Keeping it Going
Cut back hard in the spring - new growth regenerates from woody stems - this will create a more compact plant
In cold weather, lemon verbena needs to be brought inside. It will drop its leaves when stressed with cold (don't throw the plant away; the leaves will grow back.)
It is a heavy feeder. Give it a well-balanced water soluble fertilizer 1x month
Keep soil moist, but not soggy

Poorly drained soil - especially in the winter (produces root rot)
