Dinner Plate Dahlia 'Cornish Ruby'

Try to plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Cornish Ruby 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.

Try to aim for a seed spacing of at least 11.7 inches (30.0 cm) and sow at a depth of around 0.39 inches (1.0 cm). Soil temperature should be kept higher than 20°C / 68°F to ensure good germination.

By our calculations, you should look at sowing Cornish Ruby about 60 days before your last frost date.

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