Hi,

It really depends on your house conditions, like lighting, humidity, etc. But I water mine (which are almost in full sun) about every 3 weeks. I wait til the soil is very dry. They hold lots of water in their succulent leaves. If kept outside in summer it would need a little more, less in winter.

Probably once a month and maybe skip a couple months in winter.

Only slightly more than you would water a cactus. Stick your finger in the dirt. If it is dry 1" down water, else wait.

I'm in the same boat as you. This sans watering thing can get complicated. There's just so much information out there.

My mother has the really common sans you see in stores all the time. It is in a glazed, six inch pot about a foot away from a south window. She says she waters hers about every 7 or 14 days. She doesn't keep track strictly. Just when it's dry. It's been growing like crazy over the past two years.

I have some sans too. Four types. They have been doing pretty well for me all spring. I have decided to let the soil dry all the way through then wait a few more days, and then water. Right now they are in 3 - 4 inch pots. I have been watering probably every 9 or 10 days. That's only because they're growing right now though. When they go dormant, or stop growing for a time, I will wait until the leaves become slightly wilty or bendy.

Perhaps one of the differences is container size and plant size.

With my snake plant it is in a 12" container and fills it up. There is a lot of water holding capacity in that sized container. A smaller plant in a smaller container would likely go dry faster just from evaporation.

I think potting mix also has an effect. Mine is in a peat based potting mix I haven't changed in years. Naturally it's quite broken down and thus holds lots of water. A more coarse or even fresher mix would probably need water more often. I probably should repot to get some fresh mix, but why fix what ain't broken?

chris, the only REALLY correct answer to your question is: " Water your plants when they need it." Each of the above answers indicate that these people have a clear understanding about this plant and they have each adjusted the watering according to their own particular situation. The common thread, however, is that this plant must be allowed to dry out in between waterings. Then really drench it.

Justa, can you imagine what your snake plant will do when (IF) you decide to repot it? I had the same situation with one of mine, by the way. Hadn't done anything to it for AGES. A couple of years ago I finally transplanted it to a mostly Turface medium. HOLY CRAP! What a growth surge. ;-)
