Poi (Red) / Malabar Spinach (Red)

Light Conditions:

Red Poi grows well in partial shade to full sun with morning or dappled sun, especially in hot Caribbean afternoons.

• Full Sun:
  Red Poi could be grown in a location that receives at least 6 hours of sunlight per day.
• Partial Shade:
  In our climate, Red Poi grows best with 3 to 6 hours of sunlight per day, primarily morning sun, with slight shade.
• Avoid intense midday sun on young plants to prevent leaf scorch.

Temperature and Humidity:

• Warm Temperatures:
  Red Poi prefers warm tropical conditions of between 21°C to 32°C.
• High Humidity:
  It enjoys high humidity, mimicking its native tropical environment.

Soil:

• Plant Red Poi in rich, fertile, well-draining soil with plenty of organic matter.
• Ensure that the soil has a slightly acidic to neutral pH of between 6.00 to 7.00.
• The plant has been reported to grow in moist tropics from sea-level to 1,500 metres in commercial agricultural settings.
• Mulch (such as grass clippings and wood chips) can be added to the surface of the soil to retain moisture and keep down weeds.

Watering Frequency:

• Keep consistently moist but not waterlogged.
• Water deeply 2 to 3 times weekly during dry spells; reduce if heavy rain.
• It can tolerate frequent rainfall.
• Do not allow the soil to dry out for an extended period as this will stress the plant.

Amendments and Fertiliser:

• Compost:
  Pre-plant compost or aged manure is excellent. Red Malabar Spinach is regarded as fast growing and should be topped off with organic matter ever so often if growing directly in the ground.
• Balanced Fertiliser:
  Monthly feeding with a balanced (10-10-10 NPK) or veggie-tone fertiliser during the growing season.

Pruning and Maintenance:

• Trim Red Poi stems regularly to encourage bushier growth and prevent the vine from overrunning.
• Pinch tips regularly once 4 to 6 leaves appear to promote branching.
• Remove any yellowing leaves to keep plants healthy.

Pest and Disease Control:

• Pests:
  Watch for leaf miners, aphids, whiteflies, slugs and snails. Treat early with insecticidal soap or neem oil.
• Diseases:
  Good air circulation prevents fungal issues; avoid overhead watering at night.

Harvesting Methods:

• Harvest young leaves and tender stems as needed—preferably early morning.
• Cut 2 to 3 inches from the top, allowing full regrowth in about 3 weeks.
• Regular harvest promotes fresh, vigorous growth.

Propagation:

Propagating Red Poi in the Caribbean is easy and rewarding. Start propagation during the rainy or early wet season for natural moisture and warmth. Space transplants 12 to 18 inches apart for good airflow and growth. Propagated plants grow quickly and will be ready for harvest in about 4 to 6 weeks. Here are the best methods for ensuring successful growth:

• By Seeds:
  While stem cuttings are faster, you can also propagate from seeds. Harvest seeds from mature, dark purple berries. Soak seeds overnight in water to improve germination. Sow about ½ inch deep in warm, moist soil. Germination takes 7 to 14 days, depending on temperature. Seedlings can be transplanted when they are 3 to 4 inches tall.
• By Cuttings:
  Pruning can aid in stimulating new growth and make the plant bushier. This is the most reliable and quickest method in the warm, humid Caribbean climate. Select a healthy vine about 6 to 8 inches long with at least 2 to 3 leaf nodes. Snip just below a node, remove the lower leaves. If rooting in water, place the cutting in a clear jar of water and change the water every few days—roots usually appear within 7 to 10 days. If rooting in soil, insert the cutting directly into moist, well-draining potting mix—keep in partial shade and maintain consistent moisture. Once established, transplant into a larger container or garden bed.

Red Malabar Spinach is regarded as safe to eat and poses no significant toxicity, making it a lovely addition to both gardens and kitchens. Here's what you need to know:

• Non-Toxic Edible Green:
  All parts—leaves, stems and tender shoots—are widely used in both cooking and traditional herbal remedies without known harmful effects.
• Low Allergy Risk:
  Unlike some greens, there are no common reports of allergic reactions, though individuals with general leafy green sensitivities should exercise normal caution.
• Oxalates:
  Like many leafy greens, Red Poi may contain natural oxalates, which can contribute to kidney stones in very sensitive individuals. Those prone to kidney issues may want to consume it in moderation, ideally with a doctor’s guidance.

 

Garden Environment Caution:

Because it’s often trellised or left to spread, there’s a small chance it could shade smaller companion plants—so proper placement and pruning are wise.

 

Bitter Taste When Flowering:

Leaves tend to taste bitter when going to flower.
