Seaweed extract is a biostimulant — it does not feed plants directly but activates their natural growth processes. It contains cytokinins, auxins, gibberellins, and over 60 trace minerals from the ocean. Used correctly, it accelerates growth, strengthens roots, and builds stress resistance.
Dilute seaweed extract at 2–5ml per litre of water. Fill a spray bottle and apply evenly to both sides of leaves in the early morning or evening — never in direct midday sun. The stomata on the underside of leaves absorb the solution most efficiently.
Pro Tip: Spray until the leaves are moist but not dripping. Once a week during active growth gives excellent results.
Dilute at 5–10ml per litre of water. Water the soil around the base of the plant as you normally would. This method reaches the root zone directly and stimulates beneficial soil microorganisms alongside the plant itself.
Dilute at 2ml per litre of water. Soak seeds for 2–4 hours before planting. This primes the seed, improves germination rates, and gives seedlings a strong start. Particularly effective for slow-germinating seeds like tomatoes, peppers, and carrots.
When moving seedlings or mature plants, water the new location with seaweed solution (5ml per litre) just before and just after transplanting. The cytokinins in seaweed reduce transplant shock and help roots establish in new soil faster.
Note: Combine with vermicompost in the planting hole for maximum root establishment speed.
When plants show signs of heat stress, drought, or pest damage, apply seaweed as a foliar spray at 5ml per litre every 3–4 days until the plant recovers. The betaines in seaweed extract help cells retain water under stress and support rapid recovery.
