Entretien

Keep this plant in a spot with intense, direct sunlight to mimic its natural desert home. Watch for yellowing leaves or leaf drop, which often signal that the soil is staying too wet for too long. It is very sensitive to overwatering, so always let the soil dry out completely between drinks.

Arrosage
Allow the soil to dry out entirely between waterings to prevent root rot.
Engrais
Apply a balanced, slow release fertilizer sparingly during the active growing season.
Taille
Prune lightly in late winter to maintain shape and remove any dead or crossing branches.
Rempotage
Repot only when the roots have clearly filled the container, as this plant prefers to be slightly root bound.
Sol
Sandy or rocky well draining soil

6.0 to 8.5

Signes qu'il faut rempoter

  • Roots growing out of the drainage holes.
  • Water sitting on the surface for too long.
  • Stunted growth during the active season.

Sécurité

Humains
The plant is generally non-toxic, though the sharp thorns pose a significant physical injury risk.
Enfants
Keep children away from the branches because the hooked thorns are extremely sharp and can cause deep cuts.
Allergènes de contact
The sharp, hooked thorns can cause painful skin punctures and scratches.
Allergènes aéroportés
The pollen can trigger mild allergic reactions in sensitive individuals during the flowering season.
Comestibilité
The gum arabic harvested from the tree is edible, but raw seeds should be avoided as they may contain anti-nutrients.

La cultiver

Multiplication
seed, cuttings
Quand planter
Spring
Hivernage
Move the plant to a frost-free location if temperatures drop near freezing. Reduce watering significantly during the winter dormancy period.
En pot
It can be grown in large containers with excellent drainage, but it will eventually outgrow most indoor spaces.

Seed Scarification

  1. 1. Nick the hard seed coat with a file.
  2. 2. Soak seeds in warm water for 24 hours.
  3. 3. Plant in well-draining sandy soil.

Group this tree with other drought-tolerant species that do not require frequent irrigation to prevent root rot.

Bonnes associations

  • Rose du désert — They share similar requirements for high heat and low water.
  • Aloès — These succulents thrive in the same arid, sunny conditions.

Espèces similaires

  • Vachellia nilotica — Shares a similar growth habit and thorny appearance.

Ce qu'on demande souvent

Does it need much water?
No, it is highly drought tolerant and prefers to dry out between waterings.
Can I grow it indoors?
It is difficult to keep indoors due to its size and need for intense, direct sunlight.

D'où vient le nom

The name Senegalia refers to its prevalence in the Senegal region, while the specific epithet senegal confirms this origin.

Bon à savoir

  • The gum is harvested by making small incisions in the bark.
  • It is incredibly drought tolerant and thrives in arid desert conditions.
  • The wood is very hard and durable, often used for tool handles.
  • It fixes nitrogen in the soil, helping nearby plants grow better.
