You can get gardening advice from a wide variety of sources, including the web, books, and even close friends and family.
While some advice may be helpful, others are just plain silly. And sorting out the good from the bad can be challenging, especially if you’re a novice gardener.
When it comes to gardening, some old wives’ tales have been debunked by modern research.
Let’s investigate some of these myths that have been disproven by recent research.
1. Painting pruning cuts
Trees that have had their pruning wounds painted over with tar or pruning paint may appear to have been well cared for.
Some examples of wound dressing materials are latex, shellac, petroleum, and asphalt compounds.
The goal is to prevent decay and other diseases by sealing off the cut surfaces. However, recent studies have shown that wound dressings of this type do not help trees and, in fact, may be quite harmful.
When a stem is damaged or cut, trees form scar tissue or callus at the injury site. This prevents the spread of disease to the trees.
Because they stop calluses from forming, wound paints slow the body’s ability to heal itself. They can actually seal in water, as well as spores and microorganisms that cause decay.
Bleeding cuts, in specific, should never be covered in any way.
It is best to use a sharp tool to make the cut as clean as possible. Make a slanting cut close to the branch’s collar using a clean saw or pruning shears. The rest can be left up to the tree.
If you want to prune your trees heavily, the best time to do it is in the late winter, when the trees are less susceptible to diseases.
