Why is the parsley plant turning white?

Parsley Plant Turning White

So you’ve observed your parsley plant slowly changing color and turning white. This has alarmed you and you decided to search up why this may be happening.

Sounds somewhat like your story? Well, parsley plant leaves turning white can occur due to a variety of reasons. 

It may range from something as simple as a bit more sunshine and water to major plant disease. Whatever may be the case, you need to pinpoint in first before you take action.

Or else, you may find yourself slapping a bandaid on a concussion and calling it a day! 

So let’s take a look at the common reasons and solutions behind your parsley plant turning white.

Factor 1: The plant can’t produce chlorophyll

We all are familiar with what makes plants green. In case you don’t want to recall your 3rd-grade science teacher, let us give you a quick recap.

Chlorophyll is a green pigment which helps plants sustain their life. This happens through photosynthesis, where sun rays are used to create food for the plants. 

Now imagine what happens when a plant cannot produce this green pigment chlorophyll for some reason! Yepp, a surefire and slow way to die.

Sometimes, plants are hit with a condition called chlorosis. This affects the plant’s ability to create the green pigment and thus the whole system collapses from inside. 

If your plant has been affected, then recovery is a difficult process. The best thing here is to prevent the problem before it occurs. Let’s see how.

Solution 1: Preventing and treating chlorosis

One of the most common reasons for chlorosis is iron deficiency in plants. If this is the case, then the only way to amend this is to use fertilizers rich in sulfur and iron sulfate.

Make sure you do so in moderation. The last thing you’ll want is to create another issue for your plant by over-fertilizing.

Other than iron deficiency, chlorosis can also be caused by waterlogging or damaged roots. So make sure that you don’t overwater your parsley and you’ll be good to go.

Factor 2: The plant is affected by bacteria

If it’s not chlorosis, the parsley plant may also be affected by bacteria. Now you might be wondering how would you know this?

Even if you’re not an expert gardener, you’ll be able to notice some telltale signs of a bacterial infection. 

If you notice white spots on parsley leaves, then it’s almost always a bacterial or fungal infection. 

If the bacterial infection is in the initial stages, you’ll notice some slight discoloration. But as it progresses, the parsley plant may even die off. 

Here’s how you can fix this.

Solution 2: Treating bacterial infection on plants.

Bacteria like to grow in humid warm conditions. So try not to let water sit on the leaves and stems for too long. 

Also, remember to water only the roots. If you splash water all over the stems and leaves of the plant, then it may take a super long time to dry. 

Moreover, if you keep your plants indoors, then try ensuring that it is in a well-ventilated room where the plant gets enough fresh air.

Or you could shift the plants on the balcony in the morning for it to get some refreshing morning rays. However, do this with caution since moving your plants too much could cause root damage.

Other than tackling a humid condition, try using the best quality seeds to grow your parsley. Today, you’ll find loads of disease-resistant breeds on the market. Although a bit more expensive, these are usually a safe bet.

Factor 3: The plant isn’t watered properly

Last but not the least, your watering habits may be a little off. This might cause your parsley plants to wither and slowly turn white.

Now you may already know this, but water and sunshine are two basic pillars when it comes to growing a healthy plant. If you mess up on these two areas, it won’t matter how rich the soil is or how great the seeds were.

Here’s some advice on how to water the plants properly.

Solution 3: Watering the parsley plant properly

Now if you have a hard time remembering to water your plants, you may be tempted to create a schedule. 

But if you water the parsley plant when it doesn’t need it, it’s of no use.

So always do a soil test by inserting your finger in the soil. If it’s dry, then water it. Or else, you can skip watering for that day.

Remember that overwatering parsley is also as bad as underwatering it. If you pour excess water on the roots, it may cause them to decay and die off. This is also a major reason for the curly parsley plant turning yellow.
