Overview
So true spinach keeps quitting on you the second it gets hot? That's exactly when Malabar spinach steps up. Don't let the name fool you, because it isn't related to true spinach at all. It's really a twining vine in the family Basellaceae, a tropical plant that's perfectly happy in the sticky summer weather that sends other greens straight to seed.
It's a fast climber, too, easily hitting 6 to 10 feet (1.8 to 3 m) on a trellis in one warm season. The leaves are thick and glossy with a mild, slightly citrusy taste, and they're great raw in a salad or cooked down like spinach, where they add a little thickening to soups and stir-fries.
Here's the nice part: once it's climbing, it barely asks for anything. Just give it sun, steady moisture, and something to grab onto, then pinch the tips now and then for more leaves. The one ongoing job? Snapping off flower spikes, because as soon as the vine sets seed the leaves get smaller and tougher.
Care
The short version: full sun and real warmth, plus a sturdy trellis to climb. Keep the soil evenly moist, feed it through the season for leafy growth, and pinch the tips so it doesn't rush into flower.
Light
It wants full sun for the biggest, fastest growth, though it'll take a bit of afternoon shade in a really hot garden. More sun just means more leaves, faster, and honestly that's the whole reason to grow it.
Water
Keep the soil evenly moist, roughly every 2 to 4 days and more when it's hot out. Let it dry out and the vine rushes into flower, which shrinks and toughens the very leaves you're after, so a steady drink is the trick.
Soil
Plant it in rich, well-drained loam with plenty of organic matter. A pH of 6.0 to 6.8, just a touch acidic, is right in its wheelhouse and keeps the leaves nice and tender.
Temperature
Heat is basically the whole game here. It grows best between 59°F and 95°F (15°C to 35°C) and just sulks when it's cold, so there's no point rushing it out before the soil warms.
Humidity
Funny thing, most greens hate humidity but this one loves it, doing best at 60% to 90% relative humidity. That tropical thirst for damp air is exactly why it thrives in muggy summers that flatten true spinach.
Feeding
Feed it monthly through the growing season with a balanced, nitrogen-forward fertilizer. That extra nitrogen pushes the leafy growth that makes the vine worth its space.
Pruning
Pinch the growing tips often to get bushy branching and keep tender leaves coming. And just as important, snap off flower spikes the second they show up, since flowering turns the leaves small and tough.
Repotting
Since it's grown as an annual, it hardly ever needs repotting, but a container plant should get potted up once its roots fill the pot. Keep an eye out for roots circling the container, quick wilting between waterings, and new growth that's stalled.
Size & spacing
On a trellis it climbs 6 to 10 feet (1.8 to 3 m) tall and spreads 12 to 35 inches (30 to 90 cm) wide. Give it strong vertical support and enough room for air to move through the leaves.
When to plant
This one's all about heat, and it won't do a thing until the soil warms up. Start seed indoors in late winter, but wait to move plants outside until the frost is gone and the ground's warmed, then you can pick leaves right through the warm season.
Northern hemisphere
Southern hemisphere
Typical months for a temperate climate: start earlier in warm zones, later where spring frosts linger.
- Sow: 6-8 weeks before the last expected spring frost
- Plant: after all danger of frost has passed and soil is warm (above ~18°C / 65°F), trained onto a trellis or other vertical support
- Harvest: harvest leaves continually once vines are established through the warm season
Hardiness
USDA hardiness zones: 7–12
Temperature: down to -18°C
Troubleshooting
Most trouble with this vine turns up on the leaves or as a slowdown in fresh growth. Catch it early and you can keep those tender leaves coming for months. Just find what matches what you're seeing below, then act while it still helps.
Stunted, wilting plants with knotty galls on the roots
Knobby lumps on the roots usually mean root-knot nematodes, tiny soil pests that block the plant from drinking and feeding. A badly hit plant can't really be saved, so pull it and toss it, then move the bed to a crop the nematodes can't feed on. Building up organic matter helps the soil push back over time, too.
Fix:
- Remove and destroy heavily infested plants
- Rotate to non-host crops
- Amend soil with organic matter to support beneficial organisms
Flower spikes appear and the leaves turn small and tough
Once the vine throws up spikes of little flowers and dark berries, it's switched over to seed production, and the leaves start shrinking and toughening. Shorter days, heat, and dry spells all nudge it that way. So pinch those flower spikes off the moment you spot them, keep the soil evenly moist, and harvest the tips often to coax it back into leaf.
Fix:
- Pinch out flower spikes promptly
- Keep soil evenly moist
- Harvest tips frequently
Small brown spots with dark edges on the leaves
Those spots are Cercospora leaf spot, a fungus that shows up in warm, wet, humid weather. Pick off the marked leaves, spread the trellis a little wider so air can move, and water down at the soil so the foliage stays dry, and you'll get ahead of it.
Fix:
- Remove and dispose of affected leaves
- Improve air circulation and trellis spacing
- Water at the soil line to keep foliage dry
Vines sprawling and tangling along the ground
Malabar spinach is a twining climber, so it's looking for something to grab. With nothing to grip, the stems just run flat and knot up. Set a sturdy trellis, fence, or stake at planting and guide the young shoots onto it, since this vine can climb past 6 to 10 feet (1.8 to 3 m).
Fix:
- Install a sturdy trellis, fence, or stake
- Gently train young shoots onto the support
Toxicity
Good news for the whole household: this is a vegetable, not a poison. It's safe around cats, dogs, livestock, and kids, and the leaves are meant for the dinner table. The only thing worth knowing? The leaves are high in oxalates, same as true spinach, which matters if you're prone to kidney stones.
Safe for
People · Cats · Dogs · Horses · Rabbits · Livestock · Birds
Cats None
Nothing to stress about with cats. If one nibbles a leaf, the worst you'd see is a mild, brief tummy upset, just like with any new green.
Dogs None
Totally fine around dogs. There's no toxin in the leaves or stems, so a nosy dog can chew on the vine without any harm.
Horses Safe
No worries for horses either. It's a leafy vegetable, not a poisonous plant, so grazing on it won't cause any trouble.
Rabbits Safe
Rabbits can eat the fresh leaves safely. Like with any leafy green, just ease it in slowly so it stays a small part of a balanced diet.
Livestock Safe
Cattle, goats, and sheep are all fine near it. There's nothing toxic in the foliage, and it's even grown as fodder sometimes.
Birds Safe
Pet and backyard birds can nibble the leaves without any concern. The plant just doesn't carry anything that'd harm them.
People Safe
It's a kitchen vegetable, eaten raw or cooked. The only catch is the leaves run high in oxalates, good to know if you're prone to kidney stones.
Leaves are high in oxalates (as with true spinach), a dietary consideration for people prone to kidney stones, not a pet-poisoning concern.
Varieties
There are really only a couple of forms you'll run into, and they mostly differ in stem color. Both grow the same way and taste pretty much alike, so you can't go wrong either way.
Basella alba (green)
This is the everyday green-stemmed one, easy to pick out by its green stems and thick, juicy green leaves.
Basella alba 'Rubra'
With red-to-purple stems and leaf veins, this one's pretty enough to grow as an ornamental as well as for greens.
How to propagate
Want more plants? That's easy, whether you're starting from seed or taking cuttings off a vine you've already got going.
SeedEasy
Start indoors 6-8 weeks before last frost or direct sow after soil warms · Germination in roughly 10-21 days; soaking or scarifying the hard seed coat speeds emergence
You can start seed indoors 6 to 8 weeks before your last frost, or just sow it right into warm soil once the cold's passed. The seed coat's hard, so soak it overnight first, and the seedlings usually pop up in roughly 10 to 21 days.
Stem cuttingsEasy
During the warm growing season · Roots form in about 1-3 weeks in warm, moist conditions
Taking cuttings during the warm growing season is the fastest way to more plants, hands down. Just stand a healthy stem in water or moist mix and it roots in about 1 to 3 weeks, giving you a fresh vine with basically no effort.
Myths
Malabar spinach is just a kind of true spinach.
Nope, they only share a name and a use. Malabar spinach is a twining vine in the family Basellaceae, with no relation to true spinach (Spinacia oleracea, in the Amaranthaceae), and it's a handy warm-season fill-in for when real spinach bolts in the heat.
Since it tastes like spinach, it must skip spinach's downsides.
Well, it actually keeps one of them. The leaves run high in oxalates, just like true spinach, so that's worth remembering if you're prone to kidney stones.
