A stunning Japanese Cherry admired for its unique yellow blossoms and colourful foliage

Admired by many for its spreading shape and creamy yellow blossoms, Prunus 'Ukon' will certainly become a treasured addition to your landscape. These semi-double flowers will be followed by abundant, ovate-shaped leaves which will initially be mid-green before maturing to red and eventually maroon in autumn. Because of these lovely characteristics, this ornamental cherry will keep your garden looking vibrant throughout the seasons! With an eventual height and spread of 5m x 4m, this tree is excellent for slightly smaller gardens, where it will make a stunning focal point as a single specimen.

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.

Easy to grow, a cherry blossom tree will make a perfect first tree. Your tree's growth and output will likely be excellent providing you follow our planting and care instructions. Below we address some common query topics:

  • Hardiness: Cherry blossom trees can be found growing in far colder regions than the UK and therefore these mild winters will not affect your tree.
  • Position: Cherry blossom trees are best planted in full sun, however they will also cope in more shaded locations.
  • 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 cherry blossom'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. Try to also avoid compressing the soil when planting.
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 spiralised 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.
