When to Plant in the Garden
After gardening and farming for more than 20 years in Wexford County, Theresa Williams has gained experience as to what to plant when. Here are the seed starting dates and outdoor planting dates she recommends for the most popular crops in our area. Be forewarned that these are averages – Wexford County in the last 10 years has experienced frost as late as July 2, and as early as August 18! If you can add one layer of protection, such as floating row cover or a cut-off milk jug, these dates can be moved back two weeks.
Those crops with ** after them can be sown at weekly or bi-weekly intervals for continued harvests.
