How do black eyed Susans grow?

Black-eyed Susans produce fibrous roots that spread horizontally in the soil. They do not dive deeply because they take advantage of the ample nutrients and moisture in the top 24 inches of soil for maximum growth. As the roots spread, they swell into clumps -- these engorged areas store nutrients and moisture for future use. If you pull black-eyed Susans from your garden and leave some root pieces behind, the clumps eventually produce a new plant. You can create a constant supply of new flowering plants by dividing the clumps in the fall after blooming. By cutting a clump in half and planting the pieces separately in the garden or containers, you effectively propagate this flowering plant.

Do black eyed Susans need post bloom?

After summer blossoming, you may be tempted to cut the plant down to avoid unsightly foliage and blossom fade. However, black-eyed Susans need their postbloom foliage. As long as it is still green, the leaves are photosynthesizing. This energy enters the roots for future blossom growth and sustenance. By cutting off the foliage directly after flowering, the roots lose potential nutrient and energy storage for next season's flowers. You may see only foliage the next year and no flowers if the plant does not have the energy for development.
