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)


I feel guilty even saying it, but I really do not particularly like Anemone cylindrica. It is a perfectly fine native plant, with a lovely mound of green leaves and interesting seed heads. It can grow in really, really dry shade. It is even easy to propagate from seed and can be transplanted mid-season without major trauma. So why don’t I just love it? Because the same can be said about Anemone virginiana, but A. virginiana has pretty flowers. Oh, A. cylindrica has interesting flowers, greenish white with the "petals" all curled up into little pointed triangles. But the real problem is that the two anemones look the same to the interested non-specialist, unless they are blooming. And I have spent many years (cumulative) caring for little seedlings only to find when they bloom that they are A. cylindrica. Off to the back 20 they go. Plant the new bunch that surely will be A.

The species has a long flowering period, blooming from early to mid-summer. In late fall the thimbles begin to break into cottony tufts that can last through the winter. This plant produces an allelopathic substance, protoanemonin, which inhibits seed germination and seedling growth of many species of plants. It is said that mammal herbivores usually avoid consumption of this species because the foliage is toxic, causing a burning sensation in the mouth and irritation of the gastrointestinal tract. However, the deer in my neighborhood are tough, and decimate the flower stalks of every clump outside the deer fence. They do avoid the leaves. (Source: flnps.org)
