Blackberry Leaves Turning Brown: Explanation and Remedy

The blackberry leaves can turn brown for a number of reasons. So, in order to solve the problem, you must first identify the main issue. It goes for every plant that has browning leaves

And to do that you need to identify the main reason for brown blueberry leaves. So, here we provided all the reasons for which you might be facing this problem.

Let’s walk through all the issues so that you can figure out what went wrong in your case.

Reason 1: Infiltration of Fungus

One of the primary reasons for blueberry leaves turning brown is due to fungus attack. Those pesky little creatures can crawl through your garden destroying your leaves.

Moreover, since they have no other place to call home, they’ll always come back to haunt your garden. And in the worst-case scenario, they borrow some life energy from your blueberry plant.

When they do that, your plant will start getting weak. Until eventually they can’t bear it anymore and scream out for help.

Now, obviously, they can’t shout like us so they’ll signal you in their own language. In this case, they will turn brown so that you take notice.

And once this catches your eyes you must take immediate action. Fungus attack like these can cause several other plants to turn brown.

Solution:  How to Remove Fungus from Blackberry Leaves?

To remove the fungus, you must first identify which leaves have been damaged the most. You can judge this by seeing how much brown they have turned.

The ones that are dark brown cannot be saved. And thus they must be removed at once with the help of a pruner. Once you take care of all the lost cases you must move on to phase 2.

That is, you have to apply water at high pressure to force the fungus to leave. For this use a water hose. But be careful, you don’t want the pressure to be too high.

That can damage the plant altogether. And once that’s over you can add in some fungicide to kill off the remaining fungus.

Reason 2: An Overdose of Water

Another reason for the brown leaves is excess water. You see while carrying out your gardening responsibilities you might get carried away and pour too much water.

And that can cause the plant to take in more water than it can hold. Now, while other plants puff up and go greener the blueberry leaves react in a different way.

And yes, you guessed it. They turn brown. Which is definitely not a good thing. So, you might want to avoid that.

Solution: How to Ensure the Correct Amount of Water for Blackberry Plants?

Now this problem is very easy to tackle. All you have to do is make sure you don’t pour too much water. Yellowing and browning both can be side effects of overwatering. 

To keep this habit in check only water the plants when the soil is dry. You can easily notice this by looking at the soil.

However, if you’re still not sure then stick in a toothpick to see if the soil is moist or dry. That will help you decide if it’s hydration time for the plant or not. Moreover, you can use an indoor planter with drainage

Reason 3: Too Much Potassium in Fertilization

One more reason for blueberry leaves turning brown is too much potassium in the fertilizer. You see, if you go apply the right fertilizer to the soil then you might be in danger.

That’s because the blueberry plants will get too much food and get nauseated. This reflects in their leaves which will turn brown at the end of the day.

Solution: How to Input the Right Fertilizer?

So, to avoid this issue you must buy a fertilizer with the right amount of potassium. And there are a lot of them available online.

You can surf the internet and get the one that will suit your plant the best.

Reason 4: A Blast of Heat

Another possible explanation for your brown colored blueberry leaves is too much heat. You see, too much exposure to the sun can cause sunburn to the blueberry plants.

While our body gets tanned the blueberry leaves turn brown.

Solution: How to Subdue the Heat?

In order to prevent sunburn from your blueberry leaves, you can place the plant in a shady place. Or buy a roll-up blind that’ll prevent direct sunlight from reaching your plant.

This way your sun can bathe in the sunlight without the fear of burning itself. And while it enjoys its soothing bath you can live a worry-free life.

Then you’ll be able to treat the problem accordingly. Nevertheless, we hope this guide helped you in your case. But if you have more questions simply leave a comment.
