Growing guide
What to do through the growing season
01
Prepare the Bed
2 Apr to 23 AprWork the soil deeply and break it down to a fine tilth around 2nd April - 23rd April. Remove stones and any hard lumps, then mix in well-rotted compost. Avoid fresh manure, because it makes the roots fork.
02
Sow Seeds Indoors
14 Feb to 5 MarSow seeds thinly on the surface of moist seed compost around 14th February - 5th March and cover with a light dusting of vermiculite. Keep them at in bright light and keep the compost evenly moist.
03
Prick Out Seedlings
7 Mar to 9 Apr Dates as each sowing reaches this stageWhen seedlings are large enough to handle, prick them out from 7th March - 9th April into individual small pots or modules. Handle them by the leaves and keep the young plants in bright light with evenly moist compost.
04
Harden Off and Plant Out
30 Apr to 14 MayHarden plants off for 7 to 10 days, then plant out around 30th April - 14th May after frost risk has passed. Space plants apart with the crown at soil level. Water in thoroughly and keep the soil evenly moist.
05
Harvest Roots
5 Sept to 26 Nov Dates as each sowing reaches this stageLift roots from 5th September and keep harvesting through 26th November. Leave sound roots in the ground over winter if the soil drains well, then lift them as needed before they start to run down.
