Garden Math

Based on average harvests per plant for tomato and strawberries, just to keep our family self sufficient in both we would need at least 35 tomato plants (we have 9) and 300 strawberry plants (what can I say, my kids love strawberries and we eat lots of strawberry preserves). Thats 22 4X4 square foot garden boxes just for those two plants. Yikes! Thankfully, we don't need to be totally self sufficient yet, but as we move towards that end we may have to look into a greenhouse, lol.
