When to Prune
The best time to prune Thuja Green Giants is in the late winter or early spring when the plant is still dormant. This is the optimal time because it allows the plant to focus its energy on new growth and recovery from pruning. Pruning later in the year can cause stress on the plant and inhibit its growth.
Before pruning, it is important to have the right tools on hand. Here is a list of tools you will need:
- Pruning shears
- Hand saw
- Eye protection
- Face mask (optional)
Step-by-Step Guide to Pruning and Shaping Thuja Green Giants
Step 1: Assess the Plant
The first step in pruning and shaping Thuja Green Giants is to assess the plant. Look for any dead, diseased, or damaged branches that need to be removed. Also, consider the desired shape of the plant and identify any areas that need to be pruned to achieve the desired shape.
Step 2: Prune the Dead, Diseased, or Damaged Branches
Using pruning shears, loppers, or a hand saw, cut off any dead, diseased, or damaged branches. These branches can inhibit the growth and health of the plant, so it is important to remove them.
Step 3: Prune to Achieve the Desired Shape
To achieve the desired shape of the plant, prune the top and sides of the plant to the desired height and width. Use pruning shears or loppers to remove any branches that are sticking out or growing in the wrong direction. To create a cone-shaped plant, prune the sides of the plant in a slightly upward angle towards the top of the plant. To create a more formal hedge shape, prune the sides of the plant straight up and down.
Step 4: Create a Tapered Shape
To create a tapered shape, start by pruning the sides of the plant in a slightly upward angle towards the top of the plant. Then, gradually decrease the angle of the cut as you move towards the top of the plant. This will create a tapered shape that is wider at the bottom and narrower at the top.
Step 5: Thin Out the Plant
To maintain the health of the plant and prevent it from becoming too dense, it is important to thin out the plant. Use pruning shears to remove any branches that are crossing or rubbing against each other. Also, remove any branches that are growing towards the inside of the plant, as these can inhibit the growth of the plant.
Step 6: Clean Up
After pruning, clean up any debris that has fallen on the ground. This will prevent any disease or insects from spreading to the plant or other plants in the area. Dispose of the debris properly.
Tips for Pruning and Shaping Thuja Green Giants
Here are some additional tips for pruning and shaping Thuja Green Giants:
Avoid shearing the top of the plant, as this can cause the plant to become too dense and inhibit its growth.
Avoid pruning more than 1/3 of the plant at one time, as this can stress the plant and inhibit its growth.
Always wear gloves, eye protection, and a face mask when pruning, as Thuja Green Giants can cause skin irritation and respiratory issues in some people.
Consider using a ladder or other equipment to reach the higher parts of the plant safely and effectively.
Regularly inspect the plant for any signs of disease or insect infestation, and take action immediately if any are found.
Keep in mind that Thuja Green Giants are fast-growing plants, so you may need to prune and shape them more frequently than other plants.
