Reviving Leggy Annuals in Florida: When and How to Cut Back

Mid-Season Rejuvenation for Tired Annuals

If your annuals have grown long and stringy after five months in a South Florida garden, a strategic haircut can bring them back to vigorous bloom.

General Rule: Cut Back by Half to Two-Thirds

Most annuals respond well to hard pruning, pushing out fresh growth and new flower buds within weeks.

Consider Temperature Preferences

• Cool-season annuals (alyssum, million bells, ageratum) will take off now that winter temperatures have arrived.
• Warm-season annuals (zinnias, marigolds) may struggle in cooler weather.
• Petunias and impatiens often rest briefly, then explode with new growth and flowers.

Aftercare

Water well first, then apply a mild liquid fertilizer. Continue fertilizing according to label directions. The result: bushier plants and a second wave of color.
