Are you an avid gardener? Are you dedicated to producing quality produce or an enviable garden? Studies have shown that not only is composting an excellent way to help the environment to reduce the carbon surplus that the earth experiences, but on a local level, it is an easy and affordable way to enrich the soil in your garden or yard. According to the United States Environmental Protection Agency (EPA), “food scraps and yard waste currently make up more than 28% of what we throw away.”[i] Of course, while not all of that material can be reused in a compost, imagine what a reduction in even a small percentage of that number could do for our planet and for the soil!
As interest in preserving the environment grows, more people have become interested in how they can do their part. One of the many ways is through composting, or more specifically, posthole composting, which is more than a simple solution for waste reduction.
While you may have heard of the process of collecting organic material and allowing the organic material to decompose, which is known as composting naturally, this much simpler form of recycling is less well-known. Posthole composting is the process of using common kitchen scraps to fertilize and enrich a small area of land or dirt and to encourage nature’s workers to convert organic material into usable soil. It is simple, cost-effective, and provides your garden with invaluable nutrients.
Advantages Of Posthole Composting
Although it may not be the right option for everyone, posthole composting has many amazing advantages:
Traditional composting requires the use of a compost bin or pile. When you think about composting, you may think of a yard with a large pile of leaves, a compost tumbler or bin, or even a 55-gallon barrel requiring constant turning, maintenance, and feeding. On the other hand, posthole composting can be as expansive or scaled-down as you want it to be. No bin or pile is required. All you need is a small bucket to store your organic kitchen scraps such as fruit and vegetable peels, eggshells, and even coffee grounds.
Posthole composting does not require any special containers, location, or a large amount of space. You can compost wherever you expect to plant trees, shrubs, flowers, or vegetable plants. Even raised beds are a good place for posthole composting. All you need is a shovel and your kitchen scraps.
Composting requires the right environment: right temperature, an appropriate amount of moisture, the right organic material, and aeration. This last one may be a stretch for your mind, but a compost pile needs to be regularly disturbed and turned to speed up the decomposition process. When posthole composting, no maintenance or special conditions are required.
Earthworms, although seldom thought of, play a vital role in the world’s ecosystem. Earthworms add value to the composting process and help to speed up decomposition. Earthworms are attracted to the organic material in your compost hole and will flock to the soil in your garden. As they digest the organic material, they also leave behind feces, which provides additional fertilization. They also help to aerate and turn over the soil as they travel along. By digging your posthole 8 to 12 inches deep, you are placing the organic material right in the middle of the worms’ habitat. They will love you for it, and more importantly, the soil will receive the valuable nutrients produced through the process.
Does the cost of keeping your garden beautiful and lush keep you from doing it? Store-bought fertilizers can be expensive and, in some cases, harmful to the environment. Posthole composting is not only inexpensive but more importantly, it’s FREE. In theory, you are recycling waste from things that you already purchased and consumed.
Composting is also a great way to save on the cost of trash collection and space in landfills. By recycling household waste, you are reducing the amount of trash that will now be sent off to a landfill to rot amongst the old tires, cell phones, and water bottles.
Are you concerned about global warming? As the earth’s landfills reach capacity, overflowing into streams, rivers, and the ocean, more and more methane gases are released into the air at an alarming rate. By reducing the amount of organic material from the landfill by composting, you not only reduce the amount of space required in a landfill, as mentioned earlier, but it has the added benefit of reducing the volume of gases that seep into the atmosphere. Aside from the benefits to the soil in your yard, imagine how much you can reduce your carbon footprint by following this simple process.
Let’s be honest. You are very busy, and gardening can be time-consuming in and of itself. You may not have the time to be constantly turning, maintaining, and feeding your compost pile. It takes work! The beauty of the posthole compost is that all it takes is a few scraps from the kitchen and something to dig with. Nothing fancy required and no large time commitment. Just cover up your hole with soil, and you are finished! During the spring and summer, when the ground is not frozen, the entire process should require no more than 5 minutes yet provide substantial value to your garden or yard.
Water is, of course, a critical factor in how your garden or flower beds will grow. Compost helps the soil to retain water so that it can be used when external sources of water may not be available. The organic materials absorb the water and allow the plants to draw from it in between rainfall or watering.
Another advantage to posthole composting is that because of the relatively small amount of organic materials that you are using and assuming the right conditions, and your compost should decompose in a relatively short amount of time, from several weeks to just a few months. Within no time at all, the fruit of your efforts will be enriching the soil and providing valuable nutrients to your plants.
Sometimes referred to as the Dig and Drop Method, posthole composting is very simple. As the title suggests, ‘dig’ a hole wherever you want to place your garden, plants or trees, ‘drop’ in your organic material such as potato skins and eggshells, and top it with soil!
Lastly, vital nutrients are delivered directly to the roots of your plants. What better method of fertilizing your plants than from the source, from the ground up!
Words of Caution For Posthole Composting
While there are a vast number of advantages to posthole composting, I will also caution you about several things to avoid doing in the process.
- Be sure to dig your hole at least 8 inches deep but no more than 18 inches to prevent animals from catching the scent of the decomposing materials and dig it up. The deeper the hole, the more likely that the nutrients will simply seep into the groundwater, not providing your plants with any of their life-giving value. The best place for your scraps is in this area between 8 and 18 inches below ground level, where it will still receive water, yet the valuable nutrients will not be in jeopardy of being washed away.
- It is not recommended that meat or dairy products be included in your scrap bucket to be composted as the strong scent of rotting meat will draw rodents and dogs to your compost hole. Besides the fact, the odor will be highly unpleasant to you and your neighbors!
- Be sure to chop up kitchen scraps into small pieces to promote the decomposition process. Onions and potatoes, in particular, tend to sprout new shoots before they begin to decompose. Even the onion skins may be a bit tough on the process, so be sure that they are wet before putting them into your posthole.
We have briefly mentioned the types of things to add to your compost hole, but let’s look at it a little “deeper.” Meat and dairy products should not be included in your compost mix nor grease and bones. Not only would animals be attracted to your yard and potentially dig up your flower beds, but these materials require a much longer time to decompose.
Compostable Items To Posthole Compost
So, what exactly should you be putting into your kitchen scraps bucket? If you are like me, you have a small bucket the size of a children’s sand toy neatly stashed in your kitchen. As you go about your daily routine, cutting, chopping, consuming, you can toss the scraps into this bucket, allowing for easy, small quantity composting. In other words, one bucket, one posthole. You should chop or break up any large pieces to ensure that they break down quickly and easily. For example, crush eggshells to speed up the process.
What do I include?
- Vegetable and fruit skins, rind and core
- Leafy greens
- Coffee grounds (toss the filter in there too!)
- Old bread
- Peanut shells
- Tea leaves
- Cut flowers
You may also want to include other household waste, such as:
- Black and White newspaper (color or glossy newspapers will not break down the same way)
- Pet and human hair
- Cardboard cut into small pieces (remove any shiny material or plastic/tape as this is not biodegradable)
- Ash (wood only)
How-to Posthole Compost
Posthole composting is an amazing, environmentally friendly way of enriching your garden and yard. To supplement the organic material, you can also add small amounts of organic fertilizer, such as alfalfa pellets, to speed up the decomposition process. When filling your posthole, be sure to casually toss in the organic material rather than compact it down. Space allows it to breathe and encourages microorganisms to congregate. Before covering the kitchen scraps with the soil that you removed, consider placing the grass or weeds that you removed when digging the hole on top, upside down, adding their nutrients and organisms to the composting process.
In my list of compostables above, you will see, pet and human hair. Although this is not necessarily a “kitchen scrap,” it does provide several added benefits in your posthole compost; hair helps to deter rodents from trying to gobble up the rotting delicacies that you have buried, and it slowly releases nitrogen, which is a crucial ingredient in turning your discarded food into nutrient-rich soil.
To the seasoned home gardener, posthole composting may seem inferior to traditional composting. However, the result is the same, an organic mixture that not only enriches and fertilizes the soil but also helps to save our planet, mother Earth, for future generations. Whether you plant right away on top of the organic material or you wait until it has decomposed, the composting process will certainly enrich the quality and beauty of your garden or produce.
“Reduce, Reuse, Recycle” is the EPA’s promotion phrase to save money, energy, and natural resources. If every one of us were to attempt to follow this simple slogan, we could make a dramatic difference in the environment, the quality of our soil and those things which it produces and certainly, improve the quality of life for all of us. Composting is each person’s small contribution to reduce, reuse, and recycle.
Posthole Composting A Summary
Posthole composting is not only inexpensive and ecologically sound, posthole composting may be the perfect option for gardeners but may have limited space, time, resources, and energy! There is no right or wrong in posthole composting, but rather it is simply part of nature’s recycling program. Posthole composting’s creates homemade fertilizer, which provides your garden with the nutrients needed to thrive and grow. You are just facilitating the decomposition process. Happy composting!
