Initial guidance described how to keep fresh basil viable by storing stems in water at room temperature and protecting leaves from excess moisture, while also outlining how to freeze pesto in airtight containers for up to three months. A later update expanded the advice to include a detailed blanching and pre‑freezing process that can preserve basil leaves for up to six months, allowing them to be added directly to hot dishes. It also warned against cutting basil at ground level, which destroys dormant axillary buds and prevents regrowth, and recommended trimming just above the second leaf pair to maintain healthy plants.
