Huckleberry Care
If you want to grow blueberries, keep in mind the following essential care requirements:
- Plant in well-drained soil and mulch around the base of the shrub.
- Choose a location that gets at least five to six hours of direct sunlight.
- Water thoroughly when soil is dry.
- Supplement the soil with a balanced fertilizer in the spring.

Light
Huckleberry shrubs reach their maximum height (up to 10 feet for some species) when grown in partial shade conditions.
However, lower light exposure will reduce fruit production. If your primary goal in growing blueberries is to harvest fruit, you should plant your bushes in a location that gets at least five to six hours of sunlight each day.
Land
Plant huckleberries in well-drained soil with an acidic pH. Test your soil pH before planting and use a common soil amendment such as sphagnum peat moss or ferrous sulfate to make the soil more acidic if necessary.
Water
Huckleberry shrubs need regular watering, but the soil should not be soggy or wet. With regular rainfall, you may not need to water the shrub. But if rainfall is irregular, water deeply when the top layer of soil feels dry.
Temperature and humidity
Specific temperature and humidity requirements vary by blueberry species but these plants are winter hardy.
In fact, blueberry bushes need a period of cold to encourage fruit production during the growing season.
Fertilizer
Blueberries grow best in nutrient-rich soil. If the soil is naturally rich in organic matter, fertilizing may not be necessary. If the soil is lacking in available nutrients, use a balanced fertilizer such as a 10-10-10 in the spring.
Avoid fertilizing late in the growing season as this risks encouraging new growth to become vigorous and vulnerable during the winter months.
When, Where and How to Plant Blueberries
Plant blueberry bushes in spring, after the threat of frost has passed. Choose a planting site with well-drained soil and at least partial sun—or full sun if you want to maximize berry production.
If you plant multiple blueberry bushes, make sure there is at least 3 to 4 feet between bushes.
Dig a hole about twice the size of the shrub’s root ball. Place the plant in the hole and fill with soil. Gently press the soil around the base of the shrub and water thoroughly. Spread mulch around the base of the plant to improve moisture retention.
Huckleberry Varieties
There are several varieties of huckleberry shrubs native to North America. The huckleberry plant is Gaylussacia The genus is native to eastern North America while the shrub is Vaccine The genus is native to western North America. While the plants in Gaylussacia This genus is commonly known as the true huckleberry, the species in Vaccine This genus is also known as huckleberry shrub. Gaylussacia Huckleberry species are deciduous or semi-evergreen while some Vaccine evergreen blueberry
Genus Gaylussacia
- Gaylussacia baccata ‘Black Bilberry’: Native to eastern North America, this blueberry produces berries that mature to a deep blue-black color.
- Gaylussacia dumosa ‘Dwarf Blueberry’: Reaches a mature height of about two feet and has deciduous or semi-evergreen leaves. This shrub bears fruit in late summer to early fall.
Blueberry variety
- Vaccinium ovata ‘Evergreen huckleberry’: An evergreen huckleberry, this shrub is often grown for its ornamental foliage, which has ovate, blue leaves. Evergreen huckleberries are known for their abundant berry production, and the tart berries are often used for baking or making jams.
- Vaccinium parvifolium ‘Red Blueberry’: Instead of producing dark blue-black berries, this deciduous shrub produces small red berries that are tart and slightly sweet.
Huckleberry Plant Propagation
Huckleberries can be propagated by stem cuttings or grafting but be aware that successful grafting can be a challenge. If you decide to propagate by grafting, take hardwood cuttings in winter, when the mother plant is dormant and before the plant produces new growth.
Conversely, cuttings should be taken during the growing season, giving the mother plant a chance to provide nutrients for the new growth you desire.
Here’s how to propagate blueberries by cuttings or layering:
Cut
- Identify a healthy branch and cut a 5-inch section from the branch using pruning shears. Leave the top two or three leaves and remove all other leaves from the branch.
- Apply rooting hormone to the cutting.
- Fill a small container with soilless potting mix and plant the cutting. Moisten the soil and place the container in a warm, bright, indirect area of the house. Water regularly but avoid saturating the potting mix.
- Watch for signs of growth from the cutting; leaves and roots may develop within a few months. To check for root growth, gently tug on the cutting to see if you can feel resistance in the root system.
- Once roots have appeared and the threat of frost has passed in spring, transplant the cuttings outdoors.
Classification
- Select a branch from the lower region of the shrub that is long and flexible enough to reach the ground. Note that the branch will still be attached to the parent shrub but will be partially buried with the end of the branch sticking up into the air.
- Dig a 1- to 2-inch deep trench in the soil and bend the branch to fit into the trench. Remove some of the bark from the part of the branch that is above ground and apply rooting hormone, if desired.
- With part of the branch in the trench and the other end of the branch sticking up in the air, use a rock or stake to secure the branch. Fill the trench with soil.
- Occasionally turn over the buried cutting to check for roots; it can take several months for the cutting to develop a firm network of white roots. Once firmly rooted, you can cut the cutting away from the parent shrub and transplant the new shrub to the desired location.
Common pests
The most common pests of huckleberry shrubs include scale, spider mites, mealybugs, and aphids. In some cases, pest infestations can be resolved by physically removing the pests from the plant with a water hose or by plucking the insects out.
In other cases, you may need to treat the plant with neem oil or another insecticide product to control the infestation.
Common Problems with Huckleberry Plants
Since blueberries are often wild and have no closely monitored growing conditions, it can be said that they are relatively easy shrubs to care for.
However, here are the most common problems to be aware of when growing blueberries and common remedies to solve these problems.
Leaves turn yellow
If your huckleberry leaves start to turn yellow, there could be a few underlying causes. Overwatering can cause root rot, which will eventually cause the leaves to turn yellow. But another common reason for yellowing huckleberry leaves is an incorrect soil pH. Huckleberries thrive in acidic soil, so if the pH gets too high, yellowing—or yellowing—can occur. Use a soil amendment to increase the acidity of your soil.
Leaf spot
Brown, tan, or black spots appearing on huckleberry leaves may indicate a fungal infection. The most common fungi that affect huckleberries include Cercospora and Anthracnose. If you suspect a fungal infection, treat the leaves with neem oil.
Some of the most important steps to prevent the onset or spread of fungal infections include ensuring adequate air flow through and around shrub branches. Prune dead branches and trim as needed to allow good ventilation of the branches.
Replace the mulch every year. It is also important to note that adequate exposure to sunlight will reduce the risk of fungal infections.
Thick trunk with few leaves
Huckleberry shrubs with abnormal (or misshapen or discolored) stems are likely to be infected with a fungus that causes a condition known as witches’ broom. The invasive fungal disease can stunt the plant’s leaf and fruit production and disrupt the plant’s shape with swollen or twisted branches.
While you can prune away the unsightly branches of the shrub, there is no cure for this fungal infection so the only long-term solution is to remove and dispose of the shrub.
Frequently Asked Questions
-
Huckleberry bushes are slow to bear fruit, taking three to five years to produce fruit. Yields may be low initially as it can take up to 10 years for a huckleberry bush to produce a large amount of fruit.
-
You can sprinkle a thin layer of coffee grounds around the base of your blueberry plants to provide extra nutrients, but don’t expect used coffee grounds to significantly lower your soil’s pH. Instead, use an acidifier like sulfur.
-
You can grow huckleberry bushes in pots, but you will need to make sure the pot has adequate drainage holes and be prepared to replant the bush every one to two years until it reaches its mature size. Keep in mind that you will eventually need a large pot (as large as 10 or 20 gallons) to accommodate a mature huckleberry bush.
