Excellent ideas. I especially like the trellis - morning glory? Sweet pea? Could be great. A quick suggestion about containers to plant in. I don't know whether cost is a consideration for you, but if it is, think outside the box. Lots of things can be planters that were not sold in a garden supply store - use your imagination, yard sales and thrift stores.
I would love to see the results. But that's months away. Could you let us know by starting a new thread when you're ready to share?
