My spirea are burning up and the rest of my new flowers are great. This happens every time I plant them no matter where I plant them. What am I doing wrong?
Your spirea may need a little extra water if the temperature in your zone has been higher than normal. If your watering routine has been the same for the spirea and your other plants, that may need to change. Add some mulch around the plant to keep more moisture in, and watch the time of day that you water: don't get the foliage wet right before the sun will beat down on it for any length of time.
