About Your New Cornus x 'Eric Gennet' (Dogwood)

Cornus x 'Eric Gennet' covers itself in large creamy-white flower bracts through early summer, held horizontally along tiered branches so the display reads from above as well as from beneath. It is a hybrid dogwood bred for disease resistance and heavy reliable flowering.

'Eric Gennet' grows to 5 to 8 metres tall and around 5 metres wide at 30 to 60 centimetres per year, developing the layered horizontal branching that gives dogwoods their distinctive architecture. Autumn brings warm red and bronze foliage before the frame is revealed for winter.

'Eric Gennet' is frost hardy, surviving heavy and frequent frost without damage, and performs best in cool districts with reliable moisture. It grows in full sun with free-draining soil enriched with organic matter, and needs shelter from hot dry afternoon wind.

Frequently Asked Questions

About Cornus x 'Eric Gennet'

How big does Cornus 'Eric Gennet' grow?

'Eric Gennet' reaches 5 to 8 metres tall and around 5 metres wide, forming a layered horizontally branched canopy. It is a small to medium feature tree.

When does 'Eric Gennet' flower?

Large creamy-white bracts appear through early summer, later than the spring-flowering Cornus florida types, which extends the dogwood season in a garden.

Are the white parts actually flowers?

No. The showy white parts are modified leaves called bracts. The true flowers are the small cluster at the centre of each bract group, which is why the display lasts so long.

Does 'Eric Gennet' get autumn colour?

Yes. Foliage turns warm red through bronze in autumn before dropping, revealing the tiered branch structure for winter.

Is Cornus 'Eric Gennet' frost hardy?

Yes. It survives heavy and frequent frost without damage and performs best in cool districts, where both flowering and autumn colour are strongest.

What conditions does a dogwood need?

Free-draining soil enriched with organic matter, reliable moisture and shelter from hot dry afternoon wind. Dogwoods struggle in hot dry inland conditions.

How far apart should I plant it?

Plant 5 to 6 metres apart as individual feature trees so the layered horizontal branching can develop fully, which is a large part of the tree's appeal.

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.
