Fortune Tree Hydroponics Method and Maintenance Guide

1. Introduction to the Fortune Tree

Kapok genus Castanea. The leaves of the rich tree are green in all seasons. The 3-5 strains of young plants are used for the shape of the scorpion, which is chic and beautiful. The plant height of the ground plant is 8-20m, the height of the potted plant is about 2m, and the mini potted plant with a plant height of only 30-50cm is cultivated. Straight, the base is swollen, and the branches are multi-round. Palmately compound leaves, with total stalk; 5-7 leaflets, oblong-lanceolate, ca. 20 cm long, without petiole, entire, subulate, subglabrous. The flower is large, up to 20cm long, yellowish white to pale yellow, and the petals are cracked. April-May (South China) or June-July (East China) flowering, from July to August.

2, rich tree hydroponics method

(1) Method 1

In the spring, the seedlings of the strong soil cultured tree are selected, and the whole plant is dug out, and the soil is removed. The roots of the rich tree are small, careful to operate, and can not damage the root system. It was sterilized with 0.1% potassium permanganate solution for 10 min, and then rooted and placed in a transparent container. Because the rich tree is large, the container should be thick and the root must be embedded in the mouth of the bottle or fixed with a small amount of matrix. Subsequently, inject clean water to 2/3 of the roots of the tree. After that, the water is changed every 2-5 days, and new roots are grown after 2-3 weeks.

(2) Method 2

In the late spring and early summer, the branches of 10 to 15 cm in length were taken, the lower leaves were removed, and the containers were directly inserted into the container, and the branches were filled with 1/3 of the water. Change the water every 2-5 days and spray the branches often. Rooting is slower and it takes 6-9 weeks to grow new roots. Since the base of the hydroponic material formed by the water intercalation method does not expand and the ornamental property is poor, the application is less.

3, Fortune Tree Maintenance Guide

(1) lighting

The rich tree is suitable for high temperature and high humidity weather conditions. The cold resistance is poor, the seedlings are afraid of frost, and the adult tree is resistant to light cream and low temperature of 5-6 °C for a long time. Full-day sunshine is the best, because full-day sunshine can shorten the inter-day, and the plant shape is compact and full. It is best to keep the sun in the growing season of the rich tree. When the light intensity is low, the tree will grow slowly. Special attention should be paid not to shift the plant suddenly from the shade to the strong light, which will cause the leaves to burn and burn the edges, affecting the normal growth and ornamental value of the tree.

(2) watering

The rich tree is more resistant to water and humidity and has poor drought tolerance. It is not suitable for excessive watering to prevent root rot caused by accumulated water, resulting in plant death. Sprinkle water on the leaves every day to ensure that the leaves are green.

(3) Trimming

In the spring, the rich tree should pay attention to trimming the branches in time to promote the new branches of the base of the trunk, so that the new branches can be easily tied and shaped.
