Cedar growth habits: light-loving, have a certain shade tolerance, like warm and humid climates, and have a certain cold tolerance. Deep-rooted, drought-tolerant.

The soil requirements are not strict, but it prefers deep and well-drained soils. Avoid stagnant water and be afraid of heat. Weak smoke resistance, sulfur dioxide gas will cause young leaves to wilt quickly.

Cedar growth characteristics:Cedar likes abundant sunshine, is also quietly shade-tolerant, can adapt to acidic soil and slightly alkaline soil, and can also grow on clay loess and barren arid land; But in the waterlogged depression or the groundwater level is too high, it will grow poorly, and even die, it is a shallow root tree species, easy to be blown down by the wind, and the northern winter is windy and cold to take protective measures in advance!

Cedar growth cycle:Pine cuttings can be carried out in both spring and summer. Spring should be before March 20, and summer is best in late July.

In spring, the annual stout shoots of the young mother tree are cut and treated with rooting powder or more or 500 milliliters of naphthalene acetic acid, or at the base of the cuttings, such as 500 ppm naphthalene acetic acid for 5 minutes, it can promote rooting. It is then inserted in a well-ventilated sandy loam soil, watered well and shaded by a double canopy. In summer, it is advisable to select the semi-lignified branches of the current year as cuttings.

In addition to strengthening the shade, it is also necessary to cover the plastic film to maintain humidity. 30-50 days after insertion, callus can be formed, at this time can be used urea and potassium dihydrogen solution of phosphoric acid for extra-root fertilization.

Cedar seedlings can be transplanted after 1-2 years of bed, and the transplanted leaves are carried out in 2-3 months, and the plants need to bring a ball and stand a pole.

Top dressing should be applied 2-3 times during the growth period.

Generally, there is no need to shape and prune, only need to thin the diseased dead branches and the shade weak branches in the close crown of the tree. The seedling stage is susceptible to pests and diseases, especially cataplexy and ground tigers, and other pests include grubs, big bag moths, pine poison moths, pine borers, red wax scales, termites, etc., which should be prevented and controlled in time.

Cedars prefer acidic soils with mild, cool, deep, well-drained soils.

Before sowing, soak the seeds in cold water for 1-2 days, sow seeds after drying, and start germination after 3-5 days, which can last for about 1 month, and the germination rate is 90%.

Annual seedlings can reach 30-40 cm tall and can be transplanted in the spring of the following year.
