Tools You’ll Need

Step-by-Step Pruning Instructions
1. Remove Dead or Diseased Branches:
Start by removing any dead, diseased, or damaged branches. Cut them back to their point of origin.
2. Shape the Columnar Form:
Use loppers to trim any branches that extend beyond the desired columnar shape. Cut them back to a lateral branch or the main stem.
3. Thin Out the Interior:
Thin out the interior of the plant by removing any crossing or crowded branches. This allows light and air to penetrate the center, promoting healthy growth.
4. Reduce Height:
If the plant has grown too tall, you can reduce its height by cutting back the topmost branches. Make the cuts just above a lateral branch or bud.
5. Remove Suckers:
Suckers are shoots that grow from the base of the plant and can detract from its columnar shape. Remove suckers by cutting them back to the ground.
6. Shear for a Formal Look:
For a formal look, you can shear the plant into a precise columnar shape. Use sharp pruning shears to trim the sides and top of the plant evenly.
7. Clean Up:
Once you have finished pruning, remove any debris and dispose of it properly.
