I spend approx 2 hours per week, but that is mostly just schlepping them all to the kitchen sink or outside to water them. I am counting the days until I can just use the hose or a watering can in the greenhouse.

It seems I rarely have time for more than just watering. This weekend my in-laws were in town, and in a nice coincidence my mother-in-law wanted to see how to repot orchids. As I had SEVERAL in dire need, I took advantage of the opportunity. I think she had in mind just seeing one get repotted, but I split up 3 compots and repotted 5 more.

When I read the question I thought, what it should say is how many hours a week SHOULD I spend caring for them.
