OMRI Listed

Neptune's Harvest Seaweed Plant Food Liquid is an organic storehouse of over 60 naturally occurring major and minor nutrients and amino acids. The growth promoting substances in this product, naturally occurring and derived from the seaweed, enhance plant development, color and vigor. Seaweed has also been found to increase plant hardiness and resistance to adverse environmental conditions, such as early frost, extreme heat and lack of moisture. Used as a seed inoculant, seaweed fertilizer increases and accelerates germination, and enhances the rapid development of a healthy root system. Seaweed is an excellent addition to any fertilization program.

Neptune's Harvest Seaweed Plant Food Benefits

  • Soil nutrients are constantly being depleted through runoff due to overfarming, tilling, development etc...All of these nutrients eventually run into the oceans, without a return path.  Seaweed provides a way to naturally return vital soil nutrients from the ocean back to your plants, trees and turf.
  • Seaweed contains many more nutrients than Standard N-P-K fertilizers. These additional nutrients address a wider array of deficiencies.
  • Organic fertilizers stimulate beneficial microbe growth.
  • The organic nutrients in Neptune’s Harvest organic fertilizers are naturally chelated. That makes them more bioavailable for plant consumption and they will remain in the soil for a much longer period.
  • Seaweed fertilizers are commercially proven to outperform synthetic fertilizers.
  • Seaweed fertilizers increase natural sugars (brix) in plants and turf, making them healthier and less susceptible to disease and insect damage.
  • Higher sugars (brix) also make fruits and vegetables taste better and have increased market value.
  • Flowers will have more plentiful and vivid colors and blooms, and these blooms will last longer.
  • Neptune’s Harvest is an excellent natural deer repellent.

Seaweed is organic, contains micronutrients and natural growth promoting substances, and is an excellent addition to any fertilization program!

Perfect for casual wear and dressy style
Color: Dark Green, Size: Small
This sweater is soooo soft and the color is so rich. The fit of it is perfect, not too tight and not too baggy, just right and I used the size guide to pick my size. Just for reference, I am 5'3" and 130lbs, 38C bust. It's well made and washes great. I chose to hang dry mine as I typically don't put any of my sweaters in the dryer to dry, just to fluff them. I have this one in two colors, the green and the tan/beige and I would say they are both a true representative of the color shown.

Love the long sleeves!!!
Color: White, Size: Small
Love it! I'm 5' 11" tall and I purchased this according to reviews. Several people commented on the length of the sleeves. I have a hard time finding sleeves long enough if it's not " tall" sized. It was perfect for me. If this washes nice I'm going to consider purchasing more in other colors. I ordered the white and just love the long ribbed cuffs with the line of buttons. Very soft.

Great sweater for winters in the Midwest
Color: Black, Size: X-Large
Love this sweater! I went back and got another color! The fit is true to size and very comfy. The button detail on the sleeves just adds a little pizazz. The weight of the sweater is perfect for winters in the Midwest.
