German garlic can be propagated through division, cuttings, and bulbils, but each method requires specific steps. Division involves separating bulbs in early spring or fall, with each part having some roots. Cuttings are taken from stems in spring or summer, dipped in hormone, and planted in well-draining soil. Small bulbs or bulbils grow on flower stalks, can be picked and dried, then planted. For any method, use sterile potting mix, keep soil moist but not wet, and give filtered sun. Using more than one way raises the odds of propagating successfully. This results in higher numbers of new German garlic plants over time.
