Clarification on spacing
Mel's book says this on spacing: (this is on pg 16 in my copy)
"So, in summary, if plants should be thinned to 12 inches apart, plant one per square foot. Ifplants should be thinned to 6 inches apart, plant four per square foot. If plants should be thinned to 4 inches apart then you can grow nine within the space of that one square foot. If plants are thinned to 3 inches apart, you can grow sixteen in that same square foot. Doesn't it all make sense and seem easy enough?"
On pg 109, a diagram shows bush beans / peas as 9 per sq. foot, or the spacing based on 4" between seedings. The same page has carrots 16/sq ft, because their spacing is at 3".
That's all fine. But I have several pea varieties that I'd like to plant (sugar ann, sugar daddy, and dwarf grey sugar snow are among them), and the websites that sell those seeds are indicating spacing at 2". Mel doesn't have a category for 2" separation.
My math isn't speaking to me today, so how many of these peas should I plant per square foot?
