🌼 Growing Tips for Beginners

  1. Choose the right site: Most easy seeds love full sun (6–8 hours per day).
  2. Prep the soil lightly: Remove weeds and loosen soil before direct sowing.
  3. Succession sowing: Plant every 2–3 weeks for continuous blooms.
  4. Don’t overwater: Many easy seeds thrive on less care than you think.
  5. Harvest often: Cutting zinnias, cosmos, and rudbeckia encourages more flowers.
