Bee balm requiresfull sun , with a lower limit of six to eight hours per day needed for most potpourri to flower to their full voltage .

Less light may be fine in some cases , with three to six hours influence well for many varieties to produce decent blooms .

regrettably , the exact number of hours a give variety needs are n’t typically spelled out beyond a general description of “ full sunlight to part shade , ” so you ’ll have to look for signs of sunlight deficiency in your works to determine whether this is the way out .

The trick , then , is to stop it from produce cum by continually removing all spend flowers . This is refer to as “ deadheading , ” and will often ensue in a secondflush of flowerslater in the summer .
