by

Creating a sowing calendar tailored to Zone 3 is essential for gardeners aiming for a successful harvest in April. Zone 3, characterized by its cold climate and short growing season, requires careful planning and timing to ensure plants thrive. This guide provides a detailed schedule for sowing various vegetables and herbs during April in Zone 3.

Understanding Zone 3 and Its Climate

Zone 3 is defined by its cold winters and a relatively short growing season, typically from late May to early September. Spring arrives late, and soil temperatures remain low for extended periods. Gardeners must start seeds indoors or use cold frames to extend the growing season and protect tender plants.

General Sowing Tips for April in Zone 3

  • Start indoors: Many warm-season crops benefit from early indoor sowing.
  • Use cold frames or row covers: Protect seedlings from late frosts.
  • Monitor soil temperatures: Aim for at least 10°C (50°F) before transplanting warm-season crops.
  • Plan for succession planting: Extend harvests by sowing in intervals.
