Certain plants thrive when given manure, especially those that are heavy feeders and require nutrient-rich soil. This includes vegetables like tomatoes, corn, squash, and leafy greens, as well as many flowering plants such as roses and dahlias. Manure acts as an excellent soil amendment, improving its structure, water retention, and fertility.

Understanding Manure as a Plant Nutrient Source

Manure is a fantastic organic fertilizer that enriches the soil. It provides essential nutrients like nitrogen, phosphorus, and potassium, which plants need for healthy growth. It also introduces beneficial microorganisms that improve soil health over time.

Why Do Some Plants "Like" Manure So Much?

Plants that are considered heavy feeders have a high demand for nutrients. They grow quickly and produce abundant fruits, flowers, or foliage, all of which require a steady supply of nourishment. Manure directly meets this demand, helping these plants reach their full potential.

For example, a tomato plant needs a lot of nitrogen for leafy growth and phosphorus for flowering and fruit development. Providing well-rotted manure ensures these nutrients are available throughout the growing season.

Types of Manure and Their Benefits

Not all manure is created equal. The type of manure can influence its nutrient content and how it should be used.

• Cow manure: A good all-around fertilizer, it’s relatively low in nitrogen and phosphorus. It’s often considered "cooler" and less likely to burn plants.
• Horse manure: Rich in nitrogen and potassium, it’s great for boosting growth. However, it can be "hotter" and may require composting to avoid damaging plants.
• Chicken manure: Very high in nitrogen, phosphorus, and potassium. It’s a potent fertilizer but must be composted thoroughly to prevent burning plant roots.
• Sheep manure: A balanced fertilizer, it’s rich in nitrogen and phosphorus. It’s considered a good all-purpose manure.

Important Note: Always use well-rotted or composted manure. Fresh manure can contain weed seeds, harmful pathogens, and can be too strong, potentially "burning" plant roots due to its high ammonia content.

Which Plants Benefit Most from Manure?

Many plants in your garden can benefit from the addition of manure. Here’s a breakdown of common categories:

Vegetable Garden Favorites

Vegetables are often the biggest beneficiaries of manure. Their rapid growth and fruit/vegetable production deplete soil nutrients quickly.

• Tomatoes: These sun-loving fruits are notoriously hungry. Manure provides the nitrogen for lush foliage and the phosphorus for abundant fruit set.
• Corn: Corn is a heavy feeder, especially of nitrogen. Manure helps ensure strong stalks and well-filled ears.
• Squash and Pumpkins: These vining plants require significant nutrients to produce large fruits. Manure fuels their vigorous growth.
• Leafy Greens: Lettuce, spinach, kale, and swiss chard need nitrogen for vibrant, healthy leaves. Manure is an excellent source.
• Root Vegetables: Carrots, potatoes, and beets benefit from improved soil structure and balanced nutrients that manure provides.

Flowering Plants and Shrubs

Many ornamental plants also appreciate the boost manure provides, leading to more blooms and healthier growth.

• Roses: These classic beauties are heavy feeders. Composted manure worked into the soil around roses encourages prolific blooming and disease resistance.
• Dahlias: Known for their large, showy blooms, dahlias require plenty of nutrients to produce such impressive displays.
• Peonies: While not as demanding as roses, peonies benefit from a yearly top-dressing of composted manure to support their lush foliage and large flowers.
• Fruit Trees and Berry Bushes: For improved fruit production and overall plant health, incorporating manure into the soil around established fruit trees and berry bushes is beneficial.

Lawn Care

While not a "plant" in the same sense, lawns also benefit from manure. Applying a thin layer of composted manure in the spring can revitalize grass, improve soil structure, and enhance water retention.

How to Properly Use Manure in Your Garden

Applying manure correctly is crucial to avoid harming your plants. The key is composting or aging.

Composting Manure

Composting manure with other organic materials is the best way to create a balanced, nutrient-rich amendment. This process breaks down the manure, kills pathogens and weed seeds, and stabilizes the nutrients.

A good compost pile often includes a mix of "greens" (nitrogen-rich, like manure) and "browns" (carbon-rich, like dry leaves or straw). Turning the pile regularly helps speed up decomposition.

Applying Aged Manure

If you don’t compost, ensure your manure is at least 6 months to a year old. It should be dark, crumbly, and have an earthy smell, not the strong ammonia odor of fresh manure.

• For new beds: Dig in a generous amount of well-rotted manure into the soil before planting. Aim for a 2-4 inch layer mixed into the top 6-8 inches of soil.
• For established plants: Apply a 1-2 inch layer as a top dressing around the base of plants, keeping it a few inches away from the stem. This is often done in spring.
• For potted plants: Use composted manure sparingly, mixing a small amount into potting soil to avoid over-fertilizing.

What NOT to Do with Manure

• Never use fresh manure directly on plants.
• Avoid piling fresh manure directly against plant stems or trunks.
• Do not over-apply, even well-rotted manure, as it can still lead to nutrient imbalances.

People Also Ask

### Can you put chicken manure directly on plants?

No, you should never put fresh chicken manure directly on plants. It is extremely high in nitrogen and ammonia, which can burn plant roots and foliage. Always compost chicken manure for at least 6-12 months or until it has a dark, crumbly texture and an earthy smell.

### Is cow manure good for all plants?

Cow manure is a gentle, all-purpose fertilizer that is beneficial for most plants. It’s less likely to burn roots than other types of manure. It improves soil structure and provides a steady release of nutrients, making it a great choice for vegetable gardens, flower beds, and even lawns.

### How long does manure take to break down in soil?

The time it takes for manure to break down depends on its type, how it’s applied, and soil conditions. Fresh manure can take several months to a year to fully decompose. Composted manure, already partially broken down, integrates into the soil much faster, typically within a few weeks to months.

### Can too much manure harm plants?

Yes, too much manure can harm plants. Over-application, especially of fresh or improperly composted manure, can lead to nutrient burn, root damage, and
