Apples

GROWING APPLES is fun and rewarding, but failure to bear fruit is a common problem. Several factors may account for this including inappropriate site, improper cultural care, insufficient sunlight, stress from insects or disease, or poor pollination.

A plant only blooms when it reaches maturity. Most standard fruit trees require five to seven years after planting before they will bear fruit; dwarf trees usually bear within three years.

Fruit trees require at least eight hours of direct sun daily to grow, flower, and fruit well. Annual pruning and pest management is also required to maintain optimum health. But even with good cultural practices, a particularly harsh winter or a hard freeze in early spring can ruin that year's flower buds. Fruit trees that bloom very early, such as apricots, tart cherries and plums are especially vulnerable.

Even rainy weather during bloom can reduce or eliminate a crop by hindering the insects necessary to pollinate the flowers. Apples, apricots and hybrid plums require that two different varieties be located within 100 feet for pollination to occur.

Coninue on to 150 Years of Small Fruits

Zestar! apple.
'Zestar!'™ apple is the newest introduction from the U of M, selected for outstanding fresh eating quality and storage ability for an early apple. Marketable quantities of fresh fruit will be available by 2003.

Haralson apple.
'Haralson' resulted from the challenge to grow apples in Minnesota's harsh winters and was one of the first introductions by the U of M Agricultural Experiment Station. Almost 80 years old, yet still a favorite for fresh eating and baking, this tart fruit grows well in Minnesota conditions.

Regent apple.
'Regent' is named after the U of M Board of Regents. It is an attractive, red striped apple with well-balanced flavor that is excellent for fresh eating and baking.

Keepsake apple.

'Keepsake' is a small to medium apple, a 'lunchbox' variety, just the right size for kids' appetites. It is also popular because of its very sweet, almost sugarcane like flavor. Excellent for long storage.

Honeygold apple.

'Honeygold' has 'Golden Delicious' as one of its parents. It is very crisp with excellent, juicy sweet flavor.

Honeycrisp apples.

'Honeycrisp'™ apple is extremely crisp and juicy with a well balanced flavor, a true breakthrough in eating quality achieved by U of M apple breeders. The variety was 30 years in the making, from the original cross of two parents to the final introduction in 1991. The fruit stores for a remarkable six months — under normal refrigeration — and is exceptionally popular with consumers. To meet the demand, U.S. growers planted nearly 750,000 'Honeycrisp'™ apple trees in the 1990s. It is the most widely planted variety in Minnesota orchards and is being tested in other apple growing regions of the world including Europe, South Africa, New Zealand, and Australia.
