Bottlebrush or Callistemon plant holds its origin in Australia and Tasmania. It grows 3 to 4 meters tall and has gorgeous flowers. You can grow bottlebrush from cuttings – you will need some rooting powder, full sun, and regular hydration.
Bottlebrush is a perfect little tree for growing in your home garden due to the little care it needs and its vividly colorful flowers.
Bottlebrush is a member of Myrtaceae or the myrtle family. This family of plants is known for flowers that grow together in groups of four or five.
The most commonly known flower variety of bottlebrush is red. Bottlebrush flowers can also be white, pink, red, and green.
It came to Europe in the 18th century. It is a tough plant that can survive mostly easily in most types of soil.
Here are some worth knowing about Bottlebrush plant:
Hardiness Zone: 8-11
Best Season: Evergreen
Growth rate: Medium
Uses: Ornamental plant
Soil: fertile, well-drained, acidic to neutral
Growing Bottlebrush Cutting
To grow bottle bottlebrush from cutting, cut a branch 10 – 15 centimeters (6 inch) long. The branch should be semi-mature.
The best time to grow from a cutting is in summer. Prune off any branches, stems, flowers or leaves from the lower-half before planting. Dip the pruned end of the branch in a hormone rooting powder. You can buy a rooting hormone powder online or learn how to make one on your own here.
You will need to keep the branch cutting dipped in rooting hormone powder for six to ten weeks.
Keep the pot with the rooting powder and the potted branch in full sun and hydrated. Make sure the mixture gets neither too soggy nor too dry for rooting to be successful.
To know whether rooting has started or not, try pulling the stem out very lightly out of the rooting mixture. If the rooting mixture feels “bound” by the roots, rooting has happened. You can now move the rooted plant into soil.
Where do bottlebrush grow best?
Bottlebrushes grow best in hardiness zones 8 – 11. If you live in a zone outside it, it’s better to plant the bottlebrush in a pot that can be moved during harsh winters.
Plant your bottlebrush in a sunny spot. These plants are not too needy when it comes to soil as long as it is well-drained. The soil doesn’t need to be super fertile either, but you can add compost at the time of planting.
Once the bottlebrush survives the young age, it can even survive drought-conditions.
Taking Care of Bottlebrush and Maintenance
Bottlebrush is an outdoor plant that needs full sun and well-drained soil.
When bottlebrush plant is young, watering regularly is important, specifically in the dry season. Make sure the water saturates and penetrates deeply into the soil. For that, you could pour ample water slowly.
To prevent evaporation, add a 2-inch layer of sawdust, shredded leaves, or straw on the top of soil.
Pruning is usually not needed unless you want your tree to look a particular way.
Can bottlebrush tolerate pruning?
Yes, bottlebrush tolerates pruning easily. You can simply prune unwanted branches or shoots or to prevent too much vegetative growth.
Which pests can attack bottlebrush?
Bottlebrush is prone to scale, larvae, and caterpillar, but is resistant to most other types of pests.
Scales are particularly more common in bottlebrush and are also hard to spot. Scale can cause your plant leaves to have light-colored spots.
To prevent or to get rid of these on a small scale, you can use a simple neem oil spray. If they have impacted your plant heavily, you can purchase an insecticide from a store.
Can bottlebrush bear winters?
Most bottlebrush can survive winter and even some frost. The leaves may develop some browning during winter but they recover as soon as spring arrives.
To keep your plant warmer in winter, you can cover it with a burlap or a ventilated plastic wrap.
Get more flowers on your bottlebrush
Full sun is most important for good flowering. If you live in a colder region, plant the bottlebrush in a pot and keep it where it gets sun for long hours.
Add a slow-release low-phosphorus fertilizer as soon as the spring begins. Try using a fertilizer that has less nitrogen. This will reduce foliage growth and allow more flowers.
