Mulching around the plants can help retain soil moisture.

Soil: Louisiana Iris prefers rich, slightly acidic soil that is moist and well-draining. They can tolerate a range of soil types, including clay, loam, or sandy soil.

Follow the package instructions for application rates. In subsequent years, you can apply a balanced liquid fertilizer during the growing season to promote healthy growth and abundant flowering.
