In February or March, remove and replace the top 2 inches of your hibiscus' growing medium. Boost the effects of the fresh medium with a dose of slow-release, 19-6-12 indoor plant food. For each 10-inch pot, sprinkle 1 tablespoon of fertilizer, or the fertilizer label's recommended amount, evenly over the growing medium, and water the medium. Plants in larger pots require more fertilizer, as the fertilizer label directions indicate. Cut each branch back to a leaf node, wait for glossy, green leaves to emerge and move your hibiscus plants back outdoors when nighttime temperatures are consistently above 55 F. Set them in a shaded location, and move them a little closer to the sunlight each day for about 10 days, or until they acclimate to outdoor life.


First off, if you live in an area where temperatures stay below 50F (10C) for more than brief periods, you'll need to bring your hibiscus indoors to save it over winter. These are tropical plants and don't survive exposure to freezing temperatures. (That said, if you have a hardy hibiscus, which is sold in the perennials section of your local garden center, that plant can stay outdoors over winter. It will go dormant this fall, rest over winter, and produce new growth in late spring with flowers following in summer).hibiscus when the top inch or two of the potting mix dries to the touch (just like you would any other houseplant). I always found -- and I bet you will, too -- hibiscus require substantially less water indoors during winter than it did when you grew your plant outdoors. Happily, that makes it easier to care for! When I would bring my Tropic Escape hibiscus in for winter, I ended up watering it about once a week or so. The exact frequency you'll be watering is influenced by many factors, though, including how warm or cool your home is, the humidity levels, how big your hibiscus is, how big its pot is, type of potting mix, etc.

How to Grow Perennial Hibiscus. Similar to other perennial plants, rose mallow usually dies back completely to the ground in winter. Just cut back the stems to a few inches in height in late fall or early spring, and you'll see new shoots emerge when weather warms again. How to Keep My Hibiscus Blooming Re-pot your hibiscus in January or February of every other year. Cut the plant back by 1/3 to 1/2 in very early spring. Place the plant outdoors in late April in a location that receives full sun all day or at least for six hours. Fertilize the hibiscus every two weeks. (Source: askinglot.com)


The Genus Cornus: Woody Cornus (dogwood) species are medium to tall, deciduous shrubs, usually with opposite leaves and branches, except for Cornus alternifolia, which has alternate leaves. Dogwood leaves are broadly-elliptic with several pairs of parallel veins that curve towards the tip (apex) of the leaf. The numerous small flowers have parts in multiples of four (4-merous) and are arranged in large, flat-topped inflorescences.

The dogwoods are distinguished from other flowering shrubs by the clusters of small, 4-petaled white flowers and opposite (except for 1 species) leaves that are toothless and have prominent, arching, lateral veins. Like our other dogwoods, Round-leaved Dogwood is an understory species of upland forest, both hardwood and conifer. Semi-shade tolerant, it prefers thinner canopies or openings and wood margins. The leaves may be confused with those of Pagoda Dogwood (Cornus alternifolia), which are typically not as broad, are alternate, and have 5 or 6 veins per side, where Round-leaved Dogwood leaves have 6 to 9 veins per side, are opposite and typically much rounder, plus the shrub's form lacks the layered branches of Pagoda Dogwood.
