How to Cut Back Annual Phlox
- 1). Examine the plant after its first blooming for any dead, browning or wilted flowers.
- 2). Pinch away dead or dying blooms by gripping between thumb and forefinger at the base of the bloom. The flower should detach itself from the plant easily. Pinching back the old blooms in this manner will promote new growth.
- 3). Look for new buds or sprouting leaves along the stem beneath the blossoms just removed. If there is new growth, cut the stem just above the bud or leaves at a 45-degree angle.
- 4). Check the base and main foliage of the phlox for any signs of mildew or rust-colored pigmentation. If found, cut back the part of the plant that is the carrier of mildew or rust to thin out the plant and provide better circulation. Try to make the cut above a new growth. If no new growth appears along the stem, cut stem below any signs of mildew or rust at a 45-degree angle.
