Malabar spinach is a heat-loving climbing vine that US gardeners grow as a summer stand-in for true spinach, which bolts and turns bitter in July heat. Instead of quitting when temperatures climb into the 90s, this vine keeps pushing out thick, glossy, almost succulent leaves that taste mild and slightly earthy. The popular red-stemmed type is especially striking, twining up a trellis on bright magenta stems that look ornamental enough for a front-yard fence.

When and how to plant

Grow Malabar spinach as a warm-season crop, since even a light frost will kill it. Wait until all danger of frost has passed and the soil has warmed to at least 65 to 70 degrees F before setting out transplants or direct sowing, or start seeds indoors about six weeks earlier to get a head start. Give it full sun in most regions, though a little afternoon shade is welcome in the Deep South, and plant in rich, moist, well-draining soil with plenty of compost worked in.

Care

Keep the soil consistently moist, because dry spells make the leaves smaller and can trigger flowering, which turns the flavor stronger. Feed with a balanced or nitrogen-leaning fertilizer, or side-dress with compost, to fuel the steady leaf growth you want. This is a true vine that can climb 6 to 10 feet, so provide a sturdy trellis, fence, or teepee and space plants about 12 inches apart so air moves freely between them.

Common problems

Malabar spinach is fairly trouble-free, but watch for aphids and leaf miners on tender growth, and cucumber beetles or slugs chewing holes in the leaves. In warm, wet regions fungal leaf spots and root-knot nematodes can show up, so rotate planting sites and avoid overhead watering late in the day. Good spacing, airflow on a trellis, and a quick blast of water or insecticidal soap for aphids handle most issues before they spread.

Harvest

Start picking once the vine is established and putting out plenty of new growth, usually within a couple of months of planting. Pinch or snip off the young leaves and the tender stem tips a few inches long, taking a little from each plant so it keeps branching. Harvest often, since frequent cut-and-come-again picking keeps the vine productive and the leaves at their most tender right up until frost.

Growing Malabar Spinach in containers

Malabar spinach is well suited to containers, particularly where summers are hot. Plant one or two plants in a 5-gallon pot at least 12 inches deep, or use a larger trough with a sturdy trellis. Use fertile, well-drained potting mix, water when the upper inch of mix dries, and feed every 3 to 4 weeks with a balanced liquid fertilizer. Red-stemmed and green-stemmed types both grow well in pots.

Watering & feeding Malabar Spinach

Aim for roughly 1 to 1.5 inches of water per week, with more during hot, windy weather or when grown in containers. It is an average-water plant that becomes more thirsty during vigorous summer growth. Water deeply at the base in the morning and use mulch to keep the root zone cool and evenly moist. Container plants dry quickly and may need frequent checks, while limp leaves and dry soil suggest thirst and yellowing with constantly wet soil can indicate overwatering.

Malabar spinach is a moderate feeder grown for foliage, so it benefits from compost-rich soil and a modest supply of nitrogen. Prepare the bed with finished compost and avoid overly rich feeding that creates weak, overly lush vines. Add compost before planting and feed lightly after the plants are established, especially after repeated harvests. If growth slows in midsummer, use a small side-dressing of compost or a balanced fertilizer, but do not overapply nitrogen. Harvest often to encourage branching and use the removed foliage as a cue to provide light feeding if needed. Give vines sturdy support so watering and air circulation are easier to manage.

Saving Malabar Spinach seeds

Save seed from open-pollinated Malabar spinach, because F1 hybrids do not come true from seed. Wait for the dark purple-black berries to become fully ripe, pick them, mash them in water, and rinse away the pulp to recover the seeds. Dry the clean seed thoroughly on a screen or plate for at least one to two weeks before storing it cool and dry. Properly dried seed commonly keeps for about 3 to 4 years.

Malabar Spinach companion plants

Grow Malabar spinach on a trellis with low, heat-loving crops such as bush beans, peppers, or basil nearby, leaving its root zone uncrowded. Bush beans use different vertical space and, as legumes, can contribute nitrogen to the bed after their residues decompose. Add flowering plants such as borage or sweet alyssum nearby to support pollinators and beneficial insects, rather than relying on a specific pest-repellent claim. Avoid placing it with large vining cucurbits or another vigorous climber, because they compete for trellis space, sun, and water.
