Think of the 3/hole as a hill planting system. They really won't compete any more than 1/3" because they each have a similar resource base. They'll find a way to share space and produce a similar crop, but you will find it easier to plant. I was involved in looking at such systems for various crops years ago, and we found the yeilds tend to be similar. The impact is how each system affects management. In your case, you might find it easier to make a hole every 12". It will probably be safer for the plastic mulch as well.

You might consider planting most of your beans one way, then have a short row the other way just to compare.

Subject: [Market-farming] Bush Beans on Black Plastic Mulch

I was just getting ready to put some of Johnny's"Jumbo" bush beans on
black plastic with drip irrigation.

I'm getting mixed information on how to do this.

Johnny's is telling me to put the plants every two inches (1 seed)
(this is from a consultation phone call). University recommendations
have been for 3 plants spaced 12 inches in the rows (rows 15 inches

the 3 inches apart seems so TEDIOUS for planting and 3 plants a whole
(no thinning recommended) seems like it's won't work.

I'm wondering what's worked for folks on this list.

Also, my last planting of beans has been hit pretty hard by bean
beetles, inspite of weekly spraying with pyrethreum  I'm wondering if
anyone is having luck controlling bean beetles (for example: is that
bean beetle bT still off the market?)
