Siberian iris

Water your Siberian iris (Iris 'Dewful') plants weekly, soaking the soil well. Water in the morning so the foliage has time to dry out, and avoid splashing the foliage as this can lead to an increase in fungal disease. Allow the soil to become somewhat dry between waterings, as Siberian iris will tolerate some drought. This is particularly important during periods of too-hot and dry weather, as too much water can stress the plants.

Siberian iris (Iris 'Dewful') likes plenty of direct sunlight throughout the day when possible. This particular species of iris will benefit from about 6 to 8 hours of full sunshine a day, with some morning and some late afternoon sun. Partial shade is okay too, but the full sunshine helps the plants to develop more robust, fuller blooms. During the hottest summer months it may be beneficial to give them some respite from the hottest hours of the day by providing afternoon shade.

For optimal growth and flowering, Siberian Iris (Iris 'Dewful') is best pruned in early spring, just as new growth begins. Using sharp, clean shears, prune off any dead, diseased and damaged branches, and then prune back any overly long growth by up to 1-third of its length. This will help ensure that your Iris 'Dewful' stays strong and healthy throughout the growing season.
