Frequently Asked Questions (FAQs)

1. What is the best time to plant iris bulbs?

Hot and humid conditions do not sound like a good time to garden. If you are a lover of iris, forget about the weather as there is work to be done. Late July through mid August is the best time to plant, move or divide iris. Iris is one of the most popular perennials in the garden and easy to grow.

2. Can I leave iris bulbs in the ground?

The best time to dig up iris bulbs or rhizomes in the garden is between the last days of summer and early fall. Lift the clump of iris plants from the ground with a spade or fork. Try to lift the entire bulb to ensure the plant survives the move.

3. What do you do with iris bulbs after they bloom?

Split the irises every year, after flowering has ended during June. At this point the early summer leaves and flower stems have started to die back, and the late summer leaves have started to grow. 2. Split individual plants by cleaving the rhizomes with a spade, leaving the part to be retained undisturbed in the soil.

4. Where is the best place to plant iris bulbs?

Where to Plant. Iris need at least a half day of sun. In extremely hot climates some shade is beneficial, but in most climates Iris do best in full sun. Be sure to provide your Iris with good drainage, planting either on a slope or in raised beds.
