Plant vegetables instead of sowing: save valuable weeks in spring

Many amateur gardeners reach for seed too quickly in spring – and lose valuable weeks as a result.

Some vegetables perform far better when planted directly rather than grown from seed.

While the beds are still holding the last of the winter moisture, many gardeners are eager to start sowing at last. However, relying on seeds alone at this point can delay your harvest schedule. Certain vegetables establish much more quickly and reliably when tubers, young plants or so-called asparagus crowns are put into the ground. The difference can easily amount to two to four weeks – and often affects the size of the harvest too.

Why planting rather than sowing saves so much time

A plant's most vulnerable stage is germination. A seed sits in cold, often still-wet soil, where it needs warmth and the right amount of moisture while avoiding rot and fungal disease. With certain crops, you can simply bypass this uncertain stage.

“By planting young plants, tubers or bulbs, you avoid the delicate germination stage and gain an advantage of up to a month on average.”

It makes little difference whether you raise the young plants yourself indoors or buy them from a garden centre. What matters is that they already have roots, are “awake” and can begin growing as soon as the soil has warmed slightly. They therefore make better use of every ray of sunshine than newly germinated seedlings.

The ideal time to start: check soil moisture

However eager you may be, do not plant into soaking-wet soil. If the ground resembles a wet sponge, tubers and roots may rot before they have a chance to establish.

• Turn over a small patch of soil with a spade.
• If the soil sticks heavily to the tool, it is still too early.
• If it breaks apart into a crumbly texture, you can begin.

This straightforward test is more useful than any date on the calendar when deciding whether a bed is ready. Being patient at this stage greatly reduces disease and root damage.

Plant these tubers and bulbs directly

Potatoes: the early starter in the vegetable bed

Growing potatoes from seed is impractical and very slow for ordinary gardeners. Pre-sprouted tubers, on the other hand, give the vegetable bed a real boost. Place potatoes that have already begun to sprout lightly in rows around 8–10 cm deep.

• Spacing between rows: around 60–70 cm
• Spacing within each row: 30–40 cm
• Position the tuber with its visible shoots facing upwards

This gives the tubers plenty of air, helps them dry out more quickly and encourages them to grow once temperatures rise. It reduces fungal problems and allows for early “new potatoes” before summer has properly begun.

Garlic, onions and shallots: small bulbs, major results

Members of the onion family are sensitive to waterlogging and cold during germination. Planting onion sets, garlic cloves and shallots is considerably more dependable than raising them from seed.

“Plant onions and garlic with the tip pointing upwards, covered with only a thin layer of loose soil.”

Avoid firming the soil down too much, so water can drain away freely. Planting too deeply or pressing bulbs into heavy soil increases the risk of rot. When planted correctly, they develop a strong root system early on and mature more reliably.

Perennial vegetables: when seeds are simply too slow

Asparagus: a long-term project with crowns

Asparagus is a classic example of a vegetable for which seed is mainly relevant to professional growers. From seed to the first proper harvest, it can easily take three years. So-called asparagus crowns – one- to two-year-old root systems – are a far more sensible option.

• Dig a deep trench roughly one spade-width across.
• Add a loose, sandy layer to the base.
• Spread out the crowns like small spiders, with the buds facing upwards.
• Refill with loose soil without crushing the roots.

Good drainage is particularly important here. If residual moisture remains in the soil for a long time, the roots suffer – and the bed may remain weak for years.

Plant artichokes as potted young plants

Artichokes need warmth and do not cope well with long, cold germination periods. Sowing outdoors early in the year is slow to succeed in our climate. Potted young plants are much more dependable.

“Planting sturdy artichoke plants with a well-rooted root ball saves weeks of worrying about germination.”

Choose a sunny, sheltered site with deep, nutrient-rich soil. Work plenty of mature compost into the ground before planting. Artichokes remain in the same place for several years, so it is better to prepare the site carefully once than make difficult corrections later.

Prepare the soil gently

Loosen rather than dig over

Many people automatically reach for a spade and turn the entire plot over. Yet this damages fine soil structure and disrupts the microorganisms that maintain fertility. For established planting material, gentle loosening is often enough.

• Use a broadfork, digging fork or cultivator.
• Push it only 10–15 cm into the soil and lift gently; do not turn the soil over.
• Break up large clods by hand.

The soil warms more quickly, water drains more effectively and most soil life remains undisturbed. Your plants will reward this with faster root growth.

Protect young plants from late frosts

Vegetables planted early make faster progress, but they remain vulnerable on cold nights. Even a few degrees below zero can damage fresh shoots. A simple protection routine is therefore worthwhile.

• Keep lightweight fleece covers or thin winter fleece ready.
• Lay them over the beds on clear, frosty nights.
• Ventilate during the day when temperatures are above freezing, so moisture does not build up.

Small polytunnels or old window frames placed on bricks can also create a mini greenhouse. This protects your early advantage without requiring expensive professional equipment.

Higher yields with a well-planned planting schedule

Crops that particularly benefit from planting material

Not every vegetable needs this shortcut; many can still be sown directly with excellent results. However, several crops benefit enormously when planted as young plants or ready-to-plant material:

• Potatoes: quicker tuber formation, lower risk of fungal disease
• Garlic, onions, shallots: sturdier plants, more even harvests
• Asparagus: harvests after only a few years rather than after an “eternity”
• Artichokes: better establishment in cool springs

Planting these crops consistently instead of sowing them brings forward your entire harvest calendar. It also leaves more room and time for typical warmth-loving crops such as tomatoes, peppers and courgettes, which move into the beds later.

How an early start affects the rest of the garden

If you complete your planting tasks in late winter or early spring, you can approach the usual April rush more calmly. Beds for the “early risers” are already occupied, leaving you free to focus fully on more sensitive crops under glass or indoors.

It is also practical that many of these plants are relatively robust and need little maintenance once rooted in. That means less watering and less stress later, when hot weather, holidays and tomato care all arrive at once.

Useful extra tricks for a strong start to the season

Using bed edging, compost borders or dark mulching materials in spring can add a few extra degrees to the soil temperature. Dark surfaces retain more solar warmth and release it gradually in the evening. Tubers and bulbs in particular respond by sprouting more quickly.

Clearly marking rows with string, sticks or stones is also useful. As planted vegetables often emerge earlier than traditionally sown neighbouring crops, beds can quickly become crowded. If you can no longer see what is where, it is easy to tread on young shoots or accidentally hoe into tubers.

Over time, many amateur gardeners adopt a set yearly rhythm: first come the “planting vegetables” such as potatoes, onions, asparagus and artichokes. Next are the usual direct-sown crops, including carrots, radishes, spinach and lettuce. Once you have internalised this order, you can use each growing season more effectively and reliably fill your harvest baskets well before midsummer.
