If you live in an area that is too cold in winter for outdoor hibiscus, another option is to move hibiscus outdoors to patios or balconies during the warm months and indoors for winter. Attending to the specific needs of your hibiscus will encourage it to grow healthy and strong, even inside.n evergreen shrub with abundant flowers, hibiscus is most often planted as a shrub in outdoor landscaping. It is possible to grow hibiscus in containers indoors if you have a spot that receives full sunlight for at least six to eight hours a day.
Soil and Fertilizing. Plant your hibiscus in fertile soil. If planting a hibiscus outdoors, amend the soil with peat moss and perlite or vermiculite. If planting your hibiscus in a pot, plant it in a mixture of peat moss, perlite or vermiculite and a balanced potting soil that has been formulated for container plants.
