Irises are wide-ranging and varied, with the genus containing around 250 different species to pick from to provide bursts of glorious color in your garden. They come in bulb forms and rhizome types, and all types will benefit from an annual fertilizing plan.
If you are growing irises, feeding them at the correct time, and with the right fertilizers, will promote strong blooming and keep the plants healthy. Irises have specific nutrient requirements and plants may not flower and be at risk of disease if you fail to get the nutrient balance right.
