I have a 2'x10' raised garden bed and I have planted tomatoes, eggplant, peppers, cucumber, and herbs. I'm in zone 10 (southern California) and the garden gets at least 6 hours of direct sun. I do not plan on installing an irrigation system any time soon.
How often and for how long should I water the garden to ensure the entire root system is watered but isn't being overwatered? How do I know if I'm overwatering?
