What a Bag of Organic Sea Kelp Actually Yields
Powder is the reason the numbers work. One tablespoon dissolves into 2.5 gallons of water and 8 oz makes roughly 40 gallons. The 1 lb bag covers about 2,500 sq ft at the label rate of 6.5 oz per 1,000 sq ft. Compare that to shipping a jug of liquid kelp that is mostly water. You are paying freight on the seawater instead of on the kelp.
Using Sea Kelp Fertilizer on a Schedule
Frequency splits by what you are feeding. Lawns take an application every two weeks. Flowers, shrubs, vegetables, gardens and trees run on a three to four week interval. Either goes down as a soil drench or as a foliar spray, and both routes work. What kelp brings is not headline NPK. It is the trace mineral fraction and the natural growth compounds seaweed carries. Growers reach for a sea kelp fertilizer alongside a base feed rather than instead of one. Treat it as a supplement in the program. It is allowed for certified organic production, and it stores at room temperature with no special handling. One practical note on mixing. Dissolve the powder in a small volume of warm water first and then bring it up to full strength. Dumping dry powder into a full reservoir leaves clumps that will find your emitters.
