How to Grow Malabar Spinach in Florida Heat
Regular spinach bolts the minute it feels a Florida summer. Malabar spinach goes the other direction. It thrives when the heat cranks up, climbs a trellis, and produces leaves all the way into fall.
If you have been fighting to grow greens in summer, here is what you need to know to get this climbing heat spinach in the ground and growing fast.
What You Need to Get Started
- Malabar spinach seeds or a small cutting from a friend's plant
- A trellis, fence, or cage (it will climb to 6 feet and beyond)
- A sunny spot, at least 6 hours of direct sun
- Compost to mix into the planting hole
- Consistent watering during the first two weeks
Red-stemmed and green-stemmed varieties both grow well in Florida. The red variety is showier. Either one eats the same.
When to Plant Malabar Spinach in Florida
Malabar spinach wants warmth. Plant it after your last frost risk, which in Central and South Florida means March or earlier. North Florida gardeners, wait until April to be safe.
It keeps producing through summer and into early fall. It will die back when temperatures drop below 50 degrees, so the natural end of season in North Florida is November. In zone 10, it can go much longer.
How to Plant It
If starting from seed, soak seeds in water for 24 hours before planting. This softens the hard seed coat and speeds germination. Plant seeds about half an inch deep and water well.
Germination takes 10 to 21 days. Be patient. Once it sprouts, growth picks up fast. From cutting, it roots quickly in moist soil and needs almost no fuss.
Malabar Spinach Care: The Basics
Watering
Keep the soil consistently moist during the first two weeks. After it is established, Malabar spinach handles short dry spells well, but it will produce more and taste better with regular watering in summer heat.
Fertilizing
A light application of balanced fertilizer once a month keeps production up. Too much nitrogen produces oversized leaves with a slimy texture, so do not overdo it. Compost at planting is usually enough for the first 60 days.
Training the Vine
Malabar spinach is a fast climber. Guide the main stem to your trellis early before it starts wrapping around itself on the ground. Once it is climbing, it takes care of the rest.
How to Harvest Malabar Spinach
Start harvesting young leaves and shoot tips once the plant is about 12 inches tall. Harvest often to keep new growth coming. If you let it flower and set seed, leaf production slows down.
The leaves and stems have a slight mucilaginous texture when cooked, similar to okra. Use them in soups, stir fries, or lightly sauteed with garlic. Raw in salads works fine when the leaves are young and small.

Common Problems and Quick Fixes
Leaves turning pale yellow: Usually a nitrogen deficiency. Add a light balanced fertilizer.
Plant not climbing: Just needs guidance. Tie the main stem to your trellis with a loose twist tie or garden twine.
Slow growth: Check the sun. Malabar spinach needs at least 6 hours of direct sun to perform well.
