January Garden Jobs for Oxfordshire, Berkshire and Buckinghamshire

Why January Matters in the Garden

January is the quietest month in the garden, but there is plenty to do. The garden is dormant, which makes it the perfect time for structural work, pruning and planning. In the Chilterns, January is typically cold (3 to 6 degrees Celsius average) with frosts most nights, but the soil is rarely frozen solid for more than a few days at a time. This means you can work outside on mild days, and the dormant plants will not be disturbed by your activity.

The biggest January mistake is doing nothing. Gardens that are ignored in January become overwhelming in March, when the growth starts and everything needs doing at once. A few hours a week in January sets you up for an easier spring. This guide lists the key January garden jobs for gardeners in Oxfordshire, Berkshire and Buckinghamshire, with specific notes for chalk and clay soils.

Pruning in January

January is the best time to prune many deciduous trees and shrubs while they are dormant. Without leaves, you can see the structure clearly, and the plants will not bleed sap from pruning cuts. Prune on a dry, mild day, and disinfect your tools between plants to avoid spreading disease.

• Apple and pear trees: prune to an open goblet shape, removing crossing branches and any dead or diseased wood. This lets light into the centre and improves fruit quality.
• Wisteria: shorten summer-pruned shoots to 2 to 3 buds. This encourages flowering spurs rather than leafy growth.
• Vines and climbers: prune to control size. Virginia creeper and Boston ivy can be cut back hard.
• Deciduous shrubs: remove dead, diseased and crossing wood. Do not prune spring-flowering shrubs (forsythia, philadelphus) or you will lose the spring display.
• Roses: prune bush roses by half, to an outward-facing bud. Climbing roses: tie in new shoots, shorten side shoots to 3 buds.

Do not prune stone fruits (plums, cherries, apricots) in winter, as it risks silver leaf disease. Wait until April when the sap is rising. See our pruning guide for detail.

Border Work in January

• Clear dead stems and seed heads from perennials (leave some for wildlife if you can)
• Cut back ornamental grasses before new growth starts in March
• Weed on mild days when the soil is workable. Dig out perennial weeds like bindweed and couch grass.
• Dig over new borders if the soil is not frozen or waterlogged. Add compost as you dig.
• Apply a mulch of compost or well-rotted manure to borders. On chalky Chiltern soils, mulch is especially important to build organic matter.
• Lift and divide overcrowded perennials. Replant the outer sections, discard the tired centre.

Lawn Care in January

• Avoid walking on frosty lawns (it bruises the grass and leaves black footprints for weeks)
• Avoid walking on waterlogged lawns (it compacts the soil and damages roots)
• Clear leaves and debris to stop them smothering the grass
• Service the mower ready for spring. Sharpen the blade, change the oil, replace the spark plug.
• Plan any lawn renovation for March or April. See our lawn renovation guide.
• Check for moss. If moss is taking over, plan an iron sulphate treatment for February.

On heavy clay soils in Aylesbury and Didcot, January lawns are often waterlogged. Avoid any work until the water drains. On chalky soils in High Wycombe and Amersham, the lawn may be firm enough to walk on, but still avoid frost.

Structural Work in January

January is the best time for structural work because the garden is dormant and plants are not in leaf. You can see the structure clearly, and access is easier without herbaceous growth in the way.

• Check and repair fences, trellis and arches. Winter storms loosen posts and panels.
• Check garden sheds for leaks. Replace felt roofs before next winter.
• Clean and treat garden furniture. Wooden furniture needs an annual oil or stain.
• Service garden tools and machinery. Sharpen secateurs, loppers and shears.
• Plan new borders, paths and patios for spring. Order materials now to avoid spring rush.
• Check garden lighting. Replace bulbs in outside lights.

See our fencing service for fence repairs and replacements.

Wildlife in January

January is the toughest month for wildlife. Food is scarce, water is frozen, and shelter is critical. A few simple things in your garden can make a big difference.

• Put out bird food and water. High-energy foods like suet and sunflower hearts are best.
• Clean bird feeders and tables to prevent disease transmission.
• Leave seed heads for birds if you have not already cleared them. Goldfinches love thistle and teasel seeds.
• Check hedgehog boxes are dry and insulated. Add dry leaves if needed.
• Plant bare-root hedging for wildlife (hawthorn, blackthorn, hazel). See our hedging guide.
• Provide a shallow dish of water and break the ice daily.

Planting in January

• Plant bare-root trees and shrubs while dormant. Cheaper than pot-grown and establish well.
• Plant bare-root hedges (see our hedge planting guide)
• Plant winter bedding (pansies, violas, cyclamen) if not already done
• Force rhubarb by covering with a forcing jar. Stems will be ready in 6 to 8 weeks.
• Chit early potatoes in a cool, light place. Stand them eye-end up in egg boxes.
• Plant garlic if you missed the autumn planting window. Use varieties suited to spring planting.

Planning in January

January is the month to plan the year ahead. The seed catalogues arrive, the garden is dormant, and you can see the structure clearly. A few hours planning now saves weeks of effort later.

• Order seeds for the vegetable garden. Plan your rotation to avoid building up soil pests.
• Plan new borders and order plants for spring planting. Bare-root plants are best value.
• Plan any hard landscaping projects for spring. Order materials now to avoid the spring rush.
• Review your garden and decide what to change. Take photos to remind yourself what needs doing.
• Buy our Chiltern Guides for lawn care, bedding design and garden design plans.
• Book a garden maintenance schedule for the year. See our maintenance service.

Common January Mistakes

• Walking on frosty lawns. It bruises the grass and leaves black footprints.
• Pruning stone fruits in winter. It risks silver leaf disease. Wait until April.
• Leaving fallen leaves on the lawn. They smother the grass and cause moss.
• Not protecting tender plants. Move tender plants to a greenhouse or wrap them in fleece.
• Not ordering seeds and plants early. Popular varieties sell out by March.

Frequently Asked Questions

Is it OK to plant in January?

Yes, for bare-root trees, shrubs and hedges. Avoid planting pot-grown evergreens in frozen or waterlogged soil. Wait for a mild, dry day.

Should I cut my hedge in January?

Only if it is a deciduous hedge (beech, hornbeam) and there are no nesting birds. Most hedges are best cut in late summer. See our hedge cutting guide.

What if the soil is frozen?

Wait. Frozen soil is impossible to dig and walking on it damages the structure. Use frozen days for indoor tasks: planning, seed ordering, tool maintenance.
