Fittonia globe terrarium (6in Ht)

Cut the Fittonia stems 8-10 cm, selecting stems with 4 to 5 leaves. Put some well-drained and nutrient-rich soil into the two plastic cups. The reason to use clear plastic cups is - to allow you to see the root development clearly. Place the cut-stems about an inch down into the soil, and then pack the soil around the base of the stem. Water the cuttings, place them into a plastic Ziploc bag, and then spray them with water. Blow air into the bag to expand it so that the plants have room to grow. Once the air has been blown into the bags. Close the bags and place them below the fluorescent lighting or in indirect bright light.

Check the moisture in the soil before watering it, Poke your finger into the soil, if dry then apply water. Do not overwater the plant.
