What Is Finished Compost?

Finished compost is the final product of decomposed organic matter. It’s rich in nutrients and beneficial microorganisms that can significantly enhance soil quality and plant health. Understanding what finished compost is helps us better appreciate its role in our garden.

Signs of Finished Compost

Determining whether our compost is finished involves checking for certain indicators:

Signs Details
Consistency It should be crumbly, like rich, dark soil.
Smell It should have an earthy smell, not a foul or sour odor.
Temperature The compost pile should no longer be hot and instead be at ambient temperature.
Visibility Original materials should be unrecognizable, except perhaps a few resistant items like small twigs.

Why Use Finished Compost?

Before we get into the how, let’s talk about why using finished compost is beneficial. Its advantages go far beyond just adding organic matter to the garden.

Benefits of Compost in the Garden

  1. Soil Enrichment: Compost is packed with essential nutrients, improving soil fertility.
  2. Improved Soil Structure: The addition of organic matter helps sandy soils retain moisture and helps clay soils drain better.
  3. Disease Suppression: The beneficial microbes in compost can help suppress soil-borne diseases.
  4. Water Retention: Helps soil retain water, reducing the need for frequent watering.
  5. Reduction of Waste: Using compost reduces the amount of organic waste going to landfills.

How to Use Finished Compost

Now, let’s get to the core of our discussion: how do we use finished compost in our garden? There are several effective methods, and choosing the right one depends on our specific gardening needs.

Top Dressing for Established Plants

Top dressing involves spreading a layer of compost directly onto the soil around existing plants. It’s perfect for giving established plants a nutrient boost without disturbing their roots.

Steps to Top Dress:

  1. Clear away any debris around the plants.
  2. Spread about 1-2 inches of compost around the base of the plants.
  3. Water the area after applying compost to help it settle.


Using compost as mulch helps retain moisture, regulate soil temperature, and suppress weeds. It’s a fantastic way to nurture our garden holistically.

Mulching Steps:

  1. Apply a 2-3 inch layer of compost around plants, leaving a small gap around the stems to prevent rot.
  2. For the best results, mulching should be done in the late spring or early summer.

Soil Amendment

Incorporating finished compost into the soil prior to planting can enhance its texture and fertility. This method is particularly beneficial for new garden beds.

Amending Soil Steps:

  1. Spread a 1-2 inch layer of compost over the entire planting area.
  2. Use a garden fork or tiller to mix the compost into the top 6-12 inches of soil.
  3. Level the area and it’s ready for planting.

Compost Tea

Compost tea is a nutrient-rich liquid made by soaking compost in water. It’s a quick way to give plants a nutritious boost, especially for those in pots or containers.

Making Compost Tea:

  1. Fill a large container with water.
  2. Put finished compost into a mesh bag or an old pillowcase and submerge it in the water.
  3. Let it steep for 24-48 hours, stirring occasionally.
  4. Use the resulting liquid to water your plants or as a foliar spray.

Seed Starting

Starting seeds in compost-rich soil gives them a nutrient-packed beginning, promoting strong growth and healthy plants.

Steps for Seed Starting:

  1. Mix finished compost with equal parts of potting soil or garden soil.
  2. Fill seed trays or pots with the mixture.
  3. Plant seeds according to package instructions.

Lawn Top Dressing

Applying finished compost to lawns helps improve soil quality and encourages lush, green growth. It’s a great way to maintain a healthy lawn without synthetic fertilizers.

Steps for Lawn Top Dressing:

  1. Mow the lawn to a moderate height.
  2. Spread a thin layer (about ¼ inch) of compost evenly over the lawn.
  3. Rake the compost to ensure even distribution.
  4. Water the lawn thoroughly.

Compost Application by Plant Type

Different plants have varying nutritional needs. Tailoring our compost application method according to plant type ensures optimal growth and health.

Vegetable Gardens

Vegetable gardens thrive with regular compost additions. Use compost both as a soil amendment before planting and as a top dressing throughout the growing season.

Flower Beds

Flower beds benefit from yearly compost applications in the spring or fall, enhancing soil fertility and encouraging vibrant blooms.

Fruit Trees

Compost supports fruit trees by improving soil structure and nutrient content. Apply compost under the canopy, away from the trunk, once a year.

Shrubs and Perennials

Applying compost around shrubs and perennials once or twice a year helps maintain soil health and supports continual growth.

Practical Tips for Compost Use

Incorporating compost into the garden can seem daunting, but a few practical tips can make the process smoother and more rewarding.

Don’t Overuse Compost

While compost is beneficial, too much can lead to nutrient imbalances. Aim for moderate applications to avoid overwhelming your plants.

Compost Quality Matters

Ensure your compost is fully decomposed before use. Unfinished compost can harbor pathogens and pests, which can harm your plants.

Seasonal Considerations

Applying compost in the spring or fall leverages the natural growing cycles of plants, providing nutrients when they need them most.

Storage and Handling

Store compost in a cool, dry place if not used immediately. Proper handling ensures the compost retains its quality and effectiveness.

Overcoming Common Composting Challenges

Using finished compost isn’t without its challenges. Identifying and overcoming these obstacles ensures we make the most of our composting efforts.

Compost Odor

A common issue with composting is an unpleasant odor, often due to improper composting techniques or using unfinished compost. Ensure the compost is fully decomposed with an earthy smell before application.

Weeds in Compost

If any weeds are present in the compost, it indicates that the compost pile didn’t reach the necessary temperature to kill weed seeds. Practice regular turning and monitoring of compost temperature.

Pests Attraction

Improperly finished compost can attract pests. Ensure compost is fully decomposed and avoid adding meat, dairy, or excessive food scraps.
