Why Full-Sun Container Annuals Become Leggy and Dry

Common causes: old potting soil with residual roots blocking new growth, no drainage holes (causing root rot), evening watering wetting foliage (promotes mildew), overfertilizing or fertilizing dry soil (causes weak growth or burn), and shallow watering that doesn't penetrate the root zone.

Fixes: use fresh soil yearly, ensure drainage, water in morning, fertilize only after deep watering (use time-release + organic granular at planting), and water deeply — if soil pulls away, water twice with a pause between. Check soil moisture before watering.
