Why heritage vegetables deserve a place in your plot

Heritage, or heirloom, vegetables are simply older, open-pollinated varieties that have been passed down through generations of gardeners, often by saving seed year after year. That history matters. Because they were selected in real gardens and allotments rather than for the supermarket shelf, they tend to be sturdier, more forgiving of British weather and far more interesting on the plate. You will find purple-podded peas, stripy beetroot, knobbly squash and tomatoes in shades you never see in a shop.

They also taste better. A 'Pink Fir Apple' potato boiled and buttered, or a 'Crimson Flowered' broad bean picked young, bears little resemblance to the bland versions we have grown used to. Best of all, heritage varieties are usually cheap to grow because you can save your own seed and swap it with neighbours, which is how these plants survived in the first place.

Choosing sturdy varieties for a first season

Start with crops that virtually grow themselves. Climbing French beans such as 'Cherokee Trail of Tears' are dependable, prolific and look handsome clambering up a wigwam of hazel sticks. Beetroot 'Bull's Blood' gives you deep red leaves for salad as well as roots, while 'Burpee's Golden' adds a cheerful orange to the veg patch. Kale 'Nero di Toscana' and 'Red Russian' will crop right through the winter with very little fuss.

Match the variety to your soil. On heavy clay, short-rooted carrots such as 'Paris Market' succeed where long ones fork and sulk. On light, sandy ground, parsnips and long carrots revel. For a small plot, look for climbing rather than bush types, and choose cut-and-come-again salad leaves such as 'Salad Bowl' or 'Winter Density' lettuce to fill gaps between slower crops.

Leave cauliflower, celery, aubergines and melons until you have a season or two behind you. They are not difficult so much as unforgiving, and there is no need to make life hard for yourself.

Building soil with compost

Almost every problem in a vegetable patch comes back to the soil, and almost every solution does too. Heritage varieties were bred on ground that was fed generously with manure, leaf mould and kitchen waste, so give them something similar. Spread a layer of well-rotted compost or manure about five to eight centimetres deep over the beds in autumn or early spring and let the worms do the digging for you.

• For leafy crops such as kale, chard and cabbage, compost rich in kitchen waste and grass clippings supplies the nitrogen they crave.
• For roots such as carrots, beetroot and parsnips, use older, well-rotted leaf mould instead. Fresh manure makes roots fork and split.
• For peas and beans, add a little wood ash if you have it, and do not overfeed; they fix their own nitrogen and will simply grow leaf at the expense of pods.
• For brassicas, a sprinkling of lime in winter helps prevent clubroot on acid soils.

The no-dig approach suits heritage growing beautifully. By layering compost on top and never turning the soil, you protect the fungal networks and worm runs that keep plants healthy, and you disturb far fewer weed seeds.

Watering that keeps crops happy

Consistency matters more than quantity. A gentle soak twice a week, delivered to the base of the plant in the cool of the morning, beats a daily flick of the watering can every time. Shallow watering encourages shallow roots, which then wilt at the first dry spell.

Mulch generously with compost, straw or grass clippings to hold moisture in the ground and keep the soil temperature steady. Heritage tomatoes are especially sensitive to irregular watering: let them dry out and then flood them, and you invite blossom end rot and split skins. Aim for an even, steady supply, particularly once fruit has set. If you can, sink a plastic bottle with a few holes punched in it beside thirsty plants such as courgettes and fill it instead of the surface.

Rural traditions worth keeping

Growing heritage vegetables is as much about habit as horticulture, and some of the old ways are simply good practice. Saving seed from your best bean plants, the ones that cropped earliest and tasted finest, costs nothing and gradually tunes the variety to your own patch of ground. Let the pods dry on the plant, shell them on a wet afternoon, and store the seed in labelled paper envelopes somewhere cool and dark.

Companion planting is another tradition worth reviving. Scatter nasturtiums and marigolds among your brassicas to draw aphids away, and let a few flowers run to seed at the plot's edge to feed the pollinators that will pay you back in beans and courgettes. Keep a simple notebook of what you sowed, when it came up and how it cropped. Sharing gluts with neighbours and swapping spare seedlings over the fence is not sentimentality; it is how these varieties got here.

Common pitfalls in a first season

• Sowing too early. Wait until the soil has warmed properly in spring. Cold, wet seed simply rots.
• Sowing too thickly. Thin seedlings ruthlessly. Crowded plants are weak plants.
• Forgetting to net. Pigeons will strip brassicas in an afternoon, and cabbage white butterflies lay eggs on the underside of leaves.
• Neglecting slugs. A nightly torchlit patrol in damp weather saves more seedlings than any remedy.
• Losing the labels. Write the variety name on the label in pencil, not ink, so it survives the rain.

Be patient. A first season rarely looks like the pictures, but it will give you a handful of crops that taste of somewhere real, and a seed tin already worth passing on.
