sweet coneflower

Sweet Coneflower (Rudbeckia subtomentosa 'Henry Eilers') needs consistent watering to remain healthy, as it is a drought tolerant plant. Water the plant thoroughly once a week, making sure to saturate the soil completely. During the summer months, this can be increased to twice a week if required due to excessively hot and dry conditions. Make sure to reduce the watering during the winter months; just enough to keep the soil moist and prevent it from drying out. Discontinue the watering if rain is frequent in your area. In addition, the sweet coneflower should never be allowed to sit in soggy soil for too long or to become excessively dry - this can damage the plant and cause it to become susceptible to disease.

Sweet coneflower prefers full sun for at least 6 hours, preferably more. A location with morning sun and afternoon shade, or consistent all day filtered shade, can work for sweet coneflower. As long as it gets enough sun each day, this plant should do just fine.

Sweet coneflower (Rudbeckia subtomentosa 'Henry Eilers') requires minimal pruning. It is recommended to prune as soon as the flowers have died off, which will be usually by late summer or early autumn. This should be done no later than late autumn, as pruning after this could be damaging to the plant. The main thing to bear in mind when pruning sweet coneflower is to not cut too far back as this may reduce the flowering potential for the following year. It is best just to cut off the old flower heads, leaving some foliage at the base of the plant.
