broad-leaf mock orange

For best results, water the broad-leaf mock orange (Philadelphus pubescens) once a week or more when the top several inches of soil is dry. Water until the soil is saturated, and then allow it to drain. To avoid root rot, do not keep the soil overly wet. During hot and dry periods, a supplemental watering may be necessary. Increase the amount of water during warmer months and decrease during the winter. Additionally, mulch around the base of the plant in order to help the soil retain moisture.

The broad-leaf mock orange (Philadelphus pubescens) requires full sun to partial shade, meaning it should receive at least 6 to 8 hours of direct sunlight every day. This plant species is particularly hardy and does well in hot, dry conditions. During the peak growing season, it is best to aim for at least 8 hours of direct sunlight. This ensures healthy growth and full, vibrant blooms. When the temperatures are particularly hot, it is important to shield the plant from full sun in the afternoon. If possible, provide it with some shade during the hottest parts of the day.

Broad-leaf mock orange (Philadelphus pubescens) should be pruned every year to keep the plant healthy and promote healthy growth. Prune the species in early spring before any new growth begins. The best time is usually late February - early March. Prune away any dead, broken, or diseased branches, and thin canopy density if necessary. With older plants, avoid pruning too much of the old wood, as this can result in reduced flowering. Cut branches back to leaf nodes or buds to encourage bushier, healthier growth. Pruning will also help keep the plant size contained and reduce the risk of disease.
