Does Phlox Come Back Every Year?
Phlox is often a hardy perennial that comes back year after year, providing dependable blooms and easy maintenance. However, some varieties, such as annual phlox, complete their lifecycle in a single season and must be replanted.
Once established, perennial varieties can thrive with minimal care, making both types a versatile choice for garden enthusiasts. Learn more about the differences between perennial and annual plants in our blog.
What Month Do You Plant Phlox?
The best time to plant phlox seeds is in early spring after the threat of frost has passed. Depending on your USDA growing zone, planting dates can vary:
-
Zones 3 to 5 typically plant between late April and early May
-
Zones 6 to 8 can start planting as early as March
-
In warmer regions like zones 9 and 10, phlox can be planted in late winter or very early spring.
Planting at the right time allows your phlox seeds to develop strong roots and produce bright summer blooms.
What Should You Not Plant Next to Phlox?
Avoid planting aggressive or fast-spreading plants like mint, bamboo, or certain types of ornamental grasses near phlox. These can outcompete your flowers for nutrients and space. Additionally, invasive ground covers such as creeping jenny can also hinder phlox growth.
Instead, consider these companion plants that thrive alongside phlox:
These plants complement phlox by providing contrasting textures and colors without overwhelming your garden beds.
Does Phlox Like Sun or Shade?
Phlox varieties have different light preferences. Creeping and garden phlox thrive in full sun, while woodland phlox prefers partial shade. Make sure your planting area matches the needs of your selected variety to promote healthy growth.
How Many Phlox Seeds Per Hole?
Plant 2 to 3 phlox seeds per hole to improve germination rates. Ideally, space each hole about 12 to 18 inches apart to give the plants room to spread and prevent competition for resources.
Once seedlings appear, thin them to the strongest plant in each hole, ensuring proper airflow and reducing the risk of fungal diseases. Maintaining this spacing will help your phlox develop healthy root systems and maximize bloom production.
