Beetroot (beet) microgreens: everything you need to know to grow them

Beetroot (beet) microgreens are young beet seedlings (Beta vulgaris) cut at the first-leaf stage, when they carry vivid magenta-red stems beneath a pair of soft green leaves. They are among the most decorative greens you can grow at home, and they taste like a gentler, sweeter version of mature beetroot leaves rather than of the root itself. Beetroot is a slower, steadier crop than most, but it is forgiving enough for a first attempt and, once you have seen the colour, hard to give up. If the whole process is new to you, start with our Grow at Home hub and come back here for the beet-specific detail.

Why grow beetroot (beet) microgreens

Beetroot earns its place mainly on looks. The stems are a saturated red that almost nothing else in the microgreen world can match, so a small pinch lifts a plate far more than the effort suggests. The flavour is mild and earthy with a faint sweetness, far less pungent than a peppery brassica such as radish or broccoli, which makes beetroot easy to use generously.

• Some of the most intense colour available, close to red amaranth but with larger, easier seed.
• A mild, sweet-earthy flavour that suits anyone who finds hot, peppery microgreens too strong.
• Large seed and a wide harvest window, so exact timing is not critical.
• Honest caveat: it is slow, and the papery seed husks cling to the leaves, so expect a little tidying at harvest.

How to grow beetroot (beet) microgreens step by step

1. Start with untreated, food-grade beet seed. Beet sold for field planting is often dyed and coated with fungicide, which must never go anywhere near food — if you are unsure what you have, read our guide to choosing microgreens seeds.
2. Decide whether to soak. Each beet “seed” is really a dried seedball that can hold more than one seed, so a single ball may send up two or three seedlings. Soaking for four to eight hours can nudge germination along, but side-by-side tests show little real difference, so sowing dry is perfectly fine.
3. Sow fairly densely and evenly over about 2 cm of pre-moistened soil or coir — roughly 20 to 30 g of seed for a standard 1020 tray. Press the seed gently so it makes firm contact with the surface.
4. Cover the tray to create a blackout and set a light weight on top. The weight keeps the seed pressed into the medium and encourages strong rooting. Mist lightly once or twice a day so the surface stays just damp, never soaking.
5. Uncover on about day five or six, once most seedlings are up and the stems are stretching. Move the tray into bright, indirect light for at least twelve hours a day and let the stems colour up.
6. Switch to watering from below, letting the tray drink from a shallow reservoir rather than misting the tops. Dry leaves are your best defence against damping-off. Grow on until the greens stand a few centimetres tall, usually between ten and sixteen days.

Harvesting and storing

Beetroot has a generous window, but it is at its best a little earlier than you might expect — around day ten to twelve, while the stems are deep red and the leaves still tender. Left too long, the stems begin to toughen, the leaves yellow and the flavour turns sharply earthy. Harvest by gathering a handful and cutting cleanly just above the soil with sharp scissors, keeping as much of the coloured stem as you can.

Because the tops are cut dry — one more reason to water from below — they keep well. Blot off any surface moisture, then store them in a lidded container or bag in the fridge, where they hold for around five to seven days. Rinse them only just before you use them.

How to use them in the kitchen

The whole point of beetroot microgreens is colour, so use them where they will be seen. They are mild enough to scatter over almost anything: feta or goat’s cheese salads, hummus, avocado toast, soups, risotto or a plate of smoked fish. The red stems bleed a little once dressed and can tint a pale dish pink, which is usually a feature rather than a fault. Pair them with citrus, walnuts or a sharp vinaigrette to bring out the sweetness, and treat them much as you would any delicate raw garnish.

Common problems

• Clinging seed husks. Papery husks stick to the cotyledons and there is no magic fix — most growers simply pick off the worst by hand at harvest. Sowing evenly and not too thickly helps.
• Slow or patchy germination. Because beet seed is a multigerm ball, emergence often looks uneven. Give it time — the blackout can run to a full six days — and keep the medium evenly damp throughout.
• Overwatering and mould. A soggy surface is the leading cause of failed beet trays. Water from below, keep the air moving, and see our notes on preventing mould if fuzz appears. Do not confuse a fine, even halo of white root hairs near the base with mould — root hairs vanish when lightly misted.
• Leggy, pale stems. Stretched, washed-out greens want more light once uncovered — aim for twelve hours or more a day.
• A note on oxalates. Beetroot is related to spinach and chard and, like them, contains oxalates. The small amount in a garnish is not a concern for most people, but anyone advised to limit oxalate — some people prone to kidney stones, for instance — may prefer to go easy. Our guide to which microgreens need care puts this in context.

Beetroot rewards a little patience with a colour few other crops can offer, and once you have grown a single tray you will want it on hand for every plate that needs lifting.
