Plant Growth Regulators - Combination Planters

Combinations of plant species that require different PGR treatments can be a challenge to manage. Pre-planting the sweet potato plugs (in this photo) by soaking the plug flat in root-active PGRs (e.g. Bonzi, Sumagic, or Topflor) prior to planting will control vigor on the individually treated plants for many weeks without affecting the other plants in the combination.
