The Lilly Pilly hedge, also known as the Australian Cherry, is a fast-growing hedge frequently used for privacy screens and windbreaks. Covered in edible red and purple fruits, it can be used as a striking ornamental plant. These hardy hedge plants can grow into full-sized trees if given the right environment, but also take well to regular pruning. During summer they have bright white flowers, and later develop berries that can be eaten or used for canning. The Lilly Pilly is native to Australia and consequently does best in Australian environments.
Here is what you need to know about caring for your Lilly Pilly hedge.
Choosing Your Lilly Pilly Hedge
There are multiple varieties of the Lilly Pilly hedge, differing in size, flowers, and berries. Some can grow up to ten metres in height, while others stay much smaller. Some have larger or smaller leaves, and some will grow berries while some will not.
Here are some common Lilly Pilly varieties:
- Acmena smithii. This variety is resistant to psyllids, which makes it the ideal choice if you believe psyllids may be present in your garden or are already affecting existing plants. This is a larger Lilly Pilly that can grow up to five metres tall.
- Royal Flame. The Royal Flame Lilly Pilly stays under two metres, making it perfect for low hedges and small accents. Like Acmena smithii, it is resistant to psyllids.
- Tiny Trev. For a very small accent or a container plant, Tiny Trev is ideal. It grows under one metre, though it is not psyllid-resistant. For psyllid resistance in a compact format, look into the Hedgemaster, which also stays under one metre.
These are some of the best-known Lilly Pilly varieties available. Consider the conditions you will be planting into before you choose, as some are more resistant to drought while others are simply showier.
While many people plant Lilly Pillies specifically for decoration, the fruits are edible and can be used to make preserves and jams. They can also attract native birds. If you want a fruit-bearing hedge, make sure to choose a variety that will bear fruit; some hybrids will not.
How to Plant Your Lilly Pilly Hedge
Lilly Pillies will grow in most environments but prefer moist, warm soil. Soil that is too wet or that does not drain properly could inhibit growth or cause rot. Lilly Pillies can be planted directly into the ground or into a container, though container plants will need more frequent watering. Either way, they prefer a more fertile soil. If your soil is heavy clay or drains poorly, working in a quality soil amendment before planting helps open up the soil and give young roots a better start.
Because Lilly Pillies can be pruned and shaped, they are ideal for everything from windbreaks to topiary. They are also attractive to native birds, thanks to their fruits. As a hardy hedge, they can be planted and grown by virtually anyone.
Lilly Pillies can be acquired either bare root or potted. Either way, plant them in a hole that is twice the size of the root ball and backfill with moderately packed soil. Lilly Pillies prefer to be mulched so they can retain moisture, but excess moisture should be avoided.
The first year after planting will likely be the most vulnerable period. During this time, watch the plant to make sure it is growing and taking root properly, and water it regularly. Where young plants are exposed to browsing animals, a tree guard protects new growth while the hedge establishes.
How to Take Care of Your Lilly Pilly Hedge
Lilly Pillies can be regularly trimmed or even shaped into topiary during maintenance. While regular watering is advised (especially for container plants), most Lilly Pillies can otherwise be allowed to grow with minimal intervention.
On a semi-regular basis, inspect your Lilly Pilly hedges for any damage to leaves or stems. For container plants, check that the hedge has not become root-bound. If it has, transition it to a larger container.
If the weather becomes too cold, Lilly Pilly hedges may falter. Mulch in colder months and pay attention to any early leaf drop or frost damage on the leaves. Securing young stems with a soft plant or tree tie can also help stabilise plants during periods of strong wind or frost stress.
Common Problems with Lilly Pillies
Because Lilly Pilly hedges are extremely durable, there are few issues you are likely to encounter. Even so, some symptoms can indicate a larger problem. Here are the most common ones.
- Small bumps. If small bumps appear along the leaves, it is likely a pest known as the Lilly Pilly psyllid. This does not physically injure the plant but can be unsightly. Some Lilly Pilly varieties are naturally resistant, while others will need to be treated. This is one of the most common issues gardeners face with this hedge, and it should be addressed promptly before it spreads to other plants.
- Diseased foliage. If foliage begins to turn a burnt, orange colour, it may be Myrtle Rust. Myrtle Rust is a fungus common among myrtle family plants. Remove the diseased foliage and treat the rest of the plant with a fungicide. Diseased foliage can spread quickly and ultimately damage the plant.
- Stunted or unhealthy growth. Lilly Pilly hedges can be vulnerable to scale insects, which suck the sap from plants and leave them weak. Ladybirds and other predatory insects can help manage these pests safely and naturally. Stunted growth can also indicate root system problems or over-watering. Check that the soil around the plant is not too moist and causing rot. It may be that the plant simply needs more time between waterings.
Lilly Pillies are extremely low-maintenance, versatile hedges that suit a variety of situations. From decorative containers to full privacy screens, they are an excellent choice for any gardener. For the most part they are resistant to adverse conditions, and as long as they are in the right climate and placed correctly they should be a fast-growing addition to your garden.
