Whether you ’ve spent weeks hold off for your avocado seed to shoot , or you just convey home a little plant from the nursery , it can be dishearten to see the foliage curling , becoming juiceless , and peradventure even dropping off the plant .
Your first instinct might be to reach for the watering can – but look ! There are several reasons why your avocado industrial plant ’s leaves might be curl , and with a minute of know - how , you ’ll be able to spot the effort and fix the trouble easily .
abject humidity and underwatering are the most common causes of avocado leaves curl . Root bunk is another possible cause of this issue . With too much water , the roots get damaged and the plant finally drowns . The leaves get no piss from the damage stem , curve up then drop off .
In this article , I ’ll take you through this and the other causes of leaf curl in avocado plants . You ’re indisputable to discover the resolution to your plant ’s job !

Causes of Avocado Leaves Curling
Under Watering
Probably the simplest explanation for curling leaves on your avocado works is lack of water . If the leaves are curling downwards , drooping , or look crispy , this could be the reasonableness .
Avocados are subtropical plant and like a humid environment with plenty of water , and it is important to keep their grease well - draining , consistently moist but not blind drunk .
If they do n’t get enough water system the cells in their leaves begin to collapse , causing the curling force .
However , under lacrimation is not the most common intellect for curling leaves on avocado flora , so hold off before you douse your plant !
Overfeeding with Fertilizer
To thrive , avocado plants need a mixing of nitrogen , potassium , Mg , and phosphorus as well as touch amount of other mineral .
Feeding your alligator pear works regularly will secure it gets the nutrient it needs , but check that you do n’t give your plant too much solid food !
Avocado plant that receive too much fertilizer will develop rickety growth and limp , yellowing folio , sometimes with brown top .
The mineral in the fertiliser build up in the soil and cause radical burn , which stops the plants ’ stem from work properly and get these upshot .
It is important to decent adulterate the industrial plant food using the instruction on the packet , as using too much will lead to over - fertilization .
Avocado plants do n’t need a peculiar type of fertiliser and are glad with a ecumenical - role 20 - 20 - 20 houseplant solid food .
Lack of Nutrition
Nutrient want in plants can show themselves in many different manner , and kink leaves is one of them .
Potted plants are in particular prostrate to alimental deficiencies as they only have approach to a very limited amount of farm average .
Over fourth dimension , nutrients in the soil become depleted as the plant uses them , and physical process that would naturally replenish nutrients do n’t happen . Nitrogen is responsible for the better growth of plants ’ vegetative part like leaves , so if there is any want of this vital nutrient flora may show it by curling the leaves .
If you ’ve had your flora for a while , watched it grow , and never fed it , prospect are it will apprise a feed !

Temperature Stress
Avocado plants prefer an environmental temperature of 60 – 85 ° F ( 15 - 30 ° light speed ) and will show signs of hurt if keep in a cold or warmer situation .
In cold-blooded temperatures , the flora ’s systems ca n’t function properly and the plant may go dormant or in very insensate temperatures it could die .
In very hot temperature the plant is ineffectual to make do on a cellular level and the plant life ’s cells will begin to collapse in the heat .
If you ’ve of late moved your avocado flora to a fresh location then notice its leave begin to curl , it could be hurt from temperature strain .
Moving from indoors to outdoors or frailty versa , or even a move to a different part of the house can stimulate temperature stress .
In extreme cases , this can make the works to drop all its parting , and although the problem is not commonly so stark it is important to take measures against temperature stress .
Root Rot from Overwatering
Overwatering is a killer for houseplants , include avocado tree . It produces symptom similar to those of under watering , often propel another lacrimation – worsening the issue .
If a plant ’s tooth root are surround by water so that melody ca n’t get to them , they suffocate and die .
These idle roots can then become infected with antecedent rot which can spread to the sound roots .
finally , this will show in the leaves of the plant as the cells ca n’t pick up enough moisture from the roots .
Consequently , the leaves will not get the nutrients and water that it needs . Leaves will draw in as a defence mechanics to save water and other resources . The job will vote down the industrial plant unless treated .
Water Quality
water faucet water incorporate substances that can work up up in the compost of container plants , causing a variety of problems including curling leave .
When these substances are in too high quantities they can cauterise flora root and cause a lot of damage .
This is a special problem in country with heavy body of water , which contains a higher dimension of mineral .
The minerals from the wiretap water construct up in the territory of container plants , causing similar job to those of over - fertilization .
water tap water contains chloride and fluoride . Which are meant to kill all kinds of microbe .
It can also kill the good microbes within the stain . Microbes are essential to make the nutrients available for the works .
If the roots are not getting nutrients they will show symptoms like curve parting .

Too Much Direct Sunlight
If your avocado works is on a sunny windowsill and you ’ve find the leaf beginning to curl , it ’s probably get too much sun and starting to burn !
Although avocados love the Lord’s Day , the direct irradiation intensified by the chalk of a window can be too much , especially for young plants .
The strong sunlight make the industrial plant to lose water from its leave of absence chop-chop , and to protect itself the plant life curls up its leave to take down the surface area exposed to the sunlight . You may also findbrown spotsdue to exuberant Sunday exposure .
I have written an articleon drive and solution of brown spots on avocado leaves , it will suffice all the possibles questions you might have .
Lack of Light
Avocado plants need a lot of light to thrive . If you see your plant develop towards the window , or folio in the saturnine sphere curl up and conk , you need to move your flora !
When growing in their born environs , young avocado pear plant develop in partial shade from old Sir Herbert Beerbohm Tree and are unremarkably felicitous in collateral light .
As the flora get on , their cells become toughened and more able to tolerate strong , lineal sunlight .
Diseases
Fungal infections are the primary disease threat to container - spring avocado plants .
Root rot is a case of fungous disease that can first show itself in wave parting that look as if they necessitate water .
As the roots rot , they become unable to fall water up the plant get dehydration symptoms .
Other types of fungal disease such as powdery mould can also affect avocado plant , with bad case make leaves to curl and pop off off .
Persea Americana Sir Herbert Beerbohm Tree can also be affected by cankers which cause ‘ sores ’ on the bark of the tree , and a disease called sunblotch which causes discolor , distorted growth .
Insect Infestation
Avocado plant observe outside are more probable to fall prey to insect infestation than those kept indoors .
Avocados can come down quarry to several works piranha admit :
These insects make harm to the plant life either by seize themselves to the leaves and sucking out the succus of the leave . Insects like mites and scale munch through the leave-taking as a cat does .
Low Humidity
Perhaps the least obvious causal agent of leafage curl and one of the most rough-cut for housebound avocado plants !
A want of moisture in the air essentially dehydrate the plants – sucking the H2O out of them . The leaf start to curl before eventually turning brown and fall off .
downcast humidity can kill plant very quickly so it is crucial to take action as presently as possible !
Avocado plants like a humidity stratum of around 70 – 80 percent , but can tolerate levels down to 45 % .
Avocado Plant Leaves Curling After Repotting
Sometimes repotting a works goes incorrect . Maybe you dropped the plant or circumstantially broke off some of its roots , or maybe you used the wrong potting medium .
If you notice that the leaves of your avocado plant are curve after repotting , retrieve about how you repotted it .
If the plant receive a daze like losing some roots this will often show as dropping leaves .
The good tidings is that unless the shock absorber was too tough , the plant life will probably recover if treated cautiously .
When your industrial plant did n’t have a shock during repotting , think about the potful and potting medium you ’ve used .
If it is too heavy , lactating , or compacted this could be causing your plant problems . When the hatful is too big , this can encourage root rot .
