Instructables user growerman knows you've got good intentions, but understands why all those plants in your home or office died. His seven-step guide to maintaining indoor plants will save you from your own gardening gaffes. The step titles might feel a little elementary school, but growerman gives just enough depth on sunlight, watering, soil, containers, and other necessities that you'll probably walk away a bit smarter.

A good way to accurately and efficiently find out when your plant needs more water is to keep an eye on the soil. When the soil looks dry, just stick you finger in it. If the soil is dry in the first couple centimeters, is it probably time to give the plant more water. If your finger comes up with a little water on it, your plant is probably fine.
I water my plants every Sunday, unless they need water earlier....
