Soil quality is the secret behind thriving gardens. The key to good soil quality is composting, the process of turning food scraps and yard waste into natural fertilizer. Compost nourishes plants with essential nutrients like nitrogen, phosphorus, and potassium, and it also helps soil retain water, promotes beneficial microbes, and supports a healthier ecosystem. Through composting, you can help your flowers and plants grow better and avoid throwing food scraps into the trash.
Composting Enriches the Soil
Compost adds organic matter that enhances the texture and nutrient content of your soil. Rich compost makes heavy clay soil easier for roots to penetrate, and it helps sandy soil retain moisture. It also encourages soil stability, preventing compaction and erosion to aid the formation of strong root systems.
Composting Suppresses Disease
Compost is full of beneficial microbes that suppress harmful soil pathogens and fungi. These microbes outcompete disease-causing organisms, creating a protective barrier around plant roots. Naturally disease-resistant soil helps prevent root rot, blight, and other common problems without harmful chemicals.
Composting Discourages Weeds and Harmful Plants
A layer of compost can suppress weed growth by blocking light and creating an unfavorable surface for weed seeds to germinate. It also helps garden plants grow stronger and faster, giving them a competitive edge over persistent weeds.

Composting Makes Watering More Beneficial
The texture of compost helps soil to retain moisture longer, reducing runoff and evaporation. And mixing compost into your soil helps to aerate it, improving drainage through the ground into the water table below. The result is that plant roots get just the right amount of water. Compost strengthens the soil's ability to withstand both droughts and heavy rainfall, promoting healthier, more resilient plants.
Composting Supports Biodiversity in Your Garden
Healthy compost provides a welcoming home for beneficial bacteria, fungi, insects, and worms that all work together to support plant growth and natural pest control. Microorganisms break down organic matter and release essential nutrients, making them more available to plants. Earthworms and insects aerate the soil, improve drainage, and mix composted material deeper into the root zones. Meanwhile, certain fungi in compost create symbiotic relationships with plant roots, enhancing their ability to absorb nutrients and water. And even above ground, biodiversity increases: Pollinators such as bees and butterflies are more attracted to healthy, well-fed flowers.
How to Compost for Your Garden
To get started composting at home, select a spot in your backyard for your compost bin or pile. Good drainage and air circulation are essential. Once you have a place to make compost, layer coarse materials like twigs or straw at the bottom to keep airflow steady. Then, add the rest of the material. Balancing "greens" (like fruit scraps, cut flowers, and grass clippings) with "browns" (like dead leaves and cardboard) at roughly a 1:3 ratio promotes rapid decomposition and odor control. If the pile feels too dry, add greens or water the pile lightly. If it's soggy, mix in more browns to restore balance.
Turn the pile weekly to aerate it; oxygen fuels the microorganisms responsible for composting. Over a few weeks or months, you'll see the pile turn into dark, crumbly compost. Then, you can add it directly to your garden bed or top-dress around your flowers or vegetable plants.
