Plant tubers and young plants in March instead of sowing vegetables

If you are eagerly awaiting warmer March days, you will often be itching to get started: sow at last, get growing at last. Yet this is precisely when a different approach pays off. Certain vegetables yield more, establish themselves more reliably and get underway weeks earlier when planted as planting stock, tubers or young plants rather than laboriously raised from seed.

Why planting is often wiser than sowing

Up to four weeks’ head start in the vegetable bed

Every sowing method has the same vulnerable point: the delicate germination stage. Seeds need the correct temperature, enough moisture without becoming waterlogged, and protection from hungry pests – and even then, success is not guaranteed. Pre-sprouted tubers, sets and young plants allow you to bypass this risky stage entirely.

“Using planting stock instead of seed saves two to four weeks and greatly improves the likelihood of a plentiful harvest.”

Plants raised in advance and tubers already contain stored energy and have begun forming roots. As soon as the soil provides a little warmth, they start growing rather than first having to germinate. This has an immediate effect on the timetable: earlier flowering, earlier harvests and more dependable crops.

The key starting point: choosing the right moment for the soil

Despite all the anticipation, the soil must no longer be a sodden mess. Planting into wet ground risks rot, fungal diseases and poorly rooted plants.

• Take some soil in your hand: if it forms a sticky lump, it is too early.
• If it breaks apart easily, you can begin.
• Try a tool: if heavy clay sticks all over the spade, wait a little longer.

Once the ground has dried sufficiently while still retaining some moisture, conditions are almost ideal. At that point, every trip to the garden is worthwhile – particularly for the crops below.

These tubers and bulbs should go into the ground early

Potatoes: tubers rather than seed – a fast track to an early vegetable bed

Growing potatoes from seed is a project for breeders, not everyday gardeners. Pre-sprouted seed potatoes, by contrast, are straightforward and dependable. Placing them in rows now gives them a substantial early advantage.

Key planting points:

• Use pre-sprouted tubers; short shoots measuring 1–2 cm are ideal.
• Make furrows around 10–15 cm deep.
• Leave approximately 60–70 cm between rows and about 30–35 cm between plants within each row.
• Cover them only lightly with soil, then gradually earth them up later.

The seed tuber gives each young potato plant a powerful initial boost. Growth is quick and robust, often with fewer fungal issues because plants are already well established by the time the weather changes.

Garlic, onions and shallots: small sets, considerable results

For alliums, it is worth choosing onion sets and garlic cloves rather than sowing seed. They create a strong root system more quickly and make the best use of spring moisture before summer heat arrives.

“Planting garlic cloves and onion sets directly gives you strong plants – and means far less pricking out and thinning.”

Plant them correctly as follows:

• Always position the pointed end of the bulb or clove upwards.
• Plant only deeply enough for a thin layer of soil to cover it.
• Soil must be loose and well aerated; waterlogging quickly causes rot.

The plants then root steadily, if gradually, into the warming soil. The result is large onions, flavoursome bulbs and less pressure during high summer.

Perennial crops: planting makes the difference for these vegetables

Asparagus: gain years by planting crowns

Raising asparagus from seed may sound appealing, but it is painfully slow. Several years pass before the first worthwhile harvest. Planting asparagus crowns instead of seeds saves a great deal of time.

A successful start involves:

• Creating a deep, loose planting trench and improving it with sand or compost.
• Setting the crowns slightly raised on a small ridge, spreading their roots out like a fan.
• Covering them with only a thin layer of soil, then topping this up over the coming months.

Asparagus hates waterlogged ground. A well-drained position determines whether it succeeds or fails. Once it has established, the plant rewards you with harvests for more than a decade.

Globe artichokes: young plants instead of temperamental seed germination

Globe artichokes thrive on warmth and consistency. Germination from seed can be erratic and rarely suits our spring weather. Planting ready-grown young plants or offsets, meaning divisions taken from the parent plant, removes much of the difficulty.

“With strong young globe artichoke plants in the vegetable bed, you skip the most delicate stage – and enjoy decorative, edible buds much sooner.”

Globe artichokes require:

• a sunny, sheltered site;
• plenty of organic matter in the soil, such as mature compost;
• adequate room – roughly 80 to 100 cm per plant.

Giving these hungry plants plenty of compost at planting time provides a sound foundation. They then cope better with fluctuating temperatures and grow strongly.

How to prepare the soil gently for planting

Loosen rather than dig: kinder to soil life and roots

Deep digging damages earthworm channels, fungal networks and the soil’s fine structure. For most spring tasks, gently loosening the top layer is entirely sufficient.

Suitable methods include:

• Using a cultivator or a single-tine ripper, working only a few centimetres deep.
• Clearing planting areas of large clods and stones.
• Working mature compost into the surface rather than burying it.

This lets the soil warm faster, improves drainage and gives new roots airy passages to follow. It encourages living, crumbly soil – the best foundation for sturdy plants.

Protection from late frost: modest effort, major benefit

March can feel spring-like during the day before temperatures drop to a light frost overnight. Newly planted potatoes and emerging alliums are especially sensitive to this.

These simple protective measures cost little, yet can prevent frost damage that might set entire beds back by weeks.

A calm route through the busy gardening season with smart planning

Strategic planting that pays off throughout the year

Planting tubers and planting stock now reduces the pressure of the usual April rush in the garden. While tomatoes, peppers and squash take centre stage later on, potatoes, onions, asparagus and globe artichokes will already be growing steadily.

“Early plantings form the backbone of the vegetable garden – they work reliably in the background while you focus on more delicate crops later.”

Early potatoes provide the first harvest pleasures before the summer holidays. Onions and garlic stock the larder and kitchen while other crops are still developing. Perennial vegetables such as asparagus and globe artichokes deliver regular yields for years with relatively little follow-up work.

Common mistakes that eliminate the planting advantage

To ensure the plan really works, it is worth watching for these frequent pitfalls:

• Soil that is too wet: this causes rot, particularly in garlic and onion sets.
• Planting too deeply: this weakens new growth, especially in alliums.
• No crop rotation: never grow potatoes and onions in the same place for several consecutive years.
• Spacing plants too closely: this encourages fungal diseases and weak plants.

Keeping these points in mind lets you make full use of the real benefit of planting: fewer losses and greater yields with manageable effort.

This approach is particularly worthwhile in small urban gardens or on balconies: begin with robust seed potatoes in a bag, onion sets in containers or a single globe artichoke plant in a large pot. It creates the sense of an “active” garden early in the year, while the main sowing and pricking-out work is only just beginning.

This planting strategy is especially suitable for beginners. It is more forgiving than sowing, needs less specialist knowledge and still delivers noticeable success. Anyone who has seen how much more reliably certain vegetables begin from tubers, sets or young plants will no longer automatically reach for a packet of seeds first each spring.
