I don't have spider plants, but those who do pretty would want to know what kind of soil you use before giving you advice. That's because many folks around here use growing media made of large particles that drain very quickly and stay aerated even right after watering, which calls for very different watering habits than the more common fine grained peat based potting soil. Hopefully this bump will attract more attention.

Thanks. Hoping for others to respond, too.

I let mine get dry before watering,not on purpose but because sometimes I forget.

They seem happy though so I when I do check them and if they are damp I wait.

I did kill one by paying too much attention to it

that is what I am practicing doing now with mine. I got it second hand so I am not sure what the soil content is. It is in a very sunny window, getting western light. I hope that is OK.

I used a regular potting soil for mine and water a couple times per week in the spring/summer and less in the winter. I keep them all in a pretty sun-lit room. They're a great starter plant - pretty difficult to kill, even when a little neglected.

how big is the pot?

Medium sized pot -- probably would hold 4-5 cups of water if empty. It has been at least 3 weeks almost since watered and soil does not look dry. Leaves look fine. I guess a sign of needing water would be if leaf tips turn brown? Is that right?

If a plant in a pot that holds 4-5 cups of medium can go >3 weeks between waterings, there is certainty in reasoning you are leaving a lot of unrealized potential lying on the table. Over-watering and extended periods of soil saturation result in the same drought response caused by a moisture deficiency.

Three weeks is a long, long time. Since its so easy to get the plantlets or whatever they're called to propagate, why not try a different soil mix... maybe two?
