Rosemary (Salvia rosmarinus 'Renzels' IRENE) should be watered thoroughly and evenly. Allow the soil to dry out between waterings; then water deeply but not so much that the soil is soggy. For plants in containers, water when the top 2-3 inches of soil is dry. Plants in the ground should only be watered when the soil is dry down several inches. Watering should be done in the morning so that the leaves can dry during the day and not be left wet overnight, which can encourage fungal disease.

Rosemary (Salvia rosmarinus 'Renzelse IRENE') requires around 6 to 8 hours of full sun each day for optimal growth. It is best to provide this sunlight in the morning, when temperatures are cooler and the sun is not as intense. If planted in an area with afternoon sun, the plant should be shaded or provided with extra watering. In areas that receive intense extreme heat, the plant should be shaded as well.

Rosemary (Salvia rosmarinus 'Renzels' IRENE) should be pruned regularly to keep its shape. It is best to prune it after the spring flowering or in mid-summer. When pruning rosemary, remove no more than a third of the branches each time, making sure to stay at least 1-quarter inch away from the main stem. Shorten the current season's branches and remove any weak, diseased or dead branches. Additionally, keep an eye out for any branches that are too close to the center of the plant as these can block the light and prevent airflow. Finally, it is important to shape the rosemary plant to a natural form that is pleasing to the eye.
