Yucca plant leaves curling isn’t that serious of an issue overall, but this does mean there is something going on that shouldn’t be.
If you find your Yucca leaves curling, more often than not it is due to how you are taking care of this succulent.
And by care I mean you are not taking good care but rather not paying attention to what is going on with your Yucca plant.
So if this is happening to your succulent then here are a few reasons why.
Overwatering causing curly Yucca leaves
Yucca plants don’t really require that much water in general, less than most succulents by the way.
So it is actually pretty easy to overwater your Yucca if you’re new to this or just don’t know that they are pretty drought resistant.
You may already know that overwatering can and will cause rotting roots if done for long enough and that most certainly affects how the leaves grow, or don’t grow.
If your Yucca plant leaves start curling then one possible cause could be due to the roots being rotted if you have been overwatering or using low quality soil that doesn’t drain properly.
Use this fast draining soil instead.
If you think you have been overwatering then you can always move the soil out of the way and take a look at the roots.
If your Yucca plant roots are brown or mushy then you’ve got rot on your hands and this is the reason for your curling yucca leaves.
In this case the damage to the leaves is permanent but you can always grow new leaves, provided that you pull away all rotting roots and keep the healthy ones intact.
You will just have to prune the curled leaves away and wait for new growth once you have salvaged your Yucca.
Overwatering may also be the reason your Yucca plant leaves turn brown as well if you have that going on I would check it out.
Low light causing curly Yucca leaves
Another special thing about Yucca plants is that they require more light than your average succulent.
You want to give them around 8 hours of full to partial sunlight daily for them to grow well and maintain themselves.
Once problem people have is that they either don’t allow their Yucca to get this much light or the light is not bright enough, especially when growing Yucca indoors.
When not enough light is provided, the Yucca plant leaves will start to curl and stretch in the direction closest to the source of light.
This appearance is also permanent but not really that bad in terms of your plant being at risk, more so just not cool looking aesthetically.
If you think your Yucca hasn’t been getting enough light then take a look at your conditions outdoors or if you’re growing indoors you should consider using a quality grow light.
Other than that just fix the lighting and prune the curled leaves and wait for new growth to occur.
Pests have taken over your Yucca Plant
Lastly and one of the not so common ways you can have curling Yucca leaves can be due to pests wrecking havoc on the succulent.
The main ones you have to watch out for are Aphids which will drain fluid from the leaves of your Yucca plant, leaving them dehydrated and dried out.
There are also other pests to watch out for such as Mealy bugs which can cause white spots on a Yucca which will also eat away at your plant.
This will most certainly cause your leaves to curl and generally be unhealthy.
If you notice these pests have taken control of your Yucca then you should use a pest spray designed specifically for these annoying intruders.
I recommend this neem oil spray by the way.
Do this on a consistent basis until you don’t see any more of them then monitor your Yucca succulent for some time after to make sure they don’t return.
Once this is taken care of you can prune the leaves if you choose to do so and wait for everything to return to normal.
