Cultivation and care of Philadelphus coronarius

Philadelphus coronarius, or mock orange, is relatively easy to grow and care for, making it an excellent choice for both experienced gardeners and beginners. Here are some essential tips for cultivating and maintaining this enchanting shrub/

Location and Soil

Mock orange thrives in full sun to partial shade, so choose a location that receives at least six hours of direct sunlight each day. The soil should be well-draining and moderately fertile. Mock orange can tolerate a wide range of soil types, including clay, loam, and sandy soils. However, it is crucial to avoid waterlogged or excessively dry soil, as this can hinder the plant’s growth and health.


The best time to plant mock orange is in the spring or fall, when the weather is mild. Before planting, prepare the soil by removing any weeds or grass. Dig a hole that is slightly larger than the root ball of the plant and place the mock orange at the same depth as it was in the container. Backfill the hole with soil, ensuring that the plant is upright and firm. Water thoroughly after planting to settle the soil.


While Philadelphus Coronaries is relatively drought-tolerant, regular watering is essential, particularly during dry spells or hot summer months. Water deeply, allowing the water to penetrate the root zone. Avoid overwatering, as this can lead to root rot and other moisture-related issues. A layer of mulch around the base of the plant can help retain moisture and regulate soil temperature.


Pruning is an essential part of mock orange care, as it helps maintain the plant’s shape, promotes healthy growth, and enhances flowering. Prune mock orange immediately after flowering, as it blooms on old wood. Remove any dead, damaged, or crossing branches, and thin out the center of the plant to improve air circulation. Avoid heavy pruning, as this can reduce flowering potential.


Mock orange generally does not require heavy fertilization. However, applying a balanced, slow-release fertilizer in the spring can help promote healthy growth and abundant flowering. Follow the manufacturer’s instructions for application rates and timings.

By following these cultivation and care tips, you can ensure that your mock orange thrives and adds beauty to your garden for years to come.

Keep the soil consistently moist and place the container in a warm location with indirect sunlight. Germination may take several weeks. Once the seedlings have grown to a suitable size, transplant them into individual pots or the desired planting location.
  • Cuttings: Take softwood cuttings from a healthy mock orange plant in the early summer. Select a stem that is approximately 4 to 6 inches long and remove the lower leaves. Dip the cut end in rooting hormone and plant it in a container filled with a well-draining rooting medium, such as perlite or vermiculite. Keep the cuttings in a warm, humid environment with indirect sunlight. Rooting should occur within a few weeks. Once rooted, transplant the cuttings into pots or the garden.
  • Layering: Layering is another effective method of propagating mock orange. Select a low-growing branch and bend it down to the ground. Make a small incision on the underside of the branch and secure it to the soil using a U-shaped wire or a small rock. Cover the wounded area with soil, leaving the tip of the branch exposed. Keep the soil moist, and roots should develop within a few months. Once roots have formed, detach the new plant from the parent plant and transplant it to its new location.
