What is Red Acacia?
Red Acacia (Vachellia seyal) is a hard-care plant from the Fabaceae family. Vachellia seyal, commonly known as Red Acacia or Shittim Wood, is a fast-growing, thorny evergreen tree native to the arid Sahel region of Africa and the Middle East. It produces distinctive bright yellow, globose flower heads with a sweet, spicy scent, and is renowned for its pale reddish or greeni...
Red Acacia grows up to 17.0m, with spread of 1200cm, watering every 14 days, 10°C – 45°C, 20–50% humidity. It is not suitable for indoor environments and safe for pets.
Care Guide
How to Water
Water deeply but infrequently — every 10–14 days during dry spells, less often once fully established. This tree is extremely drought-tolerant and suffers more from overwatering than underwatering. Ensure soil drains freely to avoid root issues.
Lighting
Red Acacia demands full, direct sunlight for at least 6–8 hours a day. It cannot tolerate shade and will decline if light is insufficient. Ideal for open landscapes, savannahs, and dry gardens.
Ideal Soil
Plant in sandy loam, clay loam, or gravelly soil with pH 6.0–8.0. Avoid waterlogged or consistently wet conditions. This tree tolerates poor, saline, and stony soils — rich soil is not required and may encourage excessive foliage at the expense of flowering.
Recommended Pot
Not suitable for containers — best grown in open ground in large landscapes or agroforestry settings.
About Red Acacia
Vachellia seyal, commonly known as Red Acacia or Shittim Wood, is a fast-growing, thorny evergreen tree native to the arid Sahel region of Africa and the Middle East. It produces distinctive bright yellow, globose flower heads with a sweet, spicy scent, and is renowned for its pale reddish or greenish bark. Historically significant as the biblical "shittim wood" used to construct the Ark of the Covenant, this resilient tree thrives in full sun, tolerates drought and periodic flooding, and plays a vital role in dryland ecosystems through nitrogen fixation.
How to Propagate
Seed Propagation
Scarification and pre-soaking are essential — untreated seeds have very low germination rates. Use fresh seeds for best results.
- 1 Scarify seeds by nicking the seed coat or rubbing with sandpaper
- 2 Soak scarified seeds in warm water for 24 hours
- 3 Sow seeds in sandy or loamy soil at 21°C (70°F)
- 4 Keep soil lightly moist until germination occurs (2–4 weeks)
- 5 Transplant seedlings to full sun once they reach 15 cm

Common Problems
Rust
Rust is a common fungal disease caused by fungi in the order Pucciniales that affects a wide variety of plants. The disease gets its name from the characteristic orange, yellow, or reddish-brown pustules that appear on leaves, resembling metal rust. This obligate fungal parasite requires living plants to survive and can cause significant economic losses in agricultural crops.
Powdery Mildew
Powdery mildew is a common fungal disease caused by various fungi species including Erysiphe, Podosphaera, Oïdium, and Leveillula. It affects over 10,000 plant species worldwide. The disease thrives in warm, dry climates with high humidity and appears as a distinctive white powdery coating on plant surfaces.
Leaf Spot
Leaf spot is a common fungal disease caused by various pathogens including Alternaria, Ascochyta, Colletotrichum, Septoria, and Venturia. It primarily affects leaves, causing discolored spots that can lead to premature leaf drop if left untreated.
Aphids
Aphids are small, soft-bodied, pear-shaped insects (1/16 to 1/8 inch long) that feed by sucking nutrient-rich sap from plants. They reproduce rapidly and can quickly weaken plants, causing distorted growth and transmitting plant viruses. Aphids come in various colors including green, black, red, yellow, brown, and gray. They secrete honeydew, a sticky substance that attracts ants and encourages sooty mold growth.
