Regulating plant growth should include
- pinching
- practicing recommended pruning procedures for selected plants
- identifying and comparing plant growth regulators, including auxins, gibberellins, abscisic acid, cytokinins, and ethylene

- managing plant growth and flowering by chemical and/or nonchemical means
- varying the spacing of plants.
