    15 Jun to 10 Sept Dates as each sowing reaches this stage

    When seedlings are large enough to handle, from 15th June, prick them into individual pots. Pot them on before they get rootbound so they make sturdy plants.

    From 25th August to 12th June 2027, pick off fading blooms. Snip back to a leaf and take off any yellowing foliage as you go.

  6. 06
