“Don’t toss your eggshells” might actually be useful advice for gardeners preparing their home garden for spring 2027, but there’s a right way to do it. According to gardening experts featured by Martha Stewart, eggshells are rich in calcium and can be added to garden soil or compost, although they should be cleaned, dried and finely crushed because they take time to break down. Experts also recommend testing your soil first, since adding calcium isn’t necessary when your garden already has enough.And eggshells are only one thing worth saving this fall. Fallen leaves, compost and other organic material can all play a role in preparing healthier garden soil for the next growing season. For anyone hoping to grow wildflowers, native plants, vegetables or a pollinator garden at home, a few smart fall gardening habits can help get the ground ready long before spring 2027 arrives. And a story from one of our gardener readers shows exactly why.
