Description
MARPHYL® Organic Soil Enhancer is harvested when the nutrients have settled at the bottom of the tanks. This concentrated liquid contains an abundance of nutrients, vitamins and minerals from the marine phytoplankton, and it’s recommended for use only on household plants, urban/veggies gardens, lawns, golf courses and greenhouses.
Plants rely on potassium to facilitate the circulation of nutrients and on nitrogen as the essential element in photosynthesis, while the roots need phosphorus to thrive. MARPHYL® Organic Soil Enhancer is high in potassium, nitrogen, and phosphorus, and also contains trace amounts of other nutrients, such as calcium and magnesium for optimum plant health and growth.
MARPHYL Organic Soil Enhancer is very easy to use. Click HERE for the detailed instructions.

I bought this fertilizer mid summer for my outdoor pot plants, indoor plants, and vegetables as I wanted an organic fertilizer and was having trouble fining something. I had tried other products which were labeled organic but I am uncertain about that now as they had been discontinued. I particularly liked the fact that it is a local product, developed by a local company.
During the first week or two there was no apparent effect, and then away everything went – I mean everything! Vegetable garden, pot plants (indoor and out), gardenia, basil, herbs, lavender, ivy, apple tree, cornflowers, tomatoes, beans, etc…
All really healthy and plenty of new growth, which seems to be sustained. I am very impressed and ordering more even though it is fall. I am also ordering the human supplement – if this it what it does to my plants, I want to see what it does for my body 🙂
MARPHYL Marine Phytoplankton –
Hi Sue. We are so happy to hear that all your plants are thriving with our Soil Enhancer! And thank you so much for your support.
Keep us posted about how you like the Natural Supplement. We take it daily ourselves 🙂
Drew Widdicombe –
Love this stuff- I use it mainly on my indoor tropical plants and my raspberry garden. In two seasons it has become a necessary part of my gardening toolkit.
MARPHYL Marine Phytoplankton –
Hi Drew,
Thank you so much for your feedback, we are very happy to hear that!
Frank –
How much is 1 portion?
MARPHYL Marine Phytoplankton –
Hi!
If you need X amount of water to water your plants, you need to divide it by 20 and you will known how much Soil Enhancer to add.
For example, for 1L of water, you need 1L/20=50ml of Soil Enhancer.
For 2L of water, you need 2L/20=100 ml of Soil Enhancer.
Hope that helps.

My dog loves this stuff – when I water the plants he follows along licking what he can
Is there any harm to him? Is it checked for contaminants? I get it’s for the plants but is it ok for my dog too?
MARPHYL Marine Phytoplankton –
Hi,
Indeed, it is safe for your dog. The only ingredient that there is is decomposed phytoplankton.
And we do thorough checks for every bath, please see here for more information https://marphyl.com/quality-control-is-our-1-priority/

I bought an old house with tired front and back yards. I had everything pulled up, new sod put in and planted new perennials around the grass. It has been two years now and the plants are still looking like toddlers. I spread the soil enhancer around a week ago and now am noticing increased growth just this week, as well as improving amount/quality of flowers. Even the orchids in the house are sprouting new shoots for flowers! After the first go at it, the container (1 gallon) is now half full. I plan to spread this around again this week and hopefully see these babies of mine grow into beautiful lush plants. Question though, would it be harmful if i gave my babies a drink again this weekend? How often should I fertilize with this?
MARPHYL Marine Phytoplankton –
Hi,
It sounds like you have a fascinating project on your hands. And we are happy to hear that your yard and your orchids are loving out Soil Enhancer!
We recommend adding the Soil Enhancer to the water every other watering, otherwise you might over-fertilise the plants.
Please let us know if you have any other questions, we are always happy to help.

My name is Aron and I live in the Okanagan, we have many fruit trees, edible berries, a hobby garden, countless indoor plants. I came across your soil enhancer through Amazon…and have bought several 4L bottles. I have always had leaf curl and dull looking leaves on my cherry and various fruit trees. Within weeks of 2x a week application I saw a transformation with the foliage. My strawberry garden is a foot high, veggie growth is phenomenal. I even applied to my thornless blackberry bush and it has exploded. I use a weak dilution on all my watering inside and out, I even mist many of our indoor plants with this diluted as well. I’m kinda addicted, probably use too much…but love the results!
MARPHYL Marine Phytoplankton –
Hi Aron,
Wow, thank you so much for your feedback! It means a lot to us. We are delighted to hear how well your plants are doing. Fell free to tag us @marphylco if you are on Instagram, we would love to see the progress 🙂
So Ma –
What ratio should be used as a foliar spray for seedlings?
Thank you
MARPHYL Marine Phytoplankton –
Hi, we recommend the same ratio as for watering – 1:20. 1 part Soil Enhancer to 20 parts water.
