About Acer palmatum dissectum ‘Seiryu’

Acer palmatum dissectum 'Seiryu' is the only commonly grown upright laceleaf Japanese Maple. Where most dissectum cultivars cascade downward, Seiryu grows upward on a sculptural vase-shaped frame, carrying finely dissected green foliage that turns vivid orange, red and gold in autumn.

Seiryu grows slowly to 3-4 metres tall and 2-3 metres wide. The upright compact form makes it unusually versatile for a laceleaf maple, suiting courtyards, layered garden borders, Japanese-style designs, and large feature pots where height is wanted without sacrificing the delicacy of dissected foliage.

Seiryu performs best in cool to temperate regions including VIC, NSW Southern Highlands, ACT, Tasmania, and elevated parts of SA and WA. In warmer climates plant in part shade to protect the delicate dissected foliage from scorching, in well-drained soil with consistent moisture during dry spells.

Seiryu or Inaba Shidare? Both are dissectum (laceleaf) Japanese Maples with finely cut foliage. Seiryu is the only commonly grown upright laceleaf, with green spring foliage turning vivid red and gold in autumn. Inaba Shidare has a cascading weeping habit with burgundy-red foliage that intensifies in autumn. Choose Seiryu for upright height, or Inaba Shidare for cascading colour.

Plant Your Acer palmatum dissectum 'Seiryu' Upright Laceleaf Japanese Maple 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.
