Orchard Establishment

Apricots, cherries, peaches and plums are called stone fruits because they have large pits or stones at their centers. Stone fruit trees are easy to grow, provided you accept a few limitations in northern climates. In Minnesota, it is important to select varieties that are hardy to zone 4 or zone 3. Most stone fruit varieties are very much at home in zone 5 and higher, but there are a growing number that are proving to be hardy in colder climates.

The trickiest part about growing stone fruits is the fact that they bloom early in the spring. Spring is notorious for temperature fluctuation. A few warm days might be followed by a cold night with frost, which is the biggest enemy of stone fruits. The delicate flowers are easily frozen, and a whole season's worth of fruit might be lost in a single cold night.As you can see, stone fruits pose a bit of a challenge in Minnesota, but don't let that worry you. The trees are relatively easy to grow and manage.

They may not produce fruit every year, and they may not live as long as a cold-hardy apple tree, but if you enjoy eating these fruits the weather gamble is worth it. In the years you do get fruit, you will get a lot of it. March— For existing trees, prune before growth begins, after coldest weather has passed. April, May— If last year's growth was less than 12 inches, apply compost around the base of tree. May through October— Water trees as you would any other tree in your yard, particularly during dry spells.

June, July— Cut to the ground any root suckers near the tree; they look like stout seedlings and have similar leaves to the tree. June through August— Place netting over trees as fruit ripens to prevent bird damage. November through March— Watch for deer and vole damage; put fencing around tree if needed. Variety tables provide hardiness, size and compatibility information for stone fruit varieties that have proven to do well in northern climates.

Remember, for most stone fruits, you will need to plant at least two trees that are compatible with each other to get fruit. Hybrid plums and apricots are self-incompatible, which means they require at least two different varieties located within about yards of one another for pollination to occur and fruit to be produced. Hybrid plums require a specific second variety for pollination see variety charts. For example, in order to get fruit from an Alderman plum, you would have to plant either a Toka or Superior plum as well or a native American or Canadian plum.

European plums and tart cherries are self-compatible. They do not require two varieties to produce fruit, however they will generally produce more fruit if a second variety is nearby.Select the right trees for your location and use these step-by-step instructions to plant and care for your young trees.

Many local nurseries are now carrying plum, cherry, apricot and even a few peach varieties suitable to this region. Mature height listed in this and other tables is an estimate.

Plant size at maturity will depend upon variety and growing conditions. Plums are very much at home in the Minnesota garden, provided you choose the right varieties. There are quite a few hybrid plum varieties, and a couple of European plum varieties that perform well in most areas of Minnesota. Local garden centers and online nurseries are carrying more and more hardy plums, making it easier for Minnesota gardeners to grow these delicious fruits. Plums, along with tart cherries, are the most reliable stone fruits for Minnesota gardens.

Fruit of various varieties ranges from deep purple to red to pale yellow, and the flavors are equally varied. Most require a second compatible variety to ensure maximum pollination and good fruit set. Toka is the most highly recommended variety for cross-pollination, as it is compatible with many other varieties. The fruit of Toka is delicious too! The following table includes suggestions for pollen-compatible varieties.

Wild American plums P. Truly wild plum trees are difficult to find at nurseries, but if you already have these trees in your yard they will provide pollen for your selected variety. Of all types of cherries, tart cherries also known as pie or sour cherries are best adapted to northern climates. Tart cherry trees are small compared to their sweet-fruited relatives, growing only to about 15 feet tall, and a few varieties only to about 8 feet—perfect for small spaces.

These attractive, vase-shaped to rounded trees have stunning copper bark and beautiful dark green, glossy foliage.

When in flower, the trees are covered with small, white, fragrant blossoms.Of all stone fruits, tart cherries are the most self-fruitful, but a second compatible variety will ensure even better pollination and fruit set. There are only a couple varieties that are hardy in Minnesota, and these are more delicate than plums or tart cherries. The fruit of hardy apricots isn't quite as juicy as those of warmer climates, but still has delicious flavor and is excellent for making preserves.

Peaches love warmth more than the other stone fruits, and so are the most limited in varieties that can be grown in Minnesota.

If you live in the southern part of the state or have a particularly mild micro-climate in your yard, you might have success with one of the few hardier peach varieties. These include Reliance, Contender, and Intrepid; befitting names for peaches growing in the North.

Gardeners in the Twin Cities growing these varieties report they get a moderate crop of peaches every year or so. If you're a peach lover, it's certainly worth a try. When planting multiple stone fruit trees, assume that the spread will be at least as great as the height.

In other words, two trees with a mature height of feet will need to be spaced at least 20 feet apart at planting. Choose the sunniest site available for planting, in a spot protected from harsh winds. Stone fruit trees require at least a half day of sun to produce fruit.

The more sun they get, the more fruit they can produce. Avoid planting stone fruit plants too close to the south side of buildings. Heat can get trapped there on sunny spring days and that will encourage trees to bloom too early.

At planting time, dig a hole large enough to fit the roots without bending them. Bent roots are less likely to spread normally as they grow, causing anchorage problems and susceptibility to drought.

If the plant is root-bound or if larger roots circle the inside of the pot, make several vertical cuts through the roots with a sharp knife and spread them out.This will not harm the plant, rather it will encourage the roots to extend and grow out into the soil. Do not add fertilizer nor heavily amend the soil from the hole at planting time as this can create a 'flower pot' effect, where the roots never leave the amended soil. When this happens, plants become root-bound with poor anchorage and low drought resistance.

You may mix in compost or dampened, shredded peat moss to the soil, but make sure at least half the resulting mixture is original soil. Spread about 4 inches of organic mulch, such as wood chips or well-rotted compost, around the base of the plant. Keep the mulch a few inches away from the trunk to prevent rotting and rodent damage.

Spread the mulch in a circle at least 4 feet in diameter. Grass and weeds should be kept at least 2 feet from the trunk throughout the life of the tree. For this reason, you should renew the mulch annually. Planting is also the perfect time to place a tree guard around the trunk.

These can be found at most nurseries and garden centers. The tree guard should cover most of the length of the trunk, which will protect it from rodent damage and winter injury. Occasional, slow, deep watering will encourage the roots to grow deeply into the soil. Avoid frequent, shallow watering because this will encourage roots to stay near the soil surface, leading to poor anchorage, susceptibility to drought, and other stresses. It is just as important not to overwater new trees.

Overwatering can lead to root rot and can kill the tree. Remember, if you are watering your lawn near the tree, take this into account when determining the tree's water needs. After the first year, regular rainfall should be sufficient for the tree. But watering will be required during hot, dry periods.

Young trees benefit from staking at planting time to help them grow straight and develop a strong root system.Once established, a stone fruit tree planted on a favorable site in properly prepared soil should thrive with minimal fertilization.

Nitrogen is normally the only mineral nutrient that needs to be added on an annual basis and can be added using compost. Never fertilize a tree exhibiting normal or vigorous growth. Too much fertilizer is more harmful than too little. If you fertilize the lawn surrounding a stone fruit tree, take this into account when calculating the amount to be applied to the tree. As stone fruits ripen, the flesh softens and the skin changes from green to purple, red, orange, or a combination of these colors.

You may test for ripeness by giving the fruit a light squeeze. The flesh should yield to gentle thumb pressure. To harvest without harming the fruit buds for next year's crop, twist the fruit slightly while pulling. Ripe fruit usually will detach from the stem with little effort.

Handle fruit gently and avoid piling fruit too deeply to prevent bruising. Refrigerate stone fruits right after harvesting in perforated plastic bags or loosely covered containers. Stone fruit trees are susceptible to trunk cracking in winter, especially when the trees are young. Often this is caused by fluctuating temperatures as the winter sun warms the bark on very cold days. You can find additional help identifying common pest problems by using the online diagnostic tools What insect is this?

You can use Ask a Master Gardener to share pictures and get advice. Significant insect pest damage is rare on stone fruits in home gardens, but these trees are occasionally subject to pests.

If you take time to look, you will find beauty in every season. Take a dormant apple spur for example. Oh, I know this short, wrinkled shoot is not much to look at, but with a little imagination you can picture the leaves and fruit it will soon bear. Spring will be here before we know it. Did you know that apple trees bear mixed buds meaning that they contain both flowers and leaves? Most mixed buds are found at the terminal end of spurs on two-year or older wood, so that is where the fruit will develop. These spurs may continue to bear fruit for ten years or more so we need to be careful not to damage them during annual pruning. Smaller buds elsewhere in the canopy are usually vegetative but still important as their photosynthesis sustains the tree and the developing fruit. Fire blight Erwinia amylovora is a bacterial disease affecting pome fruits like apple, crabapple, pear, and quince.

Types and Application of Grafting by Veronika Szabó PhD

Many home gardeners who grow fruit trees know that pruning is essential for best production. There are two basic systems with several variations on each used to train fruit trees. Central Leader System The first system is the central leader system, where a central or main trunk is developed with lateral branches coming off the trunk at regular intervals. Fruit trees typically pruned using the central leader system include apple, pear, pecan, cherry, and plum.

Hormones are produced naturally by plants, while plant growth regulators are applied to plants by humans. Plant hormones and growth regulators are chemicals that affect:.Plant growth regulators may be synthetic compounds, such as IBA and Cycocel, that mimic naturally occurring plant hormones, or they may be natural hormones that were extracted from plant tissue, such as IAA. These growth-regulating substances most often are applied as a spray to foliage or as a liquid drench to the soil around a plant's base. Applied concentrations of these substances usually are measured in parts per million ppm and in some cases parts per billion ppb. Generally, their effects are short-lived, and they may need to be reapplied in order to achieve the desired effect.

Growing apple trees as an espalier, or trained to a two-dimensional support, allows for a variety of fruit in limited space. Extra time and pruning skill.

The bud graft or chip budding

Many landscape plants should be pruned in February including fruit trees, grapevines, crape myrtle, ornamental grasses, boxwoods, hollies, camellia, evergreens and more. Pruning makes plants more eye appealing, corrects potential problems, keeps plants healthy and strong, and encourages more blooms and fruit.Tools used for pruning include bypass shears, loppers, and handsaws. Ensure tools are sharp and in proper operating condition before making your first pruning cut to avoid damaging the plant.

By Staff Report. Lots of fruit and nut trees can grow in Rowan County. Some of the most popular include apples, peaches, persimmons, pears and pecans. You can have an orchard even if you have the smallest of gardens, and be sure to try producing several different kinds. Variety selection is a critical step to consider before planting a fruit tree. Many people want to grow the same varieties that they buy in the grocery store, but some of these fruit varieties grow in climates very different from North Carolina.

Quite a lot, actually.
