Maybe a silly question but...

I am new to gardening and live in a townhome in a master-planned community where we can rent garden plots for the growing season. My choices are limited and the spot I have is about 80 sq ft. without a raised bed frame. They bring in garden soil from a company that delivers it in a giant bag but I don't have any information about which exact product it is. I am waiting for more info on that. BUT my question is, is there a way to sort of modify SFG to fit a situation like this? What can I take or leave? This stuff is what keeps me from getting started with gardening. I find it so overwhelming.

Adam,  Community gardens can be limiting to those who would like to fully use the SFG method.  I would borrow from the book everything within your control such as lots of pure composts for feeding the plants, trellising/staking everything that vines or need support to stay upright, grid so you plant at a comfortable spacing (not too close, not too far apart), adding more composts for the next planting, NOT walking on the soil or planting a hand on it for balance.

A 10'x8' plot can have a 2' wide "walking path" or aisle down the middle.  That will allow you to walk around the two 4' x 8' "beds" and reach everything.  The measurements of the plot will determine the final size of each half. If you can't "frame" your plot and the 2 beds I'm recommending you create, maybe you can use stake and string for the beds and the grids.

These photos show the bare plot and the finished beds created in the plot at a community garden.
