Therefore, it is recommended to plant Philadelphus texensis Hu var. coryanus Hu where it will receive at least six hours of direct sunlight.
Soil Requirements
The ideal soil for Philadelphus texensis Hu var. coryanus Hu is well-draining sandy loam soil. However, it can also grow in rocky soils that are well-draining. It is crucial to ensure the soil is not saturated with water to prevent root rot. Adding organic matter such as compost will help the soil retain moisture and provide nutrients to the plant.
Temperature Requirements
Philadelphus texensis Hu var. coryanus Hu can grow in a wide range of temperature conditions. However, it prefers moderate temperatures ranging from 50°F to 70°F. The plant can handle temperatures as low as 20°F and high as 100°F, but extended periods of extreme temperatures can cause stress and damage to the plant.
Water Requirements

Water deeply once or twice a week or more frequently during prolonged dry spells. Water the plant at the base, avoiding the foliage to prevent fungal diseases and improve water uptake.
Fertilizer Requirements
Philadelphus texensis Hu var. coryanus Hu does not require much fertilization. Adding organic matter such as compost or manure or applying a balanced fertilizer once in the spring can provide the nutrients the plant needs. Avoid over-fertilizing the plant, as it can cause foliage growth at the expense of flowers.

Cultivation
Philadelphus texensis Hu var. coryanus Hu, commonly known as Texas Mock Orange, is a shrub species that grows best in well-drained soil and full sunlight. It is native to Texas and can grow up to 2-3 meters tall with a spread of 2 meters.
The plant is drought-tolerant and can withstand hot and dry weather conditions, making it suitable for growing in arid regions. However, it grows better with occasional watering in dry seasons.
Watering Needs
Philadelphus texensis Hu var. coryanus Hu requires moderate watering. The plant should be watered immediately after planting, after which it should be given enough time to establish itself. Once established, the plant requires watering in dry seasons, preferably once or twice a week.
It is advisable to water the plant early in the morning or late in the afternoon to avoid evaporation, which can lead to water stress and damage to the plant.
Fertilization
Fertilization should be done once per year at the beginning of spring with a balanced fertilizer to enhance flowering. The fertilizer should be well-balanced, with equal amounts of nitrogen, phosphorus, and potassium.
The quantity of fertilizer to be applied depends on the size of the plant and the soil nutrient levels. It is advisable to avoid excessive fertilizer use, which can lead to fertilizer burn and root damage.
Pruning
Philadelphus texensis Hu var. coryanus Hu requires regular pruning to maintain its shape and promote healthy growth. The best time to prune the plant is right after flowering.
During pruning, remove the oldest stems to promote new growth and the development of new shoots. Avoid pruning more than one-third of the plant, as this can weaken the plant and reduce its vitality.
It is also advisable to remove any dead, diseased or damaged branches immediately to prevent the spread of disease or pests.
Propagation of Philadelphus texensis Hu var. coryanus Hu
Philadelphus texensis Hu var. coryanus Hu, commonly known as Texas Mock Orange, is a deciduous shrub native to Texas and Louisiana. It's a beautiful plant with fragrant white or pale pink flowers that bloom in late spring or early summer. The plant can grow up to 5-8 feet tall with a spread of 6-10 feet. Philadelphus texensis Hu var. coryanus Hu can be propagated by several methods which include seed sowing, stem cuttings, and layering.
Seed Sowing
Philadelphus texensis Hu var. coryanus Hu can be propagated from seeds, but it's not the most reliable method of propagation. Seeds should be collected from mature fruits in the fall and sown in a well-draining soil mix in the spring. The seedlings should be kept moist and in a warm location, and once they have grown to a reasonable size, they can be transplanted into individual pots.
Stem Cuttings
Stem cuttings are the most common method of propagating Philadelphus texensis Hu var. coryanus Hu. The best time to take cuttings is in late spring or early summer when the plant is actively growing. Cuttings should be taken from the current season's growth and should be around 6 inches long. Remove the lower leaves, dip the cut end in rooting hormone, and plant in a well-draining soil mix. Keep the cuttings moist and in a warm, bright location until they root. Once roots have formed, the cuttings can be transplanted into individual pots.
Layering
Layering is another method of propagating Philadelphus texensis Hu var. coryanus Hu. In late spring or early summer, select a low branch on the plant and bend it down to the ground. Remove the leaves from the section that will be buried, and make a shallow cut on the underside of the branch. Dust the cut with rooting hormone, and cover the section with soil. Keep the soil moist, and once roots have formed, the branch can be severed from the parent plant and potted up.
Disease and Pest Management for Philadelphus texensis Hu var. coryanus Hu
