Growing notes

Tomatoes want deep, consistent moisture — roughly 1–2 inches per week, more in heat. Water deeply at the base 2–3 times a week rather than a daily splash; this drives roots down and builds drought resilience. Keep foliage dry to discourage fungal disease, and water in the morning. Consistency matters more than volume: erratic wet-then-dry swings cause blossom-end rot and split fruit. A 2–3 inch mulch of straw or shredded leaves conserves moisture and steadies soil temperature. Containers dry out fast and may need daily watering at peak summer. Ease off slightly as fruit ripens to concentrate flavor.
