Do you remove the metal cage when planting a tree?

When it comes to planting trees, there are several things that need to be considered to ensure their growth and survival. One of these things is the metal cage that can often be found surrounding the root ball of a newly planted tree. But do you remove it or leave it in place?

The purpose of the metal cage

The metal cage, also known as a tree basket, is intended to protect the root ball of a newly planted tree from damage during transport and installation. It is typically made of galvanized steel and can be left in place once the tree has been planted in the ground.

Reasons to remove the metal cage

Despite its intended purpose, there are several reasons you may want to remove the metal cage when planting a tree. One of the main reasons is that the cage can hinder the growth of the tree's roots. As the tree grows, its roots will naturally spread outwards, but the metal cage can prevent this from happening, leading to stunted growth and a weaker root system.

In addition, leaving the metal cage in place can lead to complications down the line. Over time, the metal can rust and deteriorate, potentially causing harm to the tree's roots. It can also become a hazard to people or property if it is not properly maintained and begins to fall apart.

How to remove the metal cage

If you have decided to remove the metal cage from your newly planted tree, there are a few steps you should follow to ensure that it is done safely and effectively. First, use bolt cutters to carefully cut away any wires or other attachments that are holding the cage in place.

Once the cage has been loosened, gently rock the tree back and forth to loosen the root ball from the soil. With a friend or two, carefully lift the tree out of the hole and remove the metal cage from around the roots.

Before replanting the tree, inspect the roots for any signs of damage or tangling, and trim away any damaged or dead roots.

Alternatives to the metal cage

If you are concerned about the potential drawbacks of using a metal cage when planting a tree, there are several alternatives that you can consider. One option is to use a biodegradable tree basket made from materials such as coconut coir or recycled paper.

Another alternative is to plant the tree using the "bare root" method, which involves removing all soil from the roots and planting the tree directly into the ground. This method is often used for smaller trees and shrubs and does not require the use of a metal cage or other protective device.

Conclusion

Deciding whether or not to remove the metal cage when planting a tree ultimately depends on your individual needs and preferences. While it can provide some protection in the short term, it may hinder the tree's growth over time and can potentially become a hazard if not properly maintained.

If you do choose to remove the metal cage, be sure to follow the proper steps to ensure that the tree is not damaged in the process. And if you are unsure about how to proceed, consult a professional arborist for guidance and assistance.
