I am a first year grower that grew a 1918.5 lb Minnesota State Record pumpkin using Marks Root Keeper. I believe it is one of the major factors that contributed to my success. Not only did I grow a 1918.5 lb pumpkin my first year, I grew an 11.7 lb carrot and a 5.59 lb giant tomato. I will be using Marks Root Keeper on all of my fruits and veggies next year as well. Thanks Mark for the great product. – Chris “Q Tip” Qualley
From Alaska. Our 7.15 tomato. We use Mark’s Root Keeper regularly on all of our giant and garden tomatoes as well as our squash, pumpkins and gourds. We also swear by his Beneficial Tea which we use weekly. Thank you Mark – Patrick White.
Thank you Mark Clementz for World Wide Giant Growers and your great products. My 2nd year growing melons and with the help of Root Keeper, Marks Tea, Pumpkin Power and your other products I grew a winner. I grew some nice melons and finished the year with a 290.5 lber!!!
Thanks Mark! Your Root Keeper product is fabulous! I actually grow tall sunflowers. After using Root Keeper this year, I’ve won tall sunflower contests at multiple weigh-off sites within my state. But this year I’ve never had such rapid sunflower growth. Just within 4 weeks I went from 3 foot sunflowers to some around the 13-15 foot range now. It has to be the Root Keeper.
