how to grow tropical hibiscus in cold
Forget about planting hibiscus in the ground! The ground temperatures drop too low in winter, particularly where long, cold winters are experienced. Plant them in pots, preferably plastic ones, which retain more warmth than terra cotta or cement, and are a lot easier to handle. Don't use too large a pot; nice plants can be grown in 20 cm (8 in) to 30 cm (12 in) pots, and remember you are the one that has to move it around from place to place whenever necessary.
