American Plum Tree

Watering

In the first year, deeply soak the soil around the tree once a week to encourage strong root growth. After that, water deeply every other week unless there’s significant rainfall. Aim for moist, not soggy soil. Reduce watering in winter when the tree goes dormant.

Sunlight

Your American Plum Tree thrives with at least 6 hours of direct sunlight daily. This ensures healthy growth and abundant fruit production.

Mulching

Apply a 2-3 inch layer of mulch around the base of the tree, keeping it away from the trunk. Replenish the mulch layer as needed to retain moisture, suppress weeds, and regulate soil temperature.

Pruning

Prune your tree in late winter before new growth appears. Remove dead, diseased, or damaged branches, and thin out crowded branches to allow for better air circulation and light penetration.

Fertilizing

Feed your tree a balanced fertilizer once a year in early spring to promote healthy growth and fruit production. Monitor your tree’s health and adjust fertilization as needed.

Pest and Disease Control

Keep an eye out for common pests and diseases. Use organic methods whenever possible, and only resort to chemical controls as a last resort. Early detection and intervention are key.

Protection

If you have deer or other wildlife in your area, consider fencing or using tree guards to protect your tree from browsing damage, especially during the winter months.

Upon Arrival

Give your newly arrived American Plum Tree a long, slow drink. Let the hose trickle at the base of the tree until the water soaks deeply into the surrounding soil.

In the First Year

Consistent moisture is crucial for establishing a strong root system. Water your young tree deeply once a week, soaking the soil thoroughly. Aim to keep the soil moist but not soggy.

After the First Year

Established American Plum Trees are fairly drought tolerant. Once a week to once every two weeks should suffice, depending on rainfall. Deep watering is still essential, so aim to soak the soil all around the root zone.

Seasonal Adjustments

Reduce watering in the fall and winter as the tree goes dormant. During hot, dry summers, you may need to water more frequently to prevent stress. Monitor your tree and adjust watering based on weather conditions.

Upon Arrival

Hold off on fertilizer for the first 4-6 weeks after planting your American Plum Tree. Let it settle in and establish its root system before giving it a boost.

During the First Year

Once spring arrives and the threat of frost has passed, feed your tree a balanced fertilizer like a 10-10-10 mix. Follow the application instructions based on the size of your tree. Spread the fertilizer evenly under the tree canopy, keeping it a few inches away from the trunk. Water the area well after fertilizing to help the nutrients reach the roots.

After the First Year

Continue with the annual spring fertilization routine. If your tree is thriving and producing good fruit, you can stick with the same amount of fertilizer. If the growth seems stunted or the leaves look pale, consider a soil test to identify any nutrient deficiencies and adjust the fertilizer accordingly. Keep an eye on your tree’s health throughout the season. Over fertilizing can lead to excessive foliage growth at the expense of fruit production.

Extra Tips

Supplement your annual fertilizing with organic matter like compost spread around the base of the tree in fall. This decomposes slowly, providing sustained nourishment and improving soil health over time. Remember, more isn’t always better – excessive fertilization can harm your tree and the surrounding environment.

When to Prune

Prune your American Plum Tree in late winter, ideally between February and March, before new growth begins. This allows the tree to heal properly before spring arrives.

Tools You’ll Need

Sharp pruning shears for smaller branches and a lopper for thicker branches. Make sure your tools are disinfected with rubbing alcohol to prevent the spread of disease.

Steps to Prune

Remove dead, diseased, or damaged branches. These detract from the tree’s health and appearance. Thin crowded branches. This allows for better air circulation and light penetration, encouraging healthy fruit production. Cut back any suckers (shoots growing from the rootstock). Shorten upright water shoots (fast-growing, vertical branches) to promote fruit production on lower branches. Make clean cuts at a 45-degree angle just above a healthy outward-facing bud.

After Pruning Care

Apply a light coat of pruning sealer to larger cuts to help prevent disease and promote healing.

Extra Tips

Avoid heavy pruning, especially in the first few years, as this can delay fruit production. Focus on removing problem branches and shaping the tree for optimal growth. If you’re new to pruning, consider consulting a certified arborist for guidance on proper techniques.

How long does it take for an American Plum Tree to produce fruit?

Most American Plum Trees will start producing fruit 3-4 years after planting, sometimes sooner with good care.

How much sun does an American Plum Tree need?

American Plum Trees thrive with at least 6 hours of direct sunlight daily. This ensures healthy growth and abundant fruit production.

What type of soil does an American Plum Tree prefer?

These adaptable trees can grow in a variety of well-drained soils. They perform best in slightly acidic to neutral soil with good drainage. If your soil is heavy clay, consider amending it with sand or planting your tree in a raised bed.

How big does an American Plum Tree get?

At maturity, American Plum Trees typically reach 15-25 feet tall and wide.

Are American Plum Trees self-pollinating?

No, American Plum Trees are not self-pollinating. You will need to plant at least two trees of compatible varieties within 50 feet of each other to ensure good fruit production.

How do I care for the fruit of an American Plum Tree?

Once your plums reach full color and begin to soften slightly, they’re ready to harvest. You can enjoy them fresh, use them in baking, or make jams and jellies.

How do I overwinter an American Plum Tree?

Young trees may benefit from a light layer of mulch around the base (a few inches away from the trunk) to protect the roots from harsh winter temperatures. Established trees are generally quite winter hardy.

What are some common pests and diseases that affect American Plum Trees?

Keep an eye out for common problems like aphids, tent caterpillars, and fungal diseases like black knot. Early detection and intervention are key! Use organic methods whenever possible and only resort to chemical controls as a last resort.

How long does an American Plum Tree live?

With proper care, American Plum Trees can live for 40-50 years, offering delicious fruit and beauty for generations to come.
