Fava beans, also called broad beans, are one of the earliest crops a US gardener can plant, thriving in the chilly, damp weather that stalls tomatoes and peppers. Gardeners love the plush, cottony pods that split open to reveal big flat seeds nestled in a velvety white lining. The sturdy upright plants also carry fragrant black-and-white blossoms that draw early bumblebees to the garden.

When and how to plant

Fava beans are a cool-season crop that tolerates hard frost, so sow them about 4 to 6 weeks before your last spring frost, or in fall through winter in mild-winter regions like coastal California and the Deep South. They are almost always direct sown because the large seeds germinate readily in cool soil and dislike root disturbance. Plant seeds 1 to 2 inches deep in full sun and loose, well-drained soil that holds steady moisture.

Care

Keep the soil evenly moist, especially once the plants begin to flower and set pods, giving them about an inch of water per week if rain is short. Favas fix their own nitrogen and rarely need feeding in decent soil, though a little compost worked in before planting helps. Space plants 4 to 6 inches apart in rows, and stake or run twine along taller varieties, which can reach 3 to 5 feet and flop in wind or wet weather. Pinching out the growing tips once the lower pods start to form encourages the plant to fill out its pods.

Common problems

Black bean aphids are the most common pest, clustering on the tender growing tips, so pinch off affected shoots and rinse colonies away with a strong spray of water. Chocolate spot, a brown fungal blotching, shows up in damp, crowded plantings, so give plants room for airflow and avoid overhead watering late in the day. Rotating where you plant favas each year and clearing old plant debris helps keep soilborne trouble in check.

Harvest

You can pick young pods whole when they are 2 to 3 inches long and cook them like snap beans, or wait for the classic shelling stage when pods are plump, glossy, and the beans inside feel full but not hard. Snap or cut the pods from the stalk to avoid tearing the stems, working up the plant as lower pods mature first. Harvest before the pods turn leathery and the seed coats toughen for the most tender beans.

Popular Fava Beans varieties to grow

Fava beans are mostly chosen by plant height, bean size, and how cool and long your spring season is. Home gardeners usually want either broad-bean classics for full pods or smaller-seeded types that handle variable weather well.

Growing Fava Beans in containers

Fava beans can grow in containers, especially compact varieties, though yields are usually lower than in-ground plantings. Use a 5-gallon container at least 12 inches deep for one plant, or a 10-gallon pot for two plants, with drainage holes and fresh potting mix. Keep the soil evenly moist during flowering and pod fill, but avoid waterlogged conditions, and use little or no high-nitrogen fertilizer. Choose a dwarf or bush fava type and provide a short stake if wind is common.

Watering & feeding Fava Beans

Give about 1 inch of water per week, increasing slightly during flowering and pod filling if rainfall is lacking. They have average water needs and are less tolerant of drought during bloom and pod development. Water deeply at the base in the morning and use mulch once soil has warmed enough to help preserve even moisture. Drooping in dry soil signals water stress, while saturated ground, yellowing lower leaves, and poor vigor can signal overwatering or poor drainage.

Fava beans are light to moderate feeders and prefer well-drained soil enriched with finished compost. Focus on phosphorus and potassium where soil tests indicate a need, and avoid adding much nitrogen because legumes can supply part of their own nitrogen. Add compost and any soil-test-recommended nutrients before planting, then generally avoid routine nitrogen feeding during the season. A light, balanced side-dressing may help in very poor soil, but too much nitrogen promotes foliage instead of pods. Keep water especially steady from first bloom through pod fill. Plant in a bed with good drainage, since cool, waterlogged soil can slow roots and invite disease.

Saving Fava Beans seeds

Open-pollinated and heirloom fava beans generally come true from seed, but F1 hybrids do not. Leave pods on the plant until they are brown, dry, and rattly, then shell out the hard, dry beans. Dry the beans indoors for an additional one to two weeks, and check them for insect damage before storage. Kept cool, dry, and protected from bean weevils, fava seed generally stores for about 4 to 5 years.

Fava Beans companion plants

Plant fava beans with cool-season lettuce, spinach, radishes, or carrots, which fit beneath or between their upright plants and are harvested on a different schedule. Favas are legumes that fix nitrogen for their own growth, and their roots and crop residues can add nitrogen to the soil after the plants are cut down. Their flowers can also provide early forage for pollinators. Avoid close planting with onions, garlic, and other alliums, which can inhibit legume growth, and avoid dense blocks of other legumes because they concentrate aphids and some shared diseases.
