Reviewing The Growing And Care Of Bottlebrush Plant

Bottlebrush In The Garden By Raintree Annie

Four years ago we bought our first Bottlebrush. It is a plant I had wanted for years so was very happy to bring one home. The first picture shows it growing in a large pot in our garden.

However, when we first brought it home, at that time, I knew very little about how to care for it. 

Most of my plants were firmly outdoor garden plants but the bottle brush in our climate always seems to me to be halfway between a houseplant and a garden plant. 

Learning About Bottlebrush

So I knew I needed to learn about how to grow and care for it. Ours is the Callistemon citrinus or Crimson Bottlebrush. It is fairly common and easy to find. It is quite hardy, but I find requires winter shelter. It produces its stunning flowers mainly in high in summer with another smaller flush in Autumn and has been forgiving about my pruning to shape it.

There are several more cultivars including Alpine and Weeping varieties which are lovely. There are even Lemon Bottlebrush with lemon coloured flowers. So there are many to choose from for your needs.

The smaller dwarf varieties are especially useful for a small garden, patio or even a balcony. If you do not have a garden as such, a dwarf Bottlebrush would be lovely to bring some colour and style to a small outdoor space or indoor conservatory.

   

The name Bottlebrush comes from the beautiful red flower spikes that grow right at the end of the branches and simply look like a bottle brush! 

We knew it needed to grow in a very mid climate as the plant originates in Australia. We have a temperate climate sometimes it is very warm but most of the time it is mild or cool and in winter can be very cold indeed sometimes freezing conditions with frost and snow. So we decided it would be best to grow it in a large pot so that we could move it into a sheltered area easily.

Bottlebrush also requires free draining soil preferably on the acidic side and our soil is heavy clay. We did not think it would like the clay soil as it gets very cold and sodden in winter and sometimes becomes frozen and rock like. However, it is thriving in the free-draining ericaceous compost with grit and sand I added to the pot. 

I positioned it in full sun so it could take advantage of as much warmth and sunshine as possible. Ideally, it needs to be placed in a south-facing position or failing that a west facing position.

I have to admit for the first two years I was a little disappointed as there were no flowers. It was bought as a small plant though so I knew that as a gardener we do need a little patience. I also learned a lot the first year about how to care for it and it was very forgiving. With a little care and attention and doing the right things the plant was very happy and I reaped the rewards. 

The first year it flowered I was ecstatic!! The flowers were so beautiful and so prolific!!

Pruning And Care Of Bottlebrush

Especially in a pot it is necessary to water Bottlebrush regularly and to feed at least once a year in Spring and after flowering. I give an ericaceous feed and water when I feel the soil is dry.  In the ground you may only need to water if it is very dry for prolonged periods of time. 

I have rarely pruned our bottlebrush, only really to shape it. I prefer to just prune back lightly and cut just behind the faded flower spikes each year. Cutting back into the old wood is not advisable.

I have grown it like a shrub, but if you like you can prune it to make it look more tree-like with a single longer trunk. The variety I have can grow up to 15 feet tall so depending on where you are growing it, you may need to do light pruning to keep it in check annually or every other year. However, it can take 10 to 20 years to grow to its full height so it is not a plant that will get out of control very quickly.

 Of course with the dwarf varieties, the plant outgrowing its available space will not be an issue and pruning is simply to remove dead or damaged branches and clip to shape. If I got another one -which is very likely- I will buy a dwarf variety. 

 


I love the leaves, they are evergreen, aromatic, lance-shaped and the older ones are quite thick and dark green while the young ones are light green often just tinged with red and very soft and really lovely to touch.

The flowers here tend to bloom in high to late summer though this year ours still flowered in late November. In the winter I now keep it in our porch area which is very sheltered. In late autumn I cover it in several layers of thick garden fleece and so far it has been just fine throughout winter. If I had a conservatory or orangery I would certainly keep it in there all year round. 

I have never known ours suffer from any pests or diseases. However, it can be susceptible to red spider mite, scale insects and mealybugs though these tend to be more prevalent when grown in a greenhouse situation.

In terms of usefulness to wildlife, our bees love it in summer and can often be found happily feeding upon it! 

 


Bottlebrush is a beautiful evergreen plant requiring minimal care and attention once you understand its needs. It looks great all year round and especially gorgeous in summer and autumn with its vibrant flower spikes. It is a beautiful plant to grow and lovely to give as a gift for anyone who appreciates plants. 

As long as you have one of a garden, conservatory, greenhouse, orangery, a sheltered sunny spot, suitable soil conditions, or a large pot and a means of keeping it safe and sheltered in colder conditions I would recommend growing it.
