Grow Lima Beans In Partial Shade

Lima beans are also called butter beans.


Lima beans are members of the vast bean family and native to Peru. The beans, also referred to as butter beans, have been in cultivation in their natural range for over 7,000 years. Lima beans were introduced into the United States in the 19th century and California is the main production center of the legume. Lima bean requirement for sun differs slightly with growth type of the plants. Does this Spark an idea?


Ligtht Requirement


As a warm-season crop, lima beans require temperatures of more than 65 degrees Fahrenheit for effective germination and plant development. All beans generally require full sun exposure for optimal growth. However, the climbing varieties of lima beans tolerate some amount of shade. But even then the plants need six or more hours of direct sun per day.


Required Temperature


Beans are poorly intolerant of frost and require warm and moist soil and air temperature ranging between 70 to 80 degrees Fahrenheit for fast plant and pod development with early maturity. Lima beans are particularly sensitive to weather extremes and very hot weather over 95 degrees affects flower set and pod growth. Seed germination is poor in soil temperature of less than 50 degrees.


Soil Conditions


Lima beans adapt well to a variety of soil types except the ones that tend to crust after irrigation and rain. This crust impedes seed germination. Preferred soil types include muck soils and sandy or clay loam with the recommended pH ranging between 5.5 to 6.5. Avoid planting in very alkaline soil as this affects growth.


Plant Spacing


After selecting a site in a well-lit area with the right soil quality, space the plants adequately to ensure good light and sun circulation. Space the rows of bush type lima beans 2 to 2½ feet apart with three to four plants in every foot of the row. Plant the pole or climbing varieties in rows or hills spaced 3 to 4 feet apart. Provide sturdy trellises for pole beans for the plants to climb.
