Philadelphus pubescens Loisel. var. intectus (Beadle) A.H. Moore typically grows in areas with partial shade to full sun exposure. However, it is best to provide them with filtered sunlight, as direct sunlight for prolonged periods may cause leaf burn.
Temperature Requirements
Philadelphus pubescens Loisel. var. intectus (Beadle) A.H. Moore prefers mild to cool temperature environments. It can tolerate some frosts, but severe cold may cause dieback. The optimal temperature range for healthy growth is between 15°C to 25°C.
Soil Requirements
The plant can grow in a wide range of soil types. However, it thrives best in fertile, well-drained soil with plenty of organic matter. The soil's pH should be within a range of 5.5 to 7.5. It is essential to avoid waterlogged soils as they can cause root rot and other detrimental conditions.
Cultivation Methods
Philadelphus pubescens Loisel. var. intectus is a hardy, deciduous shrub that thrives in well-drained soils with a pH range of 6.1-7.8. It requires full to partial sun exposure for optimal growth and flowering. When planting, ensure that the root ball is planted at the same depth as it was in the pot or nursery container. Proper spacing between plants is also essential to allow for adequate airflow and sunlight penetration.
Watering Needs
While Philadelphus pubescens Loisel. var. intectus is drought-tolerant, it requires watering during extended dry periods to maintain optimal growth and flowering. Water the plant deeply at the base, allowing the water to soak into the soil to the root level. Avoid overhead watering, which can lead to leaf spot and fungal diseases.
Fertilization
Philadelphus pubescens Loisel. var. intectus is a light feeder and does not require heavy fertilization. A balanced slow-release fertilizer can be applied in early spring before new growth emerges. Alternatively, organic compost can be incorporated into the soil at planting time to provide essential nutrients.
Pruning
Philadelphus pubescens Loisel. var. intectus requires minimal pruning to maintain its shape and promote blooming. Prune immediately after flowering by removing any dead or diseased wood and cutting back any overgrown or crossing branches to encourage new growth and maintain a compact habit. Avoid heavy pruning, as this can reduce flowering potential in the following year.
Propagation methods for Philadelphus pubescens Loisel. var. intectus (Beadle) A.H. Moore
Philadelphus pubescens Loisel. var. intectus (Beadle) A.H. Moore can be propagated via both seed and vegetative methods.
Seed propagation
Seeds from mature fruit can be collected and sown in a well-prepared soil bed or in a container filled with a good quality potting mix. The ideal time for sowing is in late fall or early spring when temperatures are cool. Seeds will require stratification for 30 to 90 days prior to sowing in order to simulate the natural winter process.
Vegetative propagation
Philadelphus pubescens Loisel. var. intectus (Beadle) A.H. Moore can also be propagated vegetatively through softwood cuttings, hardwood cuttings, and layering.
Softwood cuttings: Softwood cuttings should be taken from the plant in spring or early summer when new growth is still tender and flexible. Cuttings should be 3-4 inches in length with a ½ inch stem diameter. Dip the cut end into a rooting hormone and immediately plant in a container filled with a well-draining potting mix. Place the container in bright but not direct light and maintain humidity around the cuttings to promote root growth.
Hardwood cuttings: Hardwood cuttings of Philadelphus pubescens Loisel. var. intectus (Beadle) A.H. Moore should be taken in late fall or winter when the plant is dormant. Cuttings should be 6-8 inches in length and should include the previous year's growth. Plant the cuttings in a well-draining potting mix and keep them in a warm and humid environment until growth appears in spring.
Layering: Layering is another method used to propagate Philadelphus pubescens Loisel. var. intectus (Beadle) A.H. Moore. The process involves bending a low branch of the plant to the ground and covering a section of the stem with soil or compost. The branch should be secured in place with a wire or wooden stake. Roots will eventually form at the buried section of the stem and the new plant can then be separated from the parent plant.
