How to grow Calendula 'Chrysantha'

  • Full Sun

  • Medium

Direct sow calendula seeds where they are to grow from April to May. The position should be in full sun on well drained soil. Sow seeds thinly at a depth of 1/2 inch. Germination should take from 5 to 10 days. Thin them, when large enough to handle, to 12 inches apart.1

Plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Chrysantha is thought of as tender, so remember to wait until your soil is warm and the night time temperature is well above freezing before moving outside. Chrysantha requires a loamy soil with a ph of 6.1 - 7.8 - it grows best in weakly acidic soil to weakly alkaline soil.

Growing Chrysantha from seed

Try to aim for a seed spacing of at least 7.8 inches (20.0 cm) and sow at a depth of around 0.2 inches (0.5 cm). Soil temperature should be kept higher than 10°C / 50°F to ensure good germination.

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

Transplanting Chrysantha

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Chrysantha is a tender plant.
