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!

Comfort and Appearance
Size: 9, Color: Black
The shoes were as advertised. Marc Joseph (I hav 4 other pairs) are the perfect shoes for me with my physical needs. Additionally they are exceptionally comfortable and attractive. This pair I returned because they weren’t quite the right fit for me. They are, like my other Marc Joseph shoes, very well made and very attractive.

Ok in a pinch. Can get better shoes for the price. Wide aren’t wide
Size: 9 Wide, Color: Black/Black
These were ok comfortable. Would have preferred at the price point to be a little more comfortable. For being a wide size, the shoe was rather tight on my feet. Quality is ok. It passed for the wedding. Would probably have taken more time to pick something different if I had the ability to. This was a last minute purchase.
