About Zelkova serrata ‘Wireless’

Zelkova serrata 'Wireless' is a low, wide growing form of Japanese Zelkova, selected for a broad spreading vase habit that stays well under normal tree height. The foliage is fine and serrated, mid green through the warm months, turning orange, red and bronze in autumn across a densely held canopy.

It reaches about 5 to 6 metres tall and spreads to around 8 metres, adding 40 to 80 centimetres a year. Full sun and free draining soil suit it. It is frost tolerant, handling light to moderate frost once established, copes with wind, heat and pollution, and is drought tolerant after the first few summers.

The name points to its main use, planting beneath powerlines and in other places with a height limit, such as under building envelopes, near solar arrays or in low set streetscapes. It also works as a wide shade tree over seating and car parks. Councils specify it where clearance rules rule out taller elms.

Frequently Asked Questions

About Wireless Zelkova

What is Zelkova 'Wireless'?

'Wireless' is a cultivar of Zelkova serrata selected for a low, wide, vase shaped crown rather than the tall form of the species. It is deciduous, with fine serrated leaves that colour orange, red and bronze in autumn. The branching is dense and evenly spaced, giving a balanced canopy without much intervention.

How tall does 'Wireless' Zelkova grow?

About 5 to 6 metres tall with a spread of up to 8 metres, so it finishes wider than it is high. That proportion is the point of the selection. Allow the full 8 metres when siting it, particularly beside driveways, fences and boundaries, because the canopy reaches further than the trunk position suggests.

Can it be planted under powerlines?

That is the situation it was selected for. At 5 to 6 metres mature height it usually sits below low voltage clearance zones, which avoids the repeated topping that ruins the shape of larger street trees. Confirm the clearance requirement with the relevant network authority, since the rules differ between states.

How fast does it grow?

Moderate to fast, at 40 to 80 centimetres a year in good conditions. It reaches useful canopy width relatively quickly for a tree of this quality, which matters on projects that need shade within a few seasons. Growth slows as it approaches mature width and the canopy fills out and thickens.

Is 'Wireless' Zelkova drought tolerant?

Yes, once established. After two or three summers of regular watering it holds up well through dry spells, and it handles the heat, wind and reflected glare of urban sites. In the driest inland districts, supplementary water through summer keeps the canopy full and improves the autumn colour considerably.

Does it get Dutch elm disease?

Zelkova sits in the elm family but is highly resistant to Dutch elm disease, which is a large part of why it replaced elms in street planting overseas. Dutch elm disease is not present in Australia and strict quarantine keeps it out, so treat the resistance as insurance rather than a current need.

How do I prune and care for 'Wireless' Zelkova?

Water deeply through the first two or three summers and mulch the root zone, keeping mulch off the trunk. Prune in the first few years to clear crossing branches and set the framework, then leave it alone. It does not need reduction pruning to stay within height, which is the whole reason to plant it.

Plant Your Zelkova serrata ‘Wireless’ – Wireless Japanese Zelkova With:

Enriched Planting Mix (AO Certified)

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.
