Olea Africana – Growing the African Wild Olive Tree

outdoor plant

 

Olea africana, commonly known as the African wild olive tree, is one of Kenya’s most important indigenous trees. With its tough, evergreen leaves, deep roots, and hardy nature, it thrives in dry conditions and is ideal for live fencing, soil conservation, and reforestation projects across the country. It’s both functional and culturally significant, making it a must-have for eco-conscious farmers and landscapers in Kenya.

 

Benefits of Growing Olea Africana

  • Drought Resistant: Thrives in dry, arid, and semi-arid climates across Kenya.
  • Indigenous & Long-Lived: Naturally suited to Kenyan soils and can live over 100 years.
  • Medicinal Uses: Leaves and bark are used in traditional herbal medicine.
  • Excellent for Fencing: Grows strong and thick, ideal for live fences and windbreaks.
  • Hardwood Timber: Dense wood used in carving, tools, and furniture.

How to Grow Olea Africana in Kenya

1. Ideal Climate and Location

Olea africana grows best in areas with full sunlight and well-draining soils. It thrives in dryland counties like Machakos, Kitui, Baringo, and even highlands like Nyeri and Kericho. It is highly adaptable to Kenya’s diverse climates.

2. Soil Requirements

Grows in a variety of soils, including sandy, loamy, or rocky soils. Ensure the soil is well-drained to prevent root rot. Add compost or manure during planting for better root establishment.

3. Watering Schedule

  • Young seedlings should be watered 2–3 times per week until established (about 2–3 months).
  • Mature trees need little to no watering except during extreme drought.

4. Feeding and Fertilizer

Not a heavy feeder. Apply compost or organic fertilizer during the rainy season for faster growth. Avoid over-fertilizing, especially with high-nitrogen products.

5. Pruning Tips

Prune in the dry season to remove dead wood or to shape the tree for fencing or aesthetic purposes. Minimal pruning is needed once mature.

Common Problems and Solutions

  • Slow Growth: Natural for this species. Speed up growth by using well-composted soil and watering regularly when young.
  • Whiteflies or Aphids: Rare, but can be managed with neem oil spray.
  • Leaf Drop: Caused by sudden temperature changes or transplant shock. Water gently and avoid moving the plant after establishment.

Uses of Olea Africana

  • Timber: Ideal for making durable furniture, carvings, and handles.
  • Medicinal: Leaves used in teas or decoctions for treating colds, fever, and inflammation.
  • Soil Stabilization: Great for controlling erosion on slopes and riverbanks.
  • Cultural: Used in traditional rituals and often planted near homesteads for protection.

Final Thoughts

The African wild olive tree is one of the most valuable indigenous trees in Kenya. Whether you are planting for environmental reasons, fencing, or cultural significance, Olea africana is a strong, beautiful, and lasting investment in your land.
