If you ’ve overwatered your hibiscus , do not water it for one or two calendar week in lodge to let the stain ironic . you may examine it by beat your finger two inches deep into the potting intermixture to check . Also , lessen the common watering amount after the stain has dried out .

Temperature Stess Cause Leaves Curling
Hibiscus are tropical plants that can endure cold temperature . These plants like temperatures of around 60 - 95 ° F ( 15 - 35 ° C ) . Any temperature below 50 ° F ( 10 ° C ) will cause stunted development , curling leaves curl and spill .
Oppositely , constant temperatures of above 100 ° F ( 38 ° 100 ) can cause high temperature accent in your flora — this heatwave results in over transpiration in your plant .
Transpiration is when leaves release water supply from their leaves . Over transpiration or the release of too much pee causal agency curling , withering , and wilt .
If temperatures are cold , move the works indoors and order them somewhere sunny . That ’s why it ’s better to originate your hibiscus plant in a container , no matter the species .
A potted plant give you the ability to move it indoors in the colder months in orderliness to protect it from dropping temperatures .
If the temperature are too hot , move the plant to a well - shaded field and cloud the leaves to help cool down it down and take the stress of the roots .

Before planting , check your soil ’s pH with a pH cartoon strip or any other testing kit .
If the soil pH test shows that the pH is high-pitched than 7.5 , use sulphur , iron sulfate , manganese sulfate , or aluminum sulfate to lower it . If the pH is less than 5.5 , you could apply an agrarian lime or dolomite .
hold back two workweek and retest the pH of the soil to ensure that weather are idealistic before you plant your hibiscus .

However , hibiscus plantsCAN NOTprocess phosphorus like other plant . rather , this mineral can be toxic to your hibiscus .
Phosphorus can get added into the soil through fertiliser or even the water used for lachrymation . A plant with too much P is not recoverable !
