If you can, use drip irrigation or a soaker hose under mulch. Tomatoes like consistent moisture at the roots, not random blasts from a hose. It also keeps the leaves drier, which can help reduce disease pressure.
How do I water tomatoes in raised beds during a heatwave?
My raised beds dry out fast and the tomato leaves droop in the afternoon. I don’t know if I should water every day or give them deeper water less often.
Gardeners share practical tomato watering routines for raised beds, heatwaves and avoiding stressed plants.
Answers & Discussion
Mulch is the missing step for many tomato beds. I use straw or shredded leaves around the plants so the soil does not bake. Before mulching, I watered constantly and still had cracked fruit. After mulch, the moisture stayed much more even.
Raised beds dry faster than ground beds, so check the soil instead of following a fixed rule. I water deeply in the morning when the top few inches are dry. Afternoon drooping can be heat stress, but if they are still wilted in the morning, they need water.
