Best Fruit Trees To Grow In Idaho

Idaho’s high desert climate creates unique growing conditions where cold-hardy trees with low water needs perform best. If you are looking for the best fruit trees to grow in idaho, you need to focus on varieties that can handle freezing winters and dry summers. This guide will help you pick the right trees for your yard.

Many gardeners think fruit trees are too hard to grow here. That is not true. You just need to choose the right types. Apples, pears, and some stone fruits do very well. Let’s look at what works best.

The key to success is picking trees that match your local climate. Idaho has several growing zones. Most of the state is in zones 4 through 7. Some mountain areas are colder. The southern part is warmer but drier.

You also need to think about chill hours. This is the number of hours below 45°F that a tree needs to produce fruit. Idaho gets plenty of cold weather. So you need trees that require high chill hours. Low-chill varieties will bloom too early and get killed by frost.

Apple Trees For Idaho

Apples are the most reliable fruit tree for Idaho. They handle cold winters and hot summers well. There are many varieties that work great here.

Honeycrisp – Very cold hardy. Needs 800-1000 chill hours. Great flavor.
Liberty – Disease resistant. Good for organic growers. Needs 800 chill hours.
Pink Lady – Works in warmer parts of southern Idaho. Needs 700-800 chill hours.
Granny Smith – Late harvest. Needs 800 chill hours. Good for storage.
Fuji – Sweet and crisp. Needs 700-800 chill hours. Grows well in zone 5-7.

Apple trees need a pollinator. You need at least two different varieties that bloom at the same time. Crabapple trees can also pollinate your apple trees. Plant them within 50 feet of each other.

Pear Trees For Idaho

Pears are another great choice. They are almost as hardy as apples. They also need less pruning. That makes them easier for beginners.

Bartlett – Classic pear. Needs 600-800 chill hours. Good for eating fresh.
Bosc – Firm flesh. Needs 600-700 chill hours. Holds shape when cooked.
Anjou – Sweet and mild. Needs 600-700 chill hours. Stores well.
Kieffer – Very hardy. Needs 500-600 chill hours. Good for canning.

Pear trees also need cross-pollination. Plant two different varieties. Make sure they bloom at the same time. European pears are better than Asian pears for Idaho’s climate.

Plum Trees For Idaho

Plums can be tricky but some types work well. European plums are more reliable than Japanese plums. They handle cold better.

Stanley – Classic prune plum. Needs 800-1000 chill hours. Very hardy.
Mount Royal – Self-fertile. Needs 800 chill hours. Good for zone 4.
Green Gage – Sweet flavor. Needs 700-800 chill hours. Tender skin.
Italian Prune – Great for drying. Needs 800 chill hours. Heavy producer.

European plums are often self-fertile. That means you only need one tree. But planting two will give you more fruit. Japanese plums need a pollinator. They are also less cold hardy.

Cherry Trees For Idaho

Cherries are a treat but they need care. Sweet cherries are harder to grow than sour cherries. Sour cherries are more forgiving.

Montmorency – Sour cherry. Needs 700-800 chill hours. Very hardy. Great for pies.
North Star – Dwarf sour cherry. Needs 700 chill hours. Good for small spaces.
Bing – Sweet cherry. Needs 700-800 chill hours. Needs careful site selection.
Rainier – Sweet cherry. Needs 700 chill hours. Yellow fruit with red blush.
Lapins – Self-fertile sweet cherry. Needs 600-700 chill hours. Good for zone 5.

Sweet cherries need a pollinator. Sour cherries are usually self-fertile. Cherries bloom early. That makes them at risk for spring frost. Plant them on a north-facing slope to delay blooming. This helps avoid frost damage.

Peach And Nectarine Trees For Idaho

Peaches and nectarines are the hardest to grow in Idaho. They need warm summers and mild winters. Only try these if you live in the warmer parts of the state.

Reliance – Very cold hardy peach. Needs 600-700 chill hours. Good for zone 4-5.
Contender – Hardy peach. Needs 600-700 chill hours. Good flavor.
Redhaven – Classic peach. Needs 700-800 chill hours. Reliable in zone 5.
Mericrest – Cold hardy nectarine. Needs 600-700 chill hours. Good for zone 5.

Peaches and nectarines are self-fertile. You only need one tree. But they need protection from late frosts. Cover them with a blanket if frost is predicted. They also need well-drained soil. Wet roots will kill them fast.

Apricot Trees For Idaho

Apricots bloom very early. That makes them risky in Idaho. But some varieties can work if you choose carefully.

Moorpark – Classic apricot. Needs 600-700 chill hours. Good flavor.
Goldcot – Hardy apricot. Needs 600-700 chill hours. Good for zone 4.
Harcot – Cold hardy. Needs 600 chill hours. Disease resistant.
Westcot – Very hardy. Needs 600 chill hours. Good for zone 4.

Apricots are self-fertile. But they need a protected spot. Plant them near a south-facing wall. This helps them stay warmer in spring. Even then, you may lose crops some years to frost.

How To Plant Fruit Trees In Idaho

Planting correctly is just as important as choosing the right tree. Follow these steps for the best results.

Step 1: Choose The Right Site

Fruit trees need full sun. That means at least 6-8 hours of direct sunlight each day. More is better. Avoid low spots where cold air settles. Cold air sinks. That can cause frost damage.

Soil should drain well. Dig a hole and fill it with water. If the water is still there after 24 hours, the soil drains too slowly. You may need to build a raised bed or mound.

Step 2: Prepare The Soil

Idaho soil is often alkaline. Fruit trees prefer slightly acidic to neutral soil. Test your soil pH. If it is above 7.5, add sulfur to lower it. Mix in compost to improve drainage and nutrients.

Do not add fertilizer to the planting hole. That can burn the roots. Wait until the tree is established. Then fertilize in early spring.

Step 3: Plant The Tree

Dig a hole that is twice as wide as the root ball. The hole should be the same depth as the root ball. Do not plant too deep. The graft union should be 2-3 inches above the soil line.

Place the tree in the hole. Spread the roots out gently. Fill the hole with soil. Water deeply to settle the soil. Add a 2-3 inch layer of mulch around the tree. Keep mulch away from the trunk.

Step 4: Water And Care

New trees need regular water. Water deeply once a week during the first year. Established trees need less water. But they still need deep watering during dry spells.

Use drip irrigation or soaker hoses. This puts water at the roots. It also keeps the leaves dry. Wet leaves can lead to disease.

Pruning Fruit Trees In Idaho

Pruning is important for fruit production. It shapes the tree and lets light reach the fruit. It also removes dead or diseased wood.

When To Prune

Prune in late winter or early spring. This is before the tree breaks dormancy. Do not prune in fall. That can encourage new growth that will get killed by frost.

For young trees, focus on shaping. For mature trees, focus on removing crossing branches and opening the canopy.

How To Prune

Use clean, sharp tools. Make cuts at a 45-degree angle. Cut just above a bud or branch. Remove any branches that grow straight up or straight down. Keep the center of the tree open.

For apple and pear trees, use a central leader shape. For stone fruits like peaches and plums, use an open center shape. This lets more light in.

Pest And Disease Management

Fruit trees in Idaho face some common problems. Here is what to watch for.

Common Pests

Coddling Moth – Attacks apples and pears. Use pheromone traps and spray with spinosad.
Peach Tree Borer – Attacks stone fruits. Look for gum on the trunk. Use beneficial nematodes.
Aphids – Suck sap from leaves. Spray with water or insecticidal soap.
Scale Insects – Look like bumps on branches. Use horticultural oil in early spring.

Common Diseases

Fire Blight – Affects apples and pears. Prune out infected branches. Disinfect tools between cuts.
Brown Rot – Affects stone fruits. Remove mummified fruit. Spray with fungicide.
Powdery Mildew – White powder on leaves. Improve air circulation. Use sulfur spray.
Cedar-Apple Rust – Orange spots on leaves. Remove nearby junipers if possible.

Prevention is the best strategy. Keep your trees healthy. Water and fertilize properly. Prune to improve air flow. Clean up fallen fruit and leaves.

Harvesting And Storing Fruit

Knowing when to harvest is important. Fruit that is picked too early will not ripen well. Fruit that is picked too late will be soft and spoil fast.

When To Harvest

Apples are ready when they come off easily with a twist. Pears should be picked when they are still firm. Let them ripen indoors. Plums are ready when they are soft to the touch. Cherries should be fully colored and sweet.

Peaches and nectarines are ready when they have a sweet smell. They should give slightly to pressure. Apricots should be fully colored and soft.

How To Store

Store apples in a cool, dark place. They can last for months if kept near 32°F. Pears should be stored at 30-32°F. They will ripen at room temperature.

Plums and cherries can be refrigerated for a week or two. Peaches and nectarines do not store long. Eat them fresh or process them. Apricots also have a short shelf life.

You can freeze, can, or dry most fruits. This lets you enjoy them all year. Dried apples and prunes are easy to make at home.
