Creeping phlox typically bloom in late spring or early summer. Tall phlox flowering mid to late summer. If your phlox aren’t blooming, they may not be planted in the right growing environment, need nutrients, or have become overcrowded.
Common Reasons Why Phlox Aren’t Blooming
Phlox prefer sunny conditions. If they are not planted in full sun and not blooming, dig them up and move them to a sunnier spot in your garden. If they have become leggy, cut back on your fertilizer regimen. Fertilize with a balanced formula if you have neglected this task for a few years. Divide them if they have become crowded. Dividing is a great way to rejuvenate an old clump and create new, free plants.
Pruning Phlox Help Them Bloom
Phlox are perennial plants and don’t need pruning to encourage more flowers. Tall phlox die back when exposed to an autumn frost and produce new growth in the spring. Cut creeping phlox back if it has spread and is crowding other plants or spilling out onto walkways. If tall phlox are munched on by a hungry deer, rabbit, or another animal, they may not flower that season but will grow back the following year.
Fertilizing Phlox Help Them Bloom
Fertilize phlox in the spring when new growth begins and when flower buds form to encourage them to bloom more vigorously. Use a balanced, slow-release granular fertilizer or top dress with compost.
How To Get Phlox To Produce More Blooms
Grow phlox in full sun conditions with room for good airflow. Fertilize annually or when the plant’s blossom production decreases. Move plants around the garden if necessary until you find the spot where they flower best.
