✅ Why Compost Is Essential for Raised Beds
Unlike in-ground beds, raised beds don’t benefit from native soil life. That’s why it's critical to build a healthy, living soil from scratch—and compost is the key.
Compost improves:
Soil structure (boosts drainage and aeration)
Nutrient levels (natural slow-release fertilization)
Microbial life (essential for plant health)
Water retention (especially in hotter climates)
? Best Types of Compost for Raised Beds
1. Homemade Compost
Made from kitchen scraps, leaves, grass clippings, and yard waste, this is the most cost-effective option if you compost at home.
Don’t have a compost system yet? Consider a Garden Tower, which composts vertically and feeds your plants directly.

2. Mushroom Compost
A byproduct of mushroom farming, this compost is high in organic matter and great for soil structure. Avoid using too much, as it can be salty.
3. Vermicompost (Worm Castings)
Worm compost is rich in beneficial microbes and nutrients. A little goes a long way in boosting soil fertility.
4. Composted Manure
Manure from cows, chickens, or horses adds plenty of nitrogen—just make sure it’s well-aged and fully broken down.
5. Commercial Organic Compost Mixes
These store-bought blends usually include composted bark, manure, and other organic matter. Choose certified organic mixes for best results.
? How to Layer Compost in Raised Beds
Use the “Lasagna Method” to layer your raised bed for optimal fertility:
Base layer – Coarse sticks or straw for drainage
Brown materials – Leaves or shredded paper
Green materials – Grass clippings or kitchen scraps
Compost layer – 4 to 6 inches of quality compost
Topsoil mix – Blend compost with loam or potting soil on top
If you’re short on compost, a system like the Garden Tower helps you compost in place while growing veggies in vertical tiers.

? What to Avoid in Raised Bed Compost
Fresh manure (can burn plants)
Compost with non-organic waste or pesticides
Incomplete compost that still smells or has recognizable chunks
When in doubt, go with a blended mix or supplement your raised bed with worm castings or bokashi-prepared scraps.

? Final Thoughts: Choose Compost That Builds Soil for the Long Term
When it comes to raised beds, not all compost is created equal. Aim for a mix of homemade, organic, and specialty composts like worm castings for the best results. Whether you buy it bagged or produce it yourself, the key is building living soil that supports nutrient cycling and plant health.
