Philadelphus schrenkii

Mock Orange (Philadelphus schrenkii) is a deciduous shrub native to Siberia and Mongolia. It features white, cup-shaped flowers that have a strong, sweet fragrance and dark green leaves. While the plant thrives in full sun, it can also tolerate some shade. It grows up to 4 feet in height and width and produces showy, fragrant blossoms in late spring. Mock Orange requires regular watering and should be pruned in late winter or early spring to encourage more flowers. This low-maintenance shrub is the perfect addition to any garden, adding texture, color, and aroma.

watering

Mock Orange (Philadelphus schrenkii) should be watered weekly during the growing and blooming season (Spring-Fall). Water deeply to ensure that the soil is completely moistened but not soaked. Water thoroughly, yet avoid getting the leaves wet and try to keep water off the leaves, as this discourages disease. Allow the soil to dry out slightly between waterings. During the Winter, the plant should be watered less frequently, only once every 2-3 weeks, depending on the temperature.

sunlight

The Philadelphus schrenkii, or mock orange, is a deciduous, flowering shrub that prefers plenty of sunlight to thrive. The shrub prefers either full sunlight or dappled shade and the amount and type of sunlight needed will depend on the climate and environment in which it is placed. In cooler climates, mock orange plants will require at least 6 hours of direct sunlight per day. In warmer climates, the amount of sunlight can be reduced to 4-5 hours per day. For maximum flowering, bright, sunny locations are best, although some partial shade throughout the day is also beneficial. It is important to note that too much sunlight can cause the plant to become dry and stressed, so too much direct exposure should be avoided. And, as with most plants, it is important to ensure there is a consistent source of sunlight and to avoid any sudden changes in sun exposure.

pruning

Mock Orange (Philadelphus schrenkii) should be pruned in early spring, just as it finishes flowering. When pruning, it is important to never prune more than a third of the plant at any given time. When pruning, look for dead or damaged branches and remove any that look diseased or unhealthy. Also remove any crossed branches, and any branches that are growing inward rather than outward. If the plant has become too large, it can be pruned back slightly, but it should not be drastically cut back. With light pruning, Mock Orange will stay full and healthy.
