Care and Culture of Hibiscus


Hi, my name is Byron Martin here at Logee’s, and today we’re going to be talking about Hibiscus; in particular about
Tropical Hibiscus. This is the genus rosa-sinensis of the
Hibiscus family. There are many forms of rosa-sinensis in
the trade, and they’ve been hybridized for a very long time. And the coloration
of the flowers is really extraordinary. There’s so much diversity in the color,
it could take years for one to collect or even become familiar with the amount
of beauty that is found within this genus. So, the genus Hibiscus is a large family
of plants that are found throughout the world. We have some that actually are in
the temperate areas, but many of them grow in the tropical areas, and as I
mentioned, there has been a great deal of hybridization on these. What we’re
talking about today are some of the fancy-flowered Hibiscus; this is a variety
called ‘The Path.’ It’s an older cultivar, but has never
lost its glamour or enamour of the gardener, with the beautiful coloration of
the flowers. So, basically, we need to ask, “How do we
grow these?” – and they’re actually quite easy to grow. The requirements for
growing any Hibiscus, or any of the Mallow family plants, generally, is that they
need a very high light level, and that means full-sun exposure. Where these grow in tropical areas, they always are used outside in plantings where there’s full sun exposure. So, as a container plant, that is what we want to grow them; in a
bright, sunny window, outside in the summer time on a patio. In cultivating,
them, along with sun, they are plants that actually prefer
warmer temperatures. Now, they can take short dips down into
the lower 40s, even 30s at times, but
generally our rule of thumb is to keep them above 60 degrees. The soil needed for grow them is
generally a standard potting mix. Here at Logee’s, we use a peat lite mix; they
do fine with that. We’ll talk a little about fertilizer in
a minute, but, generally, a well-draining mix. Peat moss, perlite, vermiculite;
maybe some compost added. Also part of culture, is water. And watering of Hibiscus
is pretty simple. Allow the soil to become visually dry,
like we do with most of our plants, and then thoroughly saturate the soil. A little
will never hurts; actually, a little wilt is good. Don’t
let them go into a severe wilt. And remember that stress on a plant with dryness is
reduced when you have proper fertilization. So, you get less damage
even if you do forget to water it, if your plants are fertilized properly. An
elevated phosphorus level — that’s the middle number, where you might have a 7-9-5 —
can help promote flowering on Hibiscus, but, generally, you want to make sure that
you have a balanced fertilizer going into the plant throughout its growing
season. They are relatively rapid-growing plants, so they do need to have a
constant supply of fertilizer when grown in containers. Otherwise, the plants will actually
yellow, slow down their growth, and your flower production will be reduced. So,
thank you for watching today. There’s a little bit of information on how to grow
some of these beautiful tropical gems. If you have more questions, or would like

  1. I love these plants and have bought a number from you.  However, I eventually have trouble indoors with them due to pests, mostly whiteflies.  Are there good ways to prevent pests without dangerous chemicals?  Thanks

  2. Just so I understand – do you fertilize during the winter? I live in Canada where I bring in my hibiscus plants (in pots) about September when the temps dip into the 40's at night.

    I find they go dormant in winter (so don't feed them) and I put them either in south or north facing windows. South get more sun, of course, but since they're not flowering, does it matter? I found the north windows to provide adequate light with slightly cooler temps (as there is no direct sunlight to heat up the plant). Would appreciate some advice. Hope this is not too long! Thanks.

  3. Thank you for this short presentation. I was looking for a short "how to" that hit all the major points to show to a friend who has a potted hibiscus. This hit the major points, was concise, and clear.

  4. Help my hibiscus' leaves are turning yellow and I live on a tropical island it gets full sun
    Do you guys think it's too much sun?

  5. Will they be ok outside all year long In sunny Arizona in a container pot….And can you use them to make hibiscus tea with

  6. My hibiscus plant is healthy but the flower only opens 1 day and closes then fall off is this normal? Thank u please help.

  7. I'm looking for the Rose of Sharon variety …also known as Rose of Monrovia…can you Help???
