Juicy, sweet, fresh from the garden tomatoes (Lycopersicon esculentum) don’t just grow on their own. It takes ample water, good soil, plenty of sunshine and an adequate amount of nutrients to reap such rewards. Neptune's Harvest Organic Fish/Seaweed Blend Fertilizer is a fertilizer that combines fish hydrolysate and seaweed that result in a 2-3-1 nitrogen, phosphorus, potassium ratio. Tomatoes benefit from a good amount of fertilizer mixed into the soil before planting. Because this product has a low concentration of nutrients, consistent with an organic product, and is a water-soluble fertilizer, it doesn't work well for amending soils. It is a better choice as a fertilizer to apply starting when the plants set fruit.
Shake Neptune’s Harvest well before opening. Measure 1/8 cup of the fertilizer and mix it with 1 gallon of water. Shake or stir the mixture. Make only what you need because the mixture does not store well.
Pour the mixture around each tomato plant, covering an area that is about 2 or 3 inches wider than the plant’s canopy to ensure the fertilizer covers the root area. Use enough of the mixture to water the area with 1 inch of water.
Repeat fertilizer applications in the same manner every two or three weeks until the plant dies back in fall.
