Using Rabbit, Horse, and Chicken Manure Safely in the Garden

Animal manures are excellent organic soil amendments, but the golden rule is simple: always use composted manure, never raw. Fresh manure harbors pathogens that can contaminate edible crops like tomatoes, posing health risks.

Why Composting Matters

Proper composting generates heat that kills harmful bacteria, parasites, and weed seeds. Once fully broken down, manure becomes a safe, nutrient-rich addition that improves soil structure, moisture retention, and microbial activity.

Manure Types at a Glance

• Rabbit manure: Considered a "cold" manure—lower in nitrogen, it can be used with minimal aging, though composting is still best practice.
• Horse and cow manure: "Hot" manures high in nitrogen; must be composted thoroughly (ideally a year or more) to avoid burning plants and to reduce salt buildup.
• Chicken manure: Very high in nitrogen; requires extended composting to prevent plant damage.

Best Practices

• Source manure from herbivores only.
• Compost in a managed pile, turning regularly to ensure even decomposition.
• Apply finished compost as a soil amendment or mulch.
• Avoid applying any manure directly to food crops shortly before harvest.

When in doubt, bagged composted manure blends from reputable nurseries offer a convenient, safe alternative. Building healthy soil is a long-term investment—composted manure is one of the best tools for the job.
