A hardy version of the classic evergreen magnolia

A favourite amongst estate landscapers for many years, this particular Magnolia has, in the past, been a bit harder to come by than its closest relatives such as Exmouth and Gallisoniensis. However, it is currently in high demand and rightly so as a hardier alternative to the above which flowers at an earlier age.

Like most Grandiflora, the huge glossy green leaves are contrasted with brown satin undersides ensuring an all year round treat.In late summer there is a beautiful show of truly giant white cup-shaped flowers, making Magnolia Grandiflora 'Goliath' an outstanding feature tree for any garden.

Keep well shaped by tidying up any damaged or unsightly growth in spring. If at all possible, plant this Magnolia in a fairly sheltered spot out of strong winds.

We have developed an eco friendly polypot that is currently in use across our 9 litre range. This polypot has less than 20% of the plastic used by a regular pot, and is importantly recyclable. Polypots also prevent root spiraling, 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.
How your order will arrive
Bare root and containerised trees have differing planting requirements, detailed below:

  • Watering: Bare root trees should have their roots soaked in water for up to 2 hours before planting, while with containerised trees, it is important to drench their root ball before planting.
  • Pruning: Another difference is that for bare root trees, it is useful to prune their woody roots back a few inches. However, for containerised trees, you should free any spiralized roots growing around their rootball's circumference.
  • Planting: With bare root trees, you should dig a hole to enable the graft point to be above the soil, while with containerised trees, the pot should sit no lower than an inch below the ground.
Bare root and containerised trees also share planting requirements, detailed below:

  • With both, 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.
Magnolia 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: While magnolia trees originate from North America and Asia, the varieties we stock have been specially bred to cope in colder weather. As such, they will be fully hardy in the UK climate.
  • Position: Magnolia trees benefit from being planted in full sun. Planting them in a sheltered spot will also help them put more resources into their flowering display.
  • 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 Magnolia’s growth. Waterlogged soils will starve them of oxygen, which plays a key role in photosynthesis; causing their roots to rot and creating an optimal environment for disease. Similarly, compressed soils can starve them of oxygen and water, so do not compress the soil when planting.
