About Your New Callistemon viminalis 'Dawson River Weeper'

Callistemon viminalis 'Dawson River Weeper' is a weeping form of the native Weeping Bottlebrush, with long pendulous branches that hang close to the ground and vivid red brushes through the warm months. The foliage is fine and soft green, and the whole plant moves in wind, which is a good part of its appeal.

It takes full sun to part shade and a wide range of soils, including heavy ground and sites that stay wet for periods near dams and creek lines. Growth is fast at 60 centimetres to a metre a year. It is frost hardy, surviving heavy and frequent frost, and moderately drought tolerant once rooted in.

Rural properties use it for shelter and creek line planting, councils for park and verge work, and home gardeners for a quick informal screen. Nectar brings honeyeaters and lorikeets in numbers. The weeping habit means it screens right down to ground level rather than lifting into a bare trunk over time.

Frequently Asked Questions

About Dawson River Weeper Bottlebrush

What is Dawson River Weeper?

It is a weeping selection of Callistemon viminalis, the native Weeping Bottlebrush. Long flexible branches hang from an arching framework, often reaching close to the ground, and vivid red brushes cover the plant through the warm months. The foliage is fine and soft green and it is held all year, so the plant never goes bare.

How big does Dawson River Weeper grow?

Around 4 to 6 metres tall and 3 to 4 metres wide when grown out as a small tree. It can be held at 2 to 3 metres as a screen with an annual prune after flowering. Because the branches sweep downward, it screens to ground level rather than lifting into a bare trunk.

How fast does it grow?

Fast, about 60 centimetres to a metre a year in good conditions, and quicker again in warm districts with summer rain. It is one of the better options when a screen is needed in a hurry. That pace holds for the first five or six years and then eases as the canopy fills out.

How far apart should I plant it for a screen?

For a dense informal screen plant 1 to 1.5 metres apart, or 80 centimetres apart if you want a tighter, more formal line. As a feature tree, allow 3 to 4 metres so the full weeping canopy can develop. For avenue planting, 3 metres apart gives a uniform, soft textured run.

Is it frost tolerant?

Yes, it is frost hardy and survives heavy and frequent frost without damage once established, which makes it usable well inland and on the tablelands. Young plants benefit from mulch over the root zone through their first winter. Cold weather does not affect the following season's flowering, and it is among the hardier bottlebrush selections.

Will it grow in wet or heavy soil?

Yes. Callistemon viminalis grows naturally along watercourses and copes with heavy clay and ground that stays wet for periods, which is why it is used in swales, dam surrounds and creek line revegetation. It also grows perfectly well in ordinary garden soil. The one thing it dislikes is permanently waterlogged, airless ground.

How do I prune and care for it?

Prune after the main flowering, cutting back into leafy growth to keep the plant dense and stop the canopy going bare inside. Feed with a low phosphorus native fertiliser in spring. Water through the first two summers to establish deep roots. Beyond that it asks for very little, other than removing any dead wood.

Enriched Planting Mix (AO Certified)

$21.95

Enriched Planting Mix is a certified organic blend of Pure Magic Compost, composted animal manure, gypsum, composted coarse bark and a wetting agent, bagged in 30L. It is built to be dug through existing garden soil at planting time rather than used on its own, and the gypsum is what sets it apart from a plain compost.

Gypsum helps break up heavy clay so water and roots can move through it, while the compost and manure return organic matter and nutrient to tired ground. The coarse bark holds structure and keeps air around the root zone, and the wetting agent keeps moisture in the soil longer after rain or watering.

Use it when planting trees, shrubs, roses, fruit trees and exotic garden plants, particularly into clay. Dig a hole twice the width of the pot and 7 centimetres deeper, then mix roughly one third planting mix through the excavated soil. Spread 7 centimetres of that improved soil in the base before setting the plant in.

Frequently Asked Questions

About Enriched Planting Mix

What is Enriched Planting Mix made from?

It is a blend of Pure Magic Compost, composted animal manure, gypsum, composted coarse bark and a wetting agent. Each part has a job. The compost and manure supply organic matter and nutrient, the gypsum works on clay structure, the bark keeps air around the roots and the wetting agent holds moisture in the soil.

What plants is it suitable for?

It suits exotic garden plants, including roses, ornamental and deciduous trees, fruit trees, shrubs and perennials, and it earns its keep most on heavy clay sites. It is a planting mix rather than a potting mix, so its job is improving soil at planting time. Phosphorus sensitive natives are the one clear exception.

Is it safe for natives?

No, not for the phosphorus sensitive ones. The composted animal manure in this blend lifts phosphorus well above what Proteaceae such as Banksia, Grevillea, Hakea and Protea will tolerate, and the result can be leaf burn, dieback and plant death. Use the Native Potting Mix for those species, or plant them into unimproved local soil.

Is it certified organic?

Yes. It is a certified organic product with no chemical additives, which is why the manure and compost in it are fully composted rather than raw. That makes it sound around fruit trees and vegetable beds, and it means you are adding genuine organic matter to your soil rather than a synthetic conditioner.

How much do I need?

Work on roughly one third planting mix to two thirds of the soil you dug out of the hole. For a shrub out of a 200 millimetre pot that is only a few litres. An advanced tree going into a large hole will take considerably more. Judge the quantity by the volume of the hole rather than the size of the plant.

Can I use it in pots?

It is not a potting mix and should not be used on its own in a container. The blend is designed to be diluted through garden soil, and used straight in a pot it holds too much water and settles badly. For containers, reach for a premium potting mix, or the native mix if you are potting natives.

Does it need to be watered in?

Yes. Water the plant well several hours before you plant it, then water thoroughly again once the hole is backfilled and the soil firmed down. That first deep watering settles the improved soil around the root ball and drives out air pockets. Keep the water up over the first few months while the roots establish.
