Can You Grow These Beans at Home and How?

If you want to grow beans from seeds, plant them around spring, April, or in the heat of summer.

The ideal weather for planting seeds is when daytime temperatures are between 60 and 80 degrees Fahrenheit. Make sure the nighttime soil temperatures remain above 55 degrees Fahrenheit.

The plot must receive full sun for at least six hours every day.

Soil Preparation

Use rich, well-drained soil with a balanced pH between 6 and 6.8.

Plant the seeds one inch deep with four to six inches of seed spacing. Keep the rows at least one and a half to two feet apart.

If you have limited space, you can plant the seeds in containers.

You can also try bean plantings, but it’s a tricky process—the roots are quite sensitive. Luckily, with bush beans, direct sowing is easy for beginners.

Roma II beans have moderate water requirements and thrive well with one inch of water once a week.

If Rhizobia populations are low, use inoculants to fix the issue. Rhizobia are microorganisms that form colonies on root surfaces of legumes to fix nitrogen and promote plant growth. Soil inoculants supply these microbes to the soil.


Roma II seeds germinate within five to 10 days. Luckily, the plant doesn’t need any support or too much fertilization.

Although you may find some climbing varieties, they’re more work and need knowledge of and tools for trellising.

If you want to enjoy a long harvest season, make multiple sowings several weeks apart until June.

Roma II is a disease-resistant strain, but you still need to keep an eye out for pests and diseases that target this plant, such as:

You should also watch out for birds that may attack young bean seedlings. You can keep them away by installing nets or row covers.

These bush beans are best when open-pollinated by bees, birds, and other insects.


Bean plants grow from 1.5 to two feet tall and produce mature five to six-inch pods. They are ready for harvest within 55 to 60 days of planting.

You can pick them early if you enjoy fresh beans with a juicy flavor. Or you can wait until the pods are mature and the beans are swollen to enjoy them as green shelling beans.

Life Cycle

Their life cycle is annual, and once you harvest the last of the pods, you need to replant them the following spring.
