This year, I'm direct-seeding a lot of cool-season veggies -- spinach, carrots, arugula, chard, beets, etc. Now the weather is starting to warm into the 60s during the day, 40s at night. The surface of the soil is drying out, though it's moist underneath. Should I be watering daily, or can I rely on wicking and the occasional rain to hydrate the seeds until germination?
