Sowing & growing

Mar-May, sow in-situ outdoors in shallow drills just 3-4mm deep. Alternatively, sow in pots or seed trays in moist seed compost and cover very finely with compost or vermiculite. Propagate at 20°C Transplant or thin out to 20cm between plants. Can be sown under cover Feb-Apr or even in Aug-Oct and overwintered for stronger plants the following spring.

Aftercare

Avoid feeding as this will increase foliage and reduce flowers. Deadhead regularly to prolong flowering.
