Those who enjoy plants and gardening know that the iris is one of the most hardy and attractive perennials one can grow. Available in many different varieties, the iris plant is perfect for both beginning and experienced gardeners, as it is relatively easy to care for and is impressive when in full bloom. By learning the many nuances of growing irises, you can increase your chances of success with the plant.
Planting Date
Many people don’t realize that irises need to be planted at a certain time of the year in order to thrive, as when planted either too early or too late, irises will have difficulty growing correctly. Irises should ideally be planted in late summer months (July, August or September). In hot climates, however, irises may do best when planted in October.
Sunlight Needs
Like all plants, irises require sunlight in order to grow correctly. The iris needs at least 12 hours of sun each day to grow uninhibited, especially in cooler climates. While shade is usually not recommended, partial shade may be useful in overly hot climates. Irises should also be planted on slopes or hills that face the sun, which will facilitate drainage.
Water Needs
Irises need a fair amount of water to grow. Unfortunately, it is rather difficult to say exactly how much water a particular iris plant will need, as this can differ significantly depending upon soil preparation, climate and other factors. Generally, it is better to water thoroughly (at long intervals) than it is to water frequently and in small amounts. Be careful not to over-water your iris, however, as this is one of the most common reasons for growing failures. For beginners, it is best to go by the rule of not watering any plants if the soil is even slightly moist.
