Planting & SoilCâu 44 / 100

a.Left fully intact around the root ball forever
b.Removed only after two years
c.Never touched
d.At least loosened and folded down, with synthetic (non-biodegradable) materials removed from the top of the ball
Giải thích
Natural burlap decomposes, but synthetic burlap and twine do not and can girdle roots, so they should be removed or at least peeled back from the top of the root ball. Wire baskets are cut and folded down after the tree is set. This lets roots grow outward into the surrounding soil.
