Calendula 'Flashback mix'

Try to plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Flashback mix is thought of as half hardy, so remember to protect this plant from frosts and low temperatures. Ensure your soil is loamy and has a ph of between 6.1 and 7.8 as Calendula is a weakly acidic soil to weakly alkaline soil loving plant.

Direct seed when danger of frost has passed, or start indoors 4-6 weeks before last frost date.¹

Try to aim for a seed spacing of at least 7.8 inches (20.0 cm) and sow at a depth of around 0.39 inches (1.0 cm). Soil temperature should be kept higher than 60°C / 140°F to ensure good germination.

By our calculations, you should look at sowing Flashback mix about 35 days before your last frost date.

If starting indoors, transplant after danger of frost has passed.¹

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Flashback mix is a half hardy plant.
