*Heights are given as a very rough guideline and can have considerable variation based on species and supplier (each nursery experiences different growing conditions) It may even have been pruned before being sent out so we can only guarantee girth. Trees over 5.5m may include a delivery surcharge based on location and species.

Once a mature Prunus Ukon Flowering Japanese Cherry is over around 200cm/4 years old then girth is the best measure of value for money. For every girth measurement increment e.g. 6-8cm to 8-10cm (roughly 12-18months growth), the canopy will be wider, stronger, bushier and the root system larger as it has experienced 12-18 months growth. You can notice larger root systems with potted versions because the pot size increases with maturity. As a very general rule, each one cm girth measurement represents around 30cm growth but this doesn't apply to slow-growing trees.

Rootball means it will not come in a pot but will have the roots wrapped which you need to remove before planting and are available for delivery only between November and March.

Multistem means several stems starting very low to the ground. Comparing these with the same age Standard and Half Standard, these are typically shorter as growing several stems takes more effort than one stem.

Standard and Half Standard means lollipop shape. There is a more clear stem with a Standard.

A particularly good flowering cherry tree, Ukon has delightful hanging clusters of pale pink buds opening as semi-double pale greenish to creamy-white flowers from early Spring. A spreading tree - its large green leaves turn a rich rusty-red to coppery bronze colour before shedding each Autumn. Expect a height of around 6m at the 10-year point. It may go on to grow a few metres more but this is weather and soil condition related.

The Ukon is listed as 4 in the blossom scale, which means it is considered a later flowering variety compared to the other 4 groups (there are only 5 in total). The flowering period is April/May so late April or Early May should see the flowers breaking through. Weather and location can push this forward or backward.

The Ukon flowering Cherry tree has won the RHS Award Of Garden Merit, not for collecting enough tokens off that back of a cornflake packet but because it has outstanding characteristics when compared to other flowering Cherry trees.

It will tolerate chalk, sand, loam and clay soil as most other flowering cherry trees will, however, incorporating some well rotted organic matter in the hole when planting will speed things along. Acid, neutral or alkaline soils are also not a concern for the Ukon.

If possible plant in a full sun position that can be either sheltered or exposed.

As the Ukon is such a spectacular tree, it will be of no surprise to find it in parks, avenues and public gardens.

Prunus Serrulata Ukon as a rule requires little to no pruning other than to remove dead, diseased or crossing over branches. Should you be unhappy with the shape of the tree e.g. if the crown is too open (not very thick foliage) then consider pruning some of the larger branches back to encourage new growth. The concept is where you cut once 2 branches should grow to make the crown thicker and fuller.

Ornamental Tree Roots In The Shade e.g. Behind A Fence
It is more important that that foliage (posh term for leaves) receives the sunlight than the roots. So if the canopy of your ornamental tree can sunbathe but the bottom of your tree thinks there has been a nuclear winter then that is ok. You might want to ensure you have good drainage as water and no sun is the start of algae and other such issues.

Early Autumn Leaf Fall
Heat stress, being potted, lack of water, being boxed up for a few days etc can cause early Autumn leaf fall. Once planted, normal service will resume next season. 

Do I Need To Stake My Ornamental Tree?
9 out of 10 times the answer will be no, especially if under 200cm tall. However our article on Tree Staking should help guide you.

Climate Change
Warm and wet conditions from Climate Change have increased aesthetic foliage issues such as Powdery Mildew, Shothole, Rust etc These are not terminal issues and will usually last a season. All trees are inspected before being sent out to ensure they are fundamentally healthy. 

Planting In The Corner Of A Garden
Air and light is reduced in this location which could promote fungus and bacterial issues. If the corner is of the house and a fence then you also have leeching issues to contend with from cement and wood preservatives. Also when it rains, that area would experience higher water levels so we advise against it unless the plant is very hardy. 

Mature Tree Warranty
Once a tree is over 3 years old, the failure rate is considerably less and our Tree Warranty does not cover it at 100%. Please check details. 

Fruit On Ornamental Cherry Trees
If any fruits are formed, they will be small, inedible and barely noticeable.

Cheaper Ornamental Cherry Trees
There are cheaper cherry trees out there but you need to make sure that they are the same height and age, VAT and delivery is included in the display price, comes with a FREE TREE WARRANTY, certified virus free, UK grown and not cheaper EU imports used to better weather. A less expensive tree that dies is not cheaper.

If you get all that, let us know, we will try to price match.
