Pests and Diseases
Louisiana irises are not subject to many disease problems, although those
two common problems, rust and leaf spot can devastate them. Treatment is with any suitable fungicide- Mancozeb
seems to be the most effective—and it should be applied quickly and at weekly intervals if / either of the problems
arise. Prevention would be regarded as far more acceptable than cure.
If leaf spot does occur, and it will on certain cultivars in humid weather or when cool nights are followed by
warm days, then removal of the infected leaves and treatment of the others is advisable.
The Louisiana iris is an ideal garden plant for a bog situation or for growing in standing water. For this reason
many gardeners like to grow them in pots. Potted plants are beautiful in flower and give accent to a pool at any
time of the year but care must be taken with the mixture used. Pots should be as large as possible to cope with
the vigorous growth and the mixture should be of garden soil, peat moss, compost and well-rotted manure in about
equal proportions. It should be fertile and an 8—9 month slow release fertiliser should be incorporated in the
soil at planting time.
