Introduction

Underneath trees is often considered a challenging place to plant anything because of the shade, root competition, and dryness which are present due to the high consumption of moisture by tree roots. However, selecting the appropriate plants can make a big difference. In Australia, finding suitable plants that can grow in the shade, high competition areas, and nutrient-poor soils is quite challenging.

Factors to consider when selecting plants

Before selecting plants, several factors need to be considered, such as; tree species, soil, and sunlight levels. Tree species will have a significant influence on the plants that can be grown underneath. Soil type can also have a significant impact on the health of the plants as some trees prefer clay soil, while others prefer well-draining soils. The amount of sunlight available will determine if the plant will thrive or not.

Plants to grow under trees in Australia

The following plants are suitable for growing underneath trees in Australia:

1. Native violets (Viola hederacea)

Native violets are great groundcovers for shady and dry areas under trees. They have small green leaves with purple flowers, are hardy and need little care. They can grow in most soils but prefer well-draining soils. Native violets will not interfere with tree roots, making them an excellent choice for planting under trees.

2. Liriope 'Evergreen Giant' (Liriope muscari)

Liriope 'Evergreen Giant' is an elegant, hardy plant that can grow in the shade under trees. It has long, strap-like leaves with spikes of purple flowers in summer. Liriope is also low maintenance and will not compete with tree roots.

3. Hardy geraniums (Geranium species)

Hardy geraniums come in a wide range of colours and are an ideal plant for growing under trees. They thrive in a variety of soil conditions and are tolerant of shade. They bloom during spring and summer, adding colour underneath trees. Hardy geraniums do not have invasive roots, therefore making them a great choice for planting under trees.

4. Star jasmine (Trachelospermum jasminoides)

Star jasmine is a beautiful plant that is ideal for growing under trees. It has glossy green leaves with clusters of white flowers that produce a sweet fragrance during spring and summer. Star jasmine prefers well-draining soils and can grow in partial sun or shade. Its shallow roots do not compete with tree roots, making it suitable for planting under trees.

Care for plants under trees

Plants growing under trees will need special care to thrive. The following tips can help:

1. Water regularly

Plants growing under trees will often face dry conditions, so it is important to ensure they are watered regularly. However, ensure not to overwater as it can lead to root rot.

2. Fertilize regularly

Plants growing under trees will require extra nutrients as they will be competing with tree roots for nutrients. Fertilizing every few months can help the plants thrive.

3. Prune regularly

Avoid planting aggressive plants that will need regular pruning. This can lead to the death of the plants, as pruning can damage delicate root systems. Instead, choose low maintenance plants suitable for planting under trees.

Conclusion

Planting under trees in Australia can be challenging, but with the right plant selection and care, beautiful gardens can be created. Consider tree species, soil, and sunlight levels when selecting plants, and always remember to care for the plants regularly.
