How to grow bay laurel in Australia
Also known as: Bay Leaf Tree, Sweet Bay, Bay Tree, Laurus nobilis
Bay laurel might be the most patient plant in this entire app. It takes a year or two to establish and doesn't rush, but once it's settled in, a bay tree is essentially indestructible. It handles drought, poor soil, coastal conditions, heat, and light frost — and in return it gives you fresh bay leaves indefinitely, for decades. There's a significant difference between a fresh bay leaf torn from a living branch and the dried leaves in supermarket jars: the fresh leaf has a much more complex, eucalyptus-like aromatics alongside the familiar resinous quality. Every serious home cook in Australia eventually wants one.
When to plant
Bay laurel is one of the most climate-tolerant culinary trees you can grow. Plant from spring through autumn in most zones. The tree establishes easily and doesn't need coddling.
Bay laurel doesn't perform at its best in truly tropical conditions — the combination of year-round heat and wet season humidity isn't ideal. It will grow and provide leaves, but the tree won't have the growth habit and leaf quality it develops in more temperate conditions. Subtropical and warm temperate zones are better suited.
Bay grows well in SE QLD — plant spring or autumn. It tolerates the subtropical climate better than many Mediterranean herbs, partly because it's not a sun-demanding plant. Good drainage is important.
Excellent conditions. Bay laurel is a Mediterranean native and does very well in Sydney's and Adelaide's climates, and is particularly happy in Perth's Mediterranean conditions. Plant spring or autumn. In Perth, bay is one of the easiest and most productive kitchen garden plants.
Thrives in Melbourne. Bay laurel handles Melbourne winters easily — established trees tolerate light frost without damage. One of the most reliable culinary trees for Melbourne gardens. Plant spring (September–November) or autumn (March–April).
Bay laurel is one of the few culinary trees that handles Hobart and Canberra winters. Established trees tolerate frosts to around -10°C. Young trees may need frost protection in their first winter. Long-lived and low-maintenance once established — a worthwhile investment for cool climate gardens.
Surprisingly well-suited to arid conditions once established. Bay laurel's Mediterranean origins mean it's accustomed to summer drought. Establish with regular water in the first year, then reduce to deep, infrequent irrigation. Handles dry heat well.

Buy a nursery specimen — bay laurel can be grown from cuttings but it's slow and easier to start with a plant. Cutting-grown plants are preferred over seed-grown as they're more reliable and faster. Most nursery plants are either cutting-grown or grafted.
Spacing: Bay laurel can be kept compact with regular pruning (it's one of the best topiary subjects) or allowed to grow into a tree 5–10m tall. In garden use, allow 3m from other trees and structures for a free-growing specimen. In pots, it can be kept much smaller indefinitely.
Depth: Plant rootball at soil level. Bay does not want a deep planting.
Soil: Adaptable to most soils — one of bay's great virtues. Prefers well-draining soil but tolerates clay better than most Mediterranean herbs. Avoid waterlogged positions. pH 6.0–7.5 is ideal but it tolerates slightly outside this range.
Pruning: Bay laurel can be clipped into any shape — it's one of the most popular topiary plants in Australia. Shaping also keeps the tree to a manageable size and stimulates fresh leaf growth (which is what you harvest).
Pots, raised beds, or in-ground?
Pots are an excellent option for bay laurel — the tree grows slowly enough to stay in a large pot for many years, and potting allows you to control the size and position easily. A 40–50cm pot produces a productive specimen. Standard bay topiary balls and standards seen at garden centres are pot-grown. Annual repotting into a slightly larger pot keeps the plant healthy long-term.
In-ground produces the largest, most long-lived specimens and requires the least maintenance once established. An in-ground bay tree in Sydney, Perth, Melbourne, or Adelaide can live for 50+ years and produce more leaves than any household needs. A genuine long-term garden investment.
Raised beds work well in areas with heavy clay soils — the improved drainage suits bay laurel.
Sunlight & water
Bay tolerates more shade than most culinary herbs — it will grow in 4–6 hours of direct sun and handles dappled light reasonably well. This makes it one of the few culinary trees suitable for partially shaded spots. Full sun produces denser, more vigorous growth, but the tree won't suffer in moderate shade.
Water young trees regularly in their first year. Established bay laurel is drought-tolerant — in-ground trees in cool-temperate and Mediterranean climates often need no supplemental irrigation once established. In pots, water more regularly (the pot dries out) but allow the soil to partially dry between waterings — bay does not want constantly wet roots.
When and how to harvest
Bay leaves can be harvested as soon as the tree has enough growth to sustain it — typically from the second year onwards for nursery plants.
Pick individual leaves or small sprigs as needed. Fresh bay leaves have a more complex, almost eucalyptus character than dried — use them fresh whenever possible. If you have more than you can use, dry sprigs by hanging them upside down in a cool, airy spot for 2 weeks. Store dried leaves in a sealed jar for up to 12 months.
Young leaves are milder; older, mature leaves are more strongly flavoured. Both are useful — young leaves for delicate applications, older leaves for long, slow braises and stocks.
Bay leaves are used whole in cooking and removed before eating — they remain tough even after cooking.
Common problems
Scale insects are the main pest — bay is susceptible to both soft and hard scale, particularly in warm, sheltered conditions. Treat with eco-oil or white oil. Regular inspection of the undersides of leaves catches infestations early.
Sooty mould follows scale — the black coating on leaves is a secondary fungal infection feeding on scale insects' honeydew. Treat the scale and the mould clears up.
Psyllids — tiny insects that cause the edges of leaves to roll inward (a protective gall-like response). Common in some parts of Australia. Treat with eco-oil; remove affected growth.
Root rot in waterlogged conditions is the primary cause of bay tree failure. Bay tolerates poor soil but not persistent wet feet. Ensure good drainage, especially in pots and in clay soils.
Yellowing leaves (chlorosis) in alkaline soils — apply chelated iron or a soil acidifier. More commonly seen in coastal calcareous soils.
Companion planting
Bay laurel shares its Mediterranean origins with rosemary, thyme, and sage — these plants have compatible growing requirements (drought tolerant, full to part sun, good drainage) and make natural companions. Planting them together creates a low-maintenance Mediterranean herb garden.
Marigolds as a companion deter soil pests. Beyond this, bay is a tree rather than a companion-planting subject in the traditional sense — it's more about what it doesn't compete with than what it actively benefits. Its slow growth and eventual size mean it can shade smaller herbs if not managed.
Australian varieties
Laurus nobilis (standard bay laurel) — the culinary species. All plants sold as "bay leaf tree" or "sweet bay" at Australian nurseries should be this species. This is what you want.
Aurea (golden bay) — a cultivar with golden-yellow new growth, fading to yellow-green. Slightly less vigorous. Primarily ornamental but fully edible — same flavour as the standard form.
An important caution: the plant commonly called "native bay" or "cherry laurel" (Prunus laurocerasus) is a completely different species that contains compounds toxic to pets and can cause toxicity in humans if ingested in quantity. It is also sometimes called "bay" in Australia. True culinary bay is Laurus nobilis — always check the Latin name. The leaves of Laurus nobilis have a distinctive aromatic smell when crushed; Prunus laurocerasus has little fragrance.
