Grow Cherries In Western Australia: A Step-By-Step Guide

how to grow cherries in western australia

Cherries have been grown in Australia since the late 1800s, and Western Australia has seen significant new plantings in recent years. Growing cherry trees in Australia is notoriously difficult, but not impossible. The biggest challenge is getting them to produce fruit, as they require cold snaps to do so. They also need full sun to thrive and produce a good number of fruits. In this regard, it is important to grow a variety suited to your climate and space, as cherry trees can grow up to 15 metres tall, although dwarf varieties are available.

Cherry tree varieties: Choose a variety suited to your climate and location

Cherry trees can grow up to 15 metres tall, but dwarf varieties are also available, growing to a height of 1.5 to 2.5 metres. Dwarf cherry trees are perfect for small gardens and pots.

Different cherry varieties require different amounts of chilling hours (cold winter temperatures) to fruit successfully, so it's important to choose a variety suited to your climate. For example, Lapins, Stella, and Starkrimson varieties are self-fertile and need a cool climate. In contrast, Minnie Royal is a low-chill variety that requires a pollinator like Royal Lee. Trixzie White Cherree® is a miniature tree that needs a pollinator and thrives in cool climates.

Some cherry varieties require a compatible pollinating partner, while others are self-fertile and only need one tree to produce fruit. Self-fertile varieties include Lapin, Stella, Sir Don™, Morello, Starkrimson, and Bing.

When choosing a cherry tree variety, consider your location and climate. Cherries are typically native to the Northern Hemisphere and thrive in milder climates with regular rainfall. If you live in a cold climate zone or an area with a cool climate, such as mountain regions, cool inland tablelands, or parts of Tasmania or Victoria, you can try growing sweet cherries (Prunus avium) or sour cherries (Prunus cerasus). Sweet cherry trees can reach up to 10 metres tall, while sour cherry trees are smaller, about 4 metres tall.

In Western Australia, cherry production has been expanding in recent years, with significant new plantings in non-traditional areas. To improve fruit production, consider creating microclimates by planting against north-facing walls to create warmer areas or introducing ponds to generate more humid conditions.

Pollination: Some cherry trees need a pollinating partner, while others are self-fertile

When it comes to pollination, some cherry trees need a compatible pollinating partner to aid in pollination and fruit production, while others are self-fertile and only require one tree to produce fruit. The plant tag will indicate whether a pollinator is necessary. Self-fertile cherry tree varieties include 'Lapins', 'Stella', 'Sir Don', 'Morello', 'Starkrimson', and 'Sweetheart'. Dwarf cherry trees, such as PlantNet's Cherry Celebrations®, are also self-pollinating.

Cherry trees that require a pollinating partner include 'Minnie Royal', which needs a pollinator like 'Royal Lee', and 'Trixzie White Cherree', a miniature tree that does best in cool climates.

To successfully produce fruit, cherry trees need cold snaps or chilling hours. They are typically native to the Northern Hemisphere, where they thrive in milder climates and more regular rainfall. As a result, growing cherry trees in Australia can be challenging due to the varying climate conditions. However, with selective cultivation, some cherry tree varieties have been developed that are more reliable for growing in Australia.

To increase the chances of successful pollination and fruit production, it is important to choose a cherry tree variety suited to your specific location and climate. This includes considering the amount of chilling hours or cold winter temperatures required by different varieties. For example, 'Lapins' and 'Stella' are self-fertile varieties that prefer a cool climate and are available in dwarf forms, making them suitable for smaller spaces.

Additionally, proper pruning techniques can promote healthier growth and better fruiting. Pruning trees to encourage an open vase shape allows more sunshine to reach the centre of the tree, benefiting the fruit.

Sunlight: Plant in full sun, avoiding gullies and areas exposed to late spring frosts

When growing cherry trees in Western Australia, it is important to consider the amount of sunlight the trees will receive. Cherry trees require full sun to thrive and produce a good yield of fruit. While afternoon shade is acceptable, it is important to ensure that your cherry trees receive sunlight for most of the day.

When selecting a planting site, it is crucial to avoid gullies and areas that are prone to late spring frosts. Late spring frosts can damage the flowers of cherry trees, negatively impacting fruit production. Choose a location that receives ample sunlight and is protected from frost.

In addition to sunlight, cherry trees also require well-drained, moist soil to support their growth. It is recommended to prepare the soil before planting by mixing in compost and decomposed manure. This provides the trees with the necessary nutrients and promotes healthy root development.

The climate and variety of cherry tree are also important considerations. Cherry trees typically require a cool climate and can be sensitive to heat stress during establishment. Select a variety that is suited to your specific location and climate conditions. Some cherry trees require a cold winter to fruit well, while others can be grown in warmer temperate areas.

Pruning is another essential aspect of growing cherry trees. Pruning helps to promote healthier growth and better fruiting. It is recommended to prune the trees to encourage an open vase shape, which allows more sunlight to reach the center of the tree.

Soil: Prepare the soil with compost and decomposed manure, and keep it moist

Preparing the soil is a crucial step in growing healthy cherry trees. Before planting, it's important to ensure your soil is in the best condition. Start by digging a hole at least 40 cm wide and 30 cm deep. This depth is important for destroying perennial weeds and loosening the soil, allowing the roots of young cherry trees to establish and grow.

Enrich the soil with compost and decomposed manure. Compost helps to break down clay, increasing the fertility of the soil. It improves the structure of most soil types, binding sandy particles so they retain moisture and nutrients better. Clay soils can resist water infiltration, so compost helps improve drainage. If your soil is too acidic, avoid using peat moss as it will further reduce the pH level. Instead, opt for coir, which won't alter the pH.

Keep the soil moist, especially during the first few years. Regular watering is essential, and mulching can help maintain moisture levels. Watering needs vary depending on the season and weather conditions. In winter, once a week is usually sufficient, while in spring, rain typically provides enough moisture. During hot periods in summer, increase watering to 2-3 times per week to encourage new growth for the next season's fruit.

Pruning: Use the open vase pruning system to achieve ample airflow and sunlight

Pruning is essential for maintaining the health and productivity of fruit trees, and there are three main reasons to prune cherry trees: survival, stimulation, and shaping. The open vase pruning system, also known as the open-centre system, is one of the most popular shapes for pruning fruit trees and is well-suited to home gardeners. This method involves removing the leading branch and selecting four or five evenly distributed outward-facing branches to produce a shorter, wider tree.

The open vase system is intuitive for beginner gardeners and allows ample airflow and sunlight to reach the centre of the tree, which is important for reducing the development of brown rot on the fruit. It also keeps the fruit-bearing surface close to the ground, making harvesting easier.

To achieve the open vase shape, select three to five permanent scaffold limbs with wide angles (60 to 90 degrees from vertical) distributed evenly around the trunk, approximately 6 inches apart vertically. Small side branches along the scaffolds can be left for early fruiting. Avoid selecting primary scaffold limbs that are directly above one another.

After developing this framework, little pruning is needed beyond removing inward-growing or dead branches and annual pruning to keep the tree within its allotted space. Always use sharp pruning tools and make clean cuts close to outward-pointing buds to facilitate healing.
