Professional Tree Services for Gardeners & Landscapers

At Thor's Trees, we love working with gardeners and landscapers across North London and Hertfordshire. We know beautiful outdoor spaces need healthy, well-maintained trees. Our team brings practical tree knowledge to your garden designs, helping you create outdoor spaces that will impress your clients for years to come.

Picking the right trees makes all the difference in landscape designs. We'll help you choose species that not only look great but will actually grow well in your specific soil and space. We recommend statement trees, screening solutions, and everything in between based on what your clients need.

Our team considers factors like ultimate height, soil pH requirements, drainage needs, and light conditions when recommending trees. We plant trees properly too - correct depth, sturdy staking where needed, and proper initial watering regimes. We'll also advise on mulching, fertilising and establishment care to pass on to your clients.

Trees in gardens need regular upkeep to stay looking their best. Our tree surgeons know how to shape and prune to bring out natural beauty while keeping trees structurally sound. We'll help create trees that become real talking points in your garden designs.

We perform crown reductions that maintain natural form, thinning work that improves light penetration without weakening branches, and crown lifts that create usable space beneath trees. All pruning follows British Standard 3998, respecting each tree's biology and growth patterns. This careful approach results in trees that look better year after year and require less remedial work long-term.

Taking on established gardens usually means dealing with older trees that need specialist attention. We'll check existing trees for health issues and spot any that might cause problems or need work to bring them back to their best.

Our arborists conduct detailed tree safety surveys, identifying deadwood, weak unions, decay pockets and other issues invisible to the untrained eye. We use techniques like resistograph testing when necessary to assess internal wood condition. We can help develop multi-year management plans for mature specimens, sequencing work appropriately to minimise stress while gradually improving form and safety.

After 10 years working with gardeners and landscapers, we've learned what matters most. We bring deep tree knowledge without the complicated jargon. We offer straight talk and realistic solutions that make trees thrive in gardens of all types.

We give clear guidance on tree needs and honest timeframes you can build your project schedule around. Our crews work tidily, take care with your existing plants, and leave garden areas clean when we finish.

We can suggest several smaller varieties specifically bred for compact spaces. We look at ultimate height, spread, root behavior, and seasonal interest to find trees that make a statement without outgrowing their spot. We'll also point you toward varieties that won't bully nearby plants for water and nutrients.

Container-grown trees can technically go in almost anytime, but autumn planting gives the best results for most deciduous trees. This gives roots time to settle before summer heat arrives. We can advise on the ideal planting window to fit your project timeline.

Yes. If you're dealing with trees causing too much shade, dropping messy fruit, or growing into structures, we'll assess and suggest practical solutions. Sometimes strategic pruning does the trick; other times removing and replacing with a better-suited tree makes more sense.
