Iris should be planted in July, August or September, so that the roots of newly planted Iris are well established before the growing season ends. Iris are also available as potted plants in the perennial lot, and these can be planted in spring, summer or fall.

 

soil preparation

Iris will thrive in well-drained garden soil. Planting on a slope or in raised beds helps ensure good drainage. If your soil is heavy, coarse sand may be added to improve drainage. Gypsum is an excellent soil conditioner that can improve most clay soils. The ideal pH is 6.8 (slightly acidic), but Iris are tolerant in this regard. To lower the pH of your soil, sulphur may be added to alkaline soils.

 

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.

 

depth to plant

Iris should be planted so the tops of the rhizomes are exposed and the roots are spread out facing downward in the soil. In very light soils or in extremely hot climates, covering the rhizome with 1 inch of soil may be desirable. Firm the soil around each rhizome and then water to help settle the soil. A common mistake is to plant Iris too deeply.

 

distance apart

Iris are generally planted 12 to 24 inches apart. Close planting gives an immediate effect, but closely planted Iris will need to be thinned often. Plants spaced further apart will need less frequent thinning.
