Greenhouse gardening allows you to grow plants year-round in a controlled environment, expanding your growing capacity and enabling better plant care. It is suitable for both beginners and experienced gardeners, providing the tools to extend the growing season and maximize harvests. 

For many gardeners, February may still be winter. But inside a greenhouse, it’s a time of growth and preparation. Whether you’re growing vegetables, herbs, or flowers, a greenhouse offers the perfect environment to get a head start on the growing season. Here’s how to maximize your planting potential this month.
