|We are in zone 8. Each year, our winter temperaturs will get down low enough where our African Iris leaves will become frostbit. In the spring, these leaves are dead but new growth comes from the rhizomes. Should we prune off the dead leaves before the new growth comes out? Thanks for your advice.
|Dietes, also called Fortnight Lily or African Iris, are hardy enough to leave in the ground all year around in your California garden. Wait until new growth appears in the spring and cut away the dead foliage. Leaving it until early spring will provide the rhizomes with a tiny bit of protection from frost. Enjoy your plants!|
