How many years after transplanting, can the big tree get rid of its support? How many years does it take to plant trees on a common lawn with an underground garage?

Generally, the support can be dismantled in 2 years, but the actual production can be advanced and postponed according to the tree type; Varieties, growth potential, soil, local climate characteristics, such as fast-growing tree species growing fast, rooting fast, small crown removing the top treatment, strong soil adhesion, no strong storm in the growing season, etc., can be removed after one year according to subjective feelings and practical considerations, on the contrary, two years later is three years.

If you are in the garage, you can plant big trees, but because the soil layer can last for more than three years, you can change the bracket and pull the rope to fix it, and trim the crown in time to ensure the balance between up and down and prevent the wind and rain from lodging.

In short, we cannot generalize. It depends on reality.
