Saxifraga 'Brno'

Keep in mind when planting that Brno is thought of as half hardy, so although it can survive a small mild cold snap, it is wise to ensure that this plant is protected from frost damage. A soil ph of between 5.6 and 7.5 is ideal for Brno as it does best in weakly acidic soil - weakly alkaline soil.

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