Shrub and bush replacement

Whether you are updating a front garden for kerb appeal or removing a diseased hedge, understanding the process and costs involved helps you avoid common pitfalls like "replant disease" or accidental damage to underground services.

What Does the Work Involve?

• Site Assessment: Evaluating the health of existing plants, soil type (clay, loam, or sandy), and checking for signs of pests or honey fungus.
• Clearance: Cutting back the top growth of the old shrub to make the root ball accessible for removal.
• Root Extraction: Digging out the main root system manually or using a stump grinder/mini-digger for larger specimens.
• Soil Preparation: Refreshing the planting hole with organic matter, compost, and mycorrhizal fungi to encourage new root growth.
• Planting: Positioning the new shrub at the correct depth, backfilling, and firming in to remove air pockets.
• Aftercare: Applying a layer of mulch (such as bark or leaf mould) and providing a deep initial watering.

Typical Costs

Prices for shrub replacement in the UK vary based on your location, the size of the plant being removed, and the maturity of the new specimen. The following table provides estimated costs for 2025/26, including VAT.

Cost Factors: The primary drivers of price are the ease of access to the garden and the size of the replacement plant. Buying "instant impact" mature shrubs costs significantly more in both materials and labour due to the weight and size of the planting hole required.

How Long Does It Take?

• Single small shrub: 1–2 hours including removal of the old plant and soil preparation.
• Row of 5–10 medium shrubs: 4–6 hours (a typical half-day booking).
• Large specimen removal and replacement: 1 full day, especially if machinery is needed for the stump.
• Full border rejuvenation: 1–3 days depending on the number of plants and soil condition.

DIY or Professional?

Swapping a small, shallow-rooted shrub for a new one is a manageable weekend task for most homeowners. However, professional gardeners bring essential expertise in identifying soil-borne diseases and ensuring the new plant is compatible with your garden's pH and light levels.

If you are removing a large, established shrub near your home, a professional is recommended to ensure no damage is done to shallow drainage pipes or utility cables.

Professionals also hold a Waste Carrier Licence, which is legally required in the UK to transport garden waste away from your property for commercial disposal.

Choosing the Right Tradesperson

• Qualifications: Look for gardeners with RHS (Royal Horticultural Society) Level 2 or 3 qualifications, or those who are members of the British Association of Landscape Industries (BALI).
• Insurance: Ensure they hold Public Liability Insurance to cover any accidental damage to your property.
• Sourcing: Ask if they source plants from reputable UK nurseries to ensure the specimens are hardened to local weather conditions.

Questions to ask:

• Do you include a survival guarantee for the new plants?
• How do you handle "replant disease" if I am putting a rose back where a rose once was?
• Are disposal costs included in your quote, or are they extra?
• Will you be using a CAT scanner to check for underground pipes before digging?

UK Regulations

• Wildlife and Countryside Act 1981: It is an offence to damage or destroy the nest of any wild bird while it is in use. Major shrub removals should ideally avoid the nesting season (March to August).
• Waste Carrier Licence: Any tradesperson taking green waste away must be registered with the Environment Agency.
• Protected Species: Some hedges or large shrubs may be subject to local Tree Preservation Orders (TPOs) or conservation area restrictions.

Common Problems

• Replant Disease: This occurs when a new plant (typically Roses, Pyracantha, or fruit bushes) is put into the same spot as a closely related predecessor, causing stunted growth.
• Poor Drainage: Digging a hole in heavy clay without "scarifying" the sides can create a "bucket effect," where water sits and rots the new roots.
• Planting Depth: Planting a shrub too deep can rot the stem, while planting too shallow can cause the root ball to dry out and die.
• Underground Services: Many UK gardens have shallow gas, water, or electric lines that can be easily severed by a garden spade or pickaxe.

Frequently Asked Questions

When is the best time of year to replace shrubs?

The ideal window is autumn (October to November) or early spring (March to April). This allows the roots to establish while the soil is moist and before the heat of summer puts the plant under stress.

Can I plant a new shrub exactly where the old one was?

Yes, but you must remove as much of the old root system as possible and refresh the soil. If you are planting roses, use mycorrhizal fungi (like Rootgrow) to prevent replant sickness.

Do I need to grind the stump down?

For most shrubs, digging the root ball out by hand is sufficient. However, for very old, woody species like large Privet or Conifers, stump grinding is the only way to ensure the ground is clear enough for a new plant.

How much water will my new shrub need?

New shrubs need regular watering for their first full growing season. In the UK, this usually means a thorough soaking once or twice a week, more during dry spells, even if it has rained lightly.

Why did my new shrub die shortly after planting?

The most common causes are "root circling" (if the roots weren't teased out from the pot shape), lack of water, or air pockets left in the soil during backfilling. A professional planting service usually prevents these issues.

Is green waste disposal always included?

Not always. Some gardeners will offer a lower "labour only" price and expect you to use your own green bin or compost heap. Always confirm this before the work begins.
