This One Composting Trick Can Save You $85 on Soil and Plants in 30 Days

Have you ever stood in the gardening section of a home improvement store and felt your wallet quietly cry? You need a bag of potting soil, you check the price, and suddenly you are wondering why dirt costs so much.

Then comes the fertilizer. Then maybe mulch. Before you know it, a small gardening trip has turned into a very expensive one.

But what if the things you throw away every day could help you cut that cost?

Your kitchen scraps can do more than fill up the trash. They can help improve your soil, support your plants, and save you real money at the same time.

I tried it myself, and once I stopped seeing banana peels and coffee grounds as waste, I started seeing them as gardening gold.

One thing I learned is that home composting is not just good for the planet. It can also bring down your gardening costs faster than you might expect.

In this post, I will show you a simple composting trick that helped me save $85 on soil and plants in just 30 days. Even if you have never composted before, this is easy to follow and beginner friendly.

In a nutshell, how I saved $85 in 30 days

Here is the short version of what happened.

• I started composting kitchen scraps at home instead of throwing them away.
• I used the finished compost to improve the soil for my potted plants and small garden beds.
• That homemade compost replaced the need to buy potting soil, fertilizer, and mulch.
• In one month, I saved a total of $85.

To make the savings easier to see, here is the breakdown.

Why composting saves you real money

You might be thinking, can a few eggshells really replace a bag of soil? The answer is yes, and here is why.

Gardening is really about soil health. Plants need nutrients to grow. When you buy soil from the store, you are paying for dirt plus nutrients.

When you buy fertilizer, you are paying for a concentrated nutrient boost. When you buy mulch, you are paying for material that protects the soil.

Compost helps with all three. It is a natural, complete package.

From my own experience, a small 30 day compost cycle can replace a bag of soil altogether. Since you are making it from things you already have, like kitchen scraps, coffee grounds, and yard clippings, the cost is basically zero.

There is also an environmental bonus. When food scraps go to the landfill, they break down without oxygen and create methane, a harmful greenhouse gas. When you compost at home, you turn waste into a useful resource. That is a win for your wallet and the planet.

Let me walk you through exactly how I did it.

I tested 7 indoor compost bins so you don’t have to. After fruit flies, stink bombs, and sludge, Here are the 3 game changers that are worth buying.

Step 1: Collect your kitchen scraps

This is the easiest part because you are already making these scraps. You just need to start saving them.

What to include:

• Fruit and vegetable peelings, like banana skins, apple cores, and potato peels
• Coffee grounds and paper filters
• Eggshells, rinsed first
• Tea leaves and tea bags, as long as the bag is paper and not plastic
• Spoiled greens from the fridge, like soft spinach or wilted lettuce

What to avoid:

• Meat, bones, and fish
• Dairy products, like cheese, yogurt, and milk
• Oily or greasy foods
• Pet waste

A simple beginner tip is to keep a small container on your kitchen counter. It can be a compost bin, an old ice cream tub, or even a bowl. As you cook, toss the scraps in there instead of the trash. At the end of the day, take the container outside to your compost pile. It becomes a habit very quickly.

Step 2: Set up your compost bin

You do not need a fancy system to start composting. You just need a place for the scraps to break down.

Here are a few beginner friendly options:

• Outdoor pile or bin: If you have a yard, you can choose a corner and start a pile. You can also buy a plastic bin or build one out of wood pallets.
• Tumbler bin: These are easy to spin and help mix everything well. They also keep animals out.
• DIY bin: A large plastic storage tote with holes drilled in the lid and sides can work perfectly for a small space.
• Indoor composting: If you live in an apartment, vermicomposting with worms is a great option.

The layering method makes compost work well. Think of it like making lasagna.

Green materials are your wet scraps, like kitchen scraps, coffee grounds, and fresh grass clippings. They provide nitrogen.

Brown materials are your dry items, like dried leaves, shredded newspaper, cardboard, and straw. They provide carbon.

A good rule is to use about two to three times more browns than greens. That helps with airflow and reduces smells.

Step 3: Maintain your compost

Once your pile is set up, it only needs a little attention to do its thing.

• Turn it: Every few days, stir the pile with a shovel or stick to add oxygen and speed things up. If you are using a tumbler, just spin it.
• Keep it moist: The pile should feel like a wrung out sponge. Damp, but not soaking wet. If it is too dry, add water. If it is too wet, add more browns.
• Watch the smell: Healthy compost smells earthy, like a forest floor after rain. If it smells rotten, it probably needs more browns or more turning.

Step 4: Harvest and use your compost

This is the fun part. After about 30 days, especially with a small batch of kitchen scraps, you should start seeing results. The scraps break down into a dark, crumbly material that looks a lot like rich soil.

How to harvest:

If you are using a bin, stop adding new scraps for a week or two so it can finish breaking down. Then scoop out the finished compost from the bottom. If you are using a pile, you can sift it through a mesh screen to separate the larger pieces, which can go back into the next batch.

How to use your black gold:

• Potting soil mix: Mix compost with regular garden soil or cheap potting soil. A 50 50 mix works well for potted plants.
• Top dressing: Sprinkle compost on top of the soil around your plants. Water it in and it acts like a slow release fertilizer.
• Soil conditioner: Work compost into your garden beds before planting to improve soil structure and help the soil hold water.

How I Arrived at $85

Let us look at the numbers again.

• Potting soil: I would normally buy a 20 pound bag of good quality potting mix for about $50. Instead, I mixed homemade compost with leftover garden soil. Saved: $50.
• Fertilizer: I usually buy organic fertilizer pellets or liquid plant food. My compost gave my plants the nutrients they needed for the month. Saved: $20.
• Mulch / soil conditioner: I use mulch to keep soil moist and healthy. Compost did the same job. Saved: $15.
• Total savings: $85 in 30 days.

Tips for beginners

If you are just starting out, keep it simple. You do not need a giant compost setup to get good results.

• Start small with one bin.
• Keep adding scraps regularly.
• Chop scraps into smaller pieces so they break down faster.
• Use a compost thermometer if you want to track heat more closely.

Common mistakes to avoid

• Adding meat or dairy
• Letting the pile get too dry or too wet
• Forgetting to turn it
• Giving up too soon

If your pile looks inactive after two weeks, do not panic. Compost takes patience. The microbes are still working even when you cannot see much happening.
