This is a newbie question but, well, I'm a newbie to gardening so I guess it's natural ... anyway last fall I bought two small sweet lavender plants for my window box. I live in an apartment so that's the best I can do for now ... anyway, not knowing what to do I put those two small plants in a 20" box with dreams of them flurishing and filling it. Yeah. Hasn't happened. They've just grown very "leggy" (for lack of a better word) - brown and leafless the first few inches, loooong branches coming out at odd angles above that. They look like neglected weeds. Or looked - today I got tired of them looking so sad and trimmed them way down with my little pruning scissors. Now what? How can I encourage them to grow fuller rather than just long? Any tips? Oh, and along with trimming I added another plant (not a lavender - unfortunately I don't remember what type it is. Bad me) to the box so it doesn't look so bare. So anyway, any tips?
