How to cultivate thick roots of primrose

1. Upper basin

In the basin soil, we can add some substances, such as ash powder and other things containing potassium fertilizer, so that the growth process of the root system can be accelerated. The formation of thick roots is to be expected. Generally speaking, Yingchun has a size of four to five years, and its main root length will be thumb thick. At this time, we can carry out the operation of potting. The day before late autumn, or the day before the Qingming Festival, all we have to do is dig up the whole tree, shake the soil loosely attached to the roots, carefully study the growth direction of the roots, and determine the future roots. Cut off all the lateral roots and fibrous roots except those we need. The styling of the branches cut off must be done carefully, so that the styling will remain standard in the future. 2/3 of this major root will be buried in the soil and the rest in the air. The next year, the basin was washed with water to slowly expose the trunk of the buried soil. Washing should be carried out many times, one at a time, the unwanted root should be cut off in time until the desired effect is achieved, so that the main root becomes a bonsai.

2. Select the bar

We can use the method of cutting to cultivate thick roots. The time is relatively broad, and this operation can be carried out in spring, summer and autumn. if the branches we need are semi-Lignified, they can be rooted in about 15 days if they are inserted in sand and soil to keep moisture. If the long branches are buried in the sand and do not need to be carved, they can take root in about 40-50 days, and then separated from the mother plant in the following spring, plants with very thick roots can be cultivated.
