Phlox Planting Guide:

Phlox are best planted in spring, and are usually shipped as potted plants. Plan to plant your phlox immediately upon receiving them, so that they don't dry out or become rootbound. Keep your plants' soil moist if you must wait to plant.

Before planting, choose the best possible location for your plants. Many phlox varieties are susceptible to mildew, and, like other perennials, they don't like consistently wet roots. Plant your plox in a sunny, airy location where water does not tend to pool. Be sure to check the spacing needs for your variety of phlox. Most creeping phlox should be planted 12 to 18 inches apart and grow only 6 inches tall. Tall phlox can grow upwards of three feet in height, so be sure to choose a site that allows for appropriate space in both width and height.

Before planting, prepare your soil. While phlox are amenable to many soil types, they'll do best in nutrient-rich, airy soil with good drainage. Till your area well, using a garden claw or hoe. Then, mix in topsoil or compost to add drainage and organic matter. Now, your phlox can be planted at the same depth to which they were potted.

Phlox Care Tips:

Phlox plants are considered one of the easiest to care for-they are low-maintenance, and typically only require watering. They do well with other plants and are not invasive. Follow our recommendations below on how to water, prune, and protect your phlox plants from pests and diseases.

Phlox Watering Recommendations

Keeping a well-watered soil for phlox plants is essential. If your garden receives less than one inch of water per week, it is recommended to water phlox plants regularly during the high-temperature months of the spring and summer. Watering should be done in the morning so that moisture can dry off during the day. Make sure to water your phlox plants at the root zone rather than overhead, to keep the foliage healthy.

Phlox Pests & Diseases Care

Phlox plants can be susceptible to pests such as powdery mildew, leaf spots, caterpillars, and leaf miners. The issue is more common in areas that have humid and warm summers, particularly with plants growing in part shade. The best way to prevent pest issues with phlox plants is to leave space between the plants to allow for good air circulation. Diseased plants should be regularly removed to prevent the spread of this issue.

Phlox Pruning Tips

Phlox plants don't require pruning, as the plants die back after each growing season. You can trim your phlox back to an inch or two of stem height after the first frost of the year.

Through the growing season, you shouldn't need to cut phlox. but you can cut them back as needed for desired shape and size. You may find that your creeping phlox need a trim if they are being used as border plants. You can trim any parts that are hanging on the sidewalk or the driveway. You can also cut the phlox plants to keep them in a neat form.

Phlox plants can be a great addition to any garden. Thanks to their low care needs, they're the perfect plant for any beginning gardener. But these aren't just hobbyist's plants. Phlox's reliability makes them a favorite of professional landscapers and experienced planters, too. Try phlox, and you'll quickly see why!
