Product-specific directions

Using the powder and liquid separately

Prepare and dip the cutting

Use clean shears to cut just below a node, remove the lower leaves and lightly moisten the cutting base. Dip the base into Rooting Powder #16 and tap off excess. Place the cutting in your chosen medium and keep it lightly moist, not waterlogged.

Watering and transplant care

For indoor plants, use 1 tsp (5 mL) concentrate per gallon of water every time you water. For transplanting, drench the newly planted soil area with 1 tsp (5 mL) per gallon of water once weekly until established.

Hydroponics and bare-root planting

For hydroponics or aeroponics, use 1 tsp (5 mL) concentrate per gallon when changing or adding water. For bare-root planting, presoak roots for 15 minutes in 6 tsp (30 mL) per gallon, then follow the transplanting method.

Choosing the separate softwood dip

The liquid has a separate method for softwood cuttings: dip the base in full-strength concentrate for 3–5 minutes, then place it in a starter medium. Choose the method appropriate for your plant. Follow each product’s label directions for its intended use. See the complete concentrate application guide for additional uses.
