Euphorbia tirucalli living fences: repelling wild boars on dry-zone farm plots?
5 Answers from travellers
Living fences in the southern dry zone must withstand intense drought while repelling roaming wild boar and cattle. Planting a double boundary hedge combining Euphorbia tirucalli (Pencil Cactus / Daluk) with thorny Acacia eburnea or Commiphora berryi establishes an effective barrier. Daluk produces an irritating, toxic white latex that deter foraging herbivores without needing wire fencing. Interplant with deep-rooted Agave sisalana along the outer perimeter to bind loose topsoil while retaining subsoil moisture across your farm boundary.
Avoid planting invasive Prosopis juliflora as a boundary hedge; its aggressive taproots deplete nearby shallow groundwater tables and choke adjacent crops.
Daluk sap causes temporary blindness if splashed into the eyes; workers must wear protective goggles and gloves when pruning mature boundary hedges.
Incorporating indigenous lime trees (Citrus aurantifolia) inside the inner perimeter provides valuable fruit crops alongside natural thorny security.
Composted prunings from non-toxic hedge components like Gliricidia sepium provide continuous green manure for your inner raised garden beds.
