  • water dropWater

    The Mock Orange should be watered deeply once a week, providing it with about 1 to 1.5 gallons of water each time. During hot and dry periods, increase the frequency to twice a week ensuring the soil remains moist but not waterlogged. Adjust watering during rainy periods to prevent overwatering. In winter, reduce watering as the plant's water requirements decrease. Always check the soil moisture before watering to gauge the plant's needs.

  • sunLight

    The Mock Orange thrives best in full sun to partial shade conditions. Ideally, it should receive at least 6 hours of direct sunlight daily. An optimal spot would be where the plant is exposed to morning sunlight and receives some afternoon shade, especially in regions with very hot summers.

  • thermometerTemperature

    Mock Orange performs well in a temperature range between 60°F and 80°F, which are typical daytime temperatures for many temperate climates. It can withstand minimum temperatures down to about 20°F, making it hardy in many regions. Avoid placing the plant in areas where temperatures consistently exceed 90°F, as excessive heat may stress the plant.

  • scissorsPruning

    Pruning the Mock Orange is essential to maintain shape, encourage bushier growth, and improve air circulation. Prune right after flowering, as the plant blooms on the previous year's growth. Remove any dead or overcrowded branches, and cut back about one-third of the oldest stems to promote new growth. Prune annually for best results.

  • circleLife cycle

    The common name for Philadelphus lewisii var. gordonianus is Gordon's mock-orange. Its life cycle begins with seed germination triggered by after-ripening requirements, that may include cold stratification. Following sprout emergence, the seedling phase sees the development of a root system and the first true leaves. As it enters the juvenile stage, the plant experiences rapid vegetative growth, eventually maturing into an adult that develops woody stems and a full crown of foliage. The adult plant produces fragrant white flowers in late spring to early summer, which are then pollinated and produce small, four-chambered seed capsules. Once mature, the seeds are dispersed, completing the cycle and beginning a new generation of plants.

      Spring to early summer

    • The most popular method of propagating Mock Orange (Philadelphus lewisii var. gordonianus) is through softwood cuttings taken in late spring or early summer. To do this, select a healthy stem that has new growth and cut a piece about 4 to 6 inches (10 to 15 centimeters) long. The cut should be made just below a leaf node, and the lower leaves should be removed. Dip the cut end in rooting hormone to encourage root growth and insert the cutting into a pot filled with a well-draining soil mixture. Keep the soil moist and place the pot in a warm, bright spot out of direct sunlight. In a few weeks, the cutting should develop roots and can eventually be transplanted into the garden.
