Fill the GrowBox with your favorite potting soil (I use this SECRET MIX) and lay a row of fertilizer down the middle of the planter on top of the soil.
2. Cut holes for your plants (following the directions for planting by numbers included with the container) and lay the planting patch over the top of the soil and fertilizer.
3. Plant your plants and add water. Keep the water reservoir filled with water throughout the growing season.
