Bottlebrush Care Guide

The Bottlebrush tree (Callistemon) has a fitting name – the spikes of flowers that bloom at the ends of the stem closely resemble a bottle brush. Nectar-feeding birds are attracted to the flowers. People are attracted to the Bottlebrush because of its dense and compact growth habit, which makes it ideal to use as a privacy screen. Native to Australia, this showy plant can grow as a tree or shrub. When properly cared for, Callistemon rewards its owners with bright, colorful blooms, as well as full and healthy dark green foliage. This resilient plant grows well in USDA hardiness zones 9 to 11.

Where to Plant Bottlebrush.

To get the most beautiful blooms, plant Bottlebrush in a location with full sun exposure. Full sun is at least six hours of direct sunlight each day. Once established, these plants can tolerate drought. They prefer soil that is moist but well-drained. These plants adapt to a wide range of soils. Constantly soggy or wet soil can be a problem. Plant them as an informal privacy hedge, accent to a desert yard, or mass planting over large areas. Landscape uses include border, coastal exposure, containers, cutting gardens, firescaping, hedge, mass planting, urban gardens, and specimen. The perfect size for smaller gardens.

How to Water Your Bottlebrush.

Once established, water Bottlebrush occasionally. To establish an extensive root system, water deeply and regularly during its first growing season. Once established, reduce the amount of watering. To water, deep soak around the root ball. Install emitters about one and a half feet from the trunk. If using a water hose, set the hose on a slow trickle so that it can thoroughly saturate the root ball. Be sure not to overwater and that there is no standing water.

How to Fertilize Your Bottlebrush.

Fertilization is beneficial for Bottlebrush. Fertilize in early spring, late spring, and early summer. Doing this maintains the look of deep green foliage and supports the growth and overall health of the plant. For best results, apply Moon Dust three times a year. So that you can remember easier, we recommend fertilizing with Moon Dust on Labor Day, Memorial Day, and Valentine’s Day. Apply Moon Juice every month. Those that live in Arizona and Nevada should supplement with our Soil and Water Conditioner because the water in these states is high in salt. You can purchase these beneficial fertilizers at any of our nursery locations in Arizona, California, Nevada, and Texas.

How to Trim Your Bottlebrush

Prune to shape, and do this after flowering. Do a heavy trim in early spring. Trim the suckers off the tree form – remove the suckers as soon as possible. When growing in a tree form, the drooping lower branches may need to be cut back.
