A single application of general-purpose fertilizer in the spring is enough to keep the plant healthy and blooming. Over-fertilizing can lead to excessive foliage growth and a reduction in the number of flowers.
Pruning
The plant can be pruned to maintain its shape and promote blooming. Deadheading the spent flowers and pruning back the stems just above a node can encourage branching and more flowers. Pruning must be done after the blooming period. The plant can also be cut back to the ground in the fall to promote healthy growth next spring.
Propagation of Heterotheca Sessiliflora (Nutt.) Shinners ssp. Echioides (Benth.) Semple var. Camphorata (Eastw.) Semple
Heterotheca sessiliflora (Nutt.) Shinners ssp. echioides (Benth.) Semple var. camphorata (Eastw.) Semple can be propagated by different methods. These include:
Seed Propagation
The most common method of propagating Heterotheca sessiliflora (Nutt.) Shinners ssp. echioides (Benth.) Semple var. camphorata (Eastw.) Semple is through seed. The plant produces numerous small, black seeds that can be easily collected and sown. The seeds can be sown directly in the ground or started indoors in seed trays.

Cuttings
Another way to propagate Heterotheca sessiliflora (Nutt.) Shinners ssp. echioides (Benth.) Semple var. camphorata (Eastw.) Semple is through stem cuttings. Cuttings should be taken in the spring or early summer when the plant is actively growing. Cuttings should be about 6 inches long and include several pairs of leaves. Dip the cut end of the stem in rooting hormone and plant in a potting mix that drains well. Keep the soil moist but not wet and place in a bright, indirect light until the cutting roots.
Division
Heterotheca sessiliflora (Nutt.) Shinners ssp. echioides (Benth.) Semple var. camphorata (Eastw.) Semple can also be propagated through division. This method is best done in the spring or fall. Gently dig up the plant and separate the root clumps into smaller sections, making sure each section has several stems and a healthy root system. Replant each section in well-draining soil and keep the soil moist but not wet until the plant establishes itself.
Disease and Pest Management for Heterotheca sessiliflora (Nutt.) Shinners ssp. echioides (Benth.) Semple var. camphorata (Eastw.) Semple
