• Maturity date – Check seed packet or plant tag to know maturity timeframe, which varies by variety.
• Season length – Ensure your growing season is long enough for chosen bean variety to fully develop.
• Companion plants – Grow lima beans with corn, cucumbers, celery, strawberries. Avoid planting near garlic or onions.

Preparing Soil

• Loosen soil and remove weeds or debris
• Mix in aged compost or manure
• Ensure proper drainage but moisture retention
• Test pH – Lima beans prefer slightly acidic soil, pH 6.0-6.8
• Fertilize if needed based on soil test results
• Consider adding supports for vining pole varieties before planting

Planting Techniques

• Direct sow in garden after danger of frost
• Plant 1 inch deep, spaced 2-4 inches apart in rows
• Water gently after sowing and keep soil moist until sprouting
• Thin seedlings to proper spacing – bush beans 4-6 in, poles 8-12 in
• Protect young plants with floating row covers if cold temps expected

With good care throughout the growing season, lima bean plants will be ready for harvest in 60-90 days depending on variety.

Caring for Lima Bean Plants

Once your lima beans are planted, proper care is crucial for healthy, productive plants. Ensure they get adequate sunlight, soil nutrients and moisture. Control pests and diseases organically.

Harvesting Lima Beans

To enjoy peak flavor and texture from your homegrown lima beans, harvest at just the right stage of maturity. Identify when beans are sufficiently developed and use proper techniques for picking and handling.

Identifying Peak Ripeness

• Check seed packet or plant tag for maturity timeline
• Pods should be plump and firm with good green color
• Beans inside will completely fill pods
• Pods will change from green to yellowish as beans mature
• Pop open a test pod to inspect beans – should be plump but not dried out

Picking and Preparing Beans

• Use hand pruners or scissors to snip pods from plants, retain stem intact
• Avoid pulling or tugging pods to prevent plant damage
• Harvest in early morning when pods are plump with moisture
• Pick every 2-4 days to maximize yields
• Rinse freshly picked beans and remove from pods
• Consume, cook or preserve beans soon after harvest
• Refrigerate raw beans in vented plastic bag for short term storage

Storing Beans

There are several options for preserving lima beans from your harvest for long term storage and enjoyment.

• Freezing – Blanch pods 2-3 minutes, cool, remove beans, and freeze in airtight containers
