The Wedgle Direct-Inject System was introduced in 1993 and remains the first and only no-drill tree trunk-injection system on the market. New injection tips were pioneered for conifer direct-inject treatments in 2006. Injection of palms began in 2011. Why drill trees to “care” for them when you can effectively control pests and prevent disease without drilling? Compare the Wedgle Direct-Inject System to spraying, soil drenching, or any other trunk injection method. You won’t find a more effective, efficient way to treat trees.
