🌿 Top Growth Benefits of Seaweed Fertiliser
-
✅ 1. Faster Germination & Root Development
Seaweed fertiliser contains natural growth hormones such as cytokinins and auxins that help seeds germinate faster and strengthen root systems. Healthier roots mean stronger, more resilient plants. -
✅ 2. Enhanced Nutrient Uptake
It helps plants absorb vital nutrients more efficiently from the soil. This means even if your soil isn’t perfect, seaweed can help maximise nutrient delivery to your crops. -
✅ 3. Improved Plant Resistance
Plants treated with seaweed are better at resisting stress, pests, and disease. This is because seaweed contains natural compounds like alginates and betaines that support plant immunity. -
✅ 4. Increased Yield & Bloom Production
Regular application boosts flower and fruit production—ideal for vegetables, fruits, and flowering plants. Expect larger harvests and more vibrant blooms. -
✅ 5. Soil Health Booster
Seaweed acts as a soil conditioner, increasing microbial activity, improving aeration, and enhancing moisture retention—key for long-term garden productivity.
