Window sill garden of herbs

Top 10 Medicinal Herbs For Your Windowsill Garden

Plants clean the air we breathe while also adding beauty through texture, colors and fragrance to your environment. Windowsill herb gardens were commonplace once upon a time. There is no better time to bring them back than in celebration for the budding life of the Spring season. Having plants in the home allows your family to have fresh flavors and nature’s medicine at the ready. First, listen to all your senses to discover which plants call to you. Then, plant what you will enjoy and use in your home to delight your taste buds and support healthy body functions.

Growing herbs and spices for countless uses can be easy and costs a fraction of the grocery store price. Most herbs grow well in a sunny spot with well-draining soil. It is easy to move from outdoor to indoor growing when you use pots or other containers. If grouping herbs, plant them together based on similar water requirements. For example, oregano, thyme, and rosemary prefer drier soils to share a planter comfortably.

Herb gardens are accessible for everyone! Even in a tiny house, you can grow your own bounty of medicinal herbs by using vertical space. Wall or windowsill herb gardens can grow with at least 6 hours of sunlight or place a grow light above the plants. Just give them enough space for growth and airflow. Growing indoors also allows you to cultivate a variety of non-native and dwarf varieties of plants that you could not otherwise grow. For example, growing your own aloe plant to help with minor kitchen burns. Or a dwarf moringa tree, known as the “Tree of Life'' because of its robust nutrient profile.
