I think it depends on how deeply your 10 minute watering is soaking in. I stick my finger in the soil as deep as I can and if it's starting to feel dry, then I water. When I do, I run the soaker hose for 30 minutes. (I have raised beds over clay -- this is going to depend on what kind of soil you have.) I've been watering every 3 or 4 days.
This whole weekend, we had passing showers. Everything LOOKED wet and fresh, but when I did the finger test this morning, only the surface was wet -- it was dry underneath, so I watered. So of course, we had 1" rain this evening
I tell my hubby, "I watered the garden so it's sure to rain later on!"
Just as well since the rest of the garden that DOESN'T get watered had a nice drink.
Oh, earlier on, when I was coddling transplants and seedlings, I was watering every day/every other day to maintain constant moisture nearer to the surface, but you want to encourage the roots to grow DEEPER in search of water rather than staying near the surface. Also, you need to water more when the hoses are above the mulch since the mulch will soak up some of the water and less will soak into the soil.
