Seasol Commercial Seaweed Concentrate 5 Litre

Liquid Seaweed Plant Conditioner in a 5 Litre Pack

Seasol Commercial is a liquid seaweed plant conditioner made from a blend of brown kelps, and this is the 5 litre pack, a good size for regular use around a home garden or smaller property. It provides a natural range of trace elements, alginates, carbohydrates and other compounds that support overall plant health. It's a conditioner and tonic rather than a fertiliser, made to work alongside your existing fertiliser program, and it's 100% soluble so it can go on as a soil drench or a foliar spray.

What It Does

Seasol helps plants establish and recover, and it's especially handy around planting and transplanting. It aids plant establishment and reduces transplant shock, stimulates root growth, enhances flowering, and boosts beneficial microbial activity in the soil. It also helps plants better tolerate stresses like heat, drought and frost. It's safe to use on all plants, including Australian natives, and can be applied at any time of year.

Application Rates

Seasol is diluted with water before use. As a general guide from Seasol, common rates per 9 litres of water are around 20ml for foliar sprays and indoor plants, 30ml for transplanting, vegetables, herbs and established gardens, 50ml for new lawns during establishment, and up to 100ml for lawn maintenance and large or stressed trees. Always follow the rates on the pack for your situation.

How to Use

Shake well, then dilute at the rate for your plants and apply to the soil around the plant, the foliage, or both. Apply in the cooler part of the day, early morning or late afternoon, for best absorption. As a general routine, apply every 2 to 4 weeks for established plants, and more often for new lawns or anything being transplanted. Use the diluted solution within 24 hours of mixing, since it works best fresh.
