Rooibos tea plants are pretty specific when it comes to their growing conditions, they thrive in well-draining acidic soil with a pH between 6.0 and 7.0, which is typical of their native South African habitat. The climate should be mild with low humidity, and full sun to partial shade, temperatures between 15 and 30 degrees Celsius are ideal. As for watering, they're relatively drought-tolerant, but consistent moisture, especially during the first year, is crucial, so water them deeply once or twice a week, depending on weather conditions. I've found that overwatering can be detrimental, so it's better to err on the side of caution and monitor the soil moisture closely.
