Medicinal Herbs for South East Queensland Gardens
Subtropical-friendly herbs with traditional medicinal uses. Grow them for tea, balms, poultices, or simply to have them on hand.
Best Medicinal Herbs for SEQ
SEQ's subtropical climate suits a wide range of medicinal herbs. Mediterranean herbs (rosemary, thyme, oregano, sage) grow well through the cooler months and struggle with summer humidity. Tropical herbs (ginger, turmeric, lemongrass) love SEQ's warm wet season. Native herbs (lemon myrtle, mountain pepper, pigface) are built for the local climate and deserve more love.

When to Plant Medicinal Herbs in SEQ
Mediterranean herbs (rosemary, thyme, oregano, sage, lavender) establish best when planted in autumn. Aim for March to May. This gives roots months to develop before summer humidity hits. Plant them in free-draining soil on mounds or in terracotta pots.
Tea herbs like chamomile, calendula, dill and yarrow prefer cool-season growing. Sow March to August. They bolt fast in Brisbane heat, so don't leave it too late.
Tropical herbs (ginger, turmeric) go in August to October. Plant rhizomes 5cm deep after frost risk passes. Harvest when leaves die back in winter, usually May to July the following year.
Mint, lemon balm, Vietnamese mint and lemongrass can be planted year-round from cuttings or divisions. They're forgiving as long as they get regular water in summer.
How to Use Medicinal Herbs Safely
Fresh herb tea is the simplest, safest way to use most medicinal herbs. A few sprigs in hot water for ten minutes. That's a culinary-strength brew. Good for daily wellbeing, digestion, winding down.
Infused oils and balms work well for calendula, chamomile, comfrey and lavender. Pack the jar with dried flowers, cover with olive oil, steep two to four weeks in a warm spot. Strain. Use directly or blend with beeswax for a balm.
Tinctures, concentrated extracts and therapeutic-strength internal use are a different matter. These preparations can interact with medication, affect liver function, or cause other issues at concentrated doses. Learn from a qualified herbalist or book before making them, and get professional advice before using them for specific health conditions.
Comfrey is a special case. It's excellent topically for bruises, sprains and bone injuries. Don't take it internally. The pyrrolizidine alkaloids can damage the liver.
Growing Medicinal Herbs in SEQ
Most medicinal herbs want full morning sun and some afternoon shade through summer. Raised beds or large pots suit Mediterranean herbs. Native herbs like lemon myrtle want the same conditions as any subtropical plant: compost-rich soil, mulch, steady water when young.
Harvest leaves in the morning after dew dries and before the heat builds. Essential oils are at their highest then. Cut sprigs above a leaf node and the plant will bush up.
Dry herbs by hanging bunches upside down in a warm, dark, airy spot. Avoid direct sun which destroys the active compounds. Once crisp (usually one to two weeks), strip the leaves into airtight jars and label. Stored in the dark, most dried herbs hold potency for twelve months.
