Harvest Type

Brussels' Sprouts are a continuous harvest crop. You pick only the ripe fruit and allow the smaller fruit to mature.

TIP: Check Brussels sprouts often for aphids.

Transplant / Direct Sow

You can transplant or direct sow Brussels sprout seeds.

When to Plant:

For fall gardening in warmer climates, start seeds indoors six or so weeks before the first frost date. For spring gardening, transplant outdoors when the ground is workable.

Days to germinate

7-12 days

Days to maturity

It takes about 80-90 days for Brussels sprouts to mature.

Planting Depth

Plant seeds 1/2" deep.

Germination Temperature Range

Brussels' Sprouts are cool weather loving plants. They will germinate when the outside temperature is between 45-80°F.

Spacing Between Plants

Brussels sprouts are big plants, so space the seedlings 18" apart.

Growing conditions

Brussels sprouts do well in slightly acid soil that has a 6.0-7.0 pH range. They like nitrogen but not too much. Aim for a balance that keeps the plant producing fruit rather than leaves. A 10-10-10 N-P-K ratio fertilizer is optimal.

Companion Plants

Other brassica plants grow well with Brussels sprouts such as broccoli or cauliflower.

Rotation

Rotate Brussels sprouts each year or amend the soil with nitrogen-rich compost.

Anticipated yields

Plan your garden yield at 1/2 pound of Brussels sprouts per plant and about eight plants per person.
