Mature tree planting in Harrogate

Semi-mature trees, avenues, pleached screens and instant hedging, planted while dormant, anchored underground and watered through their first summer.

A sapling takes thirty years to look like anything. Most of our clients would rather not wait, so we plant trees that arrive already grown: four to eight metres tall, from specialist UK nurseries.

Planting a big tree is closer to a building job than gardening. It needs access for the lorry and machinery, a pit dug and improved for the root ball, anchoring that holds it through the first winter's storms, and water through the first summer. That's the work we're known for.

What we plant

  • Avenues and lines of trees along drives
  • Pleached and screening trees for privacy
  • Instant hedging in yew, beech and hornbeam
  • Specimen trees for lawns and parkland
  • Shelter belts for exposed sites

Planting schemes

What big trees can do

Avenues & drives

Matched trees planted in lines along a drive or ride. Matching matters: we choose stock of the same size and form so the avenue reads as one from day one.

Species Lime, hornbeam, beech, oak

Screening

Pleached trees give a hedge on stilts: a screen at first-floor height that blocks overlooking windows while leaving the garden open underneath.

Species Pleached hornbeam, evergreen oak, laurel

Instant hedging

Hedging grown in troughs at the nursery, delivered in metre lengths at full height. Planted in a day, it looks years old immediately.

Species Yew, beech, hornbeam

Specimen trees

A single statement tree for a lawn, a courtyard or the end of a view, chosen for its shape and its colour through the year.

Species Field maple, birch, copper beech

Sizes

How nurseries size trees

Large trees are sold by girth: the trunk's circumference one metre above the ground. Height varies by species, but as a rough guide:

GirthTypical heightGood for
12–14 cm3.5–4.5 mHedgerow trees, larger schemes on a budget
20–25 cm5–6 mAvenues and screening
30–35 cm6–7 mInstant impact, specimen trees
40 cm +7–8 m +Statement trees where access allows

How we plant

From nursery to first summer

  1. Survey

    We check access for the lorry and machinery, the soil, drainage, buried services and how close the trees will be to buildings.

  2. Choose the stock

    We source from specialist UK nurseries and match trees for size and form, which matters most in an avenue.

  3. Dig and prepare the pit

    Pits are dug wider than they are deep, with compacted ground broken up so roots can spread. On clay we make sure the pit won't hold water.

  4. Plant and anchor

    The tree goes in at the right depth and is held with underground guying fixed to the root ball, so there are no stakes or straps to look at.

  5. Irrigation and mulch

    Each tree gets an irrigation pipe at the root ball and a mulch ring to hold moisture and keep the grass back.

  6. The first summer

    We water the trees through their first summer, because that's when newly planted trees fail.

When to book

The right time of year

Big trees go in while they're dormant, from October to March. Book a survey in late summer or early autumn to plant the following winter.

FAQs

Tree planting questions

How big can a newly planted tree be?

Specialist nurseries grow semi-mature trees up to eight metres or more. The right size depends on access for the lorry and machinery, and on the species. We'll advise at the site visit.

When can semi-mature trees be planted?

Root-balled trees go in from October to March while they're dormant; bare-root stock from November to March. Container-grown trees can go in most of the year with careful watering.

Do new trees need staking?

They need anchoring, but not stakes you can see. We use underground guying fixed to the root ball, which holds the tree firm without spoiling the look.

What aftercare do new trees need?

Water, mostly in their first summer, which is when new trees fail. We fit an irrigation pipe at the root ball of each tree and water them through their first summer.

Can you plant a screen to block out a neighbour?

Yes. Pleached trees, instant hedging and evergreens give screening from day one. We'll suggest species that suit the space and the soil.

Thinking about trees?

We'll look at the site, the soil and the access, and suggest what will thrive there. Book over the summer to plant this winter.
