About Your New Acer rubrum 'Autumn Red' - Canadian Maple

Acer rubrum 'Autumn Red' turns a uniform brilliant scarlet in autumn, holding the colour longer and more consistently than seedling-grown red maples. Because it is a selected clone, an avenue of 'Autumn Red' colours at the same time and in the same tone rather than in a patchwork.

'Autumn Red' grows to 10 to 12 metres tall and 8 to 10 metres wide at 45 to 70 centimetres per year, holding a neat oval to rounded canopy on a straight central leader. That reliable structure is why it is specified so widely for streets, avenues and civic shade planting.

'Autumn Red' is frost hardy, surviving heavy and frequent frost without damage, and colours best in cool districts with cold autumn nights. It grows in full sun to part shade and prefers deep moist soil, tolerating wetter ground better than most maples.

Frequently Asked Questions

About Acer rubrum 'Autumn Red'

How big does Acer rubrum 'Autumn Red' grow?

'Autumn Red' reaches 10 to 12 metres tall and 8 to 10 metres wide, forming a neat oval to rounded canopy. It suits medium to large gardens, streets and avenues.

Why choose a named cultivar over a seedling red maple?

'Autumn Red' is a selected clone, so every tree colours at the same time and in the same tone. Seedling-grown Acer rubrum varies widely in both colour and timing.

When does 'Autumn Red' colour?

Foliage turns brilliant scarlet through autumn and holds well before dropping. Colour intensity depends on cold autumn nights, so it performs best in cool districts.

How fast does 'Autumn Red' grow?

It grows at 45 to 70 centimetres per year, which is moderate to fast for a maple and delivers useful canopy within five to seven years.

Is 'Autumn Red' frost hardy?

Yes. It survives heavy and frequent frost without damage and is well suited to cold tablelands and inland districts, where it also colours best.

Does Acer rubrum tolerate wet soil?

Yes. Red maples naturally occur on moist bottomland sites and handle heavier, wetter soils better than most other maples, though they still need reasonable drainage.

How far apart should I plant 'Autumn Red' for an avenue?

Plant 8 to 10 metres apart for an avenue where canopies will meet, or 10 metres apart where each tree should read separately.

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.
