2026 Adam recommends:

  • Vigaro Organic Plant food 5-5-5 (once a month)

  • Vigaro Tree, Shrub, Evergreen 16-4-8 (once every 3 months)

  • Ironite 0-0-0 (once in spring & fall )

  • Liquid (e.g. kelp) once a week to once a month

Adam Toth recommends these together on both conifers and most deciduous trees.

Also using liquid cal-mag + fox farms big bloom every 10-15 days during growing season, along with those granular ones.

Adam did not recommend those liquid ones. I heard to do on a pod with Andrew Robson.

IIRC he likes to rotate fertilizers, mostly organic. Chemical if plant is in growing phase instead of refining
