There is a particular kind of optimism that arrives in a British garden in late February. The hellebores are still going, the daffodils are pushing through, and the seed catalogues have been pored over more than once. Spring planting is not far away, and the work you do now — while the ground is still cold and the light is thin — will decide how well everything grows once the warmth finally arrives.

The good news is that none of this requires a great deal of money or specialist equipment. It requires a few dry afternoons, a pair of decent gloves, and a willingness to think about your soil before you think about your plants.

Clear the Ground and Take Stock

Start by walking the plot with a notebook and a bin bag. Winter leaves behind more debris than most of us remember: broken stems, fallen leaves matted into corners, collapsed annuals, pots that have cracked with the frost, and the inevitable collection of plastic plant labels scattered across the beds.

• Cut back any dead herbaceous growth you left standing for wildlife, but check hollow stems and seed heads first — insects may still be sheltering inside.
• Clear fallen leaves from around the base of shrubs and roses, where they can harbour disease over the coming months.
• Remove weeds before they set seed. Annual weeds are easy to hoe off now; perennial weeds such as bindweed and ground elder need digging out properly, roots and all.
• Empty pots and troughs, scrub them out, and store them somewhere dry. Clean pots reduce the risk of fungal problems later on.
• Sharpen your secateurs, hoes and spades, and oil the moving parts. Blunt tools bruise stems and make every job twice as hard.

If you have a raised bed or a border that has not been touched for a couple of years, this is also the moment to check the structure. Re-seat loose boards, replace rotten timber, and top up any bed that has settled.

Feed the Soil Before You Feed the Plants

Soil is the real foundation of a productive garden, and spring is the best time to improve it. As soon as the ground is workable — crumbly rather than claggy — spread a generous layer of well-rotted compost or manure across the surface. Two to three inches is plenty for most beds, and you do not need to dig it in. Worms and soil life will pull it down for you, which is far kinder to soil structure than turning everything over.

For heavy clay, which so many of us garden on, aim for organic matter above all else. Compost opens up the structure, improves drainage in winter and holds moisture in summer. For light, sandy soils it does the opposite job just as usefully, helping the ground retain water and nutrients instead of letting them wash straight through.

It is also worth knowing your soil's pH. Simple test kits are inexpensive, and the result will guide what you plant. Most vegetables and ornamentals prefer a slightly acid to neutral range, roughly 6.0 to 7.0. If your soil is very acidic, a light application of garden lime will lift it — but do not lime and manure the same bed at the same time, as they cancel each other out.

Finally, mulch. A layer of compost, leafmould or bark around established shrubs and perennials suppresses weeds and locks in moisture, saving you hours of watering in July.

Plan Your Crop Rotation

If you grow vegetables, crop rotation is the single most effective way to keep plants healthy without reaching for chemicals. The principle is simple: do not grow the same family of crops in the same spot two years running.

Divide your growing space into groups and move them round each season:

• Legumes — peas and beans, which fix nitrogen in the soil and leave it richer for whatever follows.
• Brassicas — cabbages, broccoli, sprouts and kale, which are hungry feeders and benefit from that leftover nitrogen.
• Roots — carrots, parsnips, beetroot and onions, which do best in ground that has not been freshly manured.
• Potatoes — useful for breaking up rough ground, and best kept away from tomatoes to reduce the risk of blight.

Write the plan down. A simple sketch of your beds with last year's crops marked in will save you a great deal of head-scratching next spring, and it helps you spot gaps where a quick salad crop could go.

Start Seeds Under Cover

You do not need a heated greenhouse to get a head start. A bright windowsill, a cold frame or a small unheated greenhouse will do perfectly well for most hardy crops.

In the UK, the last frost date varies widely — from early April in sheltered coastal spots to late May in inland and northern areas. Work backwards from your local date rather than a date on a packet. Tender crops such as tomatoes, courgettes and French beans should not go outside until all risk of frost has passed, and they will need hardening off for a week or two first.

• Sow hardy vegetables like broad beans, spinach and early peas outdoors once the soil is workable.
• Start tomatoes, peppers and aubergines indoors from late February to mid-March, depending on your light levels.
• Label everything clearly with the variety and the date sown. Future you will be grateful.
• Water from below where you can, and keep seedlings in the brightest spot available to prevent leggy, weak growth.

Tidy Paths, Supports and Protection

Give the practical side of the garden an hour of your time before the growing season begins. Re-lay loose paving, top up gravel, and clear moss from steps — slippery paths are a genuine hazard in a wet spring.

Check stakes, obelisks and climbing frames, replacing anything that has rotted. Set up supports for peas, runner beans and tall perennials now, while plants are small and the job is easy. Slug defences are worth putting in place early too, along with netting over any brassicas you plan to plant out.

It is also worth dividing congested perennials and planting bare-root shrubs and roses while they are still dormant. They settle in far better now than they will in May.

Do all of this, and by the time the soil has warmed and the evenings stretch out, you will simply be planting — rather than catching up.
