Dinner Plate Dahlia 'Classic Rosamunde'

Try to plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Classic Rosamunde 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 Classic Rosamunde about 60 days before your last frost date.

As Classic Rosamunde is tender, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.
