Tree Tech Systrex Fungicide & Nutrient Micro Injection Box of 25
- Product Review (submitted on July 8, 2010):
- Found that predrilling works quite well. No containers broken since we've been doing that. Drill holes in tree; switch to larger drill bit, drill out holes in containers, put needles in, stick in tree, tap gently, hear a "pop", then push plunger till flush. Done. Works great! Really brings some trees back to life! They're full and lush now, after doing bunches this spring.
