Caring for these bushes is very easy as they are hardy and comparatively drought resistant plants. They are medium-sized bushes and produce flowers that look like a bottle brush, hence the name. The flowers are generally red in color, but some can also be seen in colors like white, yellow, orange, green, as well as cream. They are hardy to USDA zones 9 through 11.

You need to plant a tree in an area that receives partial to full sun. This will help ensure full blooms and good growth. The soil should be well-drained and the sapling should be planted in spring or summer. Tree cuttings are also useful in propagation of this plant. Make sure you do not plant any other plant within 5 feet of the bottle brush. This is because it tends to grow a lot and expands easily.
Add a low-phosphorus 10-5-10 fertilizer in spring or fall. This will help the plant absorb nutrients for better growth. It is always a good idea to carry out mulching at the plant's base. This helps retain moisture, avoid weeds, and keep away diseases. Apart from regular rainfall, it does not require a lot of watering. However, in hot and dry conditions, make sure you water the plant regularly.
Pruning the plant not only helps control the height of the plant, but also ensures new blooms. The flowers tend to bloom on the new growth of the plant. Pruning is best undertaken in spring. It is a good idea to cut back about 2 to 3 inches into the branches. If you see a strong bud, prune the branch slightly above it. You can even prune the tips of the bush. This will help you shape your plant and also encourage branching. You can cut the older branches in spring as they have fewer flower growths. Removing these will also help new growth in the plant. You can cut back the older branches, outward facing shoots, etc. Lower branches too should be pruned.
