Remove the lower leaves and dip the stem into rooting hormone powder. Plant the cutting in moist soil or compost and keep it in a shady spot. It's best to keep the soil moist but not overly wet. The cuttings should root in six to eight weeks, and new growth should emerge from the top of the cutting.
Propagation of Euphrasia stricta is an easy process that can be done using various methods. Once propagated, proper care and maintenance of the plant will ensure continued growth and flowering for years to come.
