A Complete Seaweed Fertiliser Guide

Are Seaweed Fertilisers Good for All Plants?

All types of plants can benefit from seaweed fertilisers. Containing complex carbs and vital minerals, seaweed extract delivers every plant with the valuable nutrients needed to grow and thrive.

In fact, seaweed fertilisers have the broadest range of benefits to plants beyond plant nutrition. They also promote bacterial activity in soil mediums. Known to improve root nutrient intake. Along with having the ability to improve resistance to disease, pests and abiotic plant stress.

Key Term: Abiotic Stress – The effect of non-living factors on living organisms within an environment. Examples of abiotic stress in plants include hot/cold weather, soil salinity, drought and heavy metals.

Where and How to Use Liquid Seaweed Fertiliser

Seaweed fertilisers can be used all around your garden. Whether that’s on your lawn, fruit and vegetable patch or on flowers. Of course, your results will vary depending on where you use the treatment.

For example, you will find that your lawn is lush and evenly green in comparison to an untreated lawn. While your fruit and vegetable garden will benefit from greater and healthier harvests.

However, the most important thing to understand is how to use liquid seaweed fertilisers, especially liquid forms, because this will greatly determine the results of the treatment. Liquid seaweed fertilisers are strong; therefore, dilution is essential to avoid burning seeds and roots.

Always check the instructions for dilution rates. Not all plants are the same, so it’s not one size fits all when it comes to feeding them.

When to Use Seaweed Fertiliser?

Apply these fertilisers when plants are actively growing. I.e. in the midst of the gardening season. In the UK, this is generally between March and September.

However, Seafeed Xtra contains seaweed that has been extracted at a specific time and state. This allows the seaweed to transfer stress resisting nutrients onto other plants. So, those of you who are growing in Autumn and Winter can benefit from treating overwintering plants with a year-round feed.
