When planting hardy hibiscus, it is best to do so in early spring once the threat of frost and freeze has passed. The soil temperature should be at least 45°F or higher before planting. Additionally, the plants prefer full sun or part shade and require well-drained, moist soil.
Before planting, it is important to add fertilizer and a 3-4 inch layer of compost to the planting area. Planting each hardy hibiscus 4-6 feet from the next will help ensure the best results. When planting, place the roots in a shallow hole and cover with soil.
Once planted, water deeply and make note of the planting location for reference in future years.
How do you grow hardy hibiscus outside?
Growing hardy hibiscus outside is not difficult, and these stunning flowers will really add a pop of bright color and texture to your garden. To begin, look for a spot in your garden with full sun, at least 6-8 hours of direct sunlight per day.
Hardy hibiscus prefer moist, well-drained soil, so if your soil tends to be dry or sandy, consider amending it with plenty of organic matter (such as compost or aged manure). If you have poor soil, planting your hibiscus in a raised bed can be an effective solution.
If you can, test your soil pH and aim for a level between 6.0 and 7.0.
Plant the hibiscus in spring, starting with a young plant if you can. Dig the hole slightly larger than the pot it’s in and add some rich compost. Gently slide the plant out of the pot and into the hole, and backfill with soil.
Plant hibiscus with 8-12 feet of space between each one, more if you are planting larger varieties. Water after planting and keep the soil moist.
Mulching will help keep weeds down, retain moisture, and suppress temperature fluctuations. Use a 2-3 inch layer of shredded bark, pine needles or cocoa hulls. You can fertilize the hibiscus with a granular, slow-release fertilizer when you planted them and then again in early spring and mid-summer.
Hibiscus can be prone to powdery mildew if conditions are right, so it’s important to air the plant out if that happens. Cut away the affected parts and then thin out overcrowded areas to ensure good air circulation.
The hardy hibiscus should give you plenty of long-lasting and beautiful blooms in summer with regular care, and then go dormant in late fall or winter.
Are hardy hibiscus easy to grow?
Yes, hardy hibiscus are generally very easy to grow and maintain. They are very low-maintenance flowering plants that do not require large amounts of care and attention. They prefer sunny locations and will thrive when planted in soil that is loose and well-draining.
Due to their hardy characteristics, they are quite tolerant to a range of soil, moisture and temperature levels. The best time to plant hardy hibiscus is in spring or just before the first frost of autumn.
When planting, it is important to make sure that the soil is well-aerated and moist. The plants should be fertilized monthly with a balanced fertilize that is suitable for blooming plants, and If the soil is particularly poor, you can also add potassium and phosphorous.
Additionally, you need to be aware of pests and diseases that can affect the hardy hibiscus. The most common is aphids and earwigs, although these can be treated with insecticides if the infestation is severe.
It is also important to monitor the leaves, flowers and stems of the plants and remove any damaged or diseased ones in order to prevent any spread. With the right amount of care and attention, hardy hibiscus will flower profusely during the summer months and make a great addition to any garden.
Do hardy hibiscus come back every year?
Hardy hibiscus is a type of perennial flower, meaning they are able to come back and bloom year after year. However, they require the right growing conditions and the right care to come back reliably.
They are hardy in USDA Plant Hardiness Zones 4 – 9, so if you live in an area that falls within this range, you can usually count on them returning year after year. In colder zones, it may require protection or mulching over the winter months to ensure they are able to return.
It is also important to properly care for them by providing water, sun, and good soil. If all these conditions are met, you can often expect a reliable return of hardy hibiscus each year.
What do you do with hardy hibiscus in the winter?
When it comes to hardy hibiscus plants during the winter, it is important to take a few precautionary steps to ensure their survival. In climates that stay above freezing during the winter months, you simply need to mulch the plant with a thick layer to help keep the roots from freezing.
In areas where temperatures can drop below freezing, you will need to place the plant in a sheltered spot to insulate it from the cold and wind. Additionally, if the ground freezes in winter months, you can dig the roots up and replant them in pots filled with soil.
You can then move them to a warm area or greenhouse for the duration of the winter. Additionally, it is important to make sure the soil is adequately moist in the wintertime, but be careful not to overwater the plant.
Fertilizing the hardy hibiscus should also be done sparingly in the winter, as the plant should be dormant when temperatures are low.
Will hibiscus survive a freeze?
Hibiscus plants are originally from tropical areas and can be grown in tropical climates and in subtropical climates with mild winters. Generally speaking, hibiscus are not able to survive extreme winter temperatures and freeze events.
However, certain hibiscus varieties such as Hardtack Hibiscus, Texas Star Hibiscus, or Southern Belle Hibiscus, are bred to withstand temperatures down to 28 °F (-2 °C). In order to survive a freeze, hibiscus should be grown and managed properly and provided with extra protection in the winter.
This means providing a layer of mulch over the soil and insulation, such as a frost cloth, to protect the foliage from frost damage. Additionally, it is important to properly prune the plant to encourage a compact shape, healthy growth, and an even distribution of leaves to retain the warmth of the sun.
Finally, it is important to keep the hibiscus well watered throughout winter, as the roots will take the moisture and the moisture will protect the plant from the cold temperatures. With extra protection and proper management, hibiscus may have some success in surviving a freeze.
How do I know if my hibiscus is perennial or annual?
Determining if a hibiscus is perennial or annual can be difficult, as there are many varieties of hibiscus, and each variety has its own characteristics. Generally, if you live in a warmer region, most hibiscus plants are considered perennials, meaning that they will come back year after year, coming up from the same root system.
In cooler regions, however, many hibiscus plants may be grown as annuals, since they may not survive the winter outdoors.
One way to determine if your hibiscus is perennial or annual is to look at its leaves. Perennial hibiscus typically have large, leathery, and elongated leaves, while their annual counterparts tend to have smaller, rounder, and softer leaves.
Another way to tell is by looking at the overall size of your plant; perennial hibiscus will be larger and fuller than annuals, especially during the winter.
Finally, if you want to be sure that your hibiscus is a perennial, you can check with your local nursery or garden center to find out what variety of hibiscus it is, as well as any additional care requirements.
This can help you ensure that your hibiscus is able to survive and thrive for many years to come.
How do I revive my hibiscus plant after winter?
Reviving your hibiscus plant after winter can be done easily. Firstly, you should give the plant a good trim. Cut off any dead, diseased or frail stems, then prune the plant back if necessary. If the plant is still in its pot, you should take it outside for some extra light and air.
Make sure the potting soil is refreshed and that the pot has adequate drainage so your plant doesn’t become waterlogged.
Next, you should check the plant’s roots. Healthy roots should be white and firm, any brown, weak or too-narrow roots should be trimmed back. Re-pot and refresh the soil if necessary.
Once the care is taken of, you should give your hibiscus a good dose of fertilizer or compost. This will help this plant start regaining its strength. Water consistently while the plant is reviving, and be sure to keep the soil moist but not waterlogged.
Finally, check the plant’s leaves and branches every so often. Remove any yellow or discolored leaves as they may be infected. Once the hibiscus starts to show signs of new growth, you can move it outside and tolerate the full sun and summer heat.
This will be the final step in reviving your hibiscus plant after winter.
Should I cut back my hardy hibiscus?
Whether or not you should cut back your hardy hibiscus will depend on its current condition. If the hibiscus is dead or diseased, it should be cut down and removed. If the hibiscus is still healthy and blooming, it can be trimmed back to a desired shape and size.
Prune lightly and selectively to maintain the desired shape and size. Make sure to only remove dead, diseased, or damaged branches. Make sure to use sharp, sanitized pruning tools whenever trimming hibiscus plants.
Regular pruning will encourage healthy growth and abundant blooms.

Can rose of Sharon be grown as a tree?
Yes, Rose of Sharon (Hibiscus syriacus) is a deciduous shrub that can be grown as a tree. It is possible to train and prune the shrubs into a tree form, or you can find varieties that are already grafted onto attractive trunks and will grow as trees.
Rose of Sharon is a fast-growing shrub that blends well with other trees, shrubs, and perennials, and can be grown in a variety of soils and climates. The shrubs will grow to a height of 8 to 10 feet and have a spread of 8 to 12 feet, but with pruning can be kept at a manageable height.
The tree-like form will produce the same beautiful blooms and foliage as the shrub, including the fragrant white, pink, lavender and red blossoms, and attractive, dark green foliage.
Should you cut back rose of Sharon in the fall?
Yes, you should cut back rose of Sharon in the fall. Pruning it back helps eliminate branches that are crossing, dead, or diseased; stimulates new growth; and provides a more attractive and healthy appearance for the shrub.
It also encourages more flowers for next season. To prune properly, first remove any crossing and dead branches. Spend a few minutes assessing the shrub and make sure to leave some branches with buds on them to help with the shrub’s growth.
Finally, take off one third to one half of the shrub’s total length, making sure to cut the branches into small sections. With the right pruning, you can get your rose of Sharon looking its best going into the next season.
Is rose of Sharon poisonous to dogs?
No, Rose of Sharon (Hibiscus syriacus) is not considered poisonous to dogs. However, all plants may cause digestive upset if eaten in large amounts, so it is best to keep animals away from it if possible.
Mild skin irritation may occur if the plant is touched and ingested. More serious symptoms, including respiratory difficulties, may occur if ingested in larger amounts. If your dog is exhibiting any signs of distress, contact your veterinarian right away.
Can you turn a Hibiscus bush into a tree?
Yes, you can turn a Hibiscus bush into a tree. When you first plant your hibiscus, you should start with a young, healthy bush, and stake it in the ground firmly so it will not sway as it grows in size.
As the Hibiscus grows, you can remove the lower branches and heads to thin it out and allow for increased light, air and water circulation around the trunk of the tree. You may also need to do some pruning and thinning to encourage new growth and long branches.
As the bush continues to grow, you should continue to prune and shape it to create a single trunk and canopy in the shape of a tree. With proper care and maintenance, you should be able to eventually create a healthy, vibrant Hibiscus tree.
Can you shape rose of Sharon?
Yes, it is possible to shape a rose of Sharon shrub (Hibiscus syriacus). Pruning is a crucial factor to shaping the plant, and this should be done in late winter, early spring or in late summer. Ideally, rose of Sharon should be pruned back to within two feet of the ground in late winter.
This encourages vigorous new growth and keeps the plant a reasonable size. When pruning, cut back any weak, old, thin or sucker growth with bypass pruners. Keep in mind that only ½ of the current season’s growth should be removed overall.
It is also important to establish the desired shape before pruning. This can be accomplished by pruning any outward growth, aiming for smooth lines in the process. Consider removing longer branches first and then prune sides and inner branches.
Then, use your hand pruners to thin out any flower buds to reduce the quantity of blooming. To prevent stress on the plant, it is better to prune small sections of the shrub at a time instead of the entire thing.
Finally, cutting out dead or diseased branches will ensure that the rose of Sharon looks its best.
Is Purple Pillar Evergreen?
No, purple pillar is not an evergreen plant. Purple pillar is actually a variety of the Utah juniper, which is a deciduous shrub. It is native to the western United States, mostly in Utah and California.
It has a narrow, upright form, and its grayish-green scale-like leaves are often edged with purple, giving it its name. The leaves are usually 1-3 inches long, and they turn yellowish-green in fall before dropping off.
The shrub blooms in the spring, producing small greenish-white flowers. Purple pillar is a low-maintenance shrub, making it a popular landscape choice, but because it is deciduous, it does lose its leaves in winter.
How fast does purple pillar hibiscus grow?
Purple Pillar hibiscus typically grow at a rate of 18-24 inches (45–60 cm) per season. Since they are fast-growing and robust, they can attain up to 8 feet (2.4 m) in height. They can also spread up to 3 feet (90 cm) wide.
Typically, they flower abundantly in the first two years, but after this initial growth period, growth slows down. With proper care and pruning, a single plant can last several years, with flowers blooming every season.
For best results, they should be grown in full sun and rich, moist, well-drained soil with a pH of 6.6-7.5.
