    This year I used your Kelp Man liquid kelp in the garden and it helped me grow a 1379 pound pumpkin. We had a cool summer in eastern ontario this year, but growth stayed pretty decent for the most part despite the cold nights. I like your product and will experiment more with it in the future. It’s nice to see a Canadian company in the kelp business.

    A tale of Resurection!
    During the recent “heat dome” my geranina glooms were
    “fried”. I dead-headed, gave the plants some of (Kelpman) Coebtel
    + viola!
    Now 2+ weeks later the plants are full of healthy new buds.
    (Thank you Kelpman)

    Cheers, Pam

    Thank you Jim for your wonderful products!

    Just wanted to let you know that I just used the kelp fertilizer twice on my
    plants and the transformation is amazing, I can almost see them grow with my
    own eyes! they changed colour, turning to a much healthier green only a few
    hours after the first time.

    I felt it was so incredible with the plants that I had to acquire some
    edible kelp for my smoothies!

    Thank you for everything

    Take care
    Talk to you soon!

    Good Morning

    I am not sure if you remember me. I called you a couple of months ago from Ontario about my cedars. I purchased Kelpman as the cedars were not doing that well. We planted them in June, and it was a big challenge during the summer to keep them healthy.

    I used Kelpman 4 times and I am amazed by the results.

    Thank you for this product!

    I am attaching some pictures so you can see the results.

    My trees are doing so great since I started the KelpMan treatment in May. I am using this product once a week. Please see the difference!

    I started using KelpMan on my Christmas tree etc in my front yard as well. What a difference!

    I will start spaying them also as the spaying worked on the plans very well.

    I believe that I may need to get a pail to be able to do this.

    Purchased a small bottle of fertilizer last summer and watered my indoor plants since then. Love, Love, Love it and now the store is gone from West Vancouver when I went to buy more 🙁 Will be ordering online for sure.
