The First Garden Plan: What to Plant Where, for Beginners

The first garden plan for beginners comes down to what to plant where: put the sun lovers, the thirsty crops and the easy wins in the spots that suit them.

The best first garden is one bed of about 1.2 by 2.4 m (4 by 8 ft) in the sunniest spot you have, within hose reach of a tap, filled with six to eight easy plants. It’s small enough to care for in 20 to 30 minutes a day, and big enough to produce real food and flowers in the first season.

This guide is for new gardeners who want a plan they can finish. It brings together the skills in the Plant Growing Guides guides: where to put the garden, how big to make it, how to prepare soil, what to plant and where, and what to do each month. Food-focused gardeners can continue into the vegetables and herbs guides afterward.

Choosing the site: a one-day test

Spend a day watching the space. Note where the sun falls at 9 am, noon and 4 pm, since a spot that’s sunny in June may be shaded by a house or tree in April or September. A good site has:

• Sun: six to eight hours of direct light for fruiting crops. Four hours supports leafy greens and herbs. Under four hours, plant shade-tolerant flowers instead.
• Water: a tap or water butt within reach of a hose, ideally under 15 m away. Hauling cans is the commonest reason beginners abandon a garden.
• Drainage: no standing water 24 hours after heavy rain. If puddles linger, raise the bed.
• Shelter: some protection from strong wind, which dries soil and snaps tall plants. A fence or hedge on the windward side helps, but keep it from casting shade on the bed.
• Convenience: a spot you walk past daily, so you spot pests and harvest at the right moment.

Avoid sites next to large trees and hedges, whose roots will compete with crops for water and nutrients, and avoid low corners where cold air collects and frost lingers. With no ground at all, a sunny balcony, patio or doorstep can host a lively container garden, as covered in container vegetable gardening.

Sizing the bed and comparing garden types

A bed up to 1.2 m wide lets you reach the centre from either side, so you never need to stand on the soil. Standing on soil compresses the air out of it and roots struggle. Leave paths 45 to 60 cm wide, or 90 cm if you want a wheelbarrow through.

Decision rule: if your soil is clay that stays wet, or compacted subsoil that a fork can’t enter, go raised. If it crumbles when squeezed and drains within a few hours, dig in. For hot, dry regions, sunken or level beds with mulch hold water better than tall raised ones. See understanding soil types for a squeeze test.

Preparing the soil

1. Clear the area. Smother grass with overlapping cardboard and 10 cm of mulch for 6 to 8 weeks, or lift the turf. Digging out weed roots is slower than smothering.
2. Loosen the soil. Push a fork in to the full depth of the tines and wiggle it, without turning the soil over. This breaks compaction while keeping soil structure intact.
3. Add compost. Spread 5 to 8 cm of well-rotted compost over the surface and fork the top few centimetres in lightly.
4. Test pH if you can. Most vegetables like pH 6.0 to 7.0. A cheap test kit is enough, and soil pH explained covers adjustments.
5. Rake level. Aim for a fine, even surface in the top 3 to 5 cm for sowing.
6. Mulch the paths. Wood chips or straw suppress weeds and prevent mud.

For a raised bed, a common mix is roughly 60 per cent topsoil, 30 per cent compost and 10 per cent coarse sand or perlite. A mix that’s all compost shrinks within a season and can hold too much water or too many salts. The pots and mix guide covers the container version.

Choosing forgiving plants

Two plants to approach with care in a first year: carrots in heavy soil, which fork and stunt, and cauliflower, which dislikes stress and stalls. Mint should always live in a pot, because its runners will take over a bed. The easiest vegetables to grow guide explains the trade-offs in more depth.

A simple layout that works

For a 1.2 by 2.4 m bed running east to west, think of three bands along its length. Put the tallest plants on the north side so they don’t shade their neighbours (south side in the southern hemisphere). Tomatoes on stakes or a string trellis go at the back, bush beans, courgette and peppers in the middle, and lettuce, radish, herbs and marigold at the front.

• Pair fast with slow. Sow radish and lettuce in the gaps between young tomatoes, and harvest before the tomatoes need the room.
• Give hungry plants room. A courgette needs around 60 to 90 cm, and cramming plants raises humidity, disease and competition.
• Leave a gap for replacement sowings. When radishes finish in May, sow beans or basil in the same space.
• Add a few flowers throughout. They draw hoverflies and bees, and make the garden worth visiting. See companion planting for specific pairings.

A first-year schedule

Dates move with your climate. The seasonal planting calendar shows how to calculate yours from frost dates and soil temperature. In hot dry regions, move most of the cool-season row to autumn, and in humid tropical areas plan around the rainy and drier seasons.

The weekly routine

• Every few days: check soil moisture 5 cm deep. Water deeply when the top 3 to 4 cm is dry, not a little each day (see watering plants the right way).
• Weekly: pull small weeds, look under leaves for pests, tie in climbers, and harvest. Regular picking encourages more production.
• Monthly: top up mulch, and feed container plants and heavy feeders such as tomatoes and courgettes.
• Each season: add compost and record what grew well.

A short journal, even three lines a week with sowing dates, varieties, weather and yields, becomes your most valuable gardening tool by year two. When leaves change colour, reading plant signals helps you decide whether to act.

How your first garden plan fits sun, soil and water

Six to eight hours of sun feeds tomato, pepper and courgette, while lettuce, spinach and kale tolerate partial shade and bolt less in a heatwave. A raised bed improves drainage in clay and warms the soil temperature earlier in spring, so you’ll sow sooner. Compost feeds the bed and holds moisture, and mulch reduces weeds and protects the roots from drought.

A hose bib or watering can near the bed saves you effort, because plants that are hard to reach get watered less. Companion planting helps too: marigold repels some pests and basil supports tomato growth, so a small mixed bed controls trouble better than a single row. Where should you start if the plot is large? Choose a bed of about 1.2 by 2.4 metres, because you can reach the centre from both sides and avoid compacting the topsoil. The RHS suggests starting small and expanding once the first season has taught you what thrives.

What to plant where, and why it matters

Tomato, pepper and courgette need 6 to 8 hours of sun and warm soil temperature, so they belong on the south side of the bed where taller sweetcorn can’t shade them. Lettuce and spinach tolerate partial shade and bolt less often when a trellis of bean cools them in July. Carrot and radish need loose loam without stones, so you should keep them away from freshly dug clay that holds water and blocks the roots by 5 cm or more.

Basil attracts hoverfly and repels whitefly beside tomato, so a few plants at the bed’s edge protect your main crop without spraying. A hose near the bed improves your habits, because tomato and lettuce that are hard to reach get watered less. Mulch holds moisture and reduces weeds, and compost 5 cm deep feeds the bed and supports steady growth. Slug and snail damage young lettuce, so a copper tape or beer trap controls them before the first leaves open. Your extension service can confirm frost dates for the 20 weeks of the growing season, and the vegetable garden starter guide needs only a weekend to follow.

If you only have a 2 by 3 m bed, you’ll get the best return from three crops that tolerate beginner mistakes, such as radish, lettuce and courgette, and your own notes will tell you what to repeat.

Common mistakes and what causes them

Loss is normal. Every gardener loses plants, and one failed crop teaches more than a flawless one. Note the cause, replant in the gap, and move on.
