What Plants Will Grow Under a Large Blue Gum Tree

If you have a large blue gum tree on your property, you may be wondering what kind of plants can grow underneath it. This type of tree is known for its large canopy and potential to change the soil chemistry. However, with the right plant selection and care, there are a variety of beautiful, hardy plants that can thrive under this iconic Australian tree.

Understanding the Challenges of Growing Plants under a Blue Gum Tree

Before selecting plants to grow under your blue gum tree, it’s important to understand the challenges that come with planting in this environment. The canopy of the tree can create dappled or even full shade, depending on the time of day and season. The tree also drops large amounts of leaves, bark and gum nuts, which can make the soil acidic and nutrient-poor.

Plant Selection Tips

The following plants have been known to successfully grow under blue gum trees:

Ferns

Many ferns are adapted for growing in the shade and do well under blue gum trees. Some of the best ferns for this environment include bird’s nest ferns, maidenhair ferns, and mother ferns. These ferns can also help to create a lush, tropical feel to the area under the tree.

Groundcovers and Low Growing Plants

Groundcovers such as mondo grass, ajuga, and liriope are hardy plants that are well suited for growing under a blue gum tree. They are also low maintenance and will cover large areas with minimal effort. Other low growing plants that can thrive in this environment include violets, wintergreen, and sweet woodruff.

Herbs and Vegetables

If you’d like to grow herbs and vegetables under your blue gum tree, the best options are those that can handle shade. Cilantro, chives, basil, parsley, and lettuce are all good options to try. Be sure to enrich the soil with plenty of organic matter before planting, and make sure the tree is trimmed to allow more light to reach the area.

Tips for Growing Plants under a Blue Gum Tree

To ensure your plants thrive under your blue gum, try the following tips:

Remove Mulch

Remove a layer of mulch before planting, and then replace it with fresh mulch after you’ve added compost to the soil. This will help enrich the soil and provide nutrients for your plants.

Water Regularly

Water your plants deeply and regularly so that they do not dry out. Blue gum trees are also known to draw up a lot of water, so be sure to check the soil moisture regularly.

Prune Tree Branches

Trimming upper tree branches will help to encourage more sunlight to reach the plants below. It is best to trim branches in late winter or early spring before new growth begins.

Use Organic Fertilizers

Using organic fertilizers such as compost, manure, or blood and bone will help to replenish the soil’s nutrients over time.

Conclusion

Growing plants under a blue gum tree can be challenging, but it’s not impossible. By understanding the unique environment of a blue gum’s canopy, selecting the best plants for this location, and providing proper care, you can create a beautiful, thriving garden under your iconic Australian tree.
