About Iris Flower Bulbs

Iris Flower Bulbs grow in full sun positions. The figures below are the ones on the packets in this group; each product page carries the exact numbers for that variety.

When to plant

Plant in fall. Bulbs go in while the soil is still workable, and want to be in the ground long enough to settle before it freezes. Hardy in zones 3 to 10 — your local frost dates decide the exact week.

Where to plant

Choose a site in full sun. Water needs are average, low once the plants are established. Drainage matters more than anything else: bulbs sitting in wet winter soil rot.

How to plant

Follow the depth given on the product page; it differs between the varieties in this group. Water gently to settle the soil, then keep the surface evenly moist until seedlings or shoots appear.

How to care

Keep watering average, low, at the base of the plant rather than over the leaves. In zones 3 to 10 these come back each year: let the foliage die down naturally after flowering, since that is what feeds next season's growth.
