Care Instructions
Philadelphus lewisii requires moderate temperatures and prefers full sun to partial shade. It should be watered regularly, allowing the soil to dry out partially between waterings. The plant thrives in moderate humidity and should be protected from extreme cold or heat.Soil
This shrub prefers well-draining loamy soil with a slightly acidic to neutral pH. It can tolerate a range of soil types but performs best in fertile, well-drained soil. Ensure good drainage to prevent root rot.Fertilizer
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize in early spring before new growth begins and again in mid-summer if necessary. Avoid over-fertilizing as it can lead to excessive foliage growth at the expense of flowers.Repotting
Repotting is generally not necessary for outdoor shrubs. However, if grown in a container, repot every 2-3 years in early spring. Choose a pot that is slightly larger than the current one and ensure it has good drainage.Propagation
Philadelphus lewisii can be propagated by softwood cuttings taken in late spring or early summer. Dip the cuttings in rooting hormone and plant them in a well-draining soil mix. Keep the cuttings moist and in a shaded area until roots develop.Pruning
Prune immediately after flowering to maintain shape and encourage new growth. Remove any dead or damaged branches and thin out crowded areas to improve air circulation. Avoid heavy pruning as it can reduce flowering.Toxicity
Philadelphus lewisii is not known to be toxic to pets or humans. However, as with all plants, it is best to prevent pets and children from ingesting any part of the plant.Additional
Philadelphus lewisii is a low-maintenance shrub that can add beauty and fragrance to any garden. It is also attractive to pollinators such as bees and butterflies. Mulching around the base of the plant can help retain moisture and suppress weeds.REVOLUTIONIZE YOUR PLANT CARE
