When should phlox be planted?

Use a garden fork or tiller to prepare your garden bed. Loosen the soil to about 12 to 15 inches deep, then mix in a 2- to 4-inch layer of compost. It is easier to grow phlox from cuttings/transplants than seeds. Plant phlox in the spring and space the plants 1 to 2 feet apart.

How tall do phlox plants grow?

Garden phlox (Phlox paniculata), also called perennial phlox, grows well in USDA zones 4 through 8. At 2 to 4 feet tall, garden phlox blooms later in the summer with bursts of lavender, white, coral, red and violet, depending on the cultivar.
