About Your New Acer truncatum x A. platanoides 'Warrenred' Pacific Sunset

Acer truncatum x Acer platanoides 'Warrenred', sold as Pacific Sunset maple, is a deciduous shade tree with a dense, broadly rounded crown. The lobed leaves are glossy dark green and unusually thick, holding condition through summer heat before turning orange to red in autumn. Yellow flowers open in spring before the leaves.

It handles full sun, heat, wind and reflected warmth off paving better than most maples, and takes a wide soil range provided drainage is reasonable. Growth is moderate at 40 to 60 centimetres a year. Frost hardy and drought tolerant once established, it suits temperate and cool temperate climates across southern Australia.

The compact crown makes it useful in streetscapes, car parks, driveway plantings and suburban gardens where a full sized shade tree would not fit. It also lines an avenue neatly at 3 metre spacing. For urban projects it gives canopy and autumn colour without outgrowing the space it was given.

Frequently Asked Questions

About Pacific Sunset Maple

What is Pacific Sunset maple?

Pacific Sunset is the trade name for Acer truncatum crossed with Acer platanoides, selected as the cultivar Warrenred. It is a deciduous shade tree with a dense rounded crown, thick glossy green leaves and orange to red autumn colour. It was bred for urban toughness and a compact crown, and carries small yellow flowers in spring.

How big does Pacific Sunset maple grow?

It reaches 8 to 9 metres in height and 7 to 8 metres across at maturity, forming a broad rounded crown on a single clear trunk. That is roughly half the spread of a full sized Norway maple, which is what makes it workable on suburban blocks and in constrained street plantings.

How fast does Pacific Sunset maple grow?

Moderate, about 40 to 60 centimetres a year once established. Advanced stock from 100 litre or 200 litre containers gives an immediate result and settles in quickly. Growth responds well to deep watering through the first two summers, after which the tree is largely self sufficient in most temperate soils.

Does it need sun or shade?

Full sun. The thick, glossy leaf surface was selected to handle heat and reflected light, and the tree holds condition through summer where thinner leaved maples scorch. It tolerates part shade, but the crown opens up and the autumn colour is weaker. Give it an open position with room for the canopy.

Is Pacific Sunset maple drought tolerant?

Once established it is noticeably more drought tolerant than most maples, which is the main reason it is specified for streets and car parks. It still performs best with occasional deep watering through extended dry spells. Through the first two summers after planting, treat it as a tree that needs regular water.

How far apart should I plant it for an avenue?

Plant 3 metres apart for a uniform avenue where the crowns knit together, or 3 to 4 metres apart if each tree is to develop its full rounded form. For single feature trees allow at least 4 metres of clearance from buildings, given the mature spread of 7 to 8 metres.

How do I care for Pacific Sunset maple?

Stake only if the site is windy, and remove the ties within two seasons. Mulch to 75 millimetres, kept off the trunk, and water deeply through the establishment period. Feed with a balanced slow release fertiliser in early spring. Prune in late winter to remove crossing wood and to lift the canopy over paths.

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.
