When Is Arbor Day in 2020? A Step-by-Step Guide to Planting Saplings

Arbor Day is a holiday that promotes the protection of trees and organizes people to actively plant trees and build forests. On Arbor Day, tree-planting activities are organized in many places, so when is Arbor Day in 2020? How should saplings be planted?

1. When Is Arbor Day in 2020?

Arbor Day in 2020 is March 12, Thursday, the 19th day of the second lunar month. Arbor Day is meant to protect and encourage people to plant trees, encourage people to care for trees, and remind people to value trees. Trees play a very important role in human survival and in the Earth's ecological environment.

2. How Are Saplings Planted?

1. Remove the root-ball wrapping: When transplanting trees, to prevent the soil of the root ball from loosening, straw rope or non-woven fabric is generally wrapped around the outside of the root ball, but when the tree is planted in place, the wrapping must be removed in time. For example, if the wrapped straw rope is not removed, after later watering the straw rope will rot and ferment, generating heat or scorching the newly grown fibrous roots, which is not conducive to the tree's survival.

2. Tree hole preparation: The tree hole is an important environment for the rooting of newly transplanted trees. The quality of the soil environment in the tree hole determines how quickly roots form and how quickly the tree survives. The principles for tree hole preparation:

① The width of the tree hole should be about 20 cm greater than the width of the root ball, and the depth should be about 10 cm greater than the height of the root ball;

② Clear stones and other debris from the tree hole;

③ If the soil is too poor, appropriate fertilizer can be mixed into the backfill soil;

④ If the soil is clay, a certain proportion of coarse gravel can be mixed into the original soil to improve soil aeration.

3. Watering after planting the tree: Watering trees after planting is one of the important measures of care. After a tree is planted in place, it generally needs to be watered three times: water once within 24 hours after backfilling the tree hole, water a second time after 7 days, and water a third time after one month. After the three waterings, water according to the soil moisture condition, following the principle of “do not water if not dry, and water thoroughly when watering.”

4. Planting depth of the tree: The planting depth for a tree is generally about 5-8 cm of soil covering the aboveground part of the root ball. Covering with too much soil can easily lead to poor soil aeration, resulting in a low survival rate for the tree later, or relatively smaller leaves.

5. Chemical treatment: For tree species that are difficult to root, during the watering of the rooting water after planting, some rooting-promoting chemicals can be added to help the root system sprout as early as possible.
