Seaweed fertilizers are naturally occurring, plant based solutions that have become increasingly popular among gardeners and lawn care professionals who want to create thick, beautiful and healthy green lawns. For centuries, seaweed based nutrition from the ocean has been used by farmers along coastal areas to enhance the strength of grass by working with its roots, without the use of harsh chemicals.
Seaweed extract contains trace minerals, natural hormones that encourage growth, and bioactive compounds which improve soil quality while enhancing root development and the ability of grass/ turf to be able to tolerate stress. Seaweed extract allows the lawn to better absorb nutrients, encourages the growth of beneficial microorganisms in the soil and promotes steady and balanced growth, resulting in more green grass with higher density and enhanced coloration.
One of the major benefits of liquid seaweed extracts is they can be absorbed quickly and easily. When applied to lawns, they penetrate quickly both into the soil and into the tissue (leaves and stems) of the grass, enabling grass to reduce the effects of heat, drought, cutting and foot traffic. As such, liquid seaweed extracts are ideal for maintaining grass regularly and aiding in recovery after difficult weather events.
The use of seaweed based plant nutrition will provide many benefits to your lawn, from improving your soil structure to promoting consistent, even growth. Each application of seaweed based plant nutrition will provide your lawn with a little bit of nourishment over time; so not only does liquid seaweed fertilizer provide great results, it is also the secret to the health and appearance of your grass.
Understanding Seaweed Fertilizer: What Makes It Unique?
Fertilizer made from seaweed is unique due to how it complements rather than contradicts nature; it is the most effective product available for lawn care. As a nutrient-rich resource derived from oceanic algae, seaweed has been a valued agricultural product along coastal regions for centuries and is now widely regarded as the best way to achieve green, vibrant, and sustainable lawns. While conventional fertilizers do produce immediate results for rapid growth, the ingredients in seaweed fertilizer help achieve long-term benefits by promoting healthy soils, strong root systems, and drought-tolerant grass ultimately creating thicker, greener lawns.
The nutrient content of seaweed fertilizers contains natural plant growth hormones, minerals in trace amounts, and the ability to stimulate the beneficial bacteria and fungi that are present in soils, which power the lifecycle of a grass plant from inception through to its final stages. This unique combination creates uniform, fast-growing grass, which retains its color without risking grass damage or death.
What Is Seaweed Fertilizer for Lawn Care?
Seaweed fertilizer is a natural plant tonic that comes from seaweed (usually kelp) that can be processed in many different ways to produce a product that provides nourishment to your lawn and its underlying soil at the biological level.
The following key characteristics of seaweed fertilizers describe some of the reasons why they are so beneficial to lawns:
