As September progresses, monitor soil moisture carefully, especially given the historical average rainfall of 70.6mm. Begin to clear spent summer crops to prevent pest and disease buildup. Consider adding compost to beds in preparation for future plantings. Protect tender plants from potential early cold snaps, though average temperatures remain mild. Ensure good air circulation around plants to minimize fungal issues with increasing humidity.
