Ask the Experts: Growing cherry trees in Iowa

AMES — Cherry trees can be grown in Iowa, though some are not reliably hardy in all parts of the state. Iowa State University Extension and Outreach horticulturists tell how to select and plant cherry trees in Iowa.

Are sweet cherries hardy in Iowa?

‘Gold,’ BlackGold™ and WhiteGold™ are sweet cherry varieties (cultivars) that can be successfully grown in the southern half of Iowa. ‘Gold’ has golden yellow skin. It is self-unfruitful.

Another late blooming sweet cherry variety must be planted for pollination and fruit set. BlackGold and WhiteGold are self-fruitful, mid to late blooming cultivars. BlackGold has dark red skin, while WhiteGold is light yellow with a reddish blush.

Other possibilities for southeastern Iowa include “Hedelfingen” (self-unfruitful, red fruit), “Kristin” (self-unfruitful, purplish black fruit), “Sam” (self-unfruitful, dark red fruit) and “Van” (self-unfruitful, reddish black fruit).

Which sour (tart) cherry varieties perform well in Iowa?

“Northstar” and “Meteor” are two of the best performing sour cherry varieties in Iowa.

“Northstar” is a dwarf tree that commonly grows 8-10 feet. Its fruit has a mahogany red skin, red flesh and are 3/4 inch in diameter. “Meteor” is a semi-dwarf tree. Trees may eventually reach a height of 10-14 feet. The fruit is slightly larger than “Northstar” and has bright red skin and yellow flesh. Another possibility is “Mesabi.” It’s a cross between a sweet and tart cherry. Its red-fleshed fruit is sweeter than “Northstar” and “Meteor.”

What is a good planting site for cherry trees?

Cherries perform best in moist, well-drained, fertile soils. Avoid wet, poorly drained sites. Cherries are susceptible to root rots in wet, poorly drained soils. Trees also should receive full sun. Sites must receive at least six hours of direct sun each day. Sweet cherries bloom earlier than sour cherries. As a result, the flowers on sweet cherries are more susceptible to damage from late spring frosts. When selecting a planting site for sweet cherries, avoid planting in low spots where cold air settles on calm nights.

Also, avoid southern and western exposures that encourage early bloom.

Do I need to plant more than one cherry tree for pollination and fruit set?

Sour or tart cherries are self-fruitful. Self-pollination occurs when pollen is transferred from the anther to the stigma on the same flower, from another flower on the same plant or from a flower on another plant of the same variety. Only one sour cherry tree needs to be planted for pollination and fruit set. 

Many sweet cherry varieties cannot produce fruit from their own pollen and are considered self-unfruitful. These plants require cross-pollination for fruit set. Cross-pollination is the transfer of pollen from one plant to the flower of a different variety. When planting self-unfruitful cultivars, at least two different sweet cherry varieties must be planted for fruit production. While most sweet cherry varieties are self-unfruitful, BlackGold™ and WhiteGold™ are self-fruitful.

How long can I expect a cherry tree to survive?

Cherries are short-lived trees in Iowa, especially in poor sites. Sweet cherries seldom live beyond 10 to 15 years. Sour or tart cherries may survive for 20 to 25 years.

When selecting a planting site, be sure to choose a well-drained location.
