Step-by-Step Guide to Tidying Up Leyland Cypress

Here's a detailed step-by-step guide to tidying up your Leyland Cypress shrubs and hedges:

Step 1: Assess the Plant

Begin by examining your Leyland Cypress for any dead or diseased branches. Look for areas that are too thick and need thinning and determine the overall shape you want.

Step 2: Prepare Your Tools

Ensure all your pruning tools are clean and sharp. Dull tools can harm the plant and make the job harder.

Step 3: Start with Dead or Diseased Wood

Using your hand pruners or loppers, carefully remove any dead or diseased branches. Cut these back to the main stem or to healthy growth.

Step 4: Thin Out Dense Areas

Look for areas where the foliage is too thick. Use your loppers to thin out these sections, making sure to maintain the natural shape of the plant.

Step 5: Shape the Hedge

Using hedge shears, trim the sides and top of your Leyland Cypress to achieve the desired shape. Aim for a tapered look, wider at the bottom and narrower at the top, to allow sunlight to reach all parts of the plant.

Step 6: Clean Up

After pruning, clean up any debris around the base of the plant. This helps prevent pests and diseases from taking hold.
