by

Gardening in Zone 3 presents unique challenges due to its short growing season and cold winters. However, gardeners can still enjoy vibrant, colorful gardens by choosing the right plants. Self-sowing annuals are an excellent option because they naturally spread and reseed themselves each year, reducing the need for replanting and maintenance.

What Are Self-Sowing Annuals?

Self-sowing annuals are plants that drop their seeds naturally, allowing new plants to grow in subsequent seasons without human intervention. These plants are ideal for gardeners who want a low-maintenance garden that flourishes year after year. They adapt well to the climate of Zone 3, provided they are chosen carefully.
