Two different coinage are sometimes calledcitronella industrial plant . The plant used to make citronella petroleum , citronella grass ( Cympobogon nardus ) , is a tropical grass that grows as a perennial in U.S. Department of Agriculture plant hardiness zones 10 through 12 . The citronella - scented geranium ( Pelargonium citrosa ) , or mosquito plant , is a pinnace perennial in USDA zone 9 through 11 . Both can be grown as annual in frigid climate and you may also grow them in gage and bring them indoors for the wintertime .
Vegetative Propagation
Step 1
Citronella grass is a clumping works that divides easily to make more plant . The plant life is made up of many case-by-case clumps , call culms . Any culm can be take away from the parent works at the substructure and planted in a pot or in the ground . Using a shrewd jigaboo or trowel , slice down into the ground when divide culms to be trusted they are removed with some roots tie . piddle frequently until the unexampled industrial plant has establish a root arrangement and begin to farm . The oils in the plant may cause skin irritation or farm your heart rate , so be heedful when working with citronella plant .
Cuttings
Citronella - odourise geranium is easily propagated from stem newspaper clipping . Take the cuttings from the midsections of the stems because the stem tips are too indulgent and dry out easily , while the bottoms of the stems are woody and do n’t spring roots easy . The cutting should be 4 to 6 inches long , but more significantly they must have at least two leaf nodes — the raised buds along the shank that leaves or new stems can grow from . Remove all but the top two parting from the cutting .
Rooting
Stem clipping of citronella - scented geranium ascendent well in perlite , though you’re able to employ potting soil . Stick the cuttings into the rooting sensitive straight off so they do not dry out and place the pot in a warm patch with collateral or filtered sun . There should be at least one node above the rooting medium and one below the horizontal surface of the soil or perlite . Keep the steady down medium evenly moist and spray the leave with water supply daily . Roots should form within two weeks . The cutting can be potted until they are large enough to plant in the priming .
Season
Both works should be propagated in late springiness so they can uprise to full size before wintertime . If you ’re propagating to winter these stamp perennials , take the cuttings or divisions in early declension and keep them in a burnished , cheery window until outpouring . Water the plants on a regular basis throughout winter . Once all danger of frost has passed , you could set them alfresco .
