How should the cycad bonsai shape the leaves? How to dwarf leaves?

I. Blade modeling

It is to bend the leaves inward (downward) to form a small, exquisite and beautiful "sheep horn type" cycad bonsai. The best time for leaf modeling is before the new pinnate compound leaves are put together. Because the new leaves are softer (not lignified) at this time, they are easy to be shaped. Plastic method, with thin copper wire or aluminum wire, or strong and unbreakable nylon wire, the end is fixed on the tip of the tender leaf, the leaf is bent down to a suitable degree, and the other end of the line is fixed at the base of the petiole, leaf by leaf from bottom to top. After about 1 month, all the new pinnate compound leaves have been set and the Lignification bend has been fixed, and the cable has been released gradually. In the process of operation, pay attention to the bending is moderate and consistent, the force is not too large, so as not to damage the broken blade and affect the beauty of the tree.

2. Dwarfing treatment

Cycad leaves grow naturally, tall and straight up to more than 1 meter long, affecting the beauty of bonsai, in order to achieve "sheep horn" shape beauty, must be combined with dwarfing treatment.

1. Monthly fertilizer and water regulation. Cycads were planted in the basin, mainly applied organic fertilizer, fertilized during the growing period, mainly phosphorus and potassium fertilizer, and controlled nitrogen fertilizer to promote steady growth. Watering with slightly moist pot soil is appropriate, especially do not water and fertilize at night, in case the leaves grow too long, continuous rainy weather, to move indoors or cover rain.

2. Growth inhibitor regulation. During the shade bud growth period of cycad new leaves, 0.19% 6 dwarf or 0.07% 0.19% paclobutrazol was sprayed or irrigated to the root, once a week for 3 consecutive times to effectively inhibit the elongation and growth of leaves.

3. Light regulation. In the new leaf growth period, it is necessary to maintain sufficient sunshine and air circulation, and control a certain amount of humidity, increase ultraviolet light, and prevent the excessive growth of leaves. In order to prevent the biased growth of leaves, turn the flowerpot every 3 to 5 days and apply potassium fertilizer to make the leaves tough and undeformed, symmetrical growth, correct shape and beautiful appearance.

Third, prevent yellow leaves

If cycads have the influence of poor management of fertilizer and water, poor structure of pots and uncomfortable temperature, it is easy to yellowing and withering leaves and reduce ornamental value. Measures to prevent leaves from withering and yellowing

The main results are as follows: (1) timely change the basin, renew the culture soil, improve the soil structure and prevent the consolidation and alkalization. Potted cycads generally change pots once every 2 to 3 years. With plant growth and soil aging, small pots change big pots and old soil changes into new ones. Cut off dead and senescent roots, promote new roots and promote robust growth.

(2) apply cake fertilizer, supplement ferrous phosphate (1% concentration of black alum), adjust pH, improve nutrition supply, and prevent element deficiency of yellow leaves.

(3) wrap the stem with grass rope after autumn to prevent low temperature and freezing injury.

(4) properly watering to prevent excessive watering, so as to avoid watering the roots and yellow leaves in the basin.

(5) cut off the senescent leaves at the base, prevent the shade of the plant, promote the light and ventilation, and increase the synthesis of chlorophyll to prevent chlorosis.

(6) to prevent and control diseases and insect pests to ensure normal growth and development.
