Prunus Ukon Cherry Trees - Large Standards - Delivered by Mail Order from the Nursery with a 1 Year Guarantee
Prunus Ukon Cherry is one of the only yellow flowering cherry blossom trees. The flowers are creamy white with a faint yellow tint. This is a short but wide spreading tree, so allow about 11 metres for it to branch out.
Prunus Ukon trees can reach a height of about 6-8 metres.

How Standard Trees are Measured:
All the plants in the ornamental trees section are graded as standards, which means that they are measured by their girth in centimetres 1 metre above ground level (basically, their trunk's waist measurement). They aren't measured by their height, which will vary. So, a 6/8 standard has a trunk with a circumference of 6-8 centimetres and an 8/10 standard has a trunk 8-10 centimetres around.
This measurement makes no difference to the tree's final height.
Standard trees are 2 - 3.5 metres tall (on average) when they arrive; they are the most mature trees that you can buy from us. We cannot tell you precisely how tall your trees will be before we deliver them.
General description of Ukon Cherry trees:
Ukon is not a tall tree, but it will spread out to be wider than it is tall when it is mature, with a canopy about 10 metres across.Its buds are pink and the semi-double flowers are a pale, washed out yellow. The blossom appears at the same time as the young leaves, which are brownish bronze, turning a glorious dark red in autumn. These trees look best when they are planted in front of a green backdrop: a yew hedge is perfect.
History & uses of Prunus Ukon:
Ukon means "yellowish" in Japanese, which is an honest description of this tree's flower colour. A cherry tree with yellow flowers has long been sought after by gardeners and this variety is the best there is. It was introduced to Britain in 1905 and has won an RHS Award of Garden Merit.
Notes on planting Prunus Ukon Cherry trees:
Ukon Cherry trees prefer fertile, moist soil with good drainage. They like heavy clay, as long as the site doesn't become waterlogged in winter. They are good to grow on chalky soil.
Although they are tolerant of shade, we really recommend them for full sun. Cherry trees in the shade tend to become spindly and won't flower very well.
We don't recommend them for exposed, windy sites, where they will be blown out of shape by the wind.
Although your trees are hardy, late spring frosts can ruin their flower display. Avoid planting cherry blossom trees in frost pockets or North facing sites in colder areas.
Prepare your site before planting:
It is good to dig over the site where you plant a tree several months in advance. Kill the weeds first: for tough weeds like nettles, brambles and ground elder, you will usually need a glyphosate based weed-killer to get rid of them. When you dig the soil over, remove stones and other rubbish and mix in well rotted compost or manure down to the depth of about 2 spades.
Watch our video on how to plant a tree for full instructions.
Remember to water establishing trees during dry weather for at least a year after planting.
Tree Planting accessories:
Prepare your site for planting by killing the weeds and grass with Roundup weed killer.
You can buy a tree planting pack with a wooden stake & rubber tie to support the tree and a mulch mat with pegs to protect the soil around the base of your tree from weeds and drying out.
We suggest that you use mycorrhizal "friendly fungi" on the roots of all newly planted large trees: if your soil quality is poor, we strongly recommend it.
You can also improve your soil with bonemeal organic fertiliser and Growmore.
After you plant a tree, the most important thing to do is water it in dry weather. You will also need to weed around the plants. Watering should be thorough, so the ground is soaked. Let the soil almost dry out before watering again. Watering & weeding will be necessary for at least a year after planting.
Mature Ukon trees will benefit from a periodic tidying up. Remove straggly or poorly flowering side branches.
If your trees do need pruning, it is necessary to do this in summer to avoid the risk of silver leaf disease.
Special notes on caring for Ukon Cherry trees:
Prunus Ukon is an ornamental tree that will perform best when it receives a yearly mulch of well-rotted manure or compost to help keep the soil around it fertile.
Remember to check the stake and tie supporting your trees a few times a year. Tighten the tie if it becomes loose and loosen it as the tree grows. Make sure that the tree's trunk isn't rubbing against the stake.
Hygiene & Diseases:
Dead, damaged or diseased wood can be pruned off as soon as it appears.
Disinfect your pruning tools between every cut if there is any sign of disease.
Burn or dispose of any diseased material, do not compost it.

Delivery: Any order with a standard sized tree in it has a basic delivery charge of £12.55 + vat.
Because couriers sometimes experience delays, we schedule delivery by week, not by day. Therefore, please plan your planting day for the weekend at the end of the delivery week or for the week following delivery, at the earliest.
You can choose the delivery week that suits you during checkout and we will email you the day before your plants are due to arrive.
Payment: We do not charge your card until we begin to prepare your order for packing.
Guarantee: If any plants die within a year, we will replace them. We only ask that you follow our planting & growing instructions and sent us clear photographs of the dead plants in situ, so we can help to make sure that the replacement plants succeed. You only pay for the delivery of the replacements.
Please note that our guarantee is void if there is a hosepipe ban in your area: your newly planted trees must be watered in dry weather while they are establishing. The best way to water is very thoroughly every few days: at least once a week if there is no heavy rain.
Our nursery has been supplying large ornamental trees to gardeners since 1949. Our website started in 2003, so we do understand the concerns that you may have about buying specimen trees online.
