How to Grow and Care for Chickpeas

What we call chickpeas or garbanzo beans are legumes, but they aren’t botanically peas (Pisum sativum). The annual plants are bushy and short. Like tomatoes, chickpeas are indeterminate, they continue to grow new leaves after they have started to flower, in purple, white, pink, or blue colors depending on the chickpea variety. The chickpeas grow in small seed pods. They are green when fresh, though most chickpeas are harvested after the seeds have dried on the plant and turned tan or brown. Chickpeas are widely used in Mediterranean, Middle Eastern, and Indian cuisine.

Chickpeas are planted in the spring and harvested in the late summer after a long growing season. However, you don’t need to live in a tropical climate to grow your own chickpeas for hummus; in fact, chickpeas prefer moderately warm summers.

How to Plant Chickpeas

When to Plant

Chickpeas are planted when the soil temperature in the spring has warmed up to at least 50°F. After that, they need a long, warm growing season. If you live in a cold climate, you should get a head start on the outdoor growing season to increase the chance that the plants reach maturity before the end of the summer. Start chickpea seeds indoors two to four weeks before your average last frost date, as long as you use coir or paper pots that let you transplant them into the garden without disturbing the roots.

Selecting a Planting Site

A location in full sun with well-draining, fertile soil is a must for chickpeas. Make sure you follow crop rotation rules and don’t plant chickpeas in the same place where you grew other legumes the year before.

Chickpeas lend themselves to outdoor container-growing on a sunny patio or porch.

Spacing, Depth, and Support

Plant the chickpeas 4 inches apart. The planting depth varies, 1 inch for small-seeded and 2 inches for large-seeded varieties. Chickpeas are bush-type plants and by planting them densely they support each other, making staking or trellising unnecessary.

Chickpea Plant Care

When grown in the right conditions, chickpeas don’t require much care, and they are moderately easy to grow.

Light

Chickpeas need a spot that gets six to eight hours of sun daily. In hot southern climates, the plants do better with afternoon shade.

Soil

The soil should be nutrient-rich with plenty of organic matter and have excellent drainage. Chickpeas grow in a pH range from 5.3 to 7, around 6.0 being ideal.

Water

To grow chickpeas, the soil needs to be evenly moist at all times. If it does not rain, give the plants about an inch of water per week in areas with moderately warm summers. In hot climates, they need more water until the top 2 inches of soil feel moist. Water the plants slowly and deeply to reach the roots. Drip irrigation is best.

Temperature and Humidity

Chickpeas need warm weather, but they are not a hot-weather crop; they thrive in daytime temperatures between 70°F and 80°F and nighttime temperatures between 65°F to 70°F. Moderate humidity does not bother the plants. In cool climates, an early fall frost cuts the growing season short if the chickpeas haven’t fully matured yet.

Fertilizer

Chickpeas are nitrogen-fixing legumes, so any fertilizer you apply should be high in phosphorus, potassium, and micronutrients, yet not in nitrogen, which promotes foliage growth. If you start with rich, fertile soil, you might not need fertilizer at all. To avoid overfertilizing, lightly sprinkle some granular organic fertilizer in a circle around the plants every six weeks, taking care not to get fertilizer on the stems.

Pollination

Chickpeas self-pollinate and don’t require insects for pollination.

Types of Chickpeas

The two main types of chickpeas are Kabuli and Desi.

• Kabuli are small- to large-seeded chickpeas and these plants usually are taller than Desi. Kabuli chickpeas have white to cream-colored seed coats and white flowers.
• Desi chickpeas are small and have a tan or brown pigmented seed coat. Desi chickpeas have purple flowers and they mature a week or two earlier than Kabuli chickpeas.
  

Harvesting Chickpeas

Depending on the weather conditions, chickpeas are ready to be harvested in 85 to 100 days after planting, in late summer. You can harvest them when the pods are still small and green and prepare them like snap beans.

The most common way of harvesting them is waiting for the leaves to wither, dry, and brown, then pulling the entire plant, including the roots. Place the plant on a flat surface in a warm, dry, well-ventilated location such as a garage. Let it dry further until the pods start to split and the seeds inside are visible. Remove the seeds from their pods.

Before being stored, the chickpeas must be treated to kill any insects and their eggs. To do this in the oven, distribute the chickpeas in a single layer on a baking sheet and pasteurize them at 160°F for 30 minutes. Or, place the chickpeas in freezer bags and leave them in the freezer at 0°F or below for at least 48 hours. Afterward, store the chickpeas in an airtight container in a cool, dry place.

Harvesting Tip

When harvesting fresh chickpeas, look for the plumpest green pods. They should not have any brown spots on them and they should not be wilting.

How to Grow Chickpeas in Pots

Because chickpea plants are short and bushy, they lend themselves to container-growing. Use a container with large drainage holes and well-draining potting mix. Just like chickpeas in a garden setting, start with more plants and thin out the 3-inch seedlings so you end up with a maximum of four plants per square foot. Also, keep in mind that container plants need more frequent watering and fertilizer applications than plants in garden soil. Feed the plants about once a month with a granular organic low-nitrogen fertilizer.

Pruning

While chickpeas do not require pruning, they need to be thinned out. When the seedlings are 3 inches tall, cut any extra seedlings at the surface level to leave 6 inches of space between each plant. Do not pull out the seedlings like you’d pull weeds because that disturbs and potentially damages the roots of the plants you want to keep.

Propagating Chickpeas

As chickpeas are an annual crop with a long growing season, there is no point in propagating the plant vegetatively to produce new plants in the same growing season. Instead, set aside some chickpeas from your harvest to use as seeds the next year.

How to Grow Chickpeas From Seed

Chickpeas should not be soaked before planting. The use of an inoculant, however, is generally recommended. Treating a legume seed with an inoculant ensures that the correct type of beneficial nitrogen-fixing bacteria is available to the plant when it germinates. Different legumes require different bacteria; in the case of chickpeas, you need Mesorhizobium ciceriorM. mediterraneum. Inoculants are available from garden supply companies.

After you have planted the chickpeas—1 to 2 inches deep and 4 inches apart—water them thoroughly and keep the soil evenly moist. The seeds should sprout within 10 to 21 days depending on weather conditions.

If you have started the seeds indoors, plant them in the garden with their pots when the soil has warmed and any danger of frost has passed.

Overwintering

Chickpeas are an annual crop. The plants die after the harvest, so overwintering is unnecessary.

Common Pests and Plant Diseases

Because chickpea leaves, stems, and pods are hairy andsecrete malic acid, insects tend to leave the plants alone.

Like other legumes, chickpeas are prone to fungal diseases such as Ascochyta blight, Rhizoctonia root rot, Pythium rot, Fusarium wilt, white mold, bacterial blight, as well as certain viruses which are transmitted by aphids. These diseases are often exacerbated by high humidity, hot temperatures, and lots of rain. Prevent spreading problems with proper plant spacing to ensure air circulation and avoid overhead watering.
