Silverbeet, a leaf & stem vegetable

Planting silverbeet
0

Both the leaves and the thick stalks go to the kitchen: silverbeet, or chard (Beta vulgaris), is eaten cooked or raw much like spinach, but is generally found to be sweeter. Around Nice it turns up in omelettes, pies and even desserts, and where the soil is kept moist, stalks can be cut from midsummer until the first frosts.

Sowing and planting silverbeet

Silverbeet is a vegetable that can be sown in spring or planted to the ground a bit later if you’ve purchased it in nursery pots.

Sowing silverbeet

If you would rather try to sow, either sow in Mid-spring or late spring in a nursery for cold-weathered climates or direct sowing for warmer regions.

Sowing silverbeet
Sow only once frost is no longer a risk
  • Take care that it doesn’t freeze anymore, or protect them with a plastic tunnel greenhouse if there is any risk.
  • Broadcast seeds and rake to bury them more or less 1 inch (2 cm) deep.
  • For nursery-sown seedlings, transplant to their growing bed as soon as 4 or 5 leaves have formed, spacing plants 12 to 16 inches (30 to 40 cm) apart on all sides.
  • For seedlings sown directly in the plot, thin to 12 to 16 inches (30 to 40 cm) as soon as the first leaves appear.

Planting silverbeet

Space plants 12 inches apart, rows 16 inches apart

If purchased in nursery pots, silverbeet can be planted all spring long, spacing them 12 to 16 inches (30 to 40 cm) apart on all sides.

  • For instance, you can plant each plant every 12 inches (30 cm) along a row, and plant the rows 16 inches (40 cm) apart.
  • Water regularly after planting to ensure that the substrate remains constantly slightly moist.

Silverbeet in a pot

Silverbeet in pot
Potted soil dries fast: water morning and evening

Growing silverbeet is possible in pots. It helps to have rich soil and excellent drainage.

It’s very important to water regularly, even more so than in the ground. Indeed, potted soil tends to dry out much faster.

Water morning and evening, without wetting leaves.

Four ways to start silverbeet, compared

Silverbeet can be sown under cover, sown straight into the plot, planted out from nursery pots or grown in a container. The spacing barely changes; what changes is the timing and the watering.

Four ways to start silverbeet, compared
Method When Spacing or depth Best suited to
Sowing in a nursery Mid-spring or late spring Transplant at 4 or 5 leaves, 12 to 16 in (30–40 cm) apart Cold-weathered climates
Direct sowing Mid-spring or late spring Seeds buried about 1 in (2 cm), thinned to 12 to 16 in (30–40 cm) Warmer regions
Planting nursery pots All spring long 12 to 16 in (30–40 cm) apart on all sides A quick start without sowing
Growing in a pot Spring One plant per pot, rich soil and excellent drainage Terraces and small spaces

Whichever route you take, the soil must stay slightly moist for the stalks to swell.

Harvesting silverbeet

Harvest of silverbeet
Take the larger stalks off at ground level

Usually the harvest season for silverbeet extends from Midsummer up to the first frost spells, depending on the time of sowing, planting, and on your needs.

  • Cut or break off the stalks at ground level.
  • Select the larger stalks first.
  • Harvest according to your needs.

Always leave the small central leaves in place: the growing point sits at the heart of the bunch and this is what pushes out the next flush of stalks.

Take only a few outer stalks per plant at each picking.

Go over the plants regularly even when you do not need much, because stalks left too long turn stringy and the leaves toughen.

Silverbeet in winter

There are 2 main phases regarding winter care for silverbeet, one phase is before it freezes and the other once the freezing season is over and the plants enter their vegetation phase.

Before the first frost spells

Silverbeet winter
Mound soil around the bunch before the frosts
  • Best is to protect your silverbeet from the cold.
  • Ridge up a small mound of soil around the bunch, up to where the leaves are.
  • Cover everything with a thick layer of dead leaves.
  • Straw and dried fern fronds also insulate well.
  • On warmer days, uncover the mulch to aerate a short while, then cover again.

Silverbeet after winter

  • Remove the dried leaf cover at the end of winter to reveal the leaves.
  • You can start harvesting your silverbeet stalks again.
