How to Choose the Best Compost for Your Flower or Vegetable Garden


We love sharing soil secrets so our extended family of gardeners, designers, contractors, urban dwellers, and soil lovers can grow healthy, hearty, and abundant gardens. With that in mind, we’ve compiled this guide to help you choose the best compost for your flower or vegetable garden, as well as the pros and cons of each product as they relate to your plant growing goals. But first, let’s discuss a little more about compost and why it is deemed the “black gold” of gardening.

Why Compost Is Considered “Black Gold”

What Exactly Is Compost?

Compost is decomposed organic matter that is rich in nutrients and often a coarse, dark brown, peat-like material. Adding compost to your soil improves the overall structure and texture as well organic matter. It increases the capacity to hold water in sandy soils and enhances drainage in heavy clay soils. It also attracts earthworms that help aerate the soil, and beneficial microbiology that helps convert materials into molecules and elements the plant can more easily absorb.

Key Nutrients for Vegetable Growth

Plants, especially vegetables, require nutrients to grow to their best and most soils need an extra boost to assure those nutrients are available. The three essential macronutrients required by plants are nitrogen, potassium, and phosphorus. Together they are vital for good stalk and leaf growth, strengthening root systems, enhancing seed production, improving blooming, helping plant immunity, acting as pest prevention, and increasing the flavor profile of edible plants. Their presence, as well as the appropriate pH of your soil, will not only help you determine how your garden grows, but also what will do well within it.

Some vegetables or flowers proliferate in a more alkaline environment, while others thrive in more acidic conditions. Cilantro, kale, and celery – for instance – need more alkaline soils with a pH of 6.0 – 7.0 to thrive. Basil, cucumber, and carrots do well within somewhat acidic soils with a pH of 5.5.-6.5. Whereas parsley, sweet potatoes, and raspberries flourish in acidic soils with a pH of 4.0-5.5.

Understanding how compost improves soil and what benefits it gives your plants will make choosing organic compost over chemically manufactured fertilizer a “no brainer.”

What Is the Best Compost for A Vegetable Garden?

The best compost for a vegetable garden depends on your specific soil and plant needs. Organic Green Waste Garden Compost is highly recommended for its richness in organic matter, making it ideal for sandy or clay soils. This OMRI-listed compost improves soil drainage and nutrient content.

Another excellent choice is the Organic Diestel Structured Compost, which stands out as one of the best compost choices for vegetable gardens. This unique compost, derived from aged cattle manure, is free from GMOs, hormones, and antibiotics, ensuring an organic and natural product. The high fungal count and diverse soil food web make it particularly beneficial for a wide range of vegetable plants.

Below is a continued breakdown of our products as they relate to your gardening needs.

Exploring the Pros and Cons of Various Types of Compost as They Relate to Your Plant Growing Goals

Actively Aerated Compost Tea

Actively aerated compost tea is a liquid concentrate containing all the beneficial microbial components that compost is famous for. The tea made at Lyngso is carefully brewed to maintain oxygen levels necessary for aerobic decomposition and is composed of microbiology that drives the soil food web in a healthy functioning soil.


  • Increases the microbial life in your soils.
  • Increases nutrient cycling so that nutrients and minerals are more available for plant uptake.

  • You can use less of it in larger surface areas, which translates to less time and less labor to apply.
  • Compost tea is portable and can be applied with a sprayer.
  • Can be used where space is a concern to bring in compost.


  • It’s a live biology and therefore is sensitive to heat, sunlight and oxygen loss.
  • Compost tea requires protection and must be used in a timely fashion.
