliate potted flowers and landscapes
Answering netizens' questions about the knowledge of landscape making, how to defoliate potted flowers and landscapes. Next, the editor will introduce.
In the cultivation and management of potted flowers and landscapes, timely and moderate defoliation is beneficial to improving the ornamental value of potted flowers and landscapes, extending the ornamental period, promoting branching, leaf growth, and flowering and fruiting. For different types of flowering trees, the timing, amount, and purpose of defoliation, as well as the care before and after defoliation, vary. Therefore, defoliation techniques should be used correctly.
After wintering indoors, jasmines should be placed in a sunny area for about 15 days, combined with potting and replacing soil. Remove all old leaves and prune the branches, removing thin and weak branches from dense areas and shortening all branches. This promotes branching, leaf growth, and overall plant development.
Milans have a strong growth, abundant branches and leaves, and continuously produce new branches, leaves, and flowers. They also form dark green, dull old leaves. Timely removal of these old leaves makes the whole plant's leaves look tender and glossy, preventing mixed leaf colors; it is beneficial for ventilation and light, reducing the growth of diseases and pests; and it reduces nutrient consumption, which is favorable for the growth and development of new branches, leaves, and flower buds.
Wolfberries have a strong vitality, and both their tender leaves and red fruits have good ornamental value, making them excellent materials for landscapes. For potted wolfberries, do not allow flowering and fruiting before autumn. Apply a fast-acting fertilizer around the beginning of autumn, and after a week, remove 80-90% of the leaves. At the same time, prune the branches according to the shaping needs. After 7-10 days, new leaves and flower buds appear together. Once the new leaves unfold, apply cake fertilizer water once a week to make the flowers abundant and the leaves lush, with red fruits filling the branches in autumn.
For species such as elm, catalpa, pomegranate, crape myrtle, Vitex negundo, and ligustrum in tree-stump landscapes, defoliation measures should be taken around the beginning of September or before the exhibition. Ten days before defoliation, apply a fast-acting fertilizer to accumulate nutrients for the germination of new leaves. Use scissors to remove the leaves, leaving the petioles. After 10-20 days, new leaves germinate, not only making the new leaves beautiful and vigorous but also making the leaves smaller, which better showcases the beauty of the branches and trunks.
Crimson maple leaves are bright and eye-catching, but old leaves may become dull or turn green. You can defoliate twice, in June and September, to keep the leaves fresh and red throughout the year and improve ornamental effects.
When using defoliation techniques, do not abuse untested species. After defoliation, special care is needed. After extensive defoliation, water metabolism slows down, so soil moisture should be controlled, slightly on the dry side. Avoid rain during heavy or continuous rain and pause fertilization until new leaves unfold, after which normal care can resume. Flowering landscapes with weak growth should not be defoliated, otherwise, they may accelerate their decline or die.
