Late spring, early fall,or winter (when the hedges are fully dormant) are the best times for pruning hedges. Don't prune hedges during very hot, dry weather, and prune well before your first frost date. Try to prune on a cloudy day to avoid excessive leaf burn.
If you're wondering when to trim your hedges, it's usually done sometime between spring and summer. You do, however, have to take into account potential nesting birds as nesting season may run from March to August.
We recommend avoiding hedge cutting during the main breeding season for nesting birds, which usually runs throughout March to August each year. This can be weather dependent and some birds may nest outside this period, so it is important to always check carefully for active nests prior to cutting.
You should not cut or trim hedges or trees between the dates of March 1st and September 1st without a derogation. You may only apply for a derogation if you plan to cut hedges before any new grass ley or oil seed rape is sown in the Autumn.
It is important not to cut your hedges too early - wait until the late summer. This will allow your beech to keep its recent flush of new leaves over the winter.
Now and through the summer months is the time to do any major pruning or cutting back of shrubs and trees. With the fast, summer growth rate upon us the plants will regrow and look beautiful for next fall season.
You can cut both the height and width of your overgrown hedge back by up to 50% in one single cut, however we recommend staggering this process over at least two years, preferably more.
The best time to prune is after flowering. If the plant needs to be renovated, or severely reduced, this can be done late winter and early spring just before growth begins. Remove old flowers (deadhead) and cut back to healthy outward facing buds. Remove damaged, diseased, old wood and straggly growth.
New hedges require formative pruning for their first couple of years after planting. Formative pruning is usually carried out in winter or early spring. After this, maintenance trimming is carried out, usually once a year for informal hedges and twice a year for formal hedges.
The best time to rejuvenate large, overgrown shrubs is late winter or early spring (March or early April). Heavy pruning in late winter or early spring will reduce or eliminate the flower display for 2 or 3 years. However, rejuvenation pruning will restore the health of the shrubs.
Generally, the best time to prune or trim trees and shrubs is during the winter months. From November through March, most trees are dormant which makes it the ideal time for the following reasons: Trees are less susceptible to insects or disease.
Reduce the height by up to one-third in April. Thin out the side branches, removing selected branches right back to the trunk but leaving the others intact. This will allow more light and air into the area around the hedge. Mulch and feed in spring to encourage vigorous re-growth.
The rule of thumb for trimming hedges is to cut back no more than a third of the total volume of the hedge at one time. This is enough to encourage new growth in the top half of the plant without causing serious damage to its overall wellbeing.
Trimming a hedge in a wedge shape that is wider at the bottom will make it grow thicker by enabling more even regrowth. Cut back the hedge at the top to steer growth to the sides of your bushes and use organic fertiliser to encourage the plant's development.
Bushes that flower in the summer bloom on growth from the current growing season. These bushes should not be pruned in the summer before blooming, as this would remove the buds that are about to bloom. Prune these shrubs before new growth begins in the spring, either when they are dormant in winter or in early spring.
Winter is usually the best time.
Dormant pruning is usually done in late winter, six to 10 weeks before the average last frost in your area. You can prune shrubs at any time of year if it's necessary—for example, to remove broken branches or dead or diseased wood, or to remove growth that is obstructing a walkway.
Fagus sylvatica - Restoring old beech hedging
In particular a beech hedge can get wider. However it can be brought back into shape quite simply. First, before cutting, it is a good idea to mulch your beech hedge well in the spring. Then, the following winter, you can really go to town.
When should I prune my laurel hedge? Trim your laurel hedge in late spring or early summer as the hedge will produce new shoots very quickly at this time of year to cover up any leaves that are left looking “tatty” after using a hedgetrimmer . You can use secateurs on a small hedge or a hedgetrimmer on a larger hedge.
Frost damages the new, tender growth of Beech foliage. Affected leaves become brown and shrivel quickly. The plant produces new foliage after a couple of weeks and it recovers soon. You just need to wait and not panic.
Many summer-flowering deciduous shrubs can be pruned between February and March; usually those that flower on the current year's growth. Shrubs that need regular pruning include Buddleja davidii, Ceratostigma, Hydrangea paniculata, Lavatera, Leycesteria, Perovskia, hardy fuchsias, and deciduous Ceanothus.
