These will last quite a long time, Grace. It is rather astonishing really. I have had mine last for months of indoor watering under a lamp with a timer. I put mine in aluminum pans to protect against my occasional overwatering:) As long as you don’t overwater too often, you will be fine. I usually start my seeds indoors about now, and some of them don’t go out into the garden until May. If the plant is the type to get too big for the cup in that amount of time, I make a larger cup, with a larger can. I do find the paper pots like more frequent watering than a plastic container because the water evaporates more easily with the paper. Any paper will do, black and white newspaper, leftover printer paper. You should make some for the kitties to play with. They will love them! Although that might make them more likely to get into the ones you don’t want them touching! Maybe not, haha!

Sorry for all the questions! I have two cats and don’t want them getting the soil all over the tiny flat.

This is my way of having my personal spring indoors!

Well color me happy! Such a nice comment. I love gardening. These paper pots are so convenient.
