Pruning Guides

Quick Answer Prune most conifers between April and August while they’re actively growing, and only ever cut fresh green growth, never back into old brown wood, since it won’t regenerate. Yew and young Thuja are the main exceptions that can tolerate a hard prune. Always check for nesting birds first, use sharp, sanitised tools, and […]

Quick Answer Sharpen secateurs and shears with a whetstone at a 20 to 25 degree bevel, working only the outer edge. Spades and hoes take a metal file, mower blades come off and go in a vice, never sharpened in place. Clean and oil every tool afterwards, and do a full service each autumn. Sharp […]

Quick Answer Prune apple trees between November and late February while they are dormant. Remove dead, damaged or crossing wood first, shorten this year’s new growth by a quarter, take out any double leaders, then thin congested growth back to an outward facing bud to keep an open goblet shape. Every garden should have at […]

Quick Answer Cut hedges with sharp, clean tools working from the bottom upwards in a sweeping motion, keeping the sides slightly narrower at the top so light reaches the base. Most hedges need trimming twice a year, in spring and late summer, and UK law protects nesting birds, so always check the hedge for nests […]

Quick Answer Lavender usually fails to flower because of too much shade, soil that’s too rich or too wet, or a lack of annual pruning that has let it become woody. Check the season and variety first, then work through sunlight, soil, watering and pruning history. Most causes are fixable within a single growing season. […]

Quick Answer Prune herbaceous perennials in late winter, from January to February, once plants are fully dormant and before new growth begins. Cut ground cover types back to around 5cm, taller perennials to between 6cm and 12cm, and only lightly tidy evergreen herbaceous plants. Leaving the dried stems in place over autumn and winter feeds […]

Quick Answer Prune flowering currant (Ribes sanguineum) immediately after flowering finishes, typically late April to May. Never prune in autumn or winter, since this removes next spring’s flower buds. Remove around a fifth to a third of the oldest stems to ground level each year, or cut hard back to 30 to 50cm for a […]

Quick Answer Prune deciduous berberis such as Berberis thunbergii in mid to late winter while dormant, from December to February. Prune evergreen berberis such as Berberis darwinii immediately after flowering, from May to June. Always wear thorn proof gloves and remove dead wood at any time of year. Transform your berberis from an overgrown, tangled […]

Quick Answer Prune cherry trees in mid to late summer, ideally July to August, and never in winter, since cold, damp cuts invite silver leaf disease and bacterial canker. Remove dead or crossing growth first, thin congested branches, and aim for an open goblet shape, taking no more than a quarter of the canopy in […]

Quick Answer Most garden buddlejas, Buddleja davidii and its hybrids, are pruned hard in late March to mid April, cutting back to 30 to 60cm above the ground since they flower on new wood. Buddleja alternifolia and Buddleja globosa flower on old wood instead, so prune these immediately after flowering finishes rather than in spring, […]
