Ignoring Soil pH Requirements
Thyme hails from the alkaline soils of the Mediterranean, while sweet basil—native to tropical Asia—prefers neutral to slightly acidic ground. Skip a pH test, and you risk leggy thyme or yellowing basil. I once had vibrant basil leaves turn droopy because my bed was too basic from leftover lime!
Aim for a pH around 6.0–7.0. If your soil skews too acidic, add lime; if too alkaline, incorporate sulfur or peat moss. Balanced pH means stronger roots, better nutrient uptake, and aromatic, flavor-packed leaves.
