Phlox carolina L. var. angusta typically grows best in full sunlight. However, it can also tolerate partial shade for a few hours during the day.
Temperature Requirements
The plant thrives best in warm temperatures ranging from 70°F (21°C) to 85°F (29°C). It can survive in lower temperatures, but not below 50°F (10°C). In colder regions, the plant goes dormant in winter, and the leaves die off until the next growing season.
Soil Requirements
The plant prefers well-draining soils rich in nutrients and organic matter. Phlox carolina L. var. angusta can grow in a variety of soil types, including loamy, sandy, or clay soils. However, the soil pH should be slightly acidic to neutral, preferably ranging from 6.0 to 7.0.
Cultivation
Phlox carolina L. var. angusta (Wherry) Steyermark thrives in well-drained soils with a neutral pH level of around 7.0. It prefers a full sun exposure to partial shade. The plant can tolerate short-term drought but needs adequate moisture during extended dry periods. It is essential to select a site that offers good air circulation and sufficient space for the plant to grow.
Watering needs
The plant requires deep watering once a week during summers, and it is better to water in the mornings. Watering should be reduced in the winter season. It is crucial to avoid over-watering as it can lead to root rot, which can be fatal to the plant. The soil should be well-drained to avoid waterlogging.
Fertilization
Phlox carolina L. var. angusta (Wherry) Steyermark requires periodic fertilization to ensure its growth and health. It is preferable to fertilize the plant in the spring season with an all-purpose fertilizer. Be careful about the concentration of the fertilizer and avoid over application as it can damage the plant. It's a good idea to apply a layer of compost around the plant to provide additional nutrients during the growing season.
Pruning
Phlox carolina L. var. angusta (Wherry) Steyermark requires pruning to maintain its shape and promote flowering. It is best to cut back the plant by up to a third in the spring season before new growth emerges. Remove dead and damaged leaves and stems during the growing season to encourage new growth. Deadheading spent flowers can promote new blooms and improve the overall appearance of the plant.
Propagation of Phlox carolina L. var. angusta (Wherry) Steyermark
Phlox carolina L. var. angusta (Wherry) Steyermark is a herbaceous perennial that is commonly propagated through seeds and division.
Seed Propagation
Seed propagation of Phlox carolina L. var. angusta (Wherry) Steyermark is fairly easy and can be done indoors or outdoors. Seeds should be sown in well-draining soil in autumn before the first snow or in spring after the last frost. Cover the seeds with a thin layer of soil and keep them moist throughout the germination process. Germination typically occurs within 14 to 30 days. Once the seedlings develop their second set of leaves, they can be transplanted to their permanent location.
Division Propagation
Division propagation of Phlox carolina L. var. angusta (Wherry) Steyermark is best done in spring or fall when the plant is dormant. Simply dig up the clump of the plant and gently separate it into smaller sections that each have at least one healthy shoot and root system. Replant the separated sections in well-prepared soil with adequate drainage.
Disease Management
Phlox carolina var. angusta is susceptible to fungal diseases such as powdery mildew and Botrytis blight. Powdery mildew causes a white or gray powder-like substance to appear on the leaves, while Botrytis blight causes the stems to rot at the base. To manage these diseases, it is important to promote good air circulation by spacing the plants well and thinning them out if they become overcrowded. It is also essential to avoid overhead watering which can increase humidity levels and promote fungal growth. Additionally, applying a fungicide to the plant can help prevent the diseases from taking hold. Be sure to read the instructions on the fungicide carefully and apply it in accordance with the manufacturer’s recommendations.
Pest Management
Phlox carolina var. angusta can be vulnerable to pests such as spider mites and aphids. Aphids can be controlled using insecticidal soap or neem oil which can be sprayed on the affected plants. Spider mites can be controlled by spraying the undersides of the plant leaves and stems with water to wash them off. Additionally, applying a miticide can help prevent spider mites from infesting the plants. Another pest that can affect this varietal of phlox is the phlox plant bug. This pest can cause distorted growth and discoloration of the leaves. To manage this pest, it is important to remove any plant debris and keep the planting area clean and free of weeds. If the infestation is severe, insecticidal soap or neem oil can also be used.
