Part 2: Plant care

  1. IMPORTANT! DO NOT overwater the planting trays as Setaria prefers pretty dry soil, and warm temperatures.
  • Add 1.5 L of water to the bottom of the tray, using the empty spot. You may want to briefly tip the tray slightly away from the empty spot, to allow the water to reach all pots on the other side of the tray.
  • After watering the tray, wait about one hour and then pour off any excess water into the sink. Setaria does not like to sit in standing water.
  • The soil should feel moist, but not dry or too moist/muddy. If the soil in one pot ever feels dry, you should slowly and gently water that pot from the top as well.
  • Coordinate with your teacher to determine a watering and fertilizing schedule, but know that your schedule may need to be adjusted depending on your classroom. Plan out with your classmates when the plants will be watered and who will do this. Make sure to account for weekends and holidays. If you are not sure if your plants need water, use the soil moisture meter. Insert the probe about halfway down the pot, about halfway between the plant and the side of the pot. Setaria prefers soil that reads about 2-3 on your soil moisture meter.

2.  To fertilize, you should mix ½ tsp of Jack’s Classic Fertilizer per gallon of water (0.2 tsp per 1.5 L). Use this fertilized water to water the trays once every other week. Make sure your teacher approves your fertilizing schedule.
