When to plant a new hedge in Medway, and how long until it's actually doing its job as a screen or boundary.
The naive answer is 'any time', but a hedge planted in July on a dry Chatham Maritime plot will sulk. Get the window and the first two years right, and you get a real boundary in three to five years.

November to February/March: Bare-root planting window
Bare-root hedging should go in while it is dormant, from November to February or March. It costs 60-80% less than container-grown stock and establishes faster because the roots grow directly into the surrounding soil.
In Chatham, Gillingham and Rochester this is the window to get a new hedge in at the lowest cost. On exposed plots around Chatham Maritime and St Mary's Island, the estuary wind makes early root establishment matter even more.

March to October: Container-grown for missed window or instant impact
Container-grown hedging can be planted year-round, but autumn and winter planting still gives the strongest establishment and fastest early growth. Container plants are typically larger at planting, 60-90cm against 40-60cm for bare-root, so they give more immediate visual impact.
They suit summer planting or gardens where consistent watering during dry spells is difficult. If you missed the bare-root window on a St Mary's Island garden with no easy hose run, container stock is the practical choice.

Year 1, spring to summer: Formative pruning: keep it low and bushy
In year one and year two, formative pruning focuses on encouraging bushy growth low down, not on height. Light trims to the leader and sides are the job, rather than a hard cut.
The aim is a hedge that is dense at the base, not a row of bare legs. Letting the leader race away now just stores up a thin, gappy hedge later.
-
Year 2, winter: Second dormant season: repeat the light trim
Year two is still about width and basal shoots, not final height. Keep the same light hand on the leader and sides through the dormant season.
By now the roots have had a full year in Medway soil, and the hedge should be thickening at the bottom. That is the foundation for a working screen.

Year 3: First real privacy starts
A realistic timeframe to a functioning privacy or boundary screen for a typical hedge species, planted well and maintained, is roughly three to five years. By year three a well planted hedge in Medway starts to read as a boundary rather than a row of sticks.
Vigorous species will be ahead of this, yew will be slower. The exact pace depends on the species and the aftercare, not on planting it deeper or feeding it harder.
-
Year 4 to 5: Functioning screen and boundary
By year four or five, a typical hedge species is doing its job as a screen or boundary. It should be dense enough to block sightlines and define the garden edge.
On exposed estuary-side plots around the Dockyard and Chatham Maritime, the salt wind is a factor, but the structure is there. Yew will still be slower, so expect it to lag a year or two behind vigorous species.
Get the planting window right
If you want a hedge that actually screens the garden, plant bare-root between November and February, or use container stock in autumn. Call us to sort the ground and the formative pruning.
