What is behind the hype around old vegetable varieties?

Grandparents’ gardens often bring back memories of crooked carrots, enormous squashes and tomatoes that genuinely tasted of tomato. These very “old varieties” are now making a strong comeback – in allotments, suburban gardens and even on balconies. For many amateur gardeners, the period around mid-April marks the moment to put these trusted classics back into the soil.

Why old vegetable varieties are suddenly filling beds again

For a long time, the supermarket standard was clear: everything the same size, the same colour and perfectly round. Industrial farming favoured varieties that produced high yields, travelled well and looked as uniform as possible. Flavour, fragrance and resilience were often lost in the process.

Old vegetable varieties, also frequently called “landraces” or “farm-saved varieties”, continued quietly in the background of this development. Gardeners swapped and passed on seeds, preserving lines that might otherwise have been forgotten. Today, this is exactly the seed stock attracting renewed attention.

Old varieties represent hardy plants, intense flavour and genuine diversity rather than uniform vegetables.

Three factors are driving the trend:

• Hardiness: Many of these varieties are adapted to local conditions and cope better with heat, cold or disease.
• Less chemical input: Choosing hardy varieties often means that less fertiliser and fewer plant-protection products are needed.
• Flavour: Juicy tomatoes, flavoursome beans and sweet squashes – old varieties often offer a noticeably stronger taste.

There is also an emotional element. People grow what their grandparents once sowed. It creates a sense of connection, brings pride and gives a garden its own history.

Which old varieties are particularly worthwhile in mid-April

For many areas, the middle of April is a turning point: soil begins to warm up, days become longer and the risk of frost falls – at least in milder locations. This is when many gardeners reach for packets of old varieties.

Four reliable classics to grow now

• Old tomato varieties – Fleshy oxheart tomatoes, yellow pear tomatoes and deep-red, almost brown varieties all offer intense flavour and unusual colours. They are ideal for sunny balconies or sheltered beds.
• Climbing beans – Once commonplace, they now seem almost exotic. They grow upwards, take up little ground space and are therefore perfect for small gardens. Many heritage varieties crop heavily over a long period.
• Ancient squashes – From long-storing muscat types to floury culinary squashes, old lines are often remarkably tolerant of changeable weather and reliably produce large fruits.
• Early radishes – Early-maturing varieties with a short growing period provide crisp roots after only a few weeks. They are ideal for quick results and for encouraging children to take an interest in gardening.

Soil temperature is the deciding factor. If the soil feels cool and sticky when handled, it is worth waiting a little longer. Once it is crumbly and pleasant to touch, most seeds can be sown directly into the bed.

Rule of thumb: As soon as soil no longer sticks to your shoes, it is ready for sowing these old treasures.

Many people start more sensitive crops, such as tomatoes or squash, under protection first – indoors, in a greenhouse or beneath a simple polytunnel – before planting them outside later.

Preparing soil so grandfather’s varieties can get off to a strong start

Even the hardiest variety needs a good start. The key is to bring the soil to life rather than “overwork it”.

Gentle cultivation instead of old-fashioned digging

Rather than pushing a spade deep into the ground and turning the soil over, many experienced gardeners now loosen only the top few centimetres with a garden fork or broadfork. This largely allows soil life to remain in its own layer.

Next, spread a thin layer of mature compost over the bed. It works as a slow-release fertiliser and feeds earthworms and micro-organisms. The soil should crumble rather than smear.

Step	What to do?
1. Check the soil	Take a handful of soil, squeeze it and assess it: sticky or crumbly?
2. Loosen it	Carefully loosen the surface and break up large clumps
3. Add compost	Work in a thin layer of well-rotted compost
4. Level the bed	Use a rake to create a smooth, fine and crumbly surface

Getting sowing depth right is crucial

Many unsuccessful attempts have one simple cause: seeds are planted either too deeply or too close to the surface.

Remember: sowing depth = roughly two to three times the thickness of the seed.

Simply lay tiny seeds, including many herb seeds, on the surface and press them in lightly. Larger seeds, such as beans or squash, can be placed a few centimetres below the soil. Water gently afterwards – ideally with a fine rose, so the seeds are not washed back to the surface.

Care, protection and harvest: bringing back the flavour of the past

The first few weeks after sowing are the most delicate stage. Cold nights, hungry slugs and drying beds can seriously disrupt early growth.

Protect young plants from cold and stress

Spring often still brings cold nights in many areas. Those wanting to protect their old varieties can use simple measures:

• clear plastic cloches or cut-off bottles over individual plants
• horticultural fleece over full rows, placed on at night and aired during the day
• grass or leaf mulch once the plants have grown a little larger

Old varieties often develop deep-reaching roots. They cope with small variations in watering better than modern high-yield varieties bred for continual irrigation. The soil should not be allowed to dry out completely, however.

Harvest when ripe – do not pick too early

Patience is required to bring the intense flavours of the past to the plate. Many old varieties only develop their full flavour profile once their fruits are genuinely ripe. This is especially true of tomatoes, peppers and squashes.

The longer a fruit is allowed to ripen on the plant, the more complex its sweetness, acidity and fragrance become.

Radishes and lettuces, on the other hand, should not be left too long, or they can become woody or hot.

Saving your own seed: turning the garden into a seed vault

One major attraction of old varieties is the ability to propagate them yourself again and again. Unlike many hybrid breeds, these plants produce seed that will give similar offspring the following year.

From harvest to seed packet in five steps

• Select only healthy, vigorous plants as “mother plants”.
• Allow fruits to ripen completely; for some species, this means waiting until they begin to shrivel slightly.
• Remove the seeds or pips and clean them roughly. With tomatoes, this often includes a short fermentation in water to remove the gel coating.
• Spread them out on paper or cloth and leave them to dry for several days in an airy, shaded place.
• Put them into paper packets, label them with the variety, year and location, then store them somewhere cool, dry and dark.

Working this way gradually builds a personal collection of historical treasures – independent of supermarket shelves and seed companies.

More than nostalgia: ecological and practical benefits

The renewed interest in old varieties has a clear ecological dimension. The more different lines that grow in gardens, the broader the genetic base of our vegetables becomes. This helps with responding to new diseases, pests and climatic changes.

In addition, many old varieties attract insects with their flowers: bees, bumblebees and hoverflies find nectar and pollen, while hedgehogs and birds benefit in turn from the increased number of insects. Even a modestly planted balcony can become a mini-biotope.

Practical tips for beginners

• Begin with only a few crops, such as tomatoes and beans – it is better to keep things small and manageable.
• Use regional seed initiatives or seed swaps to find proven lines from your own climate zone.
• Keep notes: which variety grew where, what was the yield and how was the flavour?
• Choose varieties that you genuinely enjoy eating – that is more motivating than exotic experiments.

Anyone taking this approach soon notices that old varieties bring more than colour to a vegetable bed: they also brighten everyday life. They provide stories, memories and a sense of self-determination – and they usually taste simply better than produce from a standardised vegetable aisle.
