What to grow under your fruit tree is a question frequently asked by home growers. Many gardeners want to get rid of the weeds under their trees, but aren’t sure what to replace them with.
We always try to answer it by referring to basic principles:
- Bare earth is the worst.
- Mulch is second-best (and some mulches are better than others).
- Best of all is a diverse mix of live plants.
As Dr Christine Jones explained in detail in this masterclass, growing live plants under your trees is healthier for the soil, the microbes, and your fruit trees. Ultimately, it’s also better for your health and the planet!
However, many people get stuck on which plants to grow under their fruit trees, which is why we created this guide to edible flowering plants. And we’re always on the lookout for examples of diverse understory plantings.
The amazing garden beds at Perth Cultural Centre
A visit to Perth led to us stumbling on these incredibly diverse garden beds. They make up the Urban Orchard, a delightful outdoor space that has been created on top of a carpark.
We talk about diverse understory plantings all the time. But this is the first time we’ve found a public garden dedicated to showing people what to grow under their fruit trees.
It’s not often that you get to see so many different combinations actually being tested.
So, with thanks to the Perth Cultural Centre, we’ll share some of the plant groupings here. Some of the trees weren’t looking super healthy, and not all of the understory plants that had been planted had survived.
But the amount of thought and planning that has gone into this garden makes our hearts sing. Most of the plants included in the groupings are edible. And most of the ones that aren’t edible have medicinal value.
In no particular order, here are a selection of the beds. We hope you find them as inspirational as we do.
Bed 10: Nectarine and white shatoot mulberry trees

Plants growing under the trees:
- Corn (Zea mays). Corn has high levels of antioxidant that increase when you cook it. It’s also high in niacin, potassium, magnesium, and essential fatty acids.
- Winter savoury (Satureja montana). This medicinal plant is a carminative (which means it helps to reduce farting!) and digestive aid. Also antiseptic and astringent. Can be used to relive insect bites.
- Purple basil (Ocimum basilicum). The purple variety of basil can be used in the same way as the more common green basil. Contains heaps of vitamins and minerals, and is packed with vitamin K.
- Tansy (Tanacetum vulgare). A medicinal plant, tansy has been used to treat painful joint conditions like arthritis and rheumatism. Can also be used to treat migraines, headaches, sciatica, nerve pain, ulcers, intestinal worms and parasites and to encourage regular menstruation.
- Snapdragons (Antirrhinum majus)
- Mallow (Malva). An anti-inflammatory herb, can be used to heal digestive and urinary tract infections. Also used for coughs and insect bites. High in calcium, magnesium, potassium, iron, selenium, and Vit A & C. Leaves can be eaten like spinach cooked or raw.
- Mint (Mentha). Fabulously useful culinary herb.
- Zucchini (Cucubita pepo)
- Finger lime (Citrus australasica). Rich in folate, potassium, and Vitamin E. Finger limes have more Vit C than other citrus.
- Ruby saltbush (Enchylaena tomentosa). The leaves and fruits of the Ruby Saltbush are both edible, however excessive quantities can make rheumatism, arthritis, gout, or kidney stones worse.

- Warrigal greens (Tetragonia tetragonioides). Native spinach with a similar flavour to spinach. Rich in Vit C and antioxidants, however contain high levels of oxalic acid so the leaves must be blanched before cooking.

Hopefully that is making your brain ping with new ideas about what to plant under your fruit trees.
The Urban Orchard was big, varied, and quite complex. Too much for one blog, so we’ll bring you the rest of the beds in another blog.

How does growing an edible understorey work with maintaining a coverspray on fruit trees? I used to grow herbs under my fruit trees, but I feel likecthey must be dripping with wettable sulphur and I don’t think this would be good to eat.
This is a great question Sarah and a good point. One way around it might be to grow things that you plan to harvest well after spraying? Or, grow beneficial ornamentals for colour & life in the garden! I understand that wettable sulfur is oftened used on vegetable crops as well so could be worth looking into how vegie growers might manage any risks from that. Meg – GGF team.
Hi Guys,
Thanks for the post on the Perth Cultural Centre and what to plant under fruit trees. Their solution for planting the olive tree is fantastic and is exactly what I need for our new turn around driveway – needed a rock breaker in certain areas to create. In response to you comment “But the amount of thought and planning that has gone into this garden makes our hearts sing. Most of the plants included in the groupings are edible. And most of the ones that aren’t edible have medicinal value.” It comes as no surprise to know that Josh Byrne Associates was involved in the Planning for this project instigated by The Metropolitan Redevelopment Authority. https://www.afr.com/companies/the-city-feeding-the-city-urban-orchard-bears-fruit-20150528-ghbnpd

Hi Veronica, thanks for this detail – it’s great to know (and unsurprising) that Josh was involved. Thanks for the links also, it’s good to learn more about this beautiful project.
Thanks for sharing Veronica! That makes a lot of sense! We’ll check out Perth City Farm, looks great. Meg – GGF team.
Can anyone tell me if it is possible to plant a peach tree in a flowerbed 6 feet away from edible Artemis herb plant
I read that citrus trees have shallow roots and so I’m wondering if I’m digging around my orange tree to plant the companion plants, will it adversely affect the tree?
