Square Foot Gardening revolutionized small-space vegetable growing with its grid-based, intensive planting method invented by Mel Bartholomew in the 1980s.
The Method
Divide raised beds into 1-foot squares using string or wood slats. Plant different crops in each square based on spacing: 16 carrots, 9 beets, 4 lettuce, or 1 tomato per square. The intensive spacing maximizes yield per square foot.
Mel’s Mix soil: equal parts compost, peat moss (or coco coir), and vermiculite. The method eliminates row spacing, reduces weeds, and suits small yards, patios, or balconies.
The Revival
Mel Bartholomew’s “All New Square Foot Gardening” (2006, revised 2013) reignited interest. YouTube channels (Garden Answer, CaliKim29) demonstrated SFG builds and plantings from 2014 onward.
The visual grid appealed to beginners: clear spacing rules, organized layout, aesthetic appeal.
Criticism
Critics argued: expensive soil mix, limited root space for some crops (squash, melons), and overly rigid spacing. But for beginners and small spaces, SFG remained popular.
