One of the easiest ways to extend your iris season is to plant a few Louisiana irises in your beds. If you are gardener who raises irises, as well as, daylilies, Louisiana irises will fill in the bloom between the two bloom seasons.

Louisiana irises can be grown in any type of fertile soil, though they prefer somewhat acidic soil. The best time to transplant them is in early autumn when the summer heat has passed. I use any type of low nitrogen fertilizer. 8-8-8, 10-20-0 works well or use granulated geranium or azalea fertilizer. A little each month does wonder for their growth. Autumn application is around Halloween and Spring when the crocus bloom.

Plant the rhizomes 3” deep and keep watered until new growth begins. Mulch them the year round and one good watering each week during the hot summer months is a must. Do not allow them to go dormant during the summer.

The bloom stalks range from 10 to over 50 inches in height. Cut all bloom stalks after the last flowers fade. Remember that allowing seed pods to form and mature will result on a reduction of buds the following year.

Here are some older varieties I would highly recommend to the beginner if they want to grow a few Louisiana irises. Just remember, most are rapid increasers and must be transplanted every two years. Three year clumps can yield lots of increase and huge clumps. One half to full sun is recommended.
