With a little forward-thinking, you can transform your household waste into garden gold to feed your plants and improve your soil condition. A compost bin quickly reduces vegetable peelings and organic waste into rich, valuable nutrients for your soil.

Simultaneously, a worm farm may reward you with black gold to feed your plants and improve your vegetable crops.

A little ingenuity

If you don’t have any room for larger composting facilities, then digging a hole in the ground and filling it with your scraps can quickly reward you with a rich planting area for the next growing season.

Alternatively, soaking the vegetable matter in a bucket of water helps produce a rich watering solution full of vital nutrients to keep your plants healthy.

Learning how to turn vegetable scraps into plant food may prove one of the most beneficial lessons you learn to improve your garden. It also helps you save the planet.

Why Is Organic Matter Good for the Garden?

Organic matter helps bind soil particles together, which makes the soil easier to dig.

Furthermore, soil with high nutrient content and a crumbly consistency is far better at holding onto valuable water and producing healthier plants and vegetables.

Natural benefits

Organic matter improves the soil by stimulating or feeding the life contained within it. By digging a natural organic fertilizer into your soil, you encourage natural bacteria, fungi, earthworms, and other beneficial organisms without which your plants may not survive or thrive.

Worms and natural bacteria break down the soil structure, which makes it easier for you to cultivate. Without worms in your garden, the soil becomes compacted and hardened.

Furthermore, the waste produced by the worms improves the structure of the soil and the nutrient levels. Consequently, a healthy worm population leads to nourishing soil.

Reap what you sow

When you grow vegetables, the plants use the natural nutrients and minerals found in the soil to grow. It’s the same with shrubs and flowering plants. If you don’t replace the goodness in the soil which the plants use to grow, the soil becomes barren and may not sustain life.

Learning how to turn vegetable scraps into plant food maintains the balance in the soil and allows you to replace the goodness in your garden to achieve successful agriculture.

Vegetables tend to be greedy plants, and while you may have a good crop the one year, if you don’t replace the goodness in the soil, you won’t get the same results the following year.

Perhaps you love your flowering shrubs and trees. The energy required to produce flowers and leaves comes directly from the ground and the sun.

While the sun takes care of itself, you need to take care of the ground. Without sufficient fertilizer, your soil may continue to deteriorate, and your plants may suffer.

Rotating Compost Bin

A compost bin represents one of the most efficient ways to transform your waste into usable, organic material. When you learn how to turn vegetable scraps into plant food, a rotating compost bin may provide the best place to start.

It takes approximately six weeks to achieve a usable mixture to apply around your plants or dig into the soil. However, you can use an organic compost accelerator to help speed up the process.

What is a rotating compost bin?

The unit consists of a large drum, usually made from durable plastic, set onto a sturdy metal frame with a turning handle. You place your vegetable scraps inside the drum and turn the drum once a week to keep the contents aerated.

After some six weeks, you end up with a natural, crumbly compost rich with natural goodness and nutrients. It proves the perfect mixture to use as a mulch around plants.

Furthermore, digging the compost into the garden improves the soil and adds valuable plant food to boost your flowers and vegetables.

How does it work?

A rotating compost bin proves useful all year round, unlike a compost heap, which may prove challenging to use during the winter months.

Tip your vegetable peelings and waste garden matter into the drum. I like to add a tiny amount of soil to mine, which adds natural bacteria to the mix.

Turn the drum every week to keep the texture light and to prevent the compost from compacting. The action of turning the drum adds valuable air to the mix and helps the waste break down.

A rotating compost bin represents an easy solution for your composting needs. It proves ideal for using up vegetable peelings. However, do not place cooked or dairy products within the composter because it may encourage vermin to infest your garden.

The more experienced or adventurous gardener may like the idea of Vermicompost.

Furthermore, this method proves one of the most efficient ways to use up waste and produces very high-quality plant food.

What is Vermicompost?

Vermicompost is plant food made using worm farms. While it may sound a bit squeamish, the process produces a liquid feed for your garden and containers that proves highly effective.

Furthermore, a colony of 500 worms may eat up to 2 pounds of waste a week, making a worm farm an efficient form of composting.

How does it work?

A worm factory consists of layers of plastic trays with drill holes in the base of each tray. Most worm farms or factories use a tap at the bottom of the stack from which you drain your liquid garden gold.

You fill the trays with layers of shredded newspaper and a colony of worms. The worms break down the scraps and newspaper.

As the contents break down, it releases liquid from the decomposing waste and the worms. The liquid collects at the bottom of the farm, where you use the tap to drain it away.

The resultant liquid proves a highly potent form of liquid fertilizer for your plants and makes a fantastic leaf feed when diluted with water.

Furthermore, as the worms break down the food, it forms an excellent crumbly compost, which you can remove to use on your garden and in your soil.

Before you remove the trays’ contents, it is essential to rescue as many of the worms as possible. While you may lose some of the colony into the garden, they quickly reproduce inside the factory.


Mealworms make excellent natural compost makers. You may wish to use specialized mealworm bedding to help build your colony and create a healthy, natural environment within your worm farm.

Mealworm bedding contains additional beneficial nutrition for your colony. However, unlike common worms, mealworms don’t create valuable worm castings for your compost.


The advantage of using mealworms in a worm farm is the frass they produce. Frass is the natural liquid by-product excreted by the worms, which proves highly nutritious to feed your plants.

Once you set up your worm farm and establish your colony, the frass collects in the bottom of the farm, and you drain it away by using the built-in tap.

The solution makes a superb plant feed when diluted with water. Furthermore, use the diluted solution as a leaf feed to boost the health of your plants.

Important note

Don’t use cooked, greasy, or dairy waste in your worm and mealworm farms. Use only those waste materials that you would consider for a rotating drum composter.

Bokashi Composting

When you learn how to turn vegetable scraps into plant food, Bokashi composting may seem new to you. However, it proves a highly efficient and easy way to transform your food waste into beneficial garden fertilizer.

The method requires very little equipment and uses a sizeable airtight drum to create the magic. It is worth using rubber gloves when handling the contents to avoid allergic reactions or rashes.

What is Bokashi composting?

Bokashi compost is fermented compost. Food waste, including cooked items such as meats, is added to an airtight container.

By adding layers of food waste to water creates a mixture that turns into a brackish solution. The constant addition of vegetable matter and food waste with water causes the mixture to ferment.

Efficient and nutritious

By adding layers of waste and topping it up with water, you can quickly fill a container. The lid must remain tightly fitted at all times, and while you may expect the mixture to stink, it gives off a mild scent like pickles or molasses.

The advantages of Bokashi composting derives from its space-saving nature. You may use items such as meat scraps, dairy products, and nutshells. Furthermore, it takes up very little room in your garden.

When filled, it takes approximately two weeks for the fermenting process to create a fantastic natural fertilizer for your garden.

Dig a Hole

Perhaps you have a small garden and don’t have room for composters. Dig a hole or trench where you intend to grow your produce next year and fill the trench or hole with your vegetable waste.

Method to the madness

The last thing you want is to see rodents rushing into your garden to remove the vegetable waste from your prepared hole or trench.

Once you have thrown in your peeling, cover the waste with a little loose soil and dampen it with water. The action should deter the little devils from stealing your scraps.

By sprinkling a little soil over the waste and adding water, you gradually build up layers of composting goodness. The scraps should start to decompose and enrich your soil accordingly.

Consequently, anything you plant in the area should thrive and produce a healthy bounty of fruit, vegetables, or flowers.
