blackberry lily

Blackberry lily (Iris domestica) should be watered frequently but lightly to maintain moderately damp soil. Watering should be done every 3-4 days, using a gentle stream from a watering can or hose, aiming not to wet the leaves too much. The lilies may even benefit from a light misting with water. During very hot and dry weather, increase water frequency to about every 2 days. Make sure to never allow the soil to completely dry out. When temperatures become cooler, reduce the amount of water, but continue to keep the soil moist.

Blackberry lilies should receive at least 6 hours of direct, unfiltered sunlight each day for optimal growth and flowering. The sun should be on the plant for the majority of the day, with the exception of during the hottest part of the day when the sun can be too strong. Watering should also be monitored during the hot periods of the day; if it is too hot, the plants need less water. During the cooler months, water and sunlight levels can both be increased but not to the same extent as during the growing season.

For Blackberry lily, prune the clumps in the spring after the foliage has died down, but before the new growth appears. Cut out any dead or damaged leaves and stems at the base of the plant. Do not remove more than 1 third of the foliage in any 1 season. Regular pruning will help promote healthy and vigorous growth every season.
