Answers to your frequently asked questions

When is the best time to seed a new lawn in the UK?

The best time to seed a new lawn in the UK is during early autumn or mid-spring. These seasons provide optimal soil warmth and moisture, promoting healthy germination and root development. Avoid summer unless irrigation is available.

How often should I mow my lawn during the growing season?

Mow weekly between March and October. During peak growth, mow twice a week. Reduce frequency in dry spells and stop mowing when the grass becomes dormant in winter.

What’s the ideal mowing height for a healthy lawn?

Maintain general lawns at 25–40mm. For ornamental lawns, 20–25mm is suitable. Avoid cutting more than one-third of the grass blade at a time to prevent stress.

Should I scarify my lawn, and if so, when?

Yes. Scarify in spring or autumn to remove thatch and moss. Follow with lawn feeding and overseeding to support recovery.

How do I aerate my lawn and why is it important?

Aeration improves drainage and root health. Use a hollow-tine aerator in spring or autumn. Spike aerators are suitable for smaller areas.

What fertiliser should I use on my lawn and when?

Use a high-nitrogen feed in spring and summer. Switch to a potassium-rich fertiliser in autumn. Apply after mowing and before rain for best absorption.

How often should I water my lawn in summer?

Water once or twice a week with a deep soak. Early morning watering helps minimise evaporation. Well-established lawns can tolerate brief droughts.

Can I lay turf all year round?

Yes, provided the ground isn’t frozen or waterlogged. Spring and autumn are ideal for fast rooting. Summer turfing requires regular watering.

What’s the difference between turf and seed for new lawns?

Turf gives instant results and is easier to manage early on. Seed is more affordable and offers more variety but takes longer to establish.

How do I treat lawn moss and weeds effectively?

Apply moss control in spring or autumn. Scarify to remove debris. Use selective weedkillers during active growth and keep your lawn healthy to reduce recurrence.

When is the best time to plant trees and shrubs in the UK?

Autumn and early spring are ideal for planting. Bare root plants must be planted in winter. Avoid summer unless watering is consistent.

How do I improve poor garden soil before planting?

Incorporate compost or well-rotted manure. Consider a soil test to determine pH and nutrients. Mulch annually to maintain condition.

What is the best compost for planting borders?

Use peat-free multipurpose compost blended with garden soil and organic matter. For nutrient-demanding plants, add enriched topsoil or composted manure.

How often should I feed my garden plants?

Feed every 4–6 weeks in the growing season using a balanced or slow-release fertiliser. Avoid overfeeding, which can damage roots.

Do I need to mulch my borders every year?

Yes. Apply mulch in spring or autumn to conserve moisture, suppress weeds, and improve soil structure.

When should I divide perennials?

Divide spring-flowering perennials in autumn, and autumn-flowering ones in spring. Use a spade or fork and water well after replanting.

How can I create a pollinator-friendly garden?

Grow nectar-rich and native plants that flower from spring to autumn. Avoid pesticides and provide undisturbed areas for nesting.

Which native UK plants are best for biodiversity?

Hawthorn, primrose, yarrow, foxglove, and wild thyme are excellent. Native hedges and wildflower mixes also support wildlife.

What is no-dig gardening and is it right for me?

No-dig gardening avoids disturbing soil structure by layering compost or mulch. It reduces weeds and supports soil health—ideal for organic gardens.

How can I test my soil pH and why does it matter?

Use a test kit or send a sample to a lab. Most plants prefer slightly acidic to neutral pH. Soil pH affects nutrient uptake and plant health.

How often should I trim my hedge?

Informal hedges: once or twice a year. Formal hedges: up to four times in summer. Avoid trimming from March to August due to nesting birds.

When is the best time to prune flowering shrubs?

Prune after flowering. Spring-flowering shrubs in late spring; summer-flowering shrubs in late winter or early spring.

How do I prune flowering shrubs correctly?

Remove dead or damaged wood first. Then thin congested growth and shape the plant while maintaining its natural form. Use clean tools and avoid cutting into old wood unless the plant regenerates well.

What’s the correct way to prune a young tree?

Prune during dormancy. Remove crossing or weak branches to establish structure. Avoid removing large branches which could harm the tree’s health.

How can I manage mature trees in a residential garden?

Hire a qualified arborist for inspections. Carry out minimal but effective pruning. Always check for Tree Preservation Orders or conservation rules.

Do I need permission to cut down a tree in my garden?

Yes, if it’s protected or in a Conservation Area. Contact your local authority before undertaking any tree work.

How do I deal with overgrown or neglected hedges?

Cut back gradually over a few seasons. Feed and mulch to support regrowth. Some species tolerate hard pruning; others may not recover well.

What’s the safest way to topiary or shape shrubs?

Use sharp tools, prune gradually, and follow the plant’s natural shape. Avoid heavy cuts into old wood. Feed afterwards to aid recovery.

When should I cut back deciduous hedges?

Late summer is best for maintenance cuts. Formal hedges may also benefit from a midsummer trim. Avoid autumn pruning as new growth may be frost damaged.

When should I install an irrigation system in my garden?

Install in spring or autumn, ideally before planting. Automated systems ensure consistency and save time during hot spells.

How much water do different types of plants need?

Needs vary by species and soil. Lawns and veg need regular watering, shrubs and trees less frequently. Always water deeply and infrequently.

What’s the best method of watering plants during a drought?

Water early morning or evening at the base of plants. Use mulch and water-saving gels. Prioritise young or vulnerable plants.

Are garden irrigation systems environmentally friendly?

Yes. Drip systems are efficient and reduce waste. Combine with rainwater harvesting for maximum sustainability.

How can I make my garden more drought-tolerant?

Choose drought-resistant plants, mulch heavily, reduce lawn area, and group plants with similar needs. Improve soil with compost.

When should I sow vegetables in the UK climate?

Sow hardy crops from February; tender ones from late April. Follow seed packet guidance. Indoors sowing extends the season.

How do I propagate fruit bushes and trees?

Use softwood cuttings in summer or hardwood in winter. Layering and grafting are also effective. Use rooting hormone if needed.

Do I need a greenhouse for successful fruit and veg gardening?

Not essential, but a greenhouse extends the growing season and allows you to grow tender crops like tomatoes and chillies.

What is companion planting and how does it help?

Certain plants benefit others when grown nearby. Marigolds deter pests; beans fix nitrogen. Companion planting supports health and yield.

How can I grow vegetables in a small urban garden?

Use containers, vertical planters, and compact varieties. Raised beds and windowsills can also be productive with good light and watering.

How do I prevent pests in a vegetable garden organically?

Use netting, companion plants, beneficial insects, and organic sprays like neem oil. Avoid monoculture and rotate crops annually.

What’s the best plant food for indoor plants?

Use a balanced liquid feed every 2–4 weeks in spring and summer. Match feed to the plant type—leafy or flowering. Reduce in winter.

How often should I water my houseplants?

Water when the top few centimetres of soil are dry. Most need watering weekly but check individual needs based on light and pot size.

Why are my houseplant leaves turning yellow?

Common causes include overwatering, poor drainage, low light, or lack of nutrients. Adjust watering, light levels, and check for pests.

Do houseplants need feeding in winter?

No. Most houseplants are dormant in winter and don’t need feeding. Resume in spring when growth restarts.

What are the best low-maintenance indoor plants?

Snake plant, ZZ plant, pothos, peace lily, and cast iron plant are hardy, tolerant of low light, and easy to care for.
