FAQ
Questions arborists ask
What is Stemix Plus?
Stemix Plus is a nutrient from Mauget with Chelated NPK + Micronutrients as the active ingredient. It is applied by trunk injection.
What is the Stemix Plus rate per inch of DBH?
The label sets the dose by DBH band, not a flat rate per inch. A 8 inch tree takes 24 to 30 mL low, 24 to 30 mL medium, 24 to 30 mL high (label band 8 to 10 in). The PHC Rx calculator reads the band for the tree in front of you and sets the number of injection sites.
How often can Stemix Plus be applied?
Label frequency: Annual or as needed for deficiency symptoms. Minimum retreatment interval 365 days. Expected protection about 12 months. Time to effect about 21 days.
Where do these numbers come from?
The PHC Rx product catalog, built from the Stemix Plus label linked above, and synced to this page from the app. The label is the legal document; if the two disagree, the label wins and the catalog gets fixed.
