There's a lot less humidity in the winter. Trying spritzing them with a water bottle. Use and old clean Windex bottle or a $ store should have one.
Reply:Sometimes they get taily and need to be cut back a little, in order to grow.
Reply:Are they getting enough sunlight in these winter months? Miracle Gro has these house plant fertilizer spikes, that always seems to cheer my plants up.
