Answer: Begin by pruning off the faded flowers and some of the stem to open the center of the plant up to more light. This will encourage the second flush of blooms. Once your weather turns really cold, the tops of your plants will die down. When that happens, prune off the dead stems and mulch over the top of the plant with organic matter. In the spring, brush away the mulch and wait for new stems to develop. Pinch the stems back every 3-4 weeks to encourage lots of branching (and lots of potential flowers). Stop pinching back in mid-July so the plants can develop flower buds. You can thin out the clusters of flower buds to promote fewer but larger flowers. Next fall they will begin to bloom for you. Enjoy!
