A regional guide for Gauteng, the Cape and KZN
The same basil seedling that romps away in a Pretoria bed can turn yellow and sulk within a month in Durban. Nothing was wrong with the plant. The climate zones across South Africa are not a marketing detail, they decide what survives a season and what quietly gives up by February.
Three gardens came up in this thread, and the differences are worth spelling out before anyone buys another tray of seedlings.
Gauteng gardens deal with sharp winter frost and heavy summer downpours that wash nutrients out of sandy beds fast. Soil prep matters more here than watering. Dig in compost in early spring, keep a layer of mulch through the rainy months, and plant frost-tender herbs in pots you can move against a north-facing wall when the first cold front arrives. Rosemary, sage and thyme handle the cold without fuss. Tomatoes need staking before the storms, not after.
The Cape runs on the opposite rhythm. Rain falls in winter, so the growing season is a dry one and watering becomes the main job from November onwards. Beds here benefit from a thick mulch and drip lines rather than overhead spray, which also cuts down on mildew. Lettuce, chard and most herbs do well in the shoulder seasons. Indigenous options like buchu and wild rosemary settle in without much attention once established.
Coastal KZN is humid, salty and warm, which suits tropical herbs but punishes anything that dislikes wet roots. Raised beds help. So does spacing plants wider than you would inland, because airflow is the difference between a healthy patch and a fungal problem. Curry leaf, lemongrass and chillies thrive. Basil does well if you keep it out of the worst of the salt wind.
Sometimes a plant that worked perfectly in one region simply will not settle in another. Before giving up, check three things: how much direct sun the new spot actually gets, whether the soil drains the way the old bed did, and how the local water differs. Adjust one variable at a time and give it a full season. If it still struggles, swap it for something the neighbours already grow well.
