About 8 oz (237 mL) of solution per plant, poured around the roots. 5 plants ≈ 40 oz per feeding.
About 9 days and again 5 days before planting: drench the soil with GroMax and RootMax mixed together.

- Routine. GroMax leaf spray, wait 5–7 days, RootMax soil drench, wait 5–7 days, repeat.
- How much. Drench about 8 oz (237 mL) per plant around the roots. For 5 plants, that's about 40 oz per feeding.
- Flowering. Stop leaf sprays. Use RootMax soil drenches only.
