The genusLantanais one of the more pop ones in theVerbenaceaefamily , and its 150 or so plants have often been referred to as shrub verdanas .
In area with warmer climates , lantanas can be cultivated as perennials , while in colder climate , they are grown as yearly .
Lantana plants are comparatively easyto like for and can have very heavy foliage and blooms .
But loose to care for does n’t inevitably intend foolproof , and there are multiplication your lantana will get crazy .
One cardinal sign of illness is curling leaves , and often , the counseling of the curl ( upwards or downwards , AKA wilting ) can tell you a lot about what ’s wrong .
If you ’re experience curled leaves , do n’t panic . Diagnosing the problem can usually lead to your lantana being glad and good for you again .
Why is My Lantana Leaves Curling?
Your lantana could have curling leaves for several reason , usually related to alimentation ( yellow leaves ) , tutelage , or an infestation or contagion .
Here are the most common reasons , how to diagnose them , and how to treat them .
Heat and Sunlight
Too much of a good thing is n’t good . For example , direct sunshine or too much heat can cause leave to curl upwards on Lantanas develop indoors .
In the case of full sun , you might see signboard of scorch on older leaves and stunted emergence on younger ones .
In the case of heat , your flora ’s leaves are curling up to preserve their piss , which is mainly sweat out to elevate local humidity .
In both cases , seek to provide your plant some more shade by moving it to a spot with bright , collateral sun or by placing some good afternoon shade over an outdoor plant .
Six hours of direct sun per day is enough for the lantana .
Herbicidal Poisoning
If you prefer using green goddess orca over deal - pick or complimentary horticulture , your lantana may have accidentally suffered chemical burns .
This can easily pass off if you spray too tight to the flora or if a breeze clean up droplets .
up - curving leaf are often the first symptom , and if you see this within a day or two of using an weedkiller , you ’ll need to hose down down the plant to get any chemicals off .
Once unclouded of chemicals , give the plant life some fertilizer to help it recover , and note that any existing damage may have to be pruned away .
To battle perniciousness from excessive fertilizer or Strategic Arms Limitation Talks buildup , thoroughly flush the dirt around the lantana plant with piddle to remove the problematic substances from its antecedent zone .
Infections
Your plant ’s leaves will often coil when it ’s suffering from an infection , with an upwards curl usually diagnostic of a viral infection and a droop or downwardly curl being the result of many fungal infections like sooty mould .
There ’s a upright chance you ’ll also see other symptoms , such as discolorations , blister , or unnatural emergence .
In fungous disease , a antimycotic or ( depending on the fungi ) neem handling will help .
Neem foliar spray can combat many surface fungi , while the soil soak can combat kingdom Fungi that break through the plant ’s surface .
alas , viral infections are often far more spartan , and many are incurable .
In such face , you may have to sacrifice the entire plant , although sometimes you could safely rationalise away infect stems before the disease disperse .
Note that you will also need to check out any nearby plants for signs of infection .
Infestations
There are a luck of nasty small vampire out there that sexual love chewing on plant share .
Aphids , lacing hemipterous insect , mealybugs , whiteflies , and spider mites are vulgar pests that can invade lantana works .
This can lead in the leaf drop or leaves curling up as they ’re drained .
Infestations wo n’t usually kill your lantana but can lead to secondary infections or circularise to other plants .
You ’ll usually be able-bodied to spot the bug on the bottom of leaf .
handling is generally middling easy using insecticidal soap made from neem oil colour , either as a foliar spraying or , preferably , as a dirt soak .
Note that theneem soak ask longerto show its effect than the spray , but one Lucy in the sky with diamonds protect your plants for up to 22 solar day , and it can be used every 2 to 3 weeks as a non - toxic hindrance .
Also , consider attracting beneficial insects like butterflies , bee , and hummingbird to help keep pest population at bay .
Malnutrition
plant demand several food to grow properly .
Nitrogen is one of the Big Three , and a deficiency can cause the older parting to curl upwards as the flora airt its available nitrogen to the new growth .
Meanwhile , cop , iron , phosphorus , and potassium insufficiency can result in the leaves curve downward or drooping .
Ensure the fertilizer you ’re using has the right NPK contentedness and that you ’re feeding the flora concord to the package instructions .
A grunge test will give a balk of the nutrient levels .
solve this problem is often as easy as adding compost , changing the plant food , or how often you feed the lantana , or using an branding iron or copper supplement .
Poor Lantana Watering Habits
One of the few things that can vote out your plant is that excess water system will lead to theme putrefaction , and often , your first symptom is the leave curling upwards .
ascendant rot is a serious precondition that can be treated if caught early enough but pestilent if ignored .
Meanwhile , a down drooping and possibly brittle texture is a planetary house of underwatering .
Avoid both conditions : too much body of water or underwatering with thesoak - and - ironic method acting of watering .
Lantanas require moderate irrigation and prefer moist , well - drain soil .
only put , apply your finger to try out the sobriety of the soil and only water when it ’s dry about 1″ to 2 ” inch down .
Ground - based plant life should be watered when the soil is dry to the contact , as they usually have good drain than those in container .
Always water slowly until you see the H2O start to ooze from the drain holes ( or enough on - land plant to be 1 ” inch per calendar week after accounting for rainfall ) . water supply lantana from the priming level during the morning hours .
Note that in severe cases of overwatering where the soil is soggy , you may also necessitate to transfer the lantana to a fresh good deal of soil , snip away any diseased roots in the process .
Regularly audit the soil wet level and adjust your watering relative frequency consequently .
Drought
Another cistron for curling leaves can be because of drought seasons .
Lantana camara is known for being drouth - tolerant plant , but prolonged periods of drought can still affect its health .
Regular tearing is necessary to maintain drought tolerance and prevent leafage curling .
