Bonita Ash Slow to Leaf Out: Normal or Borers?

Young Bonita ash in far West Texas desert hasn't budded while others have; trunk has long splits and odd spots. Owner suspects borers.

Normal Timing

Ash, pecan, hickory leaf out later than other hardwoods. Scratch twig bark—green and flexible = alive.

Borers Prevention

Apply Bayer Advanced Tree & Shrub Insect Control (imidacloprid) as soil drench—systemic, season-long protection against borers, aphids, scale, caterpillars.
