Growing notes

Cucumbers are mostly water and they drink hard — aim for a steady 1–2 inches per week, and more during heat or fruiting. Water deeply at the base 2–3 times a week rather than a daily sprinkle; this drives roots down and steadies the plant against dry spells. Keep the foliage dry and water in the morning to discourage powdery and downy mildew. Consistency is everything: erratic wet-then-dry swings turn cucumbers bitter, misshapen, and hollow. A 2–3 inch straw or shredded-leaf mulch conserves moisture and keeps soil temperatures even. Containers dry out fast and may need daily watering at the peak of summer.
