The best soil is potting soil for a Lima bean growth.
Yes lima beans can grow without soil but it's not the soil that makes the difference it is what is in the soil................................ the nutrients.
soil
Beans prefer soil that is near neutral in pH. 6.0 to 6.8 is preferred. So lima beans prefer a slightly acidic soil.
the best soil is loamy
You can germinate lima beans by putting them between two paper towels, covering them with something that light does not get through like a newspaper and keeping them wet.
in soil, i did a experiment on it and some of the multiple beans died in the soil and the others didn't grow as tall or as healthy as the ones in potting soil. i am now planting the potting soil ones in my garden as the others in the dirt are staying on the window.
which is the best soil for plant growth.
Coffee does not grow lima beans. However, used coffee grounds can help lima beans grow properly. When combined with fertilizer and other soil additives, coffee grounds can help create a well-drained, organic loam soil that helps lima beans thrive.
Because of their large size, lima beans are great for watching as they sprout. Give each student a plastic baggie, preferably with a ziploc-type top. Each student places a couple of dry lima beans in her bag. She then adds a little water and closes the bag. Write each child's name on his bag with a permanent marker, and tape the bags to a window that gets a lot of sun. As the days progress, you will observe sprouts emerging from the lima beans. Tell your students that this is what happens when the seeds are planted in the earth. The sprout would eventually poke through the ground, and grow, and become a plant that would produce more lima beans. An optional step two is to take new, dry lima beans and plant them in soil in cups. Keep those in the window and let your students water them daily. It is exciting to watch the sprouts emerge from the soil, just as they watched sprouts emerge from the seed itself.
The amount of time it takes for a lima bean to grow depends on several factors; depth of seeds in the soil, temperature of the soil and the condition of the soil. Seeds start to germinate at about 5 days and can be 5 inches tall in just a little over a month.
Loamy well drained
Enough to keep the soil moist, for healthy plant growth.
