Treat the plant as you have in past years by cutting it back as needed to fit in the house and moving it inside. These plants need five to six hours of full sunlight a day to perform well while inside. Since the hibiscus is tropical and does poorly in cold, rainy weather, it is best to bring it inside before nighttime temperatures drop to 40 degrees.
A light freeze over a couple of nights can kill these plants. Keep your plant in a relatively small pot, since hibiscus flowers best when its roots are crowded. Try giving your plant a rest for a few months when you bring it in by minimizing pruning, reducing watering and moving it to a cool room with bright light.
Do not push it to flower over winter. It is likely that some leaves will turn yellow and fall off as the plant adjusts to a new environment inside. In March, cut the stems back, move the plant to a sunny location and increase watering. Normally, you would fertilize once new growth appears, but I would skip this step next year.
The stunning blooms of the Hibiscus are what make it such an appealing plant to have around the home or garden. Hibiscus need lots of sun to make flowers. Thus, too little sun is the main cause of a Hibiscus not flowering. A Lack of flowers could also be due to a pest infestation. Tropical Hibiscus loves the sun which means that it needs a very bright spot in your home or garden. If your Hibiscus lives indoors then you should move it to a brighter spot in the house.
Outdoors, potted Hibiscus should be moved to a brighter part of the garden. So you should avoid doing this. Find more creative ways to give it sunlight instead.
One way to do this is to avoid pruning stems that are reaching out to the sunlight. These leaves can catch the light and divert the energy back to the rest of the plant. Hibiscus are tropical plants which means that they like warm humid conditions.
If your hibiscus is in a shadier location of your garden then the less energy the plant has for as display of flowers in Summer. Hibiscus are indigenous to the sunny and humid tropical and subtropical climates in Asia where they flower in full sun and warm weather. Always locate your hibiscus in an area with 6 or more hours of sun whether they are a variety of the tropical species of hibiscus Hibiscus rosa-sinensis or the hardier species of hibiscus Hibiscus spp.
If your hibiscus is in a shady area of your garden or indoors then the plant is living in conditions that are contrary to its requirements which causes stress and prevents flowering.
If possible cut back any vegetation that is casting shade on your hibiscus or ideally if its potted move it to a sunny patio. Only the tropical varieties can grow indoors hibiscus are not necessarily the best houseplants but ensure that your hibiscus is in the sunniest window of your house to promote blooms.
An accumulation of phosphorous in the soil prevents the hibiscus roots from up-taking other essential nutrients which can stop your hibiscus form flowering an even kill the plant. Avoid any fertilizer that is not well balanced a well balanced fertilizer has an even ratio of Nitrogen, Phosphorous and Potassium NPK and avoid any heavy use of fertilizer, prioritizing improving soil fertility with organic mulches such as well rotted manure.
Hibiscus is unusual in its sensitivity to phosphorous so this can be a frequent cause of the flowers not emerging for gardeners as it is quite a specific problem. Too much phosphorous is one of the causes of hibiscus leaves turning yellow however there are several reasons why hibiscus leaves turn yellow so I wrote another article for the solution. Hibiscus are sensitive to too much phosphorous and even nitrogen when you use fertilizer in too high concentration.
Too much nitrogen causes your hibiscus to grow foliage at the expense of blooms so its important to moderate your applications. Hibiscus are heavy feeders but as stated the best way to feed them is to add mulch to improve the soil compost, leaf mold or well rotted manure an perhaps use a half strength general liquid fertilizer from a brand such as miracle-gro, once a month during the Spring and Summer. This is often a good balance to provide the hibiscus with the nutrients it requires to display flowers without over indulging the plant and causing it not to flower.
If your hibiscus has no flowers but lots of foliage then scale back the use of fertilizer and water it regularly. It may not display flowers this year but with a more diligent approach to fertilizing the hibiscus should flower the following year.
Hibiscus flowers on new years growth so pruning in the growing season can have a serious impact on blooms. A heavy pruning in the early Spring can either cause the hibiscus to not flower in the Summer or to delay flowering significantly. If flowering is delayed then the flowers are more likely to emerge when the temperature is cooler in the Fall rather then in the height of Summer and often wilt or drop far quicker then they otherwise would.
The same reasons for hibiscus not flowering also apply to potted hibiscus but there are a few conditions that specific to pots that may cause your hibiscus not to flower.
If your hibiscus has been growing in the same soil for many years then you should re-pot your hibiscus to promote plant health and flowering. Re-pot with quality multi purpose compost for good soil structure and moisture retaining capacity. Re-pot the hibiscus in a larger pot so the roots can establish and access the nutrients and moisture they require for flowering without drying too quickly in the intense Summer sun.
It lives indoors during the cold times then inside in winter. I have had it for 25 yrs. One time it had one very tiny flower, and that is all…. Our hibiscus bushes were doing fine — lovely bushy plants with green leaves and abundant flowers. While we were gone our gardener allowed the bushes to grow very tall and then cut them in September right before we returned.
They have not flowered since. Would the season that he cut them have caused them not to flower again? Thank you for your help! The leafs are turning yellow everywhere. It was amazing this summer outside. But when it got around 65 I brought it in. And since then the leafs have been falling off. I think i got it, brother you need to lot of pottasium and need to check the pH of the soil which should in between but not more than seven. Fertilizer required by plant N,P,K respectively,i hope this will work.
I live in Pa. My hibiscus is about 4 years old. I keep it in a large pot inside all winter and put it outside in the summer. The first summer I got lots of flowers, usually 1 a day When I brought it inside in about 2 weeks it started to bloom again. This has been happening each fall. Is my plant backwards. My Hibiscus did basically the same thing. I am in Dallas with extremely hot summers. I was getting no blooms on my patio. So I brought them all inside and put them in front of an East window.
My ac was on 70 degrees. They immediately started blooming inside. I did buy 2 hibiscus from one place this year that just died. They were really dry at the store when I bought them thinking I could save them. Hibiscus seem to like the same temps we humans do.
I bought some organic Hibiscus fertilizer online with a lot of potassium they seem to do well with. And about once a week I give each one about half cup of cold black coffee. That really perks them up. I think too you have to be careful and buy the old familiar names of Hibiscus. And buy them at reputable gardening places. During the winter I kept my hibiscus in the basement. It lost all of the leaves but this spring it put on new leaves and is beautiful. The problem is that there are no blooms.
