So that black tarp has been down for a few days, if it wasn't raining I would be out planting today.
Plan out the winter garden, make sure that your taller items are on the north side of your garden.
Punch a small hole into your landscaping tarp and drip your seed into the soil. Water and mulch around everything.
Wait for it to sprout, then mulch closer in, around the newly formed plants. Make sure that your plants are cool weather hardy. Water like you would with your summer garden, keep that bitter north wind off of them, and things should be fine.
