1. What Are Invasive Climbing Vines?

Just like their name, invasive climbing vines grow vertically, reaching out to higher locations to survive. They look for higher places to get more sunlight. Usually, they will grow in tree canopy or wall. Ivy and crepe are examples of invasive climbing plants that you may find in your garden.

However, they may also create an extreme shade for trees that also need sunlight for photosynthesis. Its invasive growth may cover up these trees and slow down their growth. If you don’t remove invasive plants properly, it may kill your trees slowly.

2. Why Do Vines Climb Up Trees?

Vines climb trees to get closer to the tree canopy and more sunlight. To do an invasive climbing, vines have the ability to connect to surfaces like a tree trunk with sticky pads or adventitious roots, spiral upward with twining stems, and stretch out with tendrils for the journey. However, the development of a tree slows down as a vine reaches its crown.

3. The Reason Why Invasive Vines Could Kill The A Tree

Invasive vines could kill trees in some ways. After a tree is dominated by invasive vines, the tree growth may be inhibited and cause death if you don’t cut the vine up the tree. Here’s some reasons why invasive vines can kill a tree:

Some vines can girdle a tree so tightly that they literally strangle it, preventing it from receiving nutrition.

Blocking Sunlight

Invasive vines also prevent the sun from reaching the tree’s leaves, stopping photosynthesis and ultimately killing the tree.

Reduce Fecundity

In addition, invasive vines decrease a tree’s ability to reproduce since it has limited energy. Additionally, vine-infested trees succumb to death much more quickly.

What Kills Vines Permanently?
