How To Move Shrubs Before Construction

Whether you’re expanding your house or updating your yard, relocating plants can save you money and maintain the beauty of your outdoor space. This process requires careful planning and execution to keep your shrubs healthy. In the above video, This Old House landscape contractor Roger Cook shows the proper technique for moving an evergreen azalea to a temporary location.

Preparing for Moving Shrubs

Before you start digging, gather the necessary tools and materials and assess how much of the root ball you need to preserve.

Tools and Materials

Here’s what you’ll need to move shrubs:

• Burlap sheets
• Plant dolly (can be rented)
• Pointed shovel
• Thick string or twine
• Utility knife
• Watering can or hose

Assessing the Shrub’s Size and Root System

The size of the shrub will determine how much of the root system you need to preserve. As a general rule:

• For larger shrubs, increase the root ball size proportionally.
• For small shrubs, dig up a root ball at least 12 inches in diameter.
• Make sure the root ball is deep enough to include the majority of the roots.

Step-by-Step Guide to Moving Shrubs

Follow these steps to relocate your shrubs safely:

1. Water the shrub thoroughly a day before moving so it’s well-hydrated.
2. Use a pointed shovel to dig straight down just beyond the drip line all around the plant.
3. After cutting the roots, gently pull back on the shovel to loosen the plant.
4. Carefully lift the shrub and place it on a large burlap sheet.
5. Tie together the corners of the burlap sheet to secure the root ball.
6. Use a long, thick string to tie the burlap tightly around the root ball.
7. Dig a shallow hole at the plant’s new, temporary location.
8. Transport the shrub to its new spot using a plant dolly.
9. Gently lower the plant into the hole and water it thoroughly.

Transplanting Evergreen Azaleas

Cook demonstrates how to transplant evergreen azaleas specifically in the video. He emphasizes digging deep around the drip line and securing the root ball properly to prevent damage.

Special Considerations for Large Shrubs

Additional care and preparation are required for larger shrubs. Utilize more help and, if necessary, specialized equipment to handle the increased weight and size.

Additional Tips for Successfully Moving Shrubs

Here are some additional tips for success:

• Consult professionals: When in doubt, consult with professional landscapers who have experience in shrub relocation. Their expertise can save you time and prevent costly mistakes.
• Inspect for pests: Before and after moving, inspect your shrubs for pests or diseases. Address any issues promptly to avoid spreading problems to other plants.
• Label your shrubs: If you’re moving multiple shrubs, label them for proper identification and placement in their new location.
• Monitor weather conditions: Weather can significantly impact the success of shrub moving. Aim for moderate weather conditions to reduce stress on the plants.
• Provide support: For taller or more delicate shrubs, provide support stakes to help them stay upright during their transition period.

Properly Recapturing Roots

The roots are the lifeline of your shrubs, and preserving as many as possible is vital. When digging, make sure to start far enough from the main stem to capture a wide root ball. This typically includes most of the feeder roots needed for water and nutrient uptake.

Quality of Soil in New Location

Soil quality can dramatically affect the success of transplantation. Check that the new location has well-draining soil rich in organic matter. If the native soil is heavy clay or sandy, amend it to improve its structure and fertility.

Caring for Transplanted Shrubs

After moving your shrubs, implement proper care for their survival and growth in their new location. Without this, the effort spent on transplantation could end up wasted.

Watering Requirements

Transplanted shrubs need consistent moisture to establish their root systems. Follow these guidelines:

• Water deeply immediately after planting.
• Continue to water regularly, especially during dry spells.
• Monitor soil moisture and adjust watering as needed.

Overwatering can be just as detrimental as underwatering, so keep a balanced approach to watering.

Mulching and Fertilizing

Mulching and fertilizing help your transplanted shrubs thrive. Apply a 2–3 inch layer of mulch around the base of the plant, keeping it away from the stem. Hold off on fertilizing until the shrub shows signs of new growth. Once established, use a balanced, slow-release fertilizer to promote healthy development.

Pruning for Recovery

Pruning can help transplanted shrubs recover more quickly. Trimming back some of the foliage reduces the demand on the root system and encourages new growth. Do not over-prune, as this can stress the plant further.

Common Mistakes to Avoid When Moving Shrubs

When moving shrubs, be aware of these potential pitfalls:

• Damaging the root system during digging
• Allowing the roots to dry out during the move
• Planting too deeply in the new location
• Overwatering or underwatering after transplanting

Ignoring Seasonal Timing

A common mistake is ignoring seasonal timing for transplantation. Moving shrubs during the wrong season can lead to poor establishment and growth. Research the ideal timing for your specific plant species and climatic conditions.

Failing to Acclimate the Plant

Failing to acclimate the plant to its new environment can result in shock and poor growth. Gradually introduce the plant to its new conditions, checking for the right light, temperature, and moisture levels.

Temporary vs. Permanent Relocation of Shrubs

In some cases, such as the scenario Cook discusses, you may need to move shrubs to a temporary location during construction. This approach requires additional considerations.

Temporary Relocation Tips

Keep the following in mind when temporarily relocating your shrubs:

• Choose a sheltered spot for temporary relocation.
• Make sure the temporary location has similar soil and light conditions.
• Monitor the plant regularly for any signs of stress.

Soil Rehabilitation

Often, the soil in temporary locations may not be ideal. It might be compacted, lack nutrients, or have different pH levels. In these cases, amending the soil with organic matter such as compost or peat moss can improve its condition and help the plant establish more effectively.

Planning for Permanent Placement

A well-thought-out permanent location contributes to the long-term health and aesthetics of your landscape. Think through factors such as sunlight, soil type, and spacing to give your plants the best chance of thriving. When it’s time for permanent relocation, follow the same steps as the initial move.
