Hibiscus are a popular ornamental plant that grow in many types of climates. They have been used in traditional medicine for centuries. The genus Hibiscus includes over 100 species with only two being native to North America: H. lutea and H. longifolia (the lutea variety). These two species are both found in the temperate regions of North America. Both species produce flowers which vary from small white or pinkish flowers to large yellow ones.
The most common type of hibiscus flower is the bract, but there are other varieties such as the heart-shaped bracts, the trumpet shaped bracts, and even the star shape bracts. There are several different ways to make use of these various shapes and sizes of flowers.
When it comes to pruning hibiscus plants, one of the best things to remember is that they are all different. Some will need less pruning than others. The first thing you want to consider when deciding what kind of hibiscus plant you have is whether your particular plant needs a lot of care or not. If so, then cutting back may be necessary. Most hibiscus plants do not need to be cut back, but some do.
You will need to decide what level of care is necessary for your specific plant.
When it comes to pruning hibiscus flowers, you shouldn’t cut them all the way back to the ground. Instead you should prune them back to just above a joint. This will ensure that your plant grows strong and hearty.
One of the best things about pruning hibiscus is that it only really needs to be done one time. The idea that you need to continually prune an overgrown hibiscus plant is a myth. It takes a lot of experience to properly prune an overgrown plant and most amateurs will make the situation worse by over-pruning and killing the plant. Just remember one rule: cut back to a joint. Beyond that, you shouldn’t have to prune an overgrown hibiscus plant at all.
One of the best things about cutting back a hibiscus is that it will bloom again soon after. Your hibiscus should be ready to bloom by springtime. All you need to do is wait for the right time of year and then prune it back as described above. Your hibiscus should reward you with a beautiful show of flowers this spring!
Pruning hibiscus is an easy process. If you stick to the basics, you will have beautiful hibiscus blooms all summer long.
Hibiscus care continues to fascinate gardeners all over the world. It’s hardy, versatile and can be grown in most any area with warm temperatures. Although the plant is drought tolerant, it will grow bigger and bloom more if watered regularly. The hibiscus is known by many different names including the rose of sharon, the mallow and the florist’s mallow to name a few.
Although the plant can grow to a height of fifteen feet or more, gardeners growing hibiscus in containers can keep the plant to a more manageable size. If you do not want your plant to grow beyond four feet in height, simply cut the stem back to that height in early spring before new growth starts. This is also a good time to prune out any dead or dying stems from the plant.
Hibiscus care also involves controlling insects and diseases. Aphids can be a problem and can be dealt with by spraying the plant with soapy water. Other insects such as the cottony-cushion scale can be sprayed with horticultural oil.
A common virus that affects hibiscus is called mosaic. This is especially true if the plant is stressed in some way. If your hibiscus plant starts showing signs of mosaic, such as discoloration and mottling, do not remove it from the soil.
