To apply fertilizer:

The main results are as follows: 1. Lily of the valley was fully fermented once in early spring and late autumn, and gradually turned to light after 10-15 days, the room temperature rose to 20 ℃, the bottom temperature was 22 ℃, and increased watering and topdressing. It could blossom after 3 weeks.

Pot soil replacement: Lily of the valley potted plants choose fat and large rhizome buds, 4-5 buds per pot, need to change the pot once a year.

Main points of reproduction: individual plant reproduction.

(1) ramet propagation. There are young buds of different sizes on the rhizome. After the aboveground part withered in autumn, the rhizome was dug up, and each terminal bud was cut off with a section of rhizome to plant, and a new plant could be formed.

(2) the hypertrophic buds can blossom in the following spring, and the small ones need to blossom after one year. Seeds washed from red-ripe berries in autumn can be sowed directly on the seedbed in the open field and germinated the following spring.

(3) ramet propagation was carried out in 2 to 3 years; in late autumn, after the aboveground part of the plant withered, the young buds at the end of the rhizome were dug up for ramet planting.

(4) after the ramet of large bud, it blossoms in the next spring, and the small bud blossoms after the next year.

The first ramet had better leave 6 buds, including both flower buds and leaf buds, and it is better to plant them on deep ploughing and fertile ground. During the period from autumn to early March, the rhizome can be divided into several segments, each with 4 to 6 buds, the wound smeared with some plant ash or sulfur powder, and the hole is covered with soil of about 5 cm.

The first Agricultural Classic editor has already introduced it for you. I would like to know more information, such as "what is the plant of the orchid?" What are the key cultivation techniques for the cultivation of lily of the valley? "wait, you can follow the planting technology channel of our website.
