The garden in November

November is the heart of the bare-root season and the last good month for planting before winter. It's also when frost protection moves from forecast-watching to routine.

The garden is quieter, but it's a good moment for the jobs that make next year easier: planting, mulching, cleaning tools, and giving houseplants the winter conditions they need.

UK and similar cool temperate climates. Frosts are regular now almost everywhere; only mild coastal gardens stay largely frost-free.

AT A GLANCE

Spotlight: planting a bare-root tree or rose

Bare-root plants are dug from the field while dormant and sent without soil. They are cheaper than potted plants and, planted between November and March, usually establish better.

As soon as they arrive, soak the roots in a bucket of water for an hour or two. Dig a hole wider than the spread of the roots but no deeper — the old soil mark on the stem should end up at ground level; roses are the exception and go in with the graft union just below the surface. Loosen the soil at the bottom and sides, spread the roots out, and backfill gradually, shaking the plant gently so soil fills the gaps. Firm with your foot, water well even in winter, and mulch.

Trees need a short stake on the side of the prevailing wind, with a tie that doesn't cut into the bark. If the ground is frozen when your plants arrive, 'heel them in' — lay them in a shallow trench and cover the roots — or keep them in a bucket of damp compost in a cool shed for a few days.

Jobs this month

Bare-root planting

Bare-root plants are cheaper, come in a wider choice and establish better than potted ones. Plant them as soon as possible after they arrive; if the ground is frozen, heel them into a spare bed or a bucket of compost.

Winter protection

Borderline plants survive cold far better when their roots are dry. Protect the crown and keep pots off the ground.

Houseplants in their winter mode

Some houseplants flower only if they get a cool, dry rest in winter. Others just need less water and more light.

Give clivias a cool (around 10°C), fairly dry rest for about eight weeks. Clivia

Tools and structures

Clean tools rust less and spread fewer diseases. It's also a good time to clean pots and greenhouse glass to maximise winter light.

Questions

Can I plant in November?

Yes — it's one of the best months for bare-root trees, roses, fruit and hedges, as long as the ground isn't frozen or waterlogged.

How do I protect plants in pots from frost?

Raise pots off the ground, group them against a sheltered wall, wrap the pot in hessian or bubble wrap, and cover the plant with fleece on the coldest nights.

Why won't my clivia flower?

It usually needs a cooler, drier winter rest. Around eight weeks at about 10°C with little water, then normal care once the flower stem appears.
