Answer: It may be suffering from a deficiency of phosphorus. This nutrient is the least mobile of the major nutrients, so plants have a hard time absorbing it until soil warms and the work of microoganisims makes it available. A humus-rich soil kept well mulched should have plenty of available phosphorus. Apply a liquid seaweed fertilizer or Liquid Bone Meal (available from Gardener's Supply Co.; http://www.gardeners.com; ph# 800/863-1700) and it should recover to bloom next year. Hope this helps!
