"wait, wait...are you saying I can put six HUNDRED plants in a 10x10 plot???" Those yields are based upon a degree of soil conditioning that is very labor-intensive... and while I have read of such recommendations, I have yet to see photos, or hear first-hand observations, proving that they would work for most gardeners. All of the digging aside, in my area, I'd be flirting with disaster if I crowded my beans that closely. Personally, I wouldn't recommend it. Most bush beans - when healthy & mature - have a footprint of 1/2 - 1 sq. ft. or larger. 100 plants (1 per sq. ft.) should be a safe bet; I've successfully used 6" between plants w/ 2-foot spacing between rows, which is close to the same thing. You might be able to get away with 2-3 plants per sq. ft. for the more compact varieties. Crowding more closely than that may work in the warm dry climate of California; but in the cooler, wetter Northern climes, it could lead to severe disease problems. I'm not saying that it wouldn't work... just that I wouldn't put all my eggs in that one basket, unless/until small-scale trials proved it to be successful. In a post above, I had mentioned "seed efficiency". To put that in perspective, large kidney beans are somewhere in the neighborhood of 40-60 seeds per ounce. If planted at the recommended bio-intensive density of 600+ for a 10' X 10' plot, you would need between 10-16 ounces of seed to plant... so you would need to buy (or save from the previous season) a pound of seed. Assuming you harvest 24 pounds of dry seed (which is, keep in mind, the best case scenario), it would represent a return of between 24/1 & 38/1, depending upon seed size. Most gardeners would get much less than that, since the maximum is for experienced gardeners, on well amended soil. In contrast, my observations are that large-seeded bush beans, given the 6" plant/2' row spacing I mentioned above, are easily capable of a seed increase of between 50/1 - 100/1. Small-seeded types will tend to yield about the same weight/plant, but at an even higher ratio of increase, well over 100/1... so in terms of cost effectiveness (if purchasing seed) small is often better. Pole beans can do better still; the "Striped Cornfield" I grew this year (@45 seeds/oz.) produced a return of over 500/1! My results were obtained by mechanical tilling, with leaves & mulch turned under each season. Using these numbers, the same kidney beans - if grown in 5 rows in the same 10' X 10' plot - would be 100 plants. This would produce between 5 & 10 pounds of seed minimum... with only 2 ounces of seed required for planting, the average in a packet of beans. Also, at this spacing, the plants have sufficient air flow through the foliage to minimize the chances of disease during prolonged periods of rainfall. Having tested that theory in some very bad years recently (such as in 2008) I consider these yields to be realistically attainable, year after year. I don't doubt that my spacings could be improved upon; it is something that I often experiment with. Most likely, there is a happy medium somewhere between row spacing & high-density plantings which will produce the best yield, for a given area, with the littlest possible seed. That "happy medium" should take into account the expected annual variations in climate, since what works well one year, might not work the next. With soybeans, I have had some success with closely-spaced double rows, with standard row spacing between the pairs... so that may work for bush beans as well. Given the observations I have made on over 100 bean varieties over the years, I expect the optimal spacing will vary widely, depending upon variety, climate, and soil fertility. So there is really no "one correct answer" for bean spacing... just starting points for personal experimentation. Keep in mind, John Jeavons' bio-intensive recommendations mentioned above pertain to bush beans only. Pole beans are not suitable for wide bed planting, due to shading. However, you can have the best of both worlds using pole beans. Planted in a single row on the North side of the bed (where they would not shade shorter crops), they take up a relatively small footprint. A high-yielding pole variety could give you 3-4 pounds of dry seed from one row in that same 10' X 10' bed. You could use the majority of the bed(s) for other things, and still get a good crop of beans. My apologies for all of the long (and probably dry) posts, but as an amateur researcher, I just wanted to share some "bean science". Just wish this was on the Bean Forum.

For less than the cost of stamps, you can easily get those seeds. Try the dollar store. My friend got 3pkg. for $1.oo for a project with her class.

I don't have very many varieties yet, but beans are what got me started on heirlooms." and "I was so excited to see the bubble envelope in the mail today, but .... nothing left inside but my list. :-(" Now that there is a damn shame, as they say. I would be more than happy to share some of my bounty from this swap. Mchill320 did an awesome job, and it will be years before I could grow them all. If interested, send me your mailing info (and your wish list, if you want) and I'll see what I can do. Rick This post was edited by rdback on Mon, Jan 13, 14 at 15:57

I'll give you points for growing bitter melon. ;-) Sorry so late, this forum is so inactive now compared to the good ole' days of Gardenweb that I seldom check it. As another long-time member (the year of membership is one of the many things removed) I too miss those golden years when this was a vibrant trading platform. You might not have anything that I want (other than possibly the bitter melon) but take a look at my trade list. It's still here, although I'm not sure its visible... if you can't find it on my member page, it is also copied as one of my Idea Books.
