Why your parsley may be turning red?

Parsley Leaves Turning Red

Now anything from over watering your plant to not taking enough care of it could be the cause behind your plants suddenly turning red.

Although it may seem like the reason is simple, any experienced gardener would tell you that there is more to it. So let’s take a look at the various causes one by one. 

That way, you will hopefully be able to identify what you may be doing wrong and correct it right away!

Reason 1: Direct harsh sunlight

One of the most common reasons for parsley leaves turning red is too much exposure to sunlight.

Now although all plants need a healthy dose of sunshine, some herbs are too delicate to receive direct harsh afternoon sun.

So if you’ve kept your potted plant super close to the window, it may be exposed to direct afternoon sun. This may be why the parsley leaves are turning red.

How to combat it?

You can prevent your parsley plant from burning under sunlight by relocating it to a cooler corner of the home.

We’re not asking you to find the darkest spot. A place where the plant can receive indirect sunlight but stay protected from the afternoon sun is perfect!

If that’s not possible, or you keep your potted plants in the balcony, then just shift the plant during the afternoon.

Reason 2: Overwatering/ under watering 

It’s said that too much love or too little love can ruin just about anything, and your little parsley plant is no exception. Other than red, this could also prevent your parsley leaves from turning yellow .

If you are watering your plants too much, there may be water logging or the soil will always be super damp. This may cause parsley plant leaves turning red .

This may cause the roots to start rotting. Also, the plant won’t be able to absorb all the necessary ingredients from the soil, which will cause the plant to die off slowly.

In the case of underwatering, things are a little different. The roots will start dying off when the leaves no longer have moisture in them. Extra dry soil will also make it impossible for the roots to absorb nutrients from the soil.

How to combat it?

If you notice that your watering habits have been a little off lately, don’t worry. This is something that can easily be fixed. Here’s what you’ll need to do in both situations.

Overwatering

In case you’re overwatering your parsley plant, leave it alone for a few days. This will give a break to your plant and it will be able to absorb all the excess water.

To aid this process, keep it under the early morning sunlight. This is gentle yet a powerful aid to help your plants grow. 

After the soil has dried a bit, scoop the top layer of the soil and check for any rotted roots. If you find them, then clip off these roots and throw them away.

Afterward, you can shift the plant to a new pot with new soil for a fresh start.

Underwatering

But if underwatering is the case, then fix a schedule to water your plant every day. You can set an alarm on your phone to remind you.

Just make sure that you give enough time for the soil to dry in between the sessions.

Reason 3: Too small pot

Last but not the least, your plant may be dying off because it doesn’t have room to grow.

If there isn’t much depth to the pot, there isn’t going to be enough soil when the plant grows beyond a certain limit. 

This will not allow the roots to grow any further and your plant won’t be able to grow to its full potential. So this is a problem you must fix asap if you don’t want your plant to die off.

How to combat it?

If the pot is too small for your parsley plant, the only solution is to repot it into a bigger pot. But be careful!

If you mess up and break the roots while repotting, you could potentially kill off your plant.

Just carefully remove the top layer of soil and turn the pot to one side. Then slowly pull the pot away from the plant while supporting the stems.

Remember to never pull the stem from the pot. Always pull the pot. You could also water the plants beforehand to make the soil loose and this process easier.
