Phormium prefers a rich, moist soil and a location sheltered from harsh winds, but once established, the plants really aren’t fussy about conditions. Phormium can easily be grown in containers. Choose a rich, organic mix over traditional potting soil and keep the plants well watered in summer’s heat.
How do you grow Phormium plants?
- Collect ripe seed and sow in spring. Just lightly cover the seed with compost/vermiculite and keep at 18°C (64°F) in a propagator or airing cupboard.
- Germination can take up to a year.
How do you look after a Phormium plant?
Water pot-grown phormiums regularly to keep the soil evenly moist but take care not to over-water. Feed each spring with a controlled release fertilizer, and pot on into a larger container if the roots are congested. Keep phormiums looking smart by removing dead leaves and flower stems two or three times a year.
