Irises

You can plant these as early as late summer, but fall is the best time as the cool weather and occasional rains help the plants establish themselves better. This is then followed by a long winter rest so that they can come out in spring with vigor and vitality.

Irises need fertile soil that is tilled one-foot deep, but their rhizomes should not be planted too deep in the soil. They should be partially exposed while the roots should be covered by a few inches of soil. Water the plant regularly to help it get established and add as much mulch as possible for protection from the winter.
