How would you go about caring for a lemon grass plant in the house when the plant it getting too tall? I have two lemon plants and I have repotted them to a larger pot. They are growing great but they are getting too tall. Can they be cut back wilthout damaging the plants? Also, right now the plants are on the patio but we live int the mountains of NC. We will have to bring them inside soon. Is the care inside different than outside?

Yes, you can cut them back. They respond well to being trimmed.
Indoors, they will need high light, as much light as you can give it. Water only when the top of the soil is dry to the touch. Even then, you should expect that keeping it over winter is more of a way to make it survive, rather than thrive. It will begin to look rather ragged by spring, but will bounce back quickly when placed back outside.
For this reason, many people choose to put the plant in dormancy for the winter. This is simply putting it in a cool, dark, dry place for the winter and watering once a month until you can place it outside for the spring and resume normal care.
