I planted a fall crop of bush beans a couple of weeks ago here in NH. We can get a light frost around July 18 so I plan to put a row cover over them about that time. It would be great if you had room for 4 bean plants. Sure, you could blanch and freeze beans (google for directions) as they come in but they are best fresh from the garden. Some varieties continue to produce better than others. If the beans look like fish hooks, the plants aren't getting enough fertilzer. If you don't have enough beans for a meal, consider stretching them by adding something else. Cooked and cooled green beans are good with French dressing and sliced onions, for example. You probably have time to plant kale now since it's very hardy and can withstand some cold weather. I don't know if it will winter over for me because last winter the deer ate mine. I don't think I would wait until September. See how many days to maturity are specified on the seed package. Yes, it will take longer to grow this time of year since the days are getting shorter. Yes, most flowers turn into a fruit or vegetable unless that kind of plant has male and female flowers. Zucchini, for example, have both so only the female flowers produce squash. The are larger with a bulbous base which quickly turns into a squash.

"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.

My own preferences are much the same as Hemnancy's; I prefer pole beans for their size, flavor, and yield... and for the enormous variation available in heirloom varieties. They require more space, but that is not an issue for me. Bush beans, however, have their advantages too... so sometimes (preferences aside) it's a question of which type is most suitable for the location & the intended purpose. It's also worth noting that beans should be considered for more than just snaps. Bush beans Advantages: - Easy to plant, require no support. - They mature more quickly. This makes them better suited for short-season areas, for late planting, and when they will be grown early or late as part of a succession planting. - Generally bear all-at-once, so good if grown for canning in large batches, especially with limited space. - Low profile, so better suited for high-wind areas. - Most popular dry beans are bush varieties. - More wax bean varieties available commercially as bush than as pole. Disadvantages: - Less suitable for kitchen gardens, where a prolonged harvest is preferable. Succession planting every few weeks can overcome this, if space is available to do so. - More vulnerable to damage by slugs and rodents. - Lower yield.* - Generally smaller pod size. - Fewer cultivars available for use as shellies. - Harvest can be uncomfortable, due to constant bending. Pole beans Advantages: - Higher yield*, sometimes enormous. - Generally larger pods as snaps, so less cutting involved for canning. - More varieties available for shellies, including most of the larger-seeded. - Prolonged harvest, good for fresh eating over a long period. Some varieties, though, will have large flushes in a relatively short period of time. - Pods are higher, making them easy to see & pick, with minimal bending. - Less damage from rodents, snails, & crawling insects. Disadvantages: - Require erecting a pole/trellis. Not too tough for a 20-foot row, but 500 feet of trellis can be a chore. - Take longer to bear, making them less suitable for short season areas. (There are, however, fast-maturing varieties like "Goldmarie" and "Early Riser"). - Except for very long-season areas, they occupy the ground for the entire season, so not suitable for succession planting. - Not good for high-wind areas, where poles & vines may be snapped. - While the over-all yield is very high, the yield-per-plant for a given period may be relatively low, so smaller daily pickings. This is only an issue where space is limited. - Few varieties commercially available for dry beans (but many heirlooms). I have also observed that many bean diseases are either caused or aggravated by soil being splashed on the leaves; bush beans seem to be more vulnerable to this. I used the (*) for yield, because with different planting strategies, either bush or pole can be high-yielding: - Pole varieties have a higher yield per plant, and often the highest yield per row foot... but much of this advantage is lost with multiple rows, because of the greater row spacing required due to shading. They are at their best if planted in a single row, at the North side of the garden. My largest yield per row by far was from a row of "Pole 191" snap beans. - Bush varieties, while yielding less per plant, can be spaced more closely... and since shade is not an issue, the rows can be closer together as well. Succession planting can also help overcome the yield gap, since it allows bush beans to time-share a given space with another crop. I think that the best bean strategy is a single row of pole beans on the North side - with a row or two of bush beans directly adjacent on the South side - so as to form one wide row. This gives the best of both worlds, in a relatively small space. Those pole beans, by the way, can include limas or yardlong beans. As for strings, I think there is little difference; there are both pole beans & bush beans, with- and without strings. However, since most breeding going on now is for bush beans, there will eventually be more stringless varieties available as bush. I don't necessarily see "stringlessness" as an advantage, since many varieties that develop strings are stringless when picked young, and have outstanding flavor. "Kentucky Wonder" is a great example of this. Most of the new bush varieties, while stringless, are of the petite style now popular in Europe... takes a lot of picking to get a basket full. No thank you. Give me the 11" pods of "Fortex", or the long pods of "Goldmarie" or "Garafal Oro", any day.
