Wedgle Direct-Inject Tree Treatment System simplifies the tree care process for you. It requires no power, no drills and no pumps. Everything you need is included in one carry case. But you need to take care of it every day and, most importantly, at the end of season so you are ready for the next one. You can clean it in a bucket of water or with the garden hose adapter but it needs to be done to keep from clogging or corroding. Just as you can treat almost any tree in five minutes or less, cleaning the unit takes minutes too. For more information, click here.
