White spots on snake plant leaves can be puzzling. Get the answers and top snake plant care tips to restore your plant’s natural beauty.
Have you noticed white spots on your snake plant’s leaves? While this can be a bit alarming, don’t worry – it’s not always a cause for panic.
We’re here to help you figure out what these white patches are and how to deal with them.
What are the White Spots on Snake Plant?
Pest infestation is one of the most frequent reasons for white spots on snake plants.
In particular, bugs that prefer to feast on the succulent leaves of your snake plant and draw in sap.
Mealybugs are a common culprit.
These white, fluffy insects resemble tiny cotton clumps on your snake plants.
They resemble ancient insects up close, with a strong armor-like shell. Their bodies are covered with white fluff, giving them the appearance of white spots on snake plant leaves.
They will frequently gather on the undersides of the leaves of your snake plant.
But, due to a room shortage, colonies that develop into pest infestations will migrate to the upper side of the leaves.
2. Spider mites
Another pest to watch out for is spider mites. They come in a variety of hues, including red, brown, and, you guessed it – white.
Although smaller and trickier to spot than mealybugs, they weave fine webs on the leaves, which can appear as white specks from afar.
Just like mealybugs, spider mites are sap-lovers and can quickly become a problem if they infest your plant.
Plus, they’re not picky – they’ll happily move on to other nearby plants.
How to Get Your Snake Plant Free of Pests?
We recommend giving your plant a good shower with a pressurized hose.
The thick, fleshy leaves allow them to withstand significant pressure, so removing white spots on snake plants will be really easy!
Focus on the undersides and tops of the leaves to make sure you’re thorough.
To be extra sure, follow up with an organic insecticide. Natural oils work well to target any spider mites that might have escaped the pressurized hose attack.
3. White Spots Caused by Hard Water
Sometimes, it’s not pests but hard water causing those white spots on snake plant.
When water passes through layers of minerals such as gypsum or limestone, hard water is created.
High concentrations of minerals are achieved when the water gradually absorbs the minerals from the sediment.
It’s commonly provided as tap water to suburban homes worldwide, including in the US and European cities.
When you water your plants with it, these minerals can accumulate on the leaves, leaving white residues as the water evaporates.
Do Diseases Lead to White Spots?
You might be wondering if diseases could be causing snake plants to have white spots.
Interestingly, pests and diseases often go hand-in-hand. If pests weaken your snake plant, it becomes more susceptible to various diseases.
Let’s explore some common ones:
1. Powdery mildew
Powdery mildew is a common fungal issue that can attack your snake plant, leaving white or gray fuzzy patches on the leaves.
If you look closely, you’ll see mycelium filaments – but don’t get too close, as breathing in the spores isn’t great for you.
In severe cases, this disease can cover your snake plant in white spots, weakening it to the point of mushiness and eventual death.
Like other fungal infections, powdery mildew is most prevalent in damp, stagnant environments with little to no direct sunshine.
2. White mold
This fungal problem shows up as either reddish-brown, sunken spots or white, web-like growth on your snake plant’s leaves.
It can seriously harm your plant’s health and even lead to its demise.
Often due to poor care, insect damage, or just the wrong environmental conditions, white mold starts from spores in the air.
These spores love wet conditions and can quickly become a serious threat to your plant.
3. Tap water
Believe it or not, the fluoride and salts in tap water can harm your snake plant.
These salts build up over time, causing white spots and potentially stunting growth. They can also encourage bacteria and fungal growth.
How to avoid it?
Watering the plant with filtered water is one of two ways you may prevent white spots on the snake plant or at least make them cease.
If that’s not possible, try this trick: leave a bucket of tap water out overnight. This lets excess salts settle at the bottom, making the water safer for your plant the next day.
Understanding the potential causes of white spots on your snake plant is key to preventing and treating them.
Whether it’s adjusting your watering habits or keeping an eye out for fungal diseases, a little care goes a long way in keeping your plant healthy and spot-free!
