Square Foot Gardening Planting Chart
This chart shows how many plants fit in one square foot, how tall each crop grows, when you can harvest it, and how long the seeds stay good in storage. Use it when you’re laying out your raised bed grid — it takes the guesswork out of spacing so you don’t end up with crowded, stunted plants.
