Planting & SoilCâu 34 / 100
A newly planted tree needs staking. What is the correct staking practice?
a.Allow some trunk movement and remove stakes after the tree establishes, usually within a year
b.Tie the trunk rigidly for at least five years
c.Drive one stake straight through the root ball
d.Wrap wire tightly around the bark
Giải thích
Stakes should support the tree while allowing slight trunk movement, which encourages a stronger trunk and root system. Ties should be loose and use a broad, soft material, and stakes are typically removed after about one growing season. Rigid staking and bare wire damage the tree and create a weak, dependent trunk.
