Growing Instructions
- To maximise germination seeds should cold-treated (stratified) first. Place the still-sealed packet in the salad drawer of the fridge for a week or two.
- For most sowings the plants will flower in the second season although a limited display may be obtained from a very early spring sowing under cover with warmth.
- Best sown thinly from May to August in trays with fine seed compost outside or under unheated glass. Cover seeds lightly with 1/8 inch of fine compost or vermiculite and keep moist.
- Germination can be up to 3 weeks depending on soil temperature.
- When 2 in high thin and transplant to large plugs or separate pots and grow on. Beware young plants left outside are attractive to slugs and snails and will need protection.
- Plant out to their growing positions in Sep / Oct and provide support as soon as stems start to form in early spring.
