Horticulture advice

For UK homeowners, this service is invaluable for identifying why specific plants are failing, managing pests and diseases, or planning a garden that looks great year-round. Investing in expert advice early can save you hundreds of pounds in replaced plants and wasted materials.

What Does the Work Involve?

• Site Assessment: Evaluating light levels (aspect), microclimates, and exposure to wind or frost pockets.
• Soil Analysis: Testing pH levels and soil structure (clay, sandy, loam) to determine which plants will naturally flourish.
• Health Check: Inspecting existing trees, shrubs, and perennials for signs of nutrient deficiency, fungal infections, or pest infestations.
• Drainage Evaluation: Checking for waterlogging or overly dry spots that dictate plant selection and soil improvement needs.
• Planting Schemes: Recommending specific species based on the "right plant, right place" principle to ensure long-term growth.
• Maintenance Planning: Providing a bespoke seasonal calendar for pruning, feeding, and dividing plants.

Typical Costs

Prices vary depending on the expert’s qualifications (such as RHS Level 3 or a Degree in Horticulture) and your location. Expect higher rates in London and the South East due to increased overheads.

Factors affecting the final price include the size of the garden, the complexity of the soil issues, and whether you require a simple verbal briefing or a comprehensive written management plan.

How Long Does It Take?

• Initial Advisory Visit: 1 to 3 hours depending on garden size and the number of plants to inspect.
• Soil Testing: 30 minutes for sample collection, with lab results usually returning in 7 to 14 days.
• Planting Plan Design: 5 to 10 hours of off-site work for a standard residential border.
• Remedial Pruning or Soil Prep: 4 to 8 hours for a small-to-medium garden project.

DIY or Professional?

While basic weeding and planting can be done by any enthusiast, professional horticulture advice is essential for complex issues. Identifying specific pathogens or choosing plants for a north-facing, waterlogged garden requires technical knowledge that prevents costly mistakes.

Professional gardeners often have access to specialist nurseries and trade-only varieties that are hardier and better quality than those found in standard retail garden centres.

If your project involves chemical applications (pesticides or herbicides), UK law requires the operative to hold a PA1/PA6 licence. For any work involving large trees, always hire a qualified arborist to ensure safety and compliance with local regulations.

Choosing the Right Tradesperson

• Check Qualifications: Look for RHS (Royal Horticultural Society) Levels 2 or 3, or memberships in the Chartered Institute of Horticulture (CIH).
• Insurance: Ensure they hold Public Liability Insurance (minimum £1 million) to cover any accidental damage to your property.
• Portfolio: Ask to see photos of gardens they have established over several years, not just newly planted ones.
• Ask: "How do you approach sustainable gardening and biodiversity in your recommendations?"
• Ask: "Can you provide a seasonal maintenance schedule if I choose to do the physical work myself?"
• Ask: "Are there any specific pests or diseases currently prevalent in this local area?"

UK Regulations

• Tree Preservation Orders (TPOs): You must check with your local council before any significant pruning or removal of protected trees.
• Conservation Areas: Properties in these areas have stricter rules regarding changes to the landscape and tree work.
• Wildlife Protection: It is an offence under the Wildlife and Countryside Act to disturb nesting birds; significant hedge or tree work should be avoided between March and August.
• Waste Duty of Care: If the gardener removes waste, they must hold a valid Waste Carrier’s Licence issued by the Environment Agency.

Common Problems

• Wrong Plant, Wrong Place: Planting sun-lovers in deep shade or acid-loving plants (like Camellias) in alkaline soil leads to slow death.
• Over-planting: Placing plants too close together for "instant" impact, resulting in poor air circulation and disease within two years.
• Poor Soil Preparation: Skipping soil conditioning before planting, which leads to stunted growth and poor root establishment.
• Incorrect Pruning: Pruning at the wrong time of year, which can remove the following year’s flowers or leave the plant vulnerable to winter frost.

Frequently Asked Questions

When is the best time of year to get horticulture advice?

Autumn and early spring are the best times. Autumn allows you to prepare the soil and plant while the ground is still warm, while early spring is ideal for planning before the main growing season begins.

Do I need a gardener or a garden designer?

A garden designer focuses on the layout, hard landscaping, and overall "look." A horticulturalist focuses on plant health, soil science, and long-term biological success. Many professionals offer both, but check their specific expertise first.

Can a horticulturalist help with a dying tree?

Yes, they can diagnose the issue. However, if the tree is very large or requires climbing equipment, they will likely refer you to a qualified arborist for the actual work.

Is soil testing really necessary?

It is highly recommended for new gardens or if you are seeing widespread plant failure. Knowing your pH and nutrient levels prevents you from spending money on plants that are physically unable to survive in your specific soil.

Will they take the green waste away?

Most professional gardeners will offer this as an extra service. Ensure they have a Waste Carrier's Licence, or consider hiring a council green waste bin to save on disposal costs.

How often should I have a horticultural check-up?

An annual visit in early spring is usually sufficient to adjust your feeding and pruning schedule for the year ahead and catch any emerging pest problems early.
