Potato 'Royal Blue'

Try to plant in a location that enjoys partial sun and remember to water moderately. Keep in mind when planting that Royal Blue 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. Planting Royal Blue in loamy and clay soil with a ph of between 5.0 and 6.0 is ideal for as it does best in moderately acidic soil to weakly acidic soil.

Try to aim for a seed spacing of at least 11.7 inches (30.0 cm) and sow at a depth of around 5.85 inches (15.0 cm).

By our calculations, you should look at sowing Royal Blue about 14 days before your last frost date.

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