Common Grevillea Cream Pests and Diseases to Watch Out For

Scale

Scale issues are bound to arise in areas where Grevillea Peaches or Cream is present. This is a common pest to the shrub. They eat the sap of the plant and leave behind a sticky substance.

It’s this stickiness that then causes sooty mould to develop, a black fungus which can then actually harm your plant. To get rid of scale, rub the leaves with your fingers. 

Once you’ve done this, you can then spray your Grevillea Peaches and Cream with something like neem oil which will help to get rid of any leftover scale. It will also take care of the sooty mold once you have removed the scale insects. 

Root rot

You’ll know you’re dealing with root rot if the roots of your shrub are soft and brown instead of strong and white. This happens when the soil is too wet.

This is a great place to grow fungal spores. They spread quickly and take over roots. Root rot means that the plant won’t be able to absorb nutrients and you start to notice the leaves will wilt and become yellow.

They may even begin to fall off. If you’re dealing with a really severe case of root rot, it’s possible for the plant to die within 2 weeks. If you’ve diagnosed the problem as root rot, you’ll need to make a call about the plant and whether it can make it. 

If the whole of the root system is soft and squishy it’s unfortunately too late. There is still hope if you find white spots on the roots. The shrub can be replanted in new soil. Make sure it has good drainage.

You’ll first need to prepare the plant by cleaning the roots in running water. You will need to remove any brown or squishy roots using scissors. Then, replant as soon possible. After the process, sterilize your scissors. 

Mealybugs

Mealybugs are tiny insects that look a little like cotton on plants’ stems and leaves. Like scales, they suck sap out of the plant tissue but don’t cause too much damage if the infestation is minimal.

If you’re dealing with a big infestation, you might notice that the leaves turn yellow and start to curl. Meatybugs leave behind a sticky substance that can cause sooty mould. 

You can trim off any affected parts of the plant and use rubbing aloe to clean the leaves. Neem oil is a great oil to useBecause it affects the growth and development in mealybugs, and is also kind to the environment.
