Plant iris bulbs by choosing the right time, planting them in a good location, digging shallow holes, planting the bulbs, and watering and mulching them. You need a garden trowel, iris bulbs, organic mulch and water.
- Plant bulbs at the right time
Plant iris bulbs either in the fall or winter depending on the USDA zone in which you live. Bulbs in a zone 8 should be planted in the fall while bulbs in zones 9 and 10 can be planted any time from August to January. Planting time also depends on the type of iris bulbs. Some types, such as Dutch iris bulbs, are more hardy than others and can withstand harsher temperatures.
- Choose a good location
Choose a location that gives the flowers plenty of room to spread. The soil needs to be well-drained with a pH between 6.8 and 7.0. The bulbs need access to direct sunlight.
- Dig shallow holes
Dig shallow holes for the bulbs that are between 1 and 2 feet apart.
- Plant the bulbs
Place the bulbs in the holes so that the rhizomes are above the soil line. Cover the bulbs with soil.
- Water the bulbs
Water the newly planted bulbs well and regularly.
- Mulch the bulbs
Add a layer of mulch on the soil over the bulbs to protect them from the cold.
