Lima beans (Phaseolus lunatus) are annuals that belong to the legume family. They are cultivated in gardens for their seeds and for use as vegetables. These beans have a high nutritional value, and their seasonal gardening can be easily mastered.
To grow the beans outdoors, sow them approximately 3 to 4 weeks after final frost date in spring. The seeds should be sown when the temperature of the soil reaches 65 degrees Fahrenheit or more for at least 5 days and when it is consistently warm during the day.
To grow the beans indoors, start sowing them at least 2 to 3 weeks prior to the frost date. This will permit their eventual transplantation into the garden.
The lima beans will mature during a warm and long summer. This explains why they are mostly grown in warmer regions. Fertilize throughout the growing season, and do not forget to remove the diseased bean plants. By the end of season, remove all the plants and root balls to prepare for the next season.
Autumn and Winter
Avoid hot weather conditions while planting lima beans. If you are residing in a mild-winter region, sow the beans during autumn. Then you can harvest the beans by winter.
Lima beans are prone to attack by mites, aphids and flea beetles. Periodically clean the garden and keep it free from debris to prevent the retention or overwintering of pests in the garden.
