Iris 'Concertina'

Try to plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Concertina is thought of as very hardy, so this plant will tend to go dormant over the long winter months. Try to keep the ph of your soil between the range of 6.1 and 7.8 as Concertina likes to be in weakly acidic soil - weakly alkaline soil.

Aim to sow 0.99 inches (2.55 cm) deep and try to ensure a gap of at least 1.19 inches (3.05 cm).

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Concertina is a very hardy plant.
