Plum trees are a fantastic addition to gardens in Victoria, BC, offering fragrant blossoms in spring and delicious, juicy fruit in summer. However, if your plum tree isn’t producing as much fruit as you’d like, several factors might be at play, such as pollination issues, improper care, or environmental stress.

Here are 7 ways to get your plum tree to produce more fruit in Victoria, BC, and ensure your tree thrives in this region’s unique climate.

1. Choose the Right Plum Tree Variety for Victoria, BC

To maximize fruit production, it’s crucial to plant a variety of plum tree suited to Victoria’s mild coastal climate.

Tips:

• European plums like Italian Prune and Stanley are well-suited for Victoria and tend to be more disease-resistant.
• Japanese plums such as Shiro and Santa Rosa thrive in slightly warmer, sunnier spots.
• If planting more than one tree, ensure the varieties are compatible for pollination.

2. Ensure Proper Pollination

Plum trees often require cross-pollination to produce abundant fruit. Even self-pollinating varieties can benefit from having another tree nearby to boost fruit set.

Tips:

• Plant at least two compatible plum tree varieties that bloom at the same time.
• Attract pollinators like bees by planting pollinator-friendly flowers around your garden.
• Avoid using pesticides during bloom, as they can harm pollinators.
• If pollinators are scarce, try hand-pollinating by transferring pollen between flowers with a small brush.

3. Prune Your Plum Tree Regularly

Proper pruning is essential to maintaining the health of your plum tree and encouraging fruit production. Overgrown trees with dense canopies may struggle to produce fruit due to poor light penetration and airflow.

Tips:

• Prune your plum tree annually in late winter or early spring while it’s still dormant.
• Remove dead, diseased, or crossing branches to improve airflow and sunlight penetration.
• Shape the tree to maintain an open canopy, allowing light to reach fruit-bearing branches.

4. Fertilize Correctly

Plum trees need adequate nutrients to produce healthy fruit, but over-fertilization, particularly with nitrogen, can lead to excessive foliage growth at the expense of fruit.

Tips:

• Apply a balanced fertilizer in early spring and again in late summer.
• Avoid fertilizers high in nitrogen; instead, choose one with a balanced ratio of nitrogen, phosphorus, and potassium.
• Perform a soil test to determine nutrient deficiencies and amend accordingly.

5. Water Your Plum Tree Consistently

Victoria’s mild but often dry summers can stress plum trees, particularly during fruit development. Consistent watering is key to producing abundant, juicy plums.

Tips:

• Water deeply once a week during dry periods, ensuring the soil is moist but not waterlogged.
• Use mulch around the base of the tree to retain soil moisture and regulate temperature.
• Avoid overwatering, as waterlogged soil can cause root rot.

6. Thin the Fruit

Plum trees often set more fruit than they can support, leading to small, poor-quality plums. Thinning ensures the tree’s energy is focused on producing fewer but larger and healthier fruits.

Tips:

• Thin fruit when they are about the size of a marble, leaving 2–4 inches of space between plums.
• Remove damaged, misshapen, or overcrowded fruit first.
• Be careful not to over-thin, as plums rely on a good fruit load to balance their growth cycle.

7. Protect Against Pests and Diseases

Pests and diseases are common problems for plum trees in Victoria, BC, and can significantly impact fruit production. Common threats include aphids, plum curculio, and fungal infections like brown rot.

Tips:

• Inspect your tree regularly for signs of pests or diseases, such as holes in leaves, damaged fruit, or sticky residue.
• Use organic pest control methods, such as neem oil or insecticidal soap, to manage infestations.
• Prune infected branches and remove fallen leaves or fruit to reduce fungal disease risks.
• Apply dormant oil spray in late winter to kill overwintering pests and fungal spores.

Bonus Tips for Maximizing Fruit Production

• Plant in Full Sun: Plum trees need at least 6–8 hours of sunlight daily to thrive and produce fruit. Ensure your tree is planted in a sunny, well-drained location.
• Stake Young Trees: Protect young trees from strong winds common in coastal areas by staking them until their root system is well-established.
• Be Patient: Plum trees may take 3–6 years to start producing significant amounts of fruit, so consistent care and patience are key.
