Scabiosa spp.
A reliable half-hardy cottage-garden flower for UK borders and cutting. Sow under cover in spring or plant out young plants after the risk of frost, then keep them deadheaded for a long flowering season.
Step-by-step instructions for growing Scabious
Sow seeds into modules from 27th February to 23rd March, covering them with a light seed sowing depth of . Keep the compost just moist and place the tray somewhere bright and cool for steady germination.
When seedlings are large enough to handle, move them on from 25th March to 8th April into small pots. Handle them by the leaves, not the stems, and keep them growing on in good light.
Acclimatise the young plants from 30th March to 13th April by putting them outside for longer each day. This stops check when they go into the border and prepares them for cooler UK nights.
Plant out from 27th April to 11th May once frosts have passed and the soil has warmed a little. Space plants apart, water them in thoroughly straight away, and protect them from slugs and strong winds while they settle.
Start deadheading from 3rd June and keep going until 21st October. Remove fading flowers regularly so the plant puts its energy into more blooms instead of setting seed, and keep the soil evenly moist in dry spells.
