@pharmerphil -- I am really not sure but I would guess somewhere between 4 and 6 hours.
@elevenplants -- You give me hope
Glad you've been having good luck so far! I have bought lettuce, broccoli, cauliflower, and a strawberry plant (for a different spot next to the house that gets more sun). I bought them Saturday but not planted yet. I have fencing that I still need to staple to the stakes. The lettuce is looking a little limp already so I may need to buy a new plant.
@TZ -OH6 -- Thanks for the tip on the cherry tomatoes. Tomatoes actually did alright last year (although a bit tall and spindly) but the the deer and/or other animals got them before I did.
@petalfuzz -- Thanks for the info. Since I am new to this house and gardening I think I will just try some different things and see what happens!
