Overwatering, which causes root rot, is the primary cause of bottlebrush plant death. A lack of iron might also cause your bottlebrush plant to die.

Bottlebrush is an Australian native plant. The plant is cultivated in gardens for its unusual but attractive red blossoms. Another name for the bottlebrush plant is Callistemon.

The blossoms are what give the plant its name. The flower has a bottle brush cleaner-like appearance. You can easily buy this plant online and grow it quickly. The plant does experience problems. Let’s examine the issues and potential solutions.

What Is Causing the Yellowing of Bottlebrush?

Because of inadequate irrigation and iron chlorosis, bottlebrush leaves turn yellow. A significant-scale infestation would also cause bottlebrush leaves to turn yellow. Another factor contributing to Bottlebrush foliage turning yellow is compacted soil.

Iron Chlorosis

Iron deficiency in the soil causes the growth of chlorophyll-free leaves. Iron chlorosis is the name of this illness in Callistemon. Yellow and dry leaves change colour. The demise of the branches and stems comes next. Both improper watering and compacted soil might result in iron chlorosis.

Improper watering

Do you properly water your bottlebrush plant? The most important outside component that impacts a plant’s health is water. If enough water is available, plants benefit from it. It poses an issue of whether there is too much or not enough.

The plant will display excessive hydration through its leaves. The leaves gradually turn yellow and become limp and mushy. Root rot can also be caused by overwatering. Only water the plant when it requests it. If unsure, you can use your fingertips to feel the soil. Only water until the first two to three inches of soil feel dry.

Similar symptoms are also caused by underwatering. The leaves dry up yet turn yellow.

How to Fix it

You might need to water your Callistemon trees once a week if they are young. Bottlebrush plants are avid water consumers.

Water the plant gradually to allow deeper roots to receive some liquid. Add a 2-inch layer of organic mulch to help reduce water evaporation.

Bottlebrush Leaves Curling

Verticillium wilt disease is mostly to blame for the curled leaves of the bottlebrush. The leaves exhibit irregularities and discolouration before turning yellow or brown.

Verticillium wilt

A fungus called verticillium wilt infects a plant through the roots and spreads to the stem. On the way, it creates destruction. The infection changes the shape and colour of the leaves as it spreads through the vascular system. Curled and yellow/brown leaves develop.

Cutting the affected leaves and examining them is the most effective technique to determine if they are afflicted with Verticillium wilt. If the plant is diseased, dark circles will be visible in the cross-section.

To Fix:

By taking good care of the plant, try to strengthen its resistance. On schedule, give the plant water and food. 

The second option is to dispose of the plant safely. In that location, avoid planting anything vulnerable to Verticillium wilt.

Bottlebrush Scale

The Callistemon leaves will also turn yellow if there is a severe scale infestation. On the impacted leaves, yellow dots are initially visible.

Scales used for armour are pretty small—about 1/8 inch. On the plant’s stems and leaves, they collect in groups.

These scales consume the sap found in the stems and leaves. As they finish the sap, they distort and make the leaf yellow.

The leaves shrivel up and die. Branches of the plant eventually get brown and burned if the infestation is not under control.

To Treat:

As soon as you notice the impacted branches, prune them. When the infestation first begins, this aids in controlling it.

Scale infections can be detected early by placing sticky cards around the afflicted plant.

Scale larvae that are crawling appear as orange-yellow flecks. Apply horticultural oil to the plant after you’ve identified it.

For effective scale eradication, you might need to spray the diseased plant numerous times with 10-day pauses between applications.


The bottlebrush plant is resilient. Only when you buy this plant online, and proper care isn’t given, can issues occur. The main cause of bottlebrush trees’ problems is improper irrigation. Therefore, you must ensure that the tree receives the right water.

Ensure that the soil drains excess water effectively. Regularly inspect the tree for any insect infestations. If you detect such a pest, you should treat the tree.
