Its time to start feeding….

As the weather starts to improve and the sun shines, the days are longer, our houseplants can breath a sigh of relief that they may just start to receive the amount of light needed to flourish. Its been a dark old winter and growth has slowed right down.

Spring to Autumn is the time to replenish those lost nutrients in the soil while the plant is in its prime growing time. Generally specialist houseplant soils come with added nutrients, (lasting about 6 months or so) after this its important to replace nutrients through feeding or repotting in fresh soil.

I choose to organically feed with seaweed plant food and am a proud stockist of Cornwall based brand Aqua Culture. Co founded by Dan and Jack, Aqua Culture’s mission is to transform waste seaweed into a powerful, natural fertiliser that feeds plants, enriches soil, and helps regenerate our environment.  Every bottle and pouch they make starts with cast seaweed, (collected responsibly to avoid harming coastal habitats) Through gentle processing, they create pure plant nutrition with nothing artificial added.

What Makes Seaweed Fertiliser Special?

• Packed with nutrients: Seaweed naturally contains potassium, magnesium, nitrogen, and trace elements that support growth.

• Boosts resilience: It helps plants withstand drought, frost, pests, and disease by strengthening root systems.

• Promotes vitality: Natural plant hormones like cytokinins and auxins encourage strong root and shoot development.

• Eco-friendly: Unlike mined or manufactured fertilisers, seaweed requires no extraction - we only use what washes ashore, classed as ‘waste’.

  10 Benefits of Organic Seaweed Fertiliser for Healthy, Happy Plants

1. Stimulates Strong Root GrowthSeaweed is rich in natural plant hormones like auxins and cytokinins, which encourage root development. Stronger roots mean more efficient nutrient uptake, increased drought resistance and faster recovery after repotting.

2. Promotes Balanced, Steady Growth Unlike synthetic fertiliser’s that push plants into fast, unnatural growth, seaweed offers gentle, balanced nutrition. With over 60 trace minerals, amino acids and vitamins, it supports full-bodied foliage and steady upward growth - without the risk of overfeeding.

3. Boosts Flowering and Fruiting If you’re feeding plants that flower or fruit - think chillis, strawberries, tomatoes or roses — seaweed is your best friend. It supports cell division and bud formation, helping your plants produce more blossoms and tastier harvests.

4. Builds Soil Life and Microbial Health Healthy plants start with healthy soil. Seaweed feed improves soil structure and encourages the microbial activity that helps unlock nutrients in the root zone. Over time, this creates more fertile, aerated, and moisture-retaining soil.

5. Helps Plants Resist Stress and Disease Seaweed naturally contains antioxidants and compounds that strengthen a plant’s immune system. It helps plants bounce back from drought, cold snaps, pest attacks or root damage.

6. Safe for Pets, People, and Pollinators Our seaweed fertiliser is 100% organic and made without synthetic chemicals or preservatives. It’s gentle on your home, safe for indoor use, and kind to the insects and creatures that keep our ecosystems alive.

7. Suitable for Regular, Year-Round Use Because it’s low in salts and naturally balanced, seaweed fertiliser can be used every week during the growing season - and monthly in winter. It won’t scorch roots or cause nutrient lock like harsh chemical feeds can.

8. Improves Leaf Shine and Colour Struggling with dull, tired leaves? Seaweed can help. The trace elements and vitamins support chlorophyll production, leading to deeper green tones and a natural, healthy shine.

9. Works as a Root Soak or Foliar Spray Use it your way. Dilute seaweed fertiliser in water and pour into the soil, or spray it directly onto leaves for faster uptake. As a foliar spray, it’s absorbed directly through the stomata - perfect for reviving tired houseplants or supporting stressed roots.

10. A Fully Circular, Sustainable Choice  At AquaCulture, they make their plant feed using waste seaweed from the Cornish coast - a by-product of local activity, turned into a powerful resource. It's produced using solar power and natural spring water, bottled in recyclable glass, and shipped with care from our farm in Ruthvoes.

Every bottle supports the soil, the ocean, and the future of regenerative growing.
