The Okame Cherry Tree: Does It Bear Fruit?
The Okame Cherry Tree is an ornamental flowering cherry tree hailing from Japan and the wider Asian region.
This tree, which boasts futuristic and intensely colourful blossoms, has become popular in the temperate regions of both hemispheres due to its unique ability to survive in certain cold climates; possessing a several-week flowering period and a strong tolerance of drought, this Japanese tree finds a home in a variety of places where other species might struggle.
But what about its crucial cultivation claim: does it actually produce fruit?
Most sources agree – the Okame Cherry Tree is not known for its fruit yield, where flowers are its main draw. Its Latin name, Prunus incisa, and its species name, Oumu, both indicate the non-fruiting status of this shrub.
At the same time, many orchard owners have presented some perplexing evidence by claiming to produce a small amount of fruit. In this regard, the answer largely depends on your location and the overall health of your particular tree.
For example, the climatic conditions of low humidity, a warm summer, and a long day length found in West Virginia are ideal for maximising Osame Cherry floral display, however – these same conditions can, in some cases, also promote fruit production.
According to a US study, the production of fruit depends on a combination of genetics, environment and soil. Dr. Rebecca Brown at West Virginia University said: ‘Most ornamental cherries produce very little fruit, if any. However, our data suggest that given the right environmental, soil and genetic conditions, flowering varieties can produce fruit. We believe that even the smaller yields can be beneficial to the public with fruit consumption, landscape beautification and wildlife attraction.’
While there is indeed evidence of fruit production, the Okame Cherry Tree is generally kept in urban and suburban gardens as an ornamental species, with its vitally-important flowering capabilities taking precedence.
Pruning and Plant Health
There are various ways to enhance the health of your Okame Cherry Tree, and to increase your chances of it producing a larger amount of fruit. Pruning is a major part of this, as this technique can be used for the purposes of stimulating regular flushes of flowers or to increase the amount of sunlight and air flow to the tree.
The practice of tree pruning is often seen as hazardous and requires the skills of an experienced arborist, as incorrect pruning can bring about fatal consequences to the plant. That being said, if you once again want to enhance the chances of your Okame Cherry Tree producing fruit, there are certain pruning techniques to be trialled. Pinching off new shoots by hand can increase the probability of blossom formation; however, the best advice is to contact a local plumber who can examine the plant and advise you further.
Signs of a healthy tree are general; if your Okame Cherry Tree is showing ongoing signs of health such as regular seasonal flowering, growth and renewed buds and branches, then the chances of it producing fruit are likely to be quite good. Conversely, if the tree is displaying signs of stress – leaves falling, discoloration or wilting – then the fruit production is likely to be minimal.
Fertilising and Plant Nutrition
The nutrition of the tree is a further element to consider when increasing the chances of fruit production. Fertilising is useful here, as the application of appropriate nutrients can be used to accelerate its growth.
Generally speaking, the Okame Cherry tree prefers a ‘well-drained’ location, and the soil should be kept moist for the best results. The tree has high nutrient needs and requires an annual application of manure, compost or a slow-release fertiliser to promote strong and regular flowering. A further annual application during the late winter – February or early March – can maximise the tree’s growth and promote floral production.
When fertilising your tree, it is important to follow the instructions on the label. The NPK ratio of the fertiliser – nitrogen, phosphorous, and potassium – will differ from one product to the next, so it is important to ascertain the correct ratio for your particular tree.
Pests and Disease
Finally, pests and diseases should also be kept in check before you can expect to achieve fruit production. The Okame cherry is especially susceptible to a variety of diseases, so regular maintenance should be a priority.
A good place to start is the leaves and branches; look out for brown spots, honeydew stains, wilting, scabs, leaf spots and premature colouring. Inspecting the tree’s trunk and root system can also be useful; look out for cankers, cavities and deadwood as these can all lead to infections.
As for pests, it is recommended that you use a pesticide to eradicate the critters, but be sure to read the instructions thoroughly before you apply the product. Taking the help of an arborist is also recommended if any disease is detected as they will be best placed to assess the situation and manage it accordingly.
Soil pH and Watering
Aside from pruning, fertilising and disease prevention, the Okame Cherry tree’s soil pH must be taken into consideration. A pH value of 5.5 and 6.5 is recommended; if your soil is too alkaline or acidic, then this can be corrected with the use of fertilisers and compost.
It is also important to carry out regular watering; the Okame Cherry tree prefers moist, but well-drained soil, so be sure to deep- water the area, as this will help in promoting strong growth. Too much water can, however, be damaging and cause root rot, so it is important to monitor the levels regularly.
Conclusion
So, in answer to the question, the Okame Cherry Tree does occasionally produce fruit. The extent of the production depends heavily on a variety of factors such as location and climate, as well as the general health of the tree. Pruning, fertilising, and keeping pests and diseases at bay are all necessary in increasing the chances of fruit production. Watering and maintaining the acidic levels of the soil can also prove to be beneficial.
