If yes, how tall or how long will it take to reach 10 feet tall? Also, I planted a lima bean. It got a stem and leaves. Will it grow edible lima beans?
A lima bean will not grow into a tree. It is a vining annual, so may get several feet tall but will never get woody like trees and will die after a few months.
If you planted a lima bean, then yes, there is a good chance that if it does not die before it is full grown, it will grow more lima beans.
I planted Fork Hook bush lima beans in my home garden; however, they seem to be running. Is this normal? Do I need to stake them?
Obviously, someone must have mislabeled them, as bush beans do not typically behave this way. Beans with runners are known as pole beans and do require some type of support. These articles will help: https://www.gardeningknowhow.com/edible/vegetables/beans/growing-bush-beans.htm
I am making my first attempt at growing Henderson Bush Lima beans. They have been planted approx. 21 days. They are doing very well and are growing fast, but something seems a little odd about them. The plants seem to be growing a "runner" above the main bush, which is 8-10 in tall. Some of the runners are approx 12 in tall. Is this normal? It seems odd for a bush type plant to be growing such a long runner out of the center of the plant.
This is normal. You can make it a bit more bushy by nipping off a 1/4 - 1/2 inch of the end of these runners. This will force them to "bush" out rather than up.
I have a double 50-foot row of pole lima beans. Vines are beautiful, healthy, and green. Spring production has been low. I have sandy loam soil, which I add organic matter to annually. I do not fertilize since I have been told it promotes vine growth and not production. Presently I have very few blooms. What can I do to promote fall production since vines are very healthy. I have very few bees. Will fertilizer or lime help?
From your description poor pollination is your problem. Try planting additional plants and flowers that attract pollinators to help with that issue. You might also want to research using Mason bees for your garden. They are great pollinators and do not sting. There are bee houses and bedding available both commercially and you can make your own.
You have been misinformed about using fertilizer. Plants need it to grow, you get too much vine from to much nitrogen in the soil, normally it's from over fertilizing. More is NOT better when you are apply this amendments. By adding additional organic matter I'm sure you are getting most of your fertility from that, but when in doubt, don't guess, soil test.
How do I store fresh lima beans?
You can store fresh picked lima beans at about 32 degrees F. with 90% humidity for about two weeks. You can also freeze them or can them, depending on your preference.
I have lived at several locations in this area. Always same problem with limas. Nice plants, lots of blossoms, few beans.
