This procedure will keep the roots warm and prevent them from drying out. Rudbeckia is susceptible to attack by spider mites and leaf-gnawing caterpillars, so you should carefully examine the plants. When signs of diseases or pests appear, treat with chemicals.

Plant propagation

Annual species of rudbeckia reproduce using seeds. Perennials can also be propagated by dividing the rhizome. When propagated by seeds, sowing takes place in early spring, late March or early April.

• Prepare containers with a mixture of peat and sand. Since the rudbeckia seeds very small sow they are lightly sprinkled with earth on top of the substrate and on top.

It is best to choose a warm period for planting in open ground, when the ground is already warmed up. For this, the middle or end of May is suitable. Seedlings are planted in prepared holes at a distance of 30 cm.

Reproduction by dividing the rhizome occurs when a perennial is transplanted.
