Irises need to be watered weekly if sufficient rainfall is not received .They can be grown in full sun or in half shade. They like an acid soil, with a ph of 6.5 or less. Be sure to amend your soil if it is sandy, with organic matter, and mulch on top with leaves, pine straw or bark. Make sure the rhizome is about 1" below soil surface.
You'll need to fertilize three times a year, around October and again in early spring about February and again in June. You can use a organic or a slow release fertilizer. The irises will multiply over summer into fall when they can be divided. Louisiana Iris are highly disease resistant and few, if any, insects bother them. They are evergreen here.

The Louisiana Irises will begin blooming in late February here, with peak season being April. Each stalk will have 5-8 buds and its own bloom time table so a garden collection of irises will be in bloom for up to 2-3 months. They also make an excellent cut flower. After they finish blooming remember to cut the flower stalk off just above ground level.
