<human>:  How do I plant iris bulbs?
<bot>: To plant iris bulbs, start by finding a location in your garden that has good soil drainage and gets full sun. Then dig a hole about 3-4 inches deep for each bulb. Place the bulbs in the hole pointy end up, and firm the soil around the bulbs. Cover the bulbs with soil, water them well, and keep them well-watered throughout the growing season.
