New hedge aftercare: the two-year establishment plan.
Getting the plants in the ground is the easy part. More new hedges die in their first summer than in any subsequent decade, and on Wingham's freely draining chalk and Thanet Sand soils, the margin for error is thinner than most guides suggest.
This guide picks up where bare-root native hedge planting leaves off. The hedge is in. The guards are on. What now?
1. Watering: the first-summer priority
On free-draining soil, neglecting watering in the first summer kills more new hedges than anything else. Wingham sits in one of the drier parts of Kent, receiving around 725 to 750 millimetres of rain a year, and most of that falls outside the growing season. A bare-root hawthorn or hornbeam planted in November has had five months of winter rainfall to settle before a dry East Kent July arrives. One planted in March has had weeks.
The routine for year one: apply at least 10 litres per metre of hedge, twice a week, from May through to September during any dry spell. Water slowly at the base so it penetrates rather than sheeting off compacted ground. A watering can works for a short run; for anything longer than 15 metres, a garden hose on a gentle setting is faster and gets the soil properly wet rather than just damp at the surface.
Chalk-side gardens (west toward Adisham and Bekesbourne, up on the higher, drier ground above the A257) need more attention. The chalk here is Seaford Chalk with thin topsoil above it, strongly alkaline and free-draining. In a dry July, the first spade-depth goes bone dry within a day of rain. Gardens on this ground may need watering every four to five days rather than twice a week once temperatures climb. If the soil half a metre from the hedge row cracks and goes powdery, that is a chalk-side drought signal: water immediately and increase the cadence.
Thanet Sand gardens (east toward Ash and Staple) are also free-draining but hold a little more soil structure than chalk. Twice-weekly watering through dry spells is usually enough, but the ground still needs checking: Thanet Sand goes from damp to bone dry more quickly than a clay loam in the same weather, and a hedge line planted along a sunny south-facing boundary dries out faster still.
Little Stour valley gardens (around Wickhambreaux, Ickham and Preston) face a different first-winter risk. Lower ground beside the Stour can be slow-draining in a wet November and December, and new hedge plants sitting in waterlogged soil for weeks will struggle. If the planting trench collects standing water after heavy rain, a shallow drainage channel cut along the hedge line before planting helps enormously. By the following summer, even Little Stour valley gardens dry out significantly, and the first-year watering routine matters here just as much as on chalk.
2. Weed suppression
Grass and weeds competing for moisture are the second most common cause of failed establishment. Keep a 45-centimetre weed-free strip either side of the hedge line for two full growing seasons. That is 90 centimetres of bare or mulched ground in total, centred on the plants.
On chalk near Adisham and Bekesbourne the competition effect is magnified. Shallow chalk topsoil holds so little moisture that a strip of couch grass or annual weeds either side of a young hawthorn can draw what little water there is before it reaches the hedge roots. This is where the 45cm strip matters most, and where the temptation to let the grass grow back quickly is most dangerous in the first summer.
Hand-weeding or careful hoeing is the right approach within 30 centimetres of the stems. Residual herbicides can damage shallow roots on sandy or chalky soils where there is little organic matter to buffer them, so avoid those near young plants even if you use them further back.
3. Mulching
Apply a seven to ten centimetre layer of bark chip or wood chip along the full hedge line, kept five centimetres back from the stems. Mulch does three jobs: it suppresses weeds, retains moisture, and insulates roots against temperature extremes. That last point matters in both directions: summer heat on a chalk-side garden near Adisham, and the overnight February frosts that settle in the Little Stour valley at Wickhambreaux and Ickham every winter.
Refresh the mulch layer in late February or early March of year two, before the growing season starts. The layer will have broken down over winter. Topping it back up before the dry season costs an afternoon and saves considerably more watering effort through summer.
On chalk-side gardens, mixing spent mushroom compost or well-rotted garden compost into the surface under the mulch layer adds some organic matter that chalk topsoil is inherently short of. Avoid deeply acidifying materials (pine bark, peat) on chalk: they make no difference to the pH at garden-compost quantities, but there is no benefit either, and they are wasted resource on already alkaline ground.
4. Guards and protection
Tree guards or spiral guards on each plant protect stems from rabbits, deer and accidental strimmer damage during the establishment years. They also create a slightly warmer, more humid microclimate around the stem in year one, which helps bare-root plants break dormancy more reliably.
Remove individual guards once the stem has reached finger-width and is clearly established, or at the latest by the end of year two. Guards left on too long can harbour disease, restrict stem development and, on the sheltered ground near Wickhambreaux where humidity is higher, create conditions that favour fungal problems in the base of hawthorn and blackthorn stems.
Stakes, if used, should come out after 18 months. A new hedge plant that has coped with moderate wind movement will develop a stronger root system than one kept rigidly staked through two winters.
5. Feeding in year one
A balanced slow-release fertiliser applied in March of the first growing season supports establishment without pushing excessive soft growth. Keep the nitrogen content moderate: high-nitrogen feeds in late summer promote lush new tissue that is vulnerable to the late frosts that can run into April in the Little Stour valley in a cold spring.
On Thanet Sand toward Ash and Staple, where the soil is inherently low in nutrients, this first-year feed matters more than on chalk, where alkaline conditions limit availability but base-nutrient levels are often adequate for basic establishment. Do not over-feed: a newly planted hedge needs steady, modest nutrition, not a push for rapid growth in year one.
See the feeding and mulching guide for the full established-hedge routine from year three onwards, including the soil-specific approach for chalk near Adisham versus Thanet Sand east toward Ash.
6. What not to do in year one
Do not cut. A new hedge plant is building root mass during its first growing season. Cutting the leaders triggers lateral branching, which the plant cannot sustain reliably while establishing in free-draining East Kent soil. The inclination to tidy things up in the first summer is understandable, but the single best thing you can do is leave the top growth alone and put your effort into watering and weed suppression at ground level.
The bird-nesting window
When the time comes for a first formative trim in autumn of year two, the legal window applies. The Wildlife and Countryside Act 1981 (Section 1) makes it an offence to damage or destroy an active wild bird's nest. The nesting season runs 1 March to 31 August. The safe window for hedge work is September to February. In a Wingham garden, blackbird, robin, wren, dunnock and long-tailed tit are all likely to be active in even a young hawthorn hedge by its second spring. Check for nests visually before any cut, and if in doubt, wait. For species-rich hedges near the Little Stour at Wickhambreaux or Ickham, also check the dormice guide: hazel dormice, protected under WCA 1981, can establish in new woody habitat faster than most people expect.
7. The year-two formative cut
In September to October of year two, a light formative trim shapes the hedge for the decades ahead. This is not a hard cut: tip the leaders back by 10 to 15 centimetres and trim the sides to a slight inward taper, wider at the base than the top. The A-profile shape that lets light reach the lower stems is exactly the principle covered in the trimming technique guide.
Safety on the first cut: wear eye protection and gloves. Hawthorn and blackthorn stems from a two-year-old plant are genuinely sharp. If using a powered trimmer, fit an RCD adaptor on any extension lead. Check the hedge base for wasp nests before starting, particularly in a warm September, and for bramble growth that has crept in under the guards during year two.
Do not cut hard in year two. The aim is to encourage branching and density, not to impose a finished shape. A hedge allowed to grow freely for two years before its first cut will be denser at the base and more resilient than one cut back to a stub height immediately after planting. From year three the hedge is broadly established and the normal species-specific cutting calendar applies. For the most common Wingham species, the East Kent hedge calendar gives the full year-round picture.
If the hedge sits inside the Wingham Conservation Area and any stem has reached 75mm diameter at 1.5m height, a Section 211 notice to Dover District Council is required before the formative cut. Wingham's historic core is covered; check whether your plot falls within the area before booking in the cut. The Section 211 guide walks through what to file and how long to allow.
