The single most influential factor in your Japanese Iris' health and growth is WATER. Plants with insufficient moisture will be stunted and have smaller flowers, but with plenty of consistent water, they will grow big and beautiful. They are well suited to areas beside ponds or near streams where the water table is high, but not covering the roots. Mulching them heavily will ensure that the soil never dries out. Plant in heavy, acidic, rich soil amended with compost or manure. Don't add granular fertilizer around new plantings. Instead, add the fertilizer a month or two prior to planting Japanese Irises. When they are more established you can fertilize them in early spring and then right after they finish blooming.
