Growing guide

Step-by-step instructions for growing Mooli

  1. 01

    Prepare the bed

    31 May to 31 Aug

    Work the soil to a fine tilth and remove stones, lumps, and old roots so the roots can grow straight. Do not add fresh manure, because it encourages forking and split roots. Aim to finish this work around 31st May - 31st August.

  2. 02

    Sow seeds

    31 May to 31 Aug every 3 weeks

    Sow seeds directly where they are to grow, about deep. Space them lightly in rows and sow a fresh batch every 21 days for a steady run of roots through 31st May - 31st August.

  3. 03

    Protect from root fly

    31 May to 31 Aug

    Cover the row with fine insect mesh straight after sowing and keep it sealed at the edges. Leave the cover in place from 31st May so adult cabbage root fly cannot lay eggs near the seedlings.

  4. 04

    Thin seedlings

    6 Aug to 13 Aug

    Thin seedlings carefully once they are up, leaving the strongest plants to stand. Aim for apart, and do the thinning in stages if the row is crowded so you do not disturb nearby roots. This is usually done around 6th August - 13th August.

  5. 05

    Keep growing

    30 Jul to 24 Sept

    Water evenly from 30th July so the roots swell steadily and do not become pithy or split. Keep the bed weed-free and use fleece or mesh if flea beetle or root fly is active.

  6. 06

    Harvest roots

    24 Sept to 20 Nov

    Lift roots as soon as they are large enough to use, usually from 24th September through 20th November. Pull them before they become tough, and leave later sowings in the ground only while the soil stays workable.

Plants to avoid

Why companion planting matters

Companion planting can deter pests, improve pollination, and make better use of space. Some plants confuse pests or attract beneficial insects; others improve soil or offer shade to neighbours that need it.
