anyone..

Keep in mind that a green thumb is not about having luck with plants... it's all about having the knowledge to properly care for the plants of your choosing, and applying that knowledge.

I would figure out exactly what kind of plants your topiary are, and go from there. Each type of plant has slightly different needs... with respect to light, moisture, etc... and caring for container plants will be different than caring for plants planted directly in the ground.

You can do a quick google search for information on each plant type, once you know their common names, and you should be able to locate a lot of basic information on the care, the likes and dislikes or do's and dont's, which will make caring for them easy.

Or, you can search here... for general care info on the peace lily, try the Houseplants Forum. For the topiary, I believe there's a Topiary Forum... all right here at GardenWeb.

As for the peace lily, they are generally easy plants to care for... though, they do seem to wilt quickly when not enough moisture is present... though, you also don't want to overwater... I've included a link to a great store of information on the basics of potted plant care, how water behaves in soil, etc... I think it will help you in your quest for knowledge in container gardening.

Happy Growing!
