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!

Extremely diappointing
Style: 15" (2 x 2Ah)
I purchased a Greenworks Impact Wrench for my son. I was so so impressed with it that I purchased one for myself & decided to try their 2x24V 15" Cordless String Trimmer. Unfortunately just because a company makes one excellent tool doesn't mean that all their tools are good. The first problem I had with the trimmer was that it didn't come with the batteries or charger in the ad. It was supposed to have 4.0Ah batteries but came with 2.0Ah. In addition, more often than not, the manual didn't agree with actual parts & features. The trimmer requires two 24V batteries to operate. It can't be used with one battery even though it has a "low power" setting. On full power the trimmer had adequate power for most weeds but is no where near as powerful as a gas trimmer. The batteries only lasted about 20 minutes (this trimmer does not have a brushless motor). The 2 line feed head is not designed for easy reloading. In fact, it is the worst design I've ever owned. I've decided to return it & try one of their 2x24V brushless motor trimmers which should provide more power & has 4.0Ah batteries but costs significantly more.

CUSTOMER SERVICE IS TRASH - edited
Style: 15" (2 x 2Ah)
I bought this product and it arrived with one battery that doesn't charge out of the two. Without 2 batteries, it won't work at all. Attempted to contact Greenworks with the number Amazon provided. They were closed on the weekends. Called Monday and the message stated that customer support closed early. Attempted using the Chat option for help. It states the model number STE304, doesn't exist, so I couldn't proceed. Called on Tuesday. I have been on hold for over an hour and still nothing. Will update. After about an hour and a half on hold (yes, the offer the option of leaving a call back number, which I didn't use as I had to work from home to access customer service when they were open. Also, they needed me to try out stuff with the batteries and give them serial numbers, etc.) The lady I spoke to spoke English and appeared to be US based. Eventually, after doing the "did you restart it" version of troubleshooting, it was indeed determined my battery didn't work and they offered to ship me a new one at no cost. I then had to dispose of my non-working battery in the proper manner, and our yearly toxic garbage pick up coincided with this, thankfully. It took time out of my work schedule to get this resolved, but the lady I spoke to was great and I did get my battery about a week or so later, which I did appreciate. Customer service needs better access esp since you have to have the physical batteries and charger to get this resolved, which you may not be able to do while working. Maybe they can't find people to work as that seems to be an issue everywhere. The weed eater works fine. Updated from one star to three based on resolving issues and a dead battery upon arrival, rather than the actual equipment working.

Edged entire corner lot with a sidewalk on one charge of the batteries.
Style: 2 x 2.0Ah
Excellent. A bit heavier than my echo gas weed trimmer for reference. Fair balance but it is a bit of a workout. The good thing is I can edge a 10k sq ft corner lot in about 1/3 the time. On the corner, I have both sides of the sidewalk plus the curb side to do. I've owned gas edgers before also. This comes in comparable to the price I paid for one of those 20 years ago so I would also say a good if not very good value for the buck. It was not an initial edging but 1st maintenance for the year and rather overgrown. Didn't even use one full charge on the edger.

Amazing!!! Works great
Size: 9 inches
Works really well. Cit through my Saint Augustine grass like a breeze and it is super thick. Very happy with purchase. Battery has good life, charged it for a full 24hrs before use and it last a long time. They send 2 blades and the battery with charger which is a huge plus because everything else I looked at you had to purchase those separately and it was just as much as the edger. This is a great deal and worth the money. Highly recommend 👌
