Regarding fertilizer, usually the plant does not need much. If you find that the leaves are turning yellow, this may be a sign of over-fertilization. It's best to err on the side of under-fertilizing. As for the roots, they are very hearty and can withstand a lot of abuse.

Pruning is an important part of keeping your mock orange healthy and looking its best. Pruning in late winter or early spring will help to encourage new growth and prevent the plant from becoming overgrown. When pruning, be sure to remove any dead or damaged branches. You can also thin out the plant to improve air circulation and allow more light to reach the inner branches.
Propagation for the Mock Orange is best done through softwood or semi-ripe cuttings in late summer or early fall. The cuttings should be taken from new growth that has not yet hardened off, and they should be about 4-6 inches in length. The cuttings should be placed in a moist potting mix and kept in a sheltered location that receives indirect sunlight. The cuttings should be misted regularly to keep the soil moist, but not soggy. After a few weeks, the cuttings should develop roots and can be transplanted into their own pots.
Usually, the plant growth rate is determined by the soil fertility, drainage, temperature and water availability. The best time to plant lewis mock orange is in early spring before the last frost date. Lewis mock orange can tolerate a range of soil types but prefer well-drained, slightly acidic soils with a pH of 6.0 to 7.0. Lewis mock orange is also tolerant of drought and salt.
