Nurturing soil for sustainable flowers: From a healthy patch of soil to a bouquet in your hands

Wednesday 23 July 2025

At the Marginpar flower farms, sustainability starts in the soil. Healthy soil creates thriving ecosystems, resilient plants, and ultimately, stunning flowers. It’s their way of ensuring that future generations can enjoy nature’s beauty, one bouquet at a time.

There was a time when farming relied on synthetic chemicals to protect crops. Quick fixes, yes, but ones that came at a cost, impacting soil quality over time. At Marginpar, they’ve embraced a nature-first approach, working with the earth rather than against it.

One key strategy? Enhancing biodiversity. By using cover crops and leaving plenty of space to rotate crops, they create natural habitats for beneficial insects and soil microorganisms to keep their soil vibrant and full of life. This reduces the need for chemical interventions.

Matching crops to soil types may sound basic, but it’s often overlooked. They moved from a product-driven mindset to one led by sustainability.

‘’Our farms are buzzing with life, thanks to carefully chosen plant species that enrich the soil and ultimately strengthen our flowers.’’

The power of rotation and cover crops

“Rotation and cover cropping are fundamental to maintaining soil vitality,” they explain at Marginpar. “When you plant the same crop repeatedly, you deplete the soil and invite pests. By rotating crops and planting cover crops the balance is restored.”

Cover crops do more than just fill space. They:

  • Enhance soil structure,

  • Provide habitats for pollinators, and

  • Reduce erosion

Organic matter and worm tea

What’s the secret to vibrant soil? Organic matter. On every Marginpar farm, plant materials are recycled and composted to enrich the earth. But that’s not all, they also introduced vermiculture units.

These units house worms that create “worm tea” or nicknamed “jungle juice”. Packed with beneficial bacteria and nutrients, it gives the soil a boost while cutting down on the need for synthetic fertilisers.

Why does this matter? Healthy soil means resilient flowers: that look just as stunning in a vase as they do in the fields.

More organic matter means more water retention

At Marginpar they believe in the principle of “measure, monitor, and manage”. Over the years, they increased the organic matter in their soils: a win for the environment and the flowers.

Marginpar shares an incredible insight:

“Each 1% rise in organic matter helps soil retain 150,000L more water/ha. Since 2018, our Kenyan farms improved levels by 25%: resulting in an extra 22 million litres of water stored and greater drought resilience.”

A journey towards greater sustainability

Sustainability isn’t a destination, it’s a journey. Each season brings new challenges and opportunities to refine practices. For Marginpar, it’s about contributing to a healthier planet while delivering flowers that tell a story of care and connection.
