Astilbe 'Radius'

Try to plant in a location that enjoys dappled sun and remember to water often. Keep in mind when planting that Radius is thought of as hardy, so this plant will survive close to or on freezing temperatures. A soil ph of between 5.6 and 7.5 is ideal for Radius as it does best in weakly acidic soil - weakly alkaline soil.

Ensure a seed sowing distance of 1.46 feet (45.0 cm).

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