Devils Ivy will grow in a wide range of light and moisture conditions, but will not tolerate permanent dry conditions though. Without a doubt it does best in a moist, humid terrarium with good light. Under these conditions it can become a bit of a monster producing large leaves and overtaking a terrarium. However, the advantage of this plant, and particularly under ideal conditions, is that it can be pruned back hard and it will come back just as vigorous as before. It can be pruned back to within a few leaf nodes of the soil, or the vine trimmed back to the required position. If the main vine is left in place and just trimmed back to the same length all the time then it will get thicker and thicker creating a fantastic jungle effect.
