3. Prolific Growth: Given the right conditions, this plant can produce lush growth, ensuring a steady supply of fresh leaves throughout the summer.
4. Pest Resistance: Heirloom Malabar spinach is generally pest-resistant, making it easier to grow organically without relying on pesticides.

Planting Heirloom Malabar Spinach

To ensure a successful crop, follow this planting guide on how to grow heirloom Malabar spinach:

1. Choosing a Variety

Heirloom Malabar spinach comes primarily in two varieties: Basella alba (with green stems) and Basella rubra (with red or purple stems). Both are similar in taste and growth requirements, but Basella rubra adds a striking visual appeal to your garden with its red-stemmed vines. Select your preferred variety based on appearance or availability.

2. Selecting the Right Location

Malabar spinach loves sunlight and warmth, so select a location that receives at least 6–8 hours of direct sunlight each day. It’s essential to plant it in a spot where the soil drains well, as Malabar spinach does not tolerate waterlogged conditions. However, if you live in a particularly hot region, a bit of afternoon shade can help prevent leaf scorch.

3. Preparing the Soil

For optimal growth, Malabar spinach prefers a soil pH between 6.0 and 6.5, slightly on the acidic side. Prepare your garden bed by adding well-rotted compost or organic matter to enrich the soil. This plant benefits from nutrient-rich soil, as it promotes vigorous growth and yields better quality leaves. Malabar spinach doesn’t need excessive nitrogen, so avoid adding too much nitrogen-rich fertilizer, which can promote excessive foliage at the expense of leaf quality.

4. Planting Heirloom Malabar Spinach Seeds

Sow Malabar spinach seeds indoors about 6–8 weeks before your last expected frost date if you live in a colder region. Start the seeds in small pots filled with a seed-starting mix. Plant each seed 1/4 inch deep, as the seeds are relatively large and need to be covered with soil. Keep the soil consistently moist, but not soggy, and place the pots in a warm spot with temperatures around 70°F to 80°F for optimal germination.

Alternatively, you can plant heirloom Malabar spinach seeds directly in the garden once the soil has warmed up and the nighttime temperatures are consistently above 60°F. Plant seeds approximately 12 inches apart, allowing ample space for the plants to spread as they grow. Malabar spinach is a climbing vine, so ensure you have a trellis or other support structure in place.

5. Watering and Mulching

Malabar spinach enjoys consistent moisture, but it’s important to avoid over-watering. Water deeply once or twice a week, depending on rainfall and temperature, aiming to keep the soil consistently moist but not waterlogged. Mulching around the base of the plants with straw or wood chips can help retain moisture and regulate soil temperature.

Growing and Caring for Heirloom Malabar Spinach

Once your plants have established themselves, they’re relatively low-maintenance. Here are some tips for keeping your heirloom Malabar spinach healthy and productive:

1. Providing Support

Malabar spinach is a vigorous climber that can reach heights of 6 to 10 feet. Providing a sturdy trellis or other vertical support is essential to encourage upward growth. A trellis not only supports the vine but also prevents the leaves from lying on the ground, reducing the risk of rot and making harvesting easier.

2. Fertilizing

While Malabar spinach doesn’t require heavy feeding, applying a balanced organic fertilizer every 4-6 weeks during the growing season can enhance growth. Avoid high-nitrogen fertilizers, as they may lead to rapid but weak growth. Compost tea or a balanced, slow-release fertilizer works well for heirloom Malabar spinach.

3. Pruning and Harvesting

Pruning encourages bushier growth and prolongs the harvest period. Regularly harvest the leaves and stems when they reach a desirable size, generally about 3–4 inches long. Start picking leaves once the plants are well-established, usually around 50–70 days after planting. Harvesting the leaves frequently also prevents the plant from flowering and going to seed, which can affect leaf quality.

Malabar spinach leaves have a succulent texture, so be gentle when harvesting to avoid bruising. The leaves can be used fresh in salads or lightly cooked as you would with other leafy greens.

Tips for Growing Heirloom Malabar Spinach in Containers

If you lack garden space or want to grow heirloom Malabar spinach in a more controlled environment, containers are an excellent choice. Malabar spinach thrives in containers, given the right care and conditions, and it can be a beautiful addition to patios, balconies, or small outdoor spaces. Here’s what you’ll need to ensure a productive and successful container garden:

• Choose a Large Container: Malabar spinach has an extensive root system and needs ample space to thrive. Choose a container with a minimum depth of 12 inches, and ideally 14-18 inches in diameter, to allow for root expansion and strong growth. Containers made of ceramic, plastic, or fabric pots work well; avoid small pots, as they can restrict growth and dry out too quickly.
• Use a Quality Potting Mix: The right potting mix is crucial for container gardening. Malabar spinach does best in a nutrient-rich, well-draining mix. Choose a high-quality, organic potting mix with added compost or slow-release organic fertilizer to give your plants a healthy start. Avoid garden soil, which can compact in containers, limit root growth, and hold too much moisture, leading to root rot.
• Regular Watering: Containers dry out faster than garden beds, especially in hot weather or windy conditions. Malabar spinach likes consistently moist soil, so be prepared to water daily during hot summer months or whenever the top inch of soil feels dry. Check moisture levels frequently, as both under-watering and over-watering can stress the plant. Mulching the top of the soil with organic mulch or straw can help retain moisture.
• Provide a Trellis or Support Structure: Like in garden planting, Malabar spinach in containers benefits from vertical support due to its vining habit. Install a small trellis, stakes, or a tomato cage in the container to encourage upward growth. Not only will this support the plant as it climbs, but it will also prevent the leaves from trailing on the ground, reducing the risk of disease and making harvesting easier.
• Fertilize as Needed: Container plants rely solely on the nutrients in the potting mix, so a regular feeding schedule is essential. Use a balanced, water-soluble fertilizer every 4-6 weeks or apply a slow-release fertilizer according to package directions. Avoid excessive nitrogen, as this can lead to lush foliage with fewer leaves suited for eating.
• Position in Full Sun: Place the container in a location that receives at least 6-8 hours of direct sunlight daily. Malabar spinach thrives in warm, sunny conditions and needs ample sunlight to produce healthy foliage. If you’re growing indoors or in a low-light area, consider supplementing with a grow light to provide adequate light for growth.

By following these tips, you can create an ideal environment for heirloom Malabar spinach in containers, allowing you to enjoy a fresh supply of greens even in limited spaces. With regular care and attention, your container-grown Malabar spinach will flourish, adding lush greenery and edible beauty to any small space.

Culinary Uses of Heirloom Malabar Spinach

One of the best aspects of growing heirloom Malabar spinach is its versatility in the kitchen. The leaves can be used in salads, stir-fries, soups, and even smoothies.

Storing and Preserving Heirloom Malabar Spinach

Once you’ve harvested a bountiful crop of heirloom Malabar spinach, knowing how to store and preserve it will help you enjoy its fresh, nutritious leaves long after the growing season ends. Malabar spinach is versatile in the kitchen, but its succulent leaves can wilt quickly after harvest, so proper storage and preservation techniques are essential. Here are some effective ways to store and preserve your Malabar spinach to ensure it stays fresh and flavorful.

1. Storing Fresh Malabar Spinach

Malabar spinach leaves are best enjoyed fresh, as they tend to retain their flavor and texture this way. Here’s how to keep them fresh for as long as possible:

• Refrigerate: After harvesting, gently rinse the leaves to remove any dirt or insects, then pat them dry with a paper towel. Wrap the leaves in a slightly damp paper towel and place them in a perforated plastic bag or an airtight container. Store the container in the vegetable crisper drawer of your refrigerator. This method helps maintain the leaves’ moisture and keeps them fresh for up to a week.
• Use Within a Few Days: Although you can refrigerate Malabar spinach for up to a week, it’s best used within a few days for optimal flavor and texture. Unlike hardy greens like kale, Malabar spinach has a more delicate structure and can wilt quickly, so try to use fresh leaves sooner rather than later.

2. Freezing Malabar Spinach

Freezing is a great way to preserve Malabar spinach if you have a large harvest or want to enjoy it outside the growing season. Here’s how to freeze Malabar spinach effectively:

• Blanch the Leaves: To retain the vibrant color, texture, and nutritional content, blanch the leaves before freezing. Start by bringing a pot of water to a boil. Submerge the Malabar spinach leaves in boiling water for 1–2 minutes, then immediately transfer them to a bowl of ice water to halt the cooking process. Drain the leaves thoroughly to remove excess moisture.
• Flash Freeze: Lay the blanched leaves out in a single layer on a baking sheet and place it in the freezer for a few hours. This process, known as flash freezing, prevents the leaves from clumping together, allowing you to use small portions as needed.
• Store in Freezer Bags: Once frozen, transfer the leaves to freezer-safe bags or airtight containers. Label each bag with the date to keep track of freshness. Properly frozen Malabar spinach can last for up to 10–12 months in the freezer, making it an excellent option for long-term storage.

3. Dehydrating Malabar Spinach

If you’re short on freezer space or want a low-energy preservation method, dehydrating Malabar spinach is a fantastic alternative. Dehydrated Malabar spinach can be rehydrated for soups, stews, and other dishes or ground into powder for smoothies and seasonings.

• Prepare the Leaves: Wash and dry the leaves thoroughly. Remove any thick stems, as they may take longer to dehydrate and can add an unwanted texture.
• Dehydrate: Set your dehydrator to a low temperature (around 125°F) and spread the leaves in a single layer on the trays. Dehydrate the leaves for 4–6 hours, or until they are crisp and brittle. If you don’t have a dehydrator, you can achieve similar results using an oven set to its lowest temperature, but monitor closely to avoid burning.
• Store in Airtight Containers: Once dehydrated, store the leaves in an airtight container in a cool, dark place. Properly stored, dried Malabar spinach can last for up to a year. For easy use, consider grinding the dehydrated leaves into a fine powder and storing them in small jars or spice containers.

4. Making Malabar Spinach Purée

Another way to preserve Malabar spinach is by making a purée that can be frozen in small portions and added to soups, sauces, and smoothies for a nutritional boost.

• Prepare the Leaves: Wash and blanch the leaves as you would for freezing to retain their color and nutrients.
• Blend into a Purée: Place the blanched leaves in a blender or food processor and blend until smooth. You can add a small amount of water if needed to help with blending.
• Freeze in Ice Cube Trays: Pour the purée into ice cube trays and freeze until solid. Once frozen, transfer the purée cubes to freezer bags or containers. These frozen cubes can be stored for up to 6 months and are easy to add to a variety of dishes whenever you need a pop of color and flavor.

5. Pickling Malabar Spinach Stems

If you’re interested in using every part of the plant, consider pickling the red stems of heirloom Malabar spinach. The pickled stems make a tangy, crunchy addition to salads, sandwiches, or as a garnish.

• Prepare the Stems: After harvesting, cut the Malabar spinach stems into manageable lengths and wash thoroughly.
• Make a Pickling Brine: In a saucepan, bring a mixture of vinegar, water, salt, and your preferred spices (such as garlic, mustard seeds, and dill) to a boil.
• Pickle the Stems: Place the stems in a sterilized jar and pour the hot brine over them, making sure they are fully submerged. Seal the jar and refrigerate. The stems will need about a week to develop flavor but can last in the refrigerator for several months.

By employing these storage and preservation techniques, you can extend the life of your heirloom Malabar spinach harvest, ensuring you have access to fresh, nutritious greens even after the growing season has passed. Whether you choose to freeze, dehydrate, or pickle, preserving Malabar spinach allows you to enjoy its flavor and health benefits year-round, adding versatility and depth to your culinary creations.

Saving Seeds from Heirloom Malabar Spinach

Saving seeds from heirloom Malabar spinach (Basella alba) is a great way to continue growing this unique and productive plant year after year. Unlike hybrid varieties, heirloom Malabar spinach will produce seeds that grow true to type, meaning the plants grown from these seeds will maintain the same characteristics as the parent plant. Seed saving is not only cost-effective, but it also ensures you always have access to seeds that are adapted to your local growing conditions. Here’s a step-by-step guide on how to save seeds from your heirloom Malabar spinach.

1. Allowing the Plant to Flower and Produce Berries

To collect seeds from Malabar spinach, you’ll need to let the plant flower and produce berries. Malabar spinach typically flowers toward the end of the growing season or when it experiences shorter days. The small, white or pale pink flowers grow along the vine and are eventually replaced by small, dark purple berries. Allow these berries to mature fully on the vine, as immature berries will not produce viable seeds. Keep in mind that when Malabar spinach begins to flower, its leaf production may decrease, so it’s best to start saving seeds from only one or two plants to maintain your harvest from others.

2. Harvesting the Berries

Once the berries are fully mature and have turned a deep purple color, it’s time to harvest them. You can pick the berries individually or cut off entire sections of the vine if there are several ripe berries clustered together. Be gentle during this process to avoid bruising the berries, which can affect seed quality.

3. Extracting the Seeds

To separate the seeds from the berries, place the harvested berries in a small bowl and gently crush them using a spoon or your fingers. Once crushed, add a small amount of water to the bowl and stir. The seeds are relatively hard and should sink to the bottom, while the berry pulp will float. Carefully pour off the pulp and water, repeating this process if necessary until you have clean seeds.

4. Drying the Seeds

After separating the seeds, spread them out on a paper towel or a fine mesh screen in a cool, dry location with good air circulation. Allow the seeds to dry completely, which usually takes about one to two weeks. Proper drying is crucial to prevent mold growth during storage. Make sure to keep the seeds out of direct sunlight while they dry, as excessive heat can reduce seed viability.

5. Storing the Seeds

Once the seeds are fully dry, store them in an airtight container, such as a glass jar or a paper envelope. Label the container with the date and the type of plant to keep track of your seeds. Store the container in a cool, dark, and dry place, such as a pantry or a dedicated seed box. When stored properly, heirloom Malabar spinach seeds can remain viable for up to 3 years, though their germination rate may gradually decline over time.

6. Testing Seed Viability

If you’re using seeds saved from a previous season, you may want to test their viability before planting to ensure a successful crop. To do this, place a few seeds on a damp paper towel, fold it over, and put it in a sealed plastic bag in a warm location. Check after about a week to see if any seeds have germinated. If most of them sprout, you can proceed with planting as usual; if not, it may be time to save new seeds or purchase fresh ones.

By following these steps, you can develop a personal supply of heirloom Malabar spinach seeds, helping you maintain a continuous, self-sustaining crop each season. Plus, saving seeds not only allows you to enjoy this unique and hardy plant in your garden year after year, but it also helps preserve its genetic diversity and adaptability, making it a valuable addition to any sustainable garden.
