🗓️ Why You Need a Gardening Calendar (Even in an Apartment)

Urban gardening isn’t like traditional farming — you don’t have fields or seasons dictating your rhythm. Instead, you rely on artificial light, microclimates, and creativity.

But without structure, it’s easy to forget when to start seeds, trim herbs, or refresh soil.

A seasonal calendar brings order to the chaos. It turns gardening from a sporadic chore into a sustainable habit.

And according to the Royal Horticultural Society, gardeners who follow a planting schedule report higher success rates and greater satisfaction.

So whether you’re growing basil on a kitchen counter or strawberries on a fire escape, this 2026 calendar will keep you on track.

🌱 Final Thought: Your Garden Grows With You

A calendar doesn’t just tell you what to do — it shows you how far you’ve come.

Each checked box, each new leaf, each harvested sprig of thyme is proof that you showed up.

In 2026, may your garden be more than a hobby. May it be a companion, a teacher, and a quiet celebration of growth — yours and nature’s.
