The Propagation Formula

The Propagation Formula houseplant fertilizer mixing recipe

For cuttings and new propagations in soil, perlite or LECA.

Ingredients

Ingredient Amount
Root Builder 2 scoops
Repot Rescue 1 scoop
Water 1 gallon

Add all scoops to 1 gallon of water and stir until dissolved.

How much to use per pot

  • Small pot (4 to 6 in): 1/4 of the recipe (about 1 cup)
  • Medium pot (8 to 10 in): 1/2 of the recipe (about 2 cups)
  • Large pot (12 in and up): the full recipe (1 gallon)

Frequency: Every 2 weeks until roots are established.

Why it works

Root Builder supports root initiation, and Repot Rescue supports the cutting's stress recovery while roots develop. There is no nitrogen in this mix because cuttings need root establishment, not top growth.
