How to raise poplar seedlings?

Seeding and propagation: Poplar seeds are small, and the capsules will crack when mature, so the seeds are collected by ear or ground. Seeds are easy to lose germination ability, so they should be sown with the harvest. Sowing seedlings on sandy loam soil containing humus.

Cutting propagation:

First, select high-quality seed strips, select annual cutting seedlings, and it is appropriate to use the middle and lower parts of first-class seedlings and second-class seedlings as seed strips. Third-grade seedlings can not be used as second-grade seedlings, and the parts with poor lignification at the tip and seedlings with pests and diseases can not be used as seed belts.

2. Cutting length and treatment 16cm- 18cm, bud opening distance 1cm. Cut and bundle the cuttings and soak them in clear water to ensure that the cuttings do not lose water.

III. Cutting Time, Method and Density

1. Cut-off time: 1 till early March.

2. Cutting method: insert directly, and insert the cutting into the soil for 2/3-3/4. Be careful not to insert it backwards. After insertion, tighten the soil and water it once.
