Enjoy an autumnal show of deeply-lobed, scarlet leaves...

Originally found in parts of Asia and Russia, this Japanese Maple is characterised by its burgundy, deeply lobed leaves which come autumn, mature to a scarlet shade that is impossible to miss! What makes this variety even more fascinating is that its foliage will change colour depending on the level of light it receives. In brighter locations, the foliage will become a richer shade of purple, while lower light areas result in greener-looking leaves. As such, you can appreciate colourful display from spring to winter that is unique to your garden's aspect. Acer palmatum is slower-growing than other popular trees, so importantly makes an ideal choice for those seeking a more manageable addition to their garden.

We have developed an eco friendly pot that is currently in use across our 9 litre range. This pot has less than 20% of the plastic used by a regular pot, and is importantly recyclable. These pots also prevent root spiralling, encouraging a healthier root system.

All trees arrive in an extra thick cardboard box with a clamp to hold their pot in place. This prevents them from moving around on their journey. 

Nursery staff will wrap the roots of our bare root trees and use compost to keep them moist during transportation. This extra protection prevents them from drying out, allowing for a flying start. We also use the same specialised box that our potted trees have to keep them nice and secure as they make their way to your home.

  • Watering: It is important to drench their root ball before planting.
  • Pruning: You should free any spiralised roots growing around their rootball's circumference.
  • Planting: With bare root trees, you should dig a hole to enable the pot to sit no lower than an inch below the ground. You should dig a hole that is twice the radius of their rootball. Stake your trees no more than 2 - 3 inches from the stem, and make sure that they are pointing away from the prevailing wind.
  • Fill the planting hole with a mix of compost and garden soil, finishing with fertiliser and mycorrhizal fungi. Take care to not compress the soil.
  • Once you are happy with your efforts, give your tree a generous watering.
  • Add mulch on top (this can be bark and wood chippings, compost, manure, leaf-mould, and stones), and ensure that these do not touch the stem of the tree.
  • Tie the stake to your tree (and leave space for growth), and place a rabbit guard around your tree to protect it from harmful pests.
  • Apply fertiliser and replace decomposed mulch come spring. In autumn, remove fallen leaves to prevent the risk of disease. You should also make sure that the ties are not rubbing your tree.

Maple trees are easy to grow. Their growth and output will likely be excellent providing you follow our planting and care instructions. Below we address some common query topics:

  • Hardiness: Maple trees can be found growing throughout temperate regions of the world, and are therefore well adapted to the UK climate.
  • Position: Japanese maples are suited to dappled shade, while red and Norwegian maples prefer full sun. Also planting your tree in a sheltered spot will help prevent uprooting in strong winds.
  • Soil: Soil types can be an unwelcome confusion as many plants will adapt to their conditions. Nonetheless, less than ideal conditions will certainly limit your Maple's growth. Waterlogged soils will starve your tree of oxygen, which plays a key role in photosynthesis; causing its roots to rot and creating an optimal environment for disease. Similarly, compressed soils can starve it of oxygen and water, so do not compress the soil when planting.
  • Pots: Japanese maples are perfect for pots and will benefit from mildly acidic soil. Potting with a mix of ericaceous compost and garden soil will produce a slightly acidic pH and a better soil structure overall. You may find that the pH rises over time, but you can maintain the acidity by watering with rainwater, and using pine needles and conifer bark as mulch. Larger species of Maple will still suffice in pots, but their growth will be restricted. However, this can be of benefit as they can grow to quite a large size.
