When planting new trees, shrubs, or flowers, you can incorporate finished compost into the planting holes. Mix some compost with the backfill soil before placing the plant in the hole. This provides an immediate nutrient boost to young plants and helps establish strong root systems.

4. Using Finished Compost in Potting Mixes

4.1 Proportion of compost in potting mix

When creating potting mixes, a general guideline is to use 20-30% finished compost by volume. This proportion provides a good balance of organic matter and nutrients without overloading the plants with excessive nutrients. However, this ratio can be adjusted based on the specific needs of the plants you are growing.

4.2 Benefits of using compost in potting mix

Incorporating finished compost into potting mixes improves soil structure, enhances moisture retention, and increases nutrient availability. The organic matter in compost helps create a well-draining yet moisture-retentive medium, which is essential for potted plants to thrive. Compost also introduces a diverse microbial community that contributes to overall soil health and plant vigor.

4.3 Homemade compost vs. commercial compost

Using homemade compost allows you to control the quality and ingredients, ensuring that no harmful chemicals or pesticides are present. However, homemade compost may not offer consistent nutrient levels and may take longer to produce. Commercial compost, on the other hand, is convenient and offers a standardized nutrient profile. Look for reputable brands that prioritize organic and sustainable practices.

5. Applying Finished Compost to Lawns

5.1 Topdressing for lawns

Topdressing lawns with finished compost involves spreading a thin layer of compost over the grass. This helps improve the soil’s structure, enhance nutrient content, and promote healthier, greener lawns. Choose compost with fine particles to ensure easy application and even distribution.

5.2 Overseeding with compost

Overseeding with compost involves spreading a mix of grass seed and finished compost over bald patches or thin areas in the lawn. The compost provides an ideal environment for seed germination, increases moisture retention, and offers initial nutrients for young grass seedlings. This method helps promote a lush, dense lawn with improved resilience.

5.3 Spot treatment for bare patches

For smaller bare patches in lawns, you can apply finished compost directly to the affected area. Spread a thin layer of compost and gently rake it into the soil. This helps improve soil structure, provides essential nutrients, and encourages healthy grass growth. Regular watering will aid in the establishment of new grass in the treated area.

6. Compost Tea

6.1 What is compost tea?

Compost tea is a liquid fertilizer made by steeping finished compost in water. The process allows beneficial microorganisms and nutrients to be extracted from the compost, resulting in a nutrient-rich liquid that can be sprayed directly onto plants. Compost tea acts as a natural plant booster, providing additional nutrition while improving soil health.
