Can I use fresh horse manure on my garden?
Fresh manure from horses should not be used directly on your garden beds, especially not on vegetable gardens because of the presence of pathogenic bacteria.
Adding fresh horse manure to your garden will add a lot of nutrients but also carry bacteria and weed seeds with it, which can cause damage to your garden in the long run.
The best way to use horse manure is to compost it first before using it on your garden.
Composting is the natural process where decaying organic matter breaks down into rich humus.
The humus can then be used as fertilizer to enrich your garden beds.
How to compost horse manure
To compost horse manure, pile up the manure and let it sit for at least 3 to 4 months until it starts to decompose and become softer.
You can add other types of compostable materials to the pile including coffee grounds, newspaper, grass clippings and vegetable scraps.
Anything that you would put in a standard compost pile will be a good addition to your horse manure composting process.
Turn the pile every week and keep it relatively moist to speed up the decomposition process.
The compost heap should heat up to at least 176°F (80°C) and stay at that temperature for a couple of weeks.
You can use a soil thermometer to check the temperature of your compost pile.
The heat produced during the composting process will get rid of most of the weed seeds as well as any harmful bacteria that may be present in the manure.
The longer it sits, the better quality the compost will be.
The compost can then be used as a mulch around your plants to enrich the soil, added to raised garden beds or dug into your garden beds before planting.
Can horse manure be used on flowering plants?
Horse manure is rich is nitrogen but low in phosphorus and potassium, which means it’s not a good fertilizer choice for flowering plants like roses, tomatoes, peppers and other plants that produce flowers.
You can use horse manure to enrich the soil around your flowering plants but you’ll need to combine it with a high phosphorus or potassium source such as bone meal, dry molasses or fish emulsion.
Where to get horse manure
If you have horses on your ranch or farm, then you have plenty of fresh horse manure available every day.
You can also buy horse manure from local stables, riding schools or horse breeders.
How much horse manure do I need?
The amount of horse manure needed will depend on how much compost you want to make, as well as the size of the area that you are going to fertilize.
The general rule is that you need about 20 lbs (9 kg) of horse manure for every cubic yard (about 1 m³).
Does composted horse manure smell?
After the composting process is complete there will be no smell so you can use it on your gardens without having to worry about offensive odors.
