Rose of Sharon Problems – Dealing With Common Althea Plant Issues
What Is Eating My Rose Of Sharon Leaves?
The first thing to do when your roses are showing signs of death is to get them out of danger. The second step is to figure out what’s causing the problem so you can fix it. That’s where a professional comes in! A professional will take care of all the details and make sure everything goes smoothly.
Aphid infestation is one of the most common causes of death for roses. There are many different types of aphids, but they all have one thing in common: They love to feed on the sap from the plant’s roots. When these tiny insects suck up sap, they cause damage to the stem and leaves. You may not even notice any symptoms at first because you’re too busy enjoying your flowers or eating them raw (or sometimes both). But eventually the damage becomes apparent.
It’s possible that your roses were infected with some other type of fungus, which would explain why they didn’t show any symptoms until now. If you suspect something else is going on, then you’ll need to consult a professional. Your best bet is to contact a nursery or grower who specializes in roses and ask them how they handle such problems. Many nurseries offer free consultations and will do their best to diagnose the issue and suggest solutions.
You may find evidence that your rose of sharon is experiencing root rot from aphids. While the presence of aphids doesn’t always mean root rot, this is a common sign along with wilting leaves, yellow leaves and stunted growth. This is caused by a variety of factors that all have to do with the rose’s environment, but it’s much easier to just pinpoint the problem as aphid infestation if you suspect they’re the issue.
If you don’t know what’s eating your rose of sharon leaves, then the first thing you should do is take a personal inventory.
Do you or anyone in your household have a health condition that would prevent you from taking care of a rose?
If so, then it may be best to just get rid of the plant. If everyone in the house is healthy, then it’s time to look at the plant’s environment.
The first thing you should do is check the soil.
Is it dry, wet or just right?
Roses need well draining soil that isn’t too dry or too wet. You can buy special soils at many garden centers and most nurseries, but it’s also fine to use a simple garden soil as long as you mix in a bit of sand to improve drainage. Water the soil, not the plant, and water it enough that drips come out of the bottom of the pot.
Next, pull the plant out of the pot. If your rose of sharon has a mushy middle or appears to have “tummy trouble,” then it probably has root rot from too much moisture. To fix this problem, you’ll need to trim away all of the rotten roots and repot the plant in fresh soil mixed with sand or perlite.
Did You Know?
The first thing most people think of when they hear rose of sharon is a flower.
But did you know the name also applies to trees in the Magnolia family?
The flowers are smaller on these varieties and offer a wide range of colors, but they are just as fragrant.
Your other option is to stop using soil altogether. There are several types of soilless mixes that offer the benefits of well draining and moisture retention but without the heavy potting soil that is prone to rotting roots. Perlite is one option, as is sand and a additive like coco peat or worm castings. These are typically lighter than regular soil and often come in large bags, which makes them easy to work with.
Finally, inspect the leaves for signs of insects. If you keep finding them on the plant, you may have an infestation that needs to be taken care of with an insecticide. Otherwise, just keep an eye on the leaves for signs of damage and treat accordingly.
