Note: Indoor Plant in moderate climates

Pachira glabra, commonly known as the Saba Nut or Malabar Chestnut, is a tropical plant valued for both its edible nuts and ornamental qualities.

Common Name: Saba Nut, Brazilian chestnut, Malabar Chestnut
Botanical Name: Pachira glabra

  • Cold Hardiness Zones: 10-12. It’s a tropical plant and does not tolerate frost.
  • Soil pH: Prefers slightly acidic to neutral soil (pH 6.0 to 7.5).
  • Watering Needs: Requires regular watering but is sensitive to over-watering. The soil should be well-drained.
  • Food Forest Layer: INDOOR in moderate/cold climates, canopy layer in zones 10-12.
  • Which Parts of the Plant are Eaten as Food: The seeds/nuts are edible and often roasted.
  • Blooming Season: Typically blooms in the spring and summer.
  • Harvest Season/Regularity: Nuts are usually harvested in the fall.
  • Fruiting Age: Begins to bear nuts at around 5-7 years of age.
  • Age of Maturity (Full Size and Peak Fruiting): Reaches full size in about 10-15 years.
  • Average Mature Yield: Can produce a substantial number of nuts once fully mature.
  • Pollination for Fruit: Usually self-pollinating.

Propagating Saba Nut


Propagating Pachira glabra, or the Saba Nut, can be successfully achieved through both seeds and cuttings.

Propagation from Seeds

  1. Seed Collection: Collect seeds from a mature Pachira glabra tree. The seeds are found inside the large, woody fruit pods.
  2. Seed Preparation: Clean the seeds by removing any fruit pulp. It’s important to use fresh seeds as their viability decreases with time.
  3. Germination Environment: Plant the seeds in a well-draining soil mix. They prefer a warm, humid environment, similar to their native tropical habitat. The ideal temperature for germination is around 25-30°C (77-86°F).
  4. Sowing Depth: Plant the seeds 1-2 inches deep in the soil.
  5. Watering: Keep the soil consistently moist but not waterlogged. Over-watering can lead to rot.
  6. Germination Time: Seeds typically germinate within a few weeks to a couple of months.
  7. Care Post-Germination: Once the seedlings emerge, ensure they receive adequate light and moisture. Gradually acclimate them to outdoor conditions if they are to be planted outside in a suitable climate.

Propagation from Cuttings

  1. Cutting Selection: Choose a healthy, disease-free branch. A cutting with several leaf nodes is ideal.
  2. Cutting Preparation: Cut a 6-12 inch section of the branch. Make the cut just below a leaf node. Remove the lower leaves, leaving a few at the top.
  3. Rooting Hormone (Optional): Though not always necessary, applying rooting hormone to the cut end can enhance rooting success.
  4. Planting the Cutting: Plant the cutting in a pot with well-draining soil. Ensure at least one node (where you removed leaves) is beneath the soil surface, as roots will develop from these nodes.
  5. Environment: Maintain a humid environment, as cuttings need high humidity to root successfully. Covering the pot with a plastic bag can help retain moisture, but ensure there’s some air circulation to prevent mold growth.
  6. Watering: Keep the soil moist but not soggy. Check regularly to maintain proper moisture levels.
  7. Root Development: Roots typically begin to form within a few weeks. Once the cutting has established a strong root system, it can be transplanted to a larger pot or directly into the ground, depending on the climate.

General Tips

  • Light: Whether from seed or cutting, young Pachira glabra plants prefer bright, indirect light.
  • Soil: Use a well-draining, fertile soil mix.
  • Temperature: Protect the plant from temperatures below 10°C (50°F), as they are sensitive to cold.
  • Patience: Propagation, especially from seeds, can be a slow process. Patience is key.

Brazilian Chestnut Roasted on an Open Fire

  1. Prepare the Nuts:
  • First, rinse the nuts to clean any dirt off the shells.
  • Then, make a small incision or X-shaped cut on the flat side of each nut. This is important to prevent them from exploding due to steam buildup inside the shell when heated.
  1. Roasting Over an Open Fire:
  • Use a long-handled cast iron pan or a chestnut roasting pan if you have one. These pans usually have holes in them to allow the flames to come in direct contact with the nuts.
  • Place the nuts in the pan in a single layer, so they heat evenly.
  • Hold the pan over the open fire. Keep the nuts moving by shaking the pan frequently. This prevents them from burning and ensures even roasting.
  • The roasting typically takes about 15 to 20 minutes, depending on the intensity of the fire. The shells should blacken and open up where you made the cuts, and you can smell the rich, nutty aroma.
  1. Cooling and Peeling:
  • Once roasted, remove the nuts from the fire and let them cool just enough to handle.
  • Peel off the shells. The nuts should be tender and golden brown.
  1. Enjoy:
  • Enjoy them warm as they are, or use them in other recipes.
