Answer: Snow in Summer is an attractive spring and early summer bloomer. When the floweriing stops, shear the plant to encourage new growth. Cut off old flowers and an inch of foliage with bypass pruners. This will keep the plant looking healthy and tidy the rest of the summer. After shearing your plants back you can feed with a water-soluable fertilizer (Miracle-Gro or Peter's) to help it green up again.
Best wishes with your garden!
