My customers swear by these.
We have been buying kling for years. We won’t ship a tree without including a kling card.
Wier Tree Farm
We have used kling as a giveaway for more than 20 years. We give each customer 4 sheets with the recommendation that they use one a week. People return year after year and want to be sure that we still have it. You know how people are when they get something for nothing!

Last spring I broke off a small fir tree and put it in apail of water with 2 Kling cards and 90% of the needles are still on the tree. Henry White (December 2011) Cross Lake Farms
