Mexican Heather Care: Watering and Blooming Tips

Mexican heather (Cuphea hyssopifolia) is an annual flowering groundcover for full sun and well-drained soil. Water 1 inch every 5–10 days (adjust for heat/rain). After planting, water every 2–3 days for two weeks, then taper off. Deadhead spent flowers to encourage new blooms.

Cover if frost threatens (below 40°F) to extend the season. In Zone 8, it may survive mild winters with protection. Brown leaves often indicate watering issues—too much or too little. Check soil moisture before watering.
