If you’re an avid gardener or houseplant enthusiast, you’ve likely pondered the question: What’s the secret to a thriving, vibrant garden? The answer lies beneath the surface — in the soil. Specifically, organic soil enhancers are transforming how we care for our plants, and they’re turning the secret into common knowledge.

What Are Organic Soil Enhancers?

Organic soil enhancers are all-natural additives used to improve soil health. They enhance the soil’s texture, nutrient content, and overall ability to support plant growth. Unlike synthetic fertilizers, organic enhancers are made from natural materials like compost, manure, and yes, even phytoplankton.

Why Use Organic Soil Enhancers?

Here are some compelling reasons to use organic soil enhancers in your garden:

  • Nutrient Rich: They’re packed with essential nutrients like nitrogen, phosphorus, and potassium that plants need to grow. These nutrients support robust growth, vibrant colors, and high yield.
  • Eco-friendly: Organic enhancers are made from renewable resources and don’t contain harmful chemicals, making them a better choice for the environment.
  • Improves Soil Health: They improve soil structure, promoting better water retention and air circulation. This leads to healthier roots and stronger plants.
  • Encourages Beneficial Organisms: Healthy soil is teeming with life. Organic soil enhancers encourage the growth of beneficial organisms like earthworms and beneficial bacteria, which help to further improve soil health.

Incorporating Organic Soil Enhancers into Your Garden

Now that you understand the why, let’s explore the how:

Identify Your Soil Type

Understanding your soil type – sandy, silty, clay, or loamy – is essential. Each type has different needs when it comes to enhancement. The beauty of MARPHYL Organic Soil Enhancer is that it will work wonders across all soil types.

Choose the Right Enhancer

Organic soil enhancers come in many forms. Compost is great for all-around soil improvement. Manure is high in nutrients and is excellent for promoting plant growth. For a universal soil boost, consider a soil enhancer made from phytoplankton. It’s incredibly rich in nutrients and minerals that help plants thrive in any soil conditions.

Apply the Enhancer

The enhancer can be mixed into the soil at planting time, or applied to the surface of the soil around existing plants. Always follow the instructions on the product for best results. For MARPHYL Organic Soil Enhancer, mix it with water with a ratio of 1:20 and use it every other time you water your plants.


If you want a vibrant, thriving garden, understanding and enhancing your soil is key. Organic soil enhancers offer a sustainable, effective way to improve your soil’s health, and in turn, the health of your plants. The saying goes, “the secret to a green thumb is brown (soil)”, but maybe it’s time we update that to, “the secret to a green thumb is organic soil enhancers.” Your garden will thank you.
