Establishing an avocado orchard is a costly, long-term investment. To achieve a successful return on investment, various factors need to be considered when planning a new avocado development, including climatic conditions of the site, soil and water requirements, and selecting cultivars best suited for these conditions. Keep these four important considerations in mind when making your decisions:
Location
- Choose a site with warm, humid conditions or a cool mist-belt area suited to avocados.
- Early areas (Levubu, Tzaneen, etc.): Early to mid-maturing cultivars, protect young trees from heat.
- Late areas (KwaZulu-Natal, Western Cape, etc.): Mid to late-maturing cultivars, watch for frost.
Timing
- Warmer areas: Plant in August, September, October, March or early April.
- Cooler areas: Plant between September and December.
- Do not plant in the middle of the day or above 33 °C.
Cultivar selection
- Match cultivar to climate and market demand.
- Be aware of South American supply peaks between May and August.
- Choose cultivars ripening September to April for less competition.
Soil preparation
- Use well-drained soils with at least 2 m depth in high rainfall areas or 1.6 m in moderate areas.
- Ridge the orchard to improve drainage.
- Build organic matter near the surface for feeder roots.
- Avoid saline soils and pH below 5 or above 7.8.
- Choose rootstock that performs well in your soil type.
Key takeaway
Plan before you plant. The right location, timing, cultivar and soil prep will give your orchard a strong start, healthier trees and better long-term yields.
