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.
