Growing plants for sale in Gauteng's highveld means dealing with winter frost, summer hail, and water restrictions that keep tightening. Nurseries here use shade cloth strategically to protect tender seedlings during October and November heat spikes, and they harden off stock gradually so plants survive the shock of a garden environment. The potting mix, compost quality, and fertiliser programmes determine whether a young plant develops strong roots or struggles. Many nurseries maintain their own propagation facilities—cuttings in mist benches, seed germination trays, tissue culture for orchids—rather than relying entirely on imports. Pest and disease management indoors is meticulous because one outbreak spreads quickly through a greenhouse. The infrastructure and knowledge required to do this well separates casual plant sellers from serious growers.
