Manchurian apricot is a species of edible apricot tree that is prized for its rapid growth and cold hardiness down to USDA Zone 3. Originally from Manchuria, or present day China and Korea, it develops white to pale pink flowers in spring, summer and fall fruits and bright orange fall foliage. Apricot trees are able to fruit when they reach maturity at between two and five years old. Beyond issues of maturity, apricot trees can fail to fruit if their basic requirements for soil nutrients, water and sunlight are not adhered to, if disease or insect infestations are present or if the tree is over fertilized.
Provide the preferred growing conditions for your manchurian apricot tree. Choose a full sun location that receives a bare minimum of six hours per day of direct sunshine. Maintain a nutrient-rich soil with a slightly acidic to neutral pH between 6.0 and 7.5 and water regularly to create even soil moisture that is consistently moist but not soaking wet. Remove any under plantings and competitive weeds regularly so as not to stress the roots.
Provide a pollinating partner or even a third apricot tree if your tree is not self-pollinating. Even self-pollinating trees will produce better fruit harvests when planted in the general proximity to another apricot tree and cross-pollinated.
Feed your manchurian apricot tree very lightly in the spring with a slow release granular fertilizer with a 10-10-10 guaranteed analysis. Feed according to the package label directions once per year. Do not over fertilize as excess nitrogen can impair flowering and fruiting.
Inspect your apricot tree carefully to look for signs of insect damage or disease which may impair bloom or fruit development. Sample any questionable looking insects, leaves or bark in a sealed plastic bag and take to your local nursery for diagnosis. Treatment with pesticides or fungicides can eradicate the problem, reduce the stress on the tree and restart the natural fruiting cycle.
