If you deadhead your black-eyed Susans, their blossoms will bloom for a longer period of time. Deadheading refers to the practice of removing spent, faded, or dried out flowers from the plant once they have passed their prime. Be sure to leave some flowers after the blooming process has slowed down, though, so that the seeds they generate can be consumed by birds and used to start new plants the next year.
After the flowers have formed, what should be done with black-eyed Susans?
If you prune your black-eyed Susans regularly, you may be rewarded with flowers throughout the entire growing season. As the blossoms on the flower plants begin to droop in the summer, cut back the flower stems. Remove one-fourth of an inch of the stems from above the highest leaf. Plants that have had their growth pruned may produce flowers again in the autumn.
Should the black-eyed Susan plant’s growth be trimmed after it blooms?
Every three to four years, perennial types should be divided in order to maintain healthy plants and prevent excessive spreading. Be sure to remove any blooms that have withered or died in order to encourage continued flowering. After the black-eyed Susans have finished flowering, you can trim them back, and sometimes they will produce a second, smaller bloom in the late fall.
How do you get black-eyed Susans ready for the winter?
If you want your flowerbed to seem neater during the colder months of the year, cut the stalks of perennial black-eyed susans back in the late fall after the plant has died down to the ground. Reduce the length of the stalks so that there is a four-inch gap between the bottommost basal leaves of the plants and the stalks.
Do Black-eyed Susans have the ability to spread?
Plants of the black-eyed Susan variety often reach heights and widths of between 24 and 36 inches. If conditions are favorable, plants have the potential to propagate themselves by means of subterranean stems and by self-sowing. You can control the proliferation of the clumps by dividing them once every four to five years. Self-seeding can be prevented by removing wasted blossoms in the autumn.
