Did You Know?

1. Bonsai trees: While many plants benefit from the nutrient-rich properties of horse manure, bonsai trees are an exception. This is because they require a delicate balance of nutrients and horse manure can introduce excessive levels of nitrogen, causing the trees to grow too rapidly and lose their desired miniature size.

2. Orchids: These elegant flowers are known for their finicky nature, and horse manure can be detrimental to their growth. Horse manure tends to be too rich in nutrients for orchids, leading to an overabundance of foliage and a lack of blooming.

3. Carnivorous plants: Despite their exotic and unique nature, carnivorous plants, such as Venus flytraps and pitcher plants, do not appreciate horse manure. These plants have evolved to obtain nutrients from insects and other small organisms, making them ill-suited to utilize the nutrient composition of horse manure effectively.

4. Alpine plants: Adapted to survive in harsh mountainous environments, many alpine plants have specific preferences when it comes to soil composition. Horse manure, due to its relatively high organic matter content, can retain too much moisture around the roots of alpine plants, leading to root rot and eventual death.

5. Ferns: While ferns generally thrive in moist and nutrient-rich environments, they are not particularly fond of horse manure. Ferns prefer a more acidic soil pH, which is often disrupted by the alkaline properties of fresh horse manure. Consequently, it is best to avoid using horse manure as a fertilizer for these delicate and ancient plants.

Plants That Don’t Like Horse Manure

When using horse manure as a fertilizer, it is important to note that not all plants will benefit from its application. Some plants have specific requirements or sensitivities that make horse manure unsuitable for their growth. Here are a few types of plants that generally don’t appreciate horse manure:

  • Acid-loving plants, such as azaleas, rhododendrons, and blueberries. These plants prefer acidic soil conditions, whereas horse manure tends to have a more neutral to slightly alkaline pH.

  • Shallow-rooted plants, like lettuce and strawberries. Horse manure, if not properly composted, can be too strong and potentially burn the shallow roots of these delicate plants.

  • Native or wildflowers. These plants often thrive in poor soil conditions and do not require the nutrient-rich environment that horse manure provides.

  • Water-loving plants, such as water lilies and ferns. Horse manure can make the soil too heavy and waterlogged, causing root rot in these moisture-sensitive plants.

  • Succulents and cacti. These plants are adapted to arid environments with low nutrient availability. Horse manure can over-fertilize them and disrupt their natural growth patterns.

Wildflowers

Wildflowers are renowned for their ability to adapt to various soil conditions. However, horse manure can disrupt their natural growth. These delicate and diverse plants usually thrive in low-fertility soils, which makes the nutrient-rich environment created by horse manure too overwhelming for their preferred habitat.

Drought-tolerant plants

Plants that are adapted to survive in dry conditions, such as cacti and succulents, do not appreciate the moisture-retaining properties of horse manure. These plants have evolved to store water efficiently and prefer free-draining soil that allows excess water to flow away quickly, avoiding the risk of root rot.

  • Cacti and succulents are adapted to dry conditions
  • They store water efficiently
  • They prefer free-draining soil to avoid root rot
  • Horse manure retains moisture which these plants do not need

These plants have evolved to store water efficiently and prefer free-draining soil that allows excess water to flow away quickly, avoiding the risk of root rot.

Plants that require free-draining soil

Similarly to drought-tolerant plants, plants that require free-draining soil (such as lavender or rosemary) can suffer from the water-holding capacity of horse manure. These plants thrive in soil that allows water to percolate through, preventing waterlogged conditions that may lead to root diseases.

  • Drought-tolerant plants
  • Plants that require free-draining soil
  • Lavender and rosemary

“These plants thrive in soil that allows water to percolate through, preventing waterlogged conditions that may lead to root diseases.”

Plants that thrive in nutrient-poor soils

Contrary to what one might think, not all plants benefit from excessive nutrient availability. Some species, like certain types of moss or ferns, have evolved to thrive in nutrient-poor environments. Introducing horse manure, rich in nitrogen and other nutrients, can disrupt the delicate nutrient balance these plants have adapted to, potentially harming their growth.

Root vegetables like carrots and parsnips (on freshly manured soil)

While horse manure can be beneficial for many plants, it has some limitations when it comes to root vegetables such as carrots and parsnips. These crops are sensitive to fresh manure due to its high ammonia content, which is a byproduct of the decomposition process. The intense levels of ammonia in fresh manure can actually burn the roots of these plants.

To avoid damaging the root vegetables, it is best to let horse manure decompose for a while before using it as a fertilizer. This process helps to reduce the ammonia levels, making the manure safer for sensitive crops like carrots and parsnips.

In addition to decomposing the manure, it is also advisable to mix it well with soil or compost before applying it to the garden. This ensures that the nutrients from the manure are evenly distributed, and it reduces the risk of concentrated amounts of ammonia coming into direct contact with the roots.

Furthermore, it’s important to note that fresh manure should not be used on any crops that are close to harvest time. It’s recommended to wait at least 120 days between the application of fresh manure and the harvesting of root vegetables.

In summary, while horse manure can be beneficial for many plants, it should be used with caution when it comes to root vegetables like carrots and parsnips. To minimize the risk of root burn, let the manure decompose, mix it well with soil or compost, and avoid using fresh manure close to harvest time.

  • Let horse manure decompose before use
  • Mix manure well with soil or compost
  • Avoid using fresh manure close to harvest time

“Fresh manure can burn the roots of sensitive root vegetables like carrots and parsnips.”

Plants That May Benefit From Well-Rotted Horse Manure

Although horse manure may not be suitable for all plants, there are several species that can greatly benefit from its application in the garden. One such plant that thrives with the use of well-rotted horse manure is the Rose. Rose plants require nutrient-rich soil to produce vibrant blooms, and horse manure provides the necessary organic matter and essential nutrients for their growth. When well-rotted, horse manure improves the soil’s structure and water-holding capacity, promoting healthy root development and overall plant growth. Adding a layer of well-rotted horse manure to the base of roses during planting or as a top dressing throughout the growing season can significantly enhance their health and vigor. It is important to ensure that the manure is aged and composted properly to prevent any adverse effects on the plants. So, for those looking to cultivate beautiful roses, incorporating well-rotted horse manure into their garden practices can be highly beneficial.

Roses

Roses are often celebrated as the queens of the garden, and their beauty can be enhanced by the addition of well-rotted horse manure. This organic fertilizer provides a slow release of nutrients, including nitrogen and potassium, which are essential for roses to produce vibrant blooms. The well-rotted horse manure improves soil structure and water retention, ultimately promoting healthier and more robust roses.

Fresh Horse Manure Is Not Suitable For Plants

While horse manure can be incredibly beneficial, it must undergo a composting process before it can be used safely on plants. Fresh horse manure contains high levels of nitrogen along with ammonia, which can potentially burn roots and stems, leading to plant damage. Therefore, it is best to let the manure mature and decompose before considering its use as fertilizer.

The composting process not only reduces the risk of ammonia burn but also helps eliminate potential pathogens that may be present in the raw manure. Microorganisms break down the organic matter, creating a stable and nutrient-rich product that can be safely applied to plants without fear of harm.

Potential Contamination In Horse Manure

It is crucial to consider the quality of horse manure before incorporating it into your garden. Horse manure, especially if sourced from non-organic farms, may contain traces of weed seeds, which can lead to unwanted plant growth. Additionally, if the horse has been fed hay or grass treated with herbicides, the manure might be contaminated with residual weedkiller, posing a risk to sensitive plants.

Therefore, it is essential to ensure that the horse manure you utilize comes from reliable sources. Organic farms that comply with strict regulations regarding feed and treatments can provide a safer and more desirable product for your garden.
