Kerr Applecrab
Kerr Applecrab
History: Kerr is an applecrab (cross between crabapple and apple) with Dolgo and Haralson parentage. It was developed at the Morden Research Station in Manitoba in the 1950s and named after plant breeder and ecologist William Les Kerr who was working at the station at the time.
Why We Grow It: The fruit is a pleasant dark red and unlike true crabapples, has a pleasantly sweet and tart flavour that makes it good for fresh eating. Although small, the fruit stores well and are quite juicy which makes them good for pressing. The juice does well when added to cider blends.

Growing Specs
Growing Specs
Canadian Hardiness Zone: 2
Soil Preference: Sandy loam, loam, clay loam. Prefers average to moist conditions, avoid planting anywhere that floods for more than two weeks in the spring. Generally quite adaptable to different soil conditions.
Flowering Time: Middle
Bloom Colour: White with pink streaks
Pollination Requirements: Partially self-pollinating, this variety will produce some fruit without an apple tree of a different variety but will produce more and better fruit if one is present. Like other crabapples and applecrabs, this variety is an excellent pollinator thanks to its large number of blossoms.
Sun/Shade Requirements:
Full sun (approx. 8-10 hours of sun daily)
General Growth Habits:
Moderately vigorous and precocious, very hardy, good crops, scab resistant and spur bearing.
General Disease Resistance Rating: High. This is a combined rating of how the cultivar produces and grows in our test orchard, along with the cultivar's known disease resistences/susceptibilities. Remember, just because a variety is susceptable to something does not mean it will get it. The microclimate, pests and disease present within your orchard/area will differ from ours too, creating a unique growing condition that may or may not induce certain pests or diseases.

CLICK HERE to see how shipping compares to pick up.
Shipping: Every year we ship thousands of trees across Canada (except BC due to CFIA regulations). We carefully bag roots in damp sawdust, then box them and send them out via courrier. CLICK HERE to see our shipping policy.
Pick-up: We also have thousands of trees picked up from our nursery each year. The pick-up options is free, though you must wait until you have been emailed a confirmation that your order is ready to pick up, which will have further information such as hours, locations, etc. We really appreciate if you can make an appointment to pick up, then we can be as organized as possible during our busy season.

Our grafted fruit trees are graded into three categories, and the size includes the rootstock:
- 50-80cm whip: may have some minor branching, this grade is like a "b-grade" size tree in industry standards; we include in this price category trees that are over 1m but have some scarring or mild crookedness.
- 1m+ whip: may have some minor branching, aka feathering. This is like a typical one-year whip in industry standards.
- 1m+ branched: these trees must be over a meter and have 3 or more branches 30cm or longer, as well as a central leader. They are essentially a two-year tree in industry standards.
- For stone fruits only - 1m+ whip/branched: We have combined these grades based on the way these trees grow and are grafted. Plums, apricots, cherries, and peaches naturally tend to grow more vigorously compared to apples and are more likely to form larger trees with more branches. However, we only chip bud them so they are a one-year old tree by industry standards. Apples and pears are partially bench grafted, and using the knip-boom method the grading becomes more complicated, hence the reason they are split into different grades.
Orders that are cancelled last minute due to size (being "to small"), will still incur the applicable cancellation fees if the trees are true to our grading standards as per the agreement of sale when the order was placed.
