by

October is a crucial month for Zone 7 gardeners looking to extend their growing season and enjoy vibrant blooms well into the fall and early winter. Sow these top annuals now to ensure a colorful garden that lasts through the cooler months.

Why Sow Annuals in October?

Sowing annuals in October allows plants to establish strong roots before the coldest weather sets in. Many of these plants will either bloom in late fall or survive the winter to bloom again in spring, providing continuous color and interest.

Top Annuals to Sow in October for Zone 7

  • Calendula (Pot Marigold) – Known for its bright orange and yellow flowers, calendula thrives in cooler weather and can bloom from late fall to early winter.
  • Sweet Alyssum – This fragrant, low-growing annual produces clusters of tiny white or purple flowers and can tolerate the cooler temperatures of October planting.
  • Violas and Pansies – These hardy flowers are perfect for October sowing, offering vibrant colors that can brighten up any garden bed or container.
  • Calendula – With its cheerful blooms and ease of growth, calendula is an excellent choice for fall planting.
  • Stock (Matthiola) – Known for its sweet fragrance, stock can be sown now for late fall blooms and even early spring flowers.
  • Ornamental Kale and Cabbage – While not traditional flowers, these plants add texture and color to the garden during the cooler months.

Planting Tips for October Sowings

To ensure successful growth, follow these tips:

  • Choose a well-draining soil enriched with compost.
  • Sow seeds indoors in seed trays if the weather is too cold or unpredictable.
  • Plant directly into the garden once the soil has cooled and nighttime temperatures are consistently above 40°F (4°C).
  • Water regularly but avoid overwatering to prevent root rot.
  • Apply a layer of mulch to protect young plants from frost and conserve moisture.

Additional Considerations

Keep an eye on the weather forecast. If a hard frost is expected, consider covering tender plants with frost cloths or bringing potted plants indoors. Regularly deadhead spent flowers to encourage continued blooming.

Conclusion

Sowing these annuals in October can greatly enhance your Zone 7 garden, providing color and interest during the cooler months. With proper planning and care, you can enjoy a vibrant garden that transitions beautifully from fall into winter.
