I live in Alabama and my pole limas are not blooming.
If they are healthy but not blooming, they likely have too much nitrogen. Give them some phosphorus to balance them back out. Bone meal is a good source of phosphorus.
What month do you plant butter beans?
You didn't indicate your USDA hardiness zone. Planting month varies within zones. However, I would imagine that most people plant lima/butter beans in the month of May. The last average frost date for zone 6b is May 15. We plant between May 7 and 21. Hopefully, this article will help: https://www.gardeningknowhow.com/edible/vegetables/beans/growing-butter-beans-in-your-garden.htm
We have lush vines, lots of pods and new blossoms, but the pods are not filling out. I read where excessive heat. . . we did have about 4 days in early July that were 100, but they have had ample water and are mulched with newspaper and wheat straw. Everything we do is organic. If they have had too much nitrogen, is there a way to reverse it? Thanks!
If your foliage is truly lush, yes, the soil might have too much nitrogen. that would require a soil test. Lime will usually reverse an acidic soil. You might also have a longer to mature butter bean. Do you see bees? If not, pollination might not be happening. If you need information on soil testing, call your local agricultural extension office.
I'm growing speckled pole limas in Gainesville, FL. They produced like crazy a couple years ago in a different part of town. They're inoculated with a garden combination mix in a strip of land where we dug out bahia grass and mixed in a little low-N horse manure.
I built a huge trellis for them, about 12 feet tall, and they swallowed the whole thing in a few weeks. They've been growing really well for months, look really healthy, but have yet to produce a single bean. We've been getting a lot of rain this summer. They look like they're enjoying it. The pods fall before they've grown much, and the few that stay on till they dry have stunted little beans in them.
I hear there's a boron deficiency in the area; could that be the cause? Cowpeas growing nearby are producing seeds if they escape the scythe long enough to flower (last year's cover crop came back. I'm letting them stay between the rows, but they keep trying to swallow my other crops, so I cut them back regularly. ).
It is possible that the soil has too much nitrogen, consider a soil test. Inquire about that at your local agricultural extension office, or at Department of Horticulture at the university.
If you are using saved seed, it could be possible that they got cross-pollinated last year with a low yielding legume of some sort. Just an idea...
My lima beans have defects. The pod looks fine on the outside, but when opened the bean looks deformed, dented. and is not smooth. Is it a bug or something I can spray?
What you are seeing is possibly a result of water stress. Deformation of bean seed follows too much and/or too little water. The beans are usually still safe to eat
What is the optimum watering technique for lima beans? For example, if I grow them in a greenhouse, how much water should I give them (30 seeds in a planter) and how often? Thanks!
For seedlings, you want to keep them moist so you will need to check them daily. It is best to water from below so that they take water up from the bottom of the pot/cell. This helps keep away harmful fungus. It is hard to say the exact amount of water, as this is influenced by many environmental factors such as humidity and temperature of your greenhouse. The best way is to check them once a day and water as needed.
We planted our lima beans about 3 weeks ago but there is nothing coming up. We also planted our green beans and crowder peas. They all came up. We planted the limas the same as the others but we don't see any sign of life. What could be wrong?
It is possible that the seeds were affected by something and are no longer viable. Being exposed to extreme cold or hot or dampness would do it and could very well have happened even before you bought them.
