How to propagate Arborvitae

How to propagate Arborvitae? Arborvitae is propagated by sowing and rarely by cutting. Now, let's look at these 2 propagation methods in detail.

Sowing propagation method of Arborvitae

Sowing propagation of Arborvitae is in spring before sowing in 40℃ warm water for 12h, and then out into the bag and placed in a warm place, often turn, and keep wet, until more than 50% of the mouth can be sown. Drill or broadcast, after sowing propagation of Arborvitae, covered with soil 1~2cm, and then suppressed, so that the seed and the soil close, in order to facilitate seed germination, on the top of the grass, about 15~20d after sowing unearthed. Spray 0.5%~1% Bordeaux liquid immediately after the seedling is out, and then spray once every 7~10 days. Spraying continuously for 3~4 times can prevent the occurrence of blight. In the seedling stage, Arborvitae can tolerate certain shade and keep proper density. In the case of over-density affecting the growth of seedlings, it is necessary to remove weak seedlings, diseases and insect pests seedlings and double seedlings. Generally, two times of thinning should be carried out when the seedling height is 3~5cm. During the rapid growth period of seedlings, combined with irrigation, topdressing is carried out. Generally, ammonium sulfate is applied 2~3 times throughout the year, and 4~6kg ammonium sulfate is applied to each mu. In cold and windy areas in winter, generally in the soil before freezing water irrigation, and then take buried soil or sandwich fortification of wind barrier for cold, but also covered with grass for cold. The seedling height is 15~ 25cm.

Cutting propagation method of Arborvitae

Cuttage propagation of hard cuttings of Arborvitae is in spring. In the young mother tree selected 1-year-old robust branches, cut 10~12cm cuttings, cut off the lower leaves, inserted into the soil 5~6cm. After inserting, press firmly, water thoroughly, need to put up shade, and often keep the air and soil moist.
