There is a perfect spot in every yard and garden for Louisiana irises. You are rewarded year after year with spectacular color blooms that brighten your home and garden.

AFTER PURCHASE CARE

Place rhizomes in water until ready to plant. The foliage should be out of the water. The irises can remain in this condition for about one month.

PLANTING

The ideal location for planting is full sun with afternoon shade. At least one-half day of sunlight is necessary for bloom to occur. Once location is determined, the elevation of the bed may vary. Louisiana irises do not have to be grown in a boggy condition. The beds may be ground level or above, or they may be planted in low areas that contain up to six inches of water.

WATERING

During growing season, between September through April, the iris should be watered and soaked about once a week. Hopefully normal rainfall will interrupt this necessity, but the area should remain damp for best results.

WATER CULTURE

Louisiana irises are born to be grown in water. If water culture is your intended purpose, place rhizome in an 18" diameter pot. The depth of the pot should be at least 8" inches. Plant rhizome about 2" from the surface of the soil.

MULCHING AND FERTILIZING

Louisiana irises are heavy feeders. What is lacking in the soil may be supplemented with 8-8-8 fertilizer in September/October and another dosage of 8-8-8 in late February to enhance growth and bloom. Do not fertilize in winter months with nitrogen. Do not place fertilizer directly on top of rhizome. Cover irises with mulch to keep moisture in ground and in summer months for sun protection. Recommend 2 to 4 inches of pine needles, semi-rotten leaves, bagasse or cypress shavings.

BEST PLANTING LOCATION:

A place with at least ½ day of sun.

DEPTH:

1-2 inches below surface, and approximately 12-18 inches apart.

BEST SOIL TYPE:

Louisiana irises like an acid soil, similar to azaleas.

CARE AFTER BLOOM

After bloom the plant begins its dormant stage. In late May or June, you may wish to cut the dying foliage back to about 2-3 inches above ground level. Mulch and keep as damp as possible.
