Seaweed in cultivation: The secret of vitality straight from the ocean 🌊🌿

In recent years, seaweed-based products have become increasingly popular among growers – and it’s no wonder. These natural “superfoods” for plants are packed with bioactive compounds that help with growth, increase resistance, and support better harvests.
🧬 What does seaweed contain?
Seaweed, especially brown ones like Ascophyllum nodosum, is rich in:
- Natural hormones (auxins, cytokinins) that promote growth
- Vitamins B, C and E
- Trace elements such as zinc, manganese, iron or boron
- Amino acids and enzymes to improve cellular activity
All this in a natural form that is easily absorbed by plants.
🌿 How do they help plants?
Using seaweed brings a number of benefits:
- Improves rooting – ideal for seedlings and cuttings
- Reduces stress – helps with transplanting, drought or temperature fluctuations
- Stimulates flowering and fruiting – higher yield and better taste
- They increase plant defenses – plants are less susceptible to diseases
🌱 When and how to use them?
Seaweeds like Seaweed Organic can be used throughout the entire vegetative phase – from germination to the beginning of flowering. They are applied either in a nutrient solution, directly to the soil, or as a foliar spray. They also work great in combination with other fertilizers – they enhance their effect without overwhelming them.
Here is a simple graphic showing when and how to use seaweed intensively during each stage of plant growth:
- ✅ Greatest effect : during germination, rooting and vegetative growth
- ⚠️ Slightly during the onset of flowering
- ❌ Not recommended during peak flowering and fruiting stages
Summary:
✅ The natural way to healthy and strong plants
✅ Works in soil, hydroponics and by spraying
✅ Suitable for all types of plants - from herbs to tomatoes
