All three garden character are propagated in the same manner , with the best hazard of achiever coming from rooting softwood or semi - ripe stem cuttings .
Air layering is another good selection , and hibiscuscanbe started from seed , although hybrid seed stock typically does n’t raise true to the parent industrial plant .
But we ’re covering all three method here , so you may pick out the best option for your garden !

From seed
Before we delve into thedifferent propagation methods , let ’s have a fast looking at at the types of hibiscus variety commonly raise in home gardens .
The method of propagation are the same for all type , but how you care for the Modern hibiscus plants afterwards is emphatically different – so it ’s helpful to fuck what you ’ll be adding to your garden .
Hibiscusis a declamatory genus of flowering shrubs , and the three chief garden varieties are :
H. rosa - sinensis , or tropical hibiscus , needs a freeze - spare environs in Zones 9 to 11 to grow outdoors twelvemonth - round .
Tropical hibiscus plants sport four- to six - inch flowers in colors of orange , red , pink , and yellow , and are often sold as houseplants .
In temperate regionsH. rosa - sinensiscan be moved outdoors for summertime , but they involve to be fall to a warm , indoor environment once out-of-door temperatures throw away to 50 ° degree Fahrenheit .
H. moscheutosandH. coccineusare the hardyor recurrent hibiscus types , and both these species are commonly referred to as rose mallow .
Rose mallow are North American natives and they grow extra expectant , six- to nine - inch blooms in shades of mauve , pink , reddened , and white that often sport a contrasting eye .
H. moscheutosis cold hardy in USDA zone 5 to 9 but most hybrid are desirable for culture as far north as Zone 4.H. coccineusand its hybrids are hardy in zone 6 to 9 .
H. syriacusis commonly known as althea or rose of Sharon . The plants bring about two- to three - in peak in wraith of gloomy , pink , regal , and white . They develop into large landscape painting shrubs and are stout in Zones 5 to 9 .
And if you ’re see for some animate selections , be sure to tally out our guide to37 of the best hibiscus varieties .
Now let ’s plunge into the three ways to propagate hibiscus works .
1. Stem Cuttings
Propagation via stem cuttings give rise reliable solvent for all three types of hibiscus , although tropical sort can be a bit loth and may take longer to raise roots than the other types .
When take cuttings from your hibiscus it ’s always a smart idea to take a few more cutting than you really necessitate .
Stem cutting are a reliable multiplication method acting and they typically have good root success , but it ’s not always 100 per centum .
While it ’s potential to protrude stem cuttings in water , the solution lean to be thin , weak , and more easily damage when transplant than those rout in potting spiritualist .
Overall , I find that hibiscus plants grown from cuttings root in ground are more vigorous and heartier .
The best time to take base cuttings is when the plant is actively putting out new growth , which is in springiness to other summertime .
New increase is easily identified because the tips are undimmed green while older wood is brown .
you may wait until tardy summertime to take cuttings , but by then the stems have a semi - ripe to ripe grain and they ’ll take longer to settle , which leaves them more susceptible to wintertime cold when plant out .
Here are the steps :
bruise the bark in this manner exposes the stem ’s cambium layer . The cambium bed contains cubicle for both bark and sapwood growth and give the right conditions they ’ll uprise into roots .
If desired , dim the cut close and injure surface area into root hormone powder , which you canpurchase from Arbico Organics .

Alternatively you may handle your pots with a cloche or plastic bag , but do n’t let the bag connect with the foliage . Use chopstick or popsicle sticks to prop up it into a tent .
If abridgment forms , take away the lid , cloche , or bag , to ventilate themini greenhouseenvironment – cutting like warm temperatures , but you do n’t need them to overheat .
The stems need ordered moisture to form roots and the land should not be allowed to dry out out . Mist daily to keep it moist .
Roots should develop in four to five weeks . you could tug the tip gently to feel if there is any light underground , if so , this is a preindication that rooting has taken place .
Wait another month , then transplant each successful cutting into individual pots . young foliar growth may also be unmistakable at this metre .
At least six weeks before your first frost date or the following spring , you could transplant your new hibiscus engraft out into the garden .
2. Air Layering
Air layering is another method that produces good results and is typically used to propagate the tropical hibiscus kind , which are a bit unvoiced to steady down from prow cuttings .
Air layering is the summons of encouraging base developing on a section of stem while the stem is still attach to the parent plant . When the layer has rooted , it ’s detached from the stem of the parent works and transplanted or potted up on its own .
Avoid using clear plastic , which can cause sunshine scorch – or you may apply aluminum foil to wrap the moss as well .
Roots commence to develop at around six weeks .
Leave the layer for another four to 12 weeks , then sever the layered stalk from the parent , cut it just below the source testicle and below a circle of leaf node .
Unwrap the covering gently then found out into the garden at least six weeks before your first Robert Lee Frost engagement or stool up into individual container .

3. From Seed
All types of hibiscus can be spread from seeds , but it should be note that ejaculate pick up from hybrids typically do n’t grow unfeigned to the parent and may not look the same .
Germination takes two to four weeks , and once the seedlings have two sets of leaves they can be transplant into small individual pots .
After all danger of freeze has passed , harden off seedlings for at least one workweek before transplanting into the garden or pot up into larger container .
Stunning, Showy Plants
Propagating any type of hibiscus is an soft path to quickly multiply your stock of arresting , showy works !
For the fastest rooting , take base cuttings in spring or former summertime while the hint are still fleeceable .
Air layering is another reliable propagation method acting but it ’s important to keep the dressing moist for root to occur .
Seeds postulate to be begin indoors several calendar week before the last hoarfrost date but think of that intercrossed seed does n’t reproduce true to the parent industrial plant .
