Planting Prognostication: Understanding last frost and planting dates.  “Except for areas of the US that are more tropical like southern Florida or Hawaii, most gardener’s planting schedules are set around winter weather and the possibility of frost or freeze.  And even for gardeners in those more tropical areas, planting sometimes needs to be planned to schedule around the extreme heat of summer.  Understanding these planting times can really lead to success or failure, especially for vegetable gardens, tender annuals, tropicals, and non-dormant perennials.” (John Porter, Gardenprofessors.com) https://bit.ly/3a3wvVV
