4 Reasons Your Rose Of Sharon Has Yellow Leaves

If your Rose of Sharon’s leaves are turning yellow, it could be due to one of the following reasons:

  • 1. Lack of nutrients in the soil
  • 2. pH of the soil is too high or too low
  • 3. Soil is too dry or too wet
  • 4. Plant is stressed

Let’s take a look at the reasons for these problems and the steps you can take to resolve them!

#1: Lack Of Nutrients

Topping the list of reasons for yellow leaves is a lack of nutrients.

This can be due to several different factors:

  • The soil is too sandy and doesn’t hold onto nutrients well.
  • You haven’t fertilized your plant in a while.
  • The roots are bound and need more room to grow.

Your first step is to determine which of these factors might be causing the lack of nutrition in your Rose of Sharon

You can amend the soil with compost or other organic matter if it is too sandy. This will help the soil hold onto nutrients better.

Look at your plant’s leaves to tell if you need a stronger soil amendment. If they are pale green or yellow, then it is likely that your Rose of Sharon is lacking in nitrogen.

On the other hand, if the leaves are dark green but with yellow edges, this is a sign of too much phosphorus.

Now is the time to do it if you haven’t fertilized your plant yet. Use a fertilizer that is high in nitrogen, phosphorus, and potassium.

If you think your plant has too much of one nutrient and not enough of the other, you can get a specifically tailored fertilizer for Rose of Sharon.

The last possible reason for the lack of nutrients is that the roots are bound. This happens when the plant doesn’t have enough space to grow.

As a result, the roots will start to circle around themselves, which prevents them from getting the nutrition they need.

To fix this problem, you will need to transplant your Rose of Sharon to a larger pot or area in the ground.

When you do this, loosen up the roots so they can spread out.

#2: pH Of The Soil Is Too High Or Too Low

Another possible reason for Rose of Sharon’s yellow leaves is that the pH of the soil is too high or too low.

If the pH is too high, the soil is too alkaline. This can be caused by things like limestone in the soil or too much fertilizer.

On the other hand, if the pH is too low, it means the soil is too acidic. This can be caused by rainwater or mulch made from pine needles.

To raise the pH of the soil, you can add lime or wood ashes.

Once you know the pH of the soil, you can take the necessary steps to adjust it.
