Mother in Law’s tongue prefers shaded areas and well drained soil.  The plant can tolerate a variety of soils but is native to tropical areas so prefers warmer weather.   It makes an excellent indoor plant, so you can grow one in cooler areas,  it requires little light and just a little bit of water.

A mature plant can reach up to 1.5 meter high and will spread through a creeping rhizome, so provide enough space if planted outdoors.  For indoor planting you can use any medium to large pot, depending how big you want it to get.

These plants really do not need allot of water, if planted outside and it is warm with no rain you can water every two to three weeks, during the winter months you can water ever other month to every two months.  The roots will rot if over watered.
