How to Grow Phlox Plant Outdoors

Phlox plants are a popular choice for gardeners looking to add color and fragrance to their outdoor spaces. These versatile plants come in a variety of colors and can bloom from spring to fall, making them a great addition to any garden or landscape. Whether you’re a seasoned gardener or a beginner, growing phlox plants outdoors is relatively easy with the right knowledge and care. In this article, we will discuss the steps to successfully grow phlox plants outdoors.

Choosing the Right Variety

The first step in growing phlox plants outdoors is choosing the right variety for your garden. There are several different types of phlox plants available, including tall garden phlox (Phlox paniculata), creeping phlox (Phlox subulata), and woodland phlox (Phlox divaricata). Each variety has its own unique characteristics and growth habits, so it’s important to choose one that suits your specific needs.

Tall garden phlox is known for its tall flower spikes and comes in a wide range of colors. Creeping phlox, on the other hand, is a low-growing variety that is perfect for ground cover or cascading down walls or slopes. Woodland phlox thrives in shady areas and is often used in woodland gardens or under tree canopies. Consider the location, soil conditions, and sunlight exposure in your garden before selecting the appropriate variety.

Finding the Right Location

Once you have chosen the right variety of phlox plant, it’s time to find the perfect location for it in your garden. Most phlox plants prefer full sun to partial shade, so look for an area that receives at least 6 hours of direct sunlight per day. However, woodland phlox can tolerate more shade than other varieties.

In terms of soil conditions, phlox plants prefer well-drained soil that is rich in organic matter. Before planting, amend the soil with compost or well-rotted manure to improve drainage and fertility. Phlox plants are also sensitive to waterlogged conditions, so make sure to choose a location that does not have standing water after heavy rain.

Planting and Care

Phlox plants can be grown from seeds, cuttings, or transplants. If you choose to start from seeds, sow them indoors 6-8 weeks before the last frost date. Once the seedlings have developed their second set of true leaves, they can be transplanted outdoors.

If you prefer to use transplants, purchase healthy young plants from a reputable nursery or garden center. Before planting, prepare the soil by removing any weeds and loosening it with a garden fork or tiller. Dig a hole that is slightly larger than the root ball of the plant and place the phlox plant in the hole. Backfill with soil and gently firm it around the base of the plant.

Water the newly planted phlox thoroughly and continue to water regularly, especially during dry spells. However, avoid overwatering as this can lead to root rot. Mulching around the base of the plant can help retain moisture and suppress weed growth.

Pruning and Maintenance

Phlox plants require minimal pruning but benefit from deadheading to promote continuous blooming. Deadheading involves removing spent flowers by cutting them back to the nearest set of healthy leaves or lateral bud. This encourages the plant to produce new blooms and prevents self-seeding.

In late fall or early spring, cut back the foliage of tall garden phlox to approximately 6 inches above ground level. This helps rejuvenate the plant and promotes healthier growth in the following season.

Dealing with Pests and Diseases

While phlox plants are generally resistant to pests and diseases, they can occasionally be affected by powdery mildew, spider mites, or aphids. Powdery mildew appears as a white powdery coating on the leaves, while spider mites and aphids can cause damage by feeding on the plant sap.

To prevent these issues, make sure to provide adequate air circulation by spacing out the plants and avoiding overhead watering. If powdery mildew does occur, treat it with a fungicide labeled for phlox plants. Spider mites and aphids can be controlled by spraying the affected plants with insecticidal soap or horticultural oil.

Conclusion

Growing phlox plants outdoors can be a rewarding experience for gardeners of all skill levels. With their vibrant colors and delightful fragrance, phlox plants add beauty and charm to any garden or landscape. By choosing the right variety, finding the perfect location, and providing proper care, you can enjoy the beauty of phlox plants in your outdoor space.
