The Viburnum rhytidophyllum Hemsl. plant requires regular watering, particularly during the summer months.
Water the plant deeply, allowing the soil to become moist but not waterlogged. Avoid watering the plant too often, as this may lead to root rot.
Fertilization of Viburnum rhytidophyllum Hemsl.

Start by removing any dead or diseased wood, and then prune to maintain the desired shape and size of the plant. Avoid pruning more than one-third of the plant's total growth in a single season.
Propagation of Viburnum Rhytidophyllum Hemsl.
Viburnum rhytidophyllum Hemsl. is typically propagated through seeds, cuttings, and layering.
Seed Propagation
Seeds of Viburnum rhytidophyllum Hemsl. can be collected in late summer or early fall once they have ripened on the plant. After collecting the seeds, they should be cleaned, dried, and stored in a cool, dry place until they are ready to be planted.
To plant the seeds, they should be sown in a well-draining potting mix. Keep the soil moist, but not waterlogged, and place the pot in a warm and sheltered area. Germination should occur within 2-3 weeks.
Cutting Propagation
Viburnum rhytidophyllum Hemsl. can also be propagated through stem cuttings. Softwood cuttings can be taken in early summer while hardwood cuttings can be taken in late fall or winter.
The cuttings should be about 4-6 inches in length and should have a minimum of two nodes. Remove the leaves from the lower half of the cutting and dip the cut end into rooting hormone. Then, plant the cutting in a well-draining potting mix and keep the soil moist. Rooting should occur within a few weeks.
Layering Propagation
Layering is another propagation method that works well for Viburnum rhytidophyllum Hemsl. This method involves bending a low-hanging branch to the ground and pinning it down with a stake or rock. The portion of the stem that is in contact with the soil will eventually form roots. After the roots have formed, the new plant can be separated from the parent plant and transplanted.
Propagation through seeds, cuttings, and layering are all viable options for growing Viburnum rhytidophyllum Hemsl. Choose the method that works best for your situation and enjoy watching your plant grow and thrive.
Disease Management
Viburnum rhytidophyllum Hemsl. is a relatively hardy plant that is fairly resistant to disease. However, just like any other plant, it can still be affected by diseases such as Powdery Mildew, Leaf Spot, and Rust. Powdery mildew can be managed by removing infected leaves and increasing air circulation around the plant. Leaf spot can be avoided by not allowing water to sit on the leaves of the plant. Rust can be prevented through proper sanitation practices and avoiding overhead irrigation.
Pest Management
Viburnum rhytidophyllum Hemsl. is susceptible to damage from pests such as scale insects, aphids, and spider mites. Scale insects can be managed through the use of horticultural oil or insecticidal soap. Aphids can be managed by introducing beneficial insects like ladybugs or by using insecticidal soap. Spider mites can be controlled by increasing humidity around the plant and by regularly spraying the plant with water to dislodge the mites.
It is important to note that chemical pesticides should always be used as a last resort, as they can be harmful to beneficial insects and pollinators. When using any pesticide, always follow the label instructions carefully to ensure the safety of both the plant and surrounding environment.
