I put a garden in the front yard of my rented duplex this year. Just dug it right into the ground with no fancy anything, using a lot of free fencing wire & posts. Very crude but effective. My neighbor across the street thought it was so cool he came over and offered to water if I ever needed help. (He paid pennance for 5 days in a row a few days later, but will be repaid in veggies)
The yard had been unwatered and neglected for a few years. I added some amendments with a shovel 10 months ago but the seedlings, planted from seed about 3 weeks ago, were struggling.
This morning I mulched around everything with 6 bags of compost / steer manure ($.99 a bag at Home Depot) layed about an inch thick, but not touching the stems*.
It looks like the plants grew 2" just today!
*Beware, I just thought this up and did it without any research and could meet with disaster later.

Today I watched the DVD "The Power of Community, How Cuba Survived Peak Oil".
This is a very hopeful, uplifting documentary that is only 51 minutes long, but packed with great information.
I feel 87% less doomerish than before watching it:)
