Plant herbs when the temperatures are in the 70s. Most herbs can't take frost. Herbs grow best in an open, friable soil. If the plants struggle, they become bitter. Herbs do best when sown directly into the soil rather than as transplants.
Herbs grow best with at least six hours of sunlight a day.
Herbs must be thinned. Pinch back the plants as they grow to keep them bushy. Feed monthly if using granular fertilizer. Aphids are the main pest problem when growing herbs. I wash them off with water.
