DETAILS

Care Instructions
Ceanothus tomentosus requires bright, direct sunlight for optimal growth. It prefers moderate temperatures and can tolerate dry conditions. Watering should be infrequent, allowing the soil to dry out almost completely between waterings. This plant does well in moderate humidity levels.
Soil
This shrub prefers well-draining loamy soil. It can tolerate poor soil conditions but thrives best in soil that is not overly rich in nutrients. Good drainage is essential to prevent root rot.
Fertilizer
Ceanothus tomentosus generally does not require fertilization. If necessary, a light application of a balanced fertilizer can be used sparingly during the growing season.
Repotting
Repotting is not typically required for Ceanothus tomentosus as it is primarily an outdoor shrub. However, if grown in a container, repotting should be done in the early spring before new growth begins.
Propagation
Propagation of Ceanothus tomentosus can be done through seeds or semi-hardwood cuttings. Seeds should be sown in the fall, while cuttings can be taken in late summer. Ensure the cuttings are kept in a humid environment until roots develop.
Pruning
Pruning is recommended to maintain the shape and health of the shrub. It should be done in late winter or early spring before new growth starts. Remove any dead or damaged branches and thin out dense areas to improve air circulation.
Toxicity
Ceanothus tomentosus is not known to be toxic to pets or humans. It is generally considered safe to have in gardens and landscapes.
Additional
Ceanothus tomentosus is drought-tolerant once established and can be a great addition to xeriscape gardens. It attracts pollinators such as bees and butterflies, making it beneficial for the local ecosystem.
