Colleen's
Growing plants at altitude in Pretoria involves understanding what the highveld actually demands. Summer heat and hail, winter frost, and the specific pH of Gauteng clay soil mean generic gardening advice doesn't always land. Colleen's operates from the ground up — they propagate and cultivate stock suited to local conditions rather than importing everything. Their nursery shows how plants perform in real Pretoria summers, and their team knows which varieties handle the wind patterns around here, which ones resist the common pests, and how to prepare soil for what you're planting. That hands-on, location-specific knowledge shapes what they sell and the advice they give.
