How to Grow Southernwood at Home Without Killing It

Save

Ever buy a plant thinking, “This’ll be easy,” only to watch it shrivel into crispy disappointment? Yeah, same. But Southernwood? Totally different story. It looks good, smells amazing, and doesn’t throw a fit every time the weather changes.

I’ve grown Southernwood (Artemisia abrotanum) in pots, beds, and just about anywhere it’ll fit. It’s an old-school herb with a clean, citrusy scent—and, bonus, it keeps moths away.

If you’re wondering how to grow Southernwood at home without killing it, you’re in the right place. Here’s everything you actually need to know—minus the fluff.

Pick the Right Spot (Because Southernwood is Kinda Picky)

Southernwood loves sun. I mean, it’s basically a sun-worshipping diva. Stick it somewhere shady and you’ll be rewarded with a sad, leggy mess that looks more like a mistake than a herb.

What it wants:

• Full sun: At least 6 hours a day. No, partial shade is not “good enough.”
• Well-drained soil: It hates wet feet. If your soil gets soggy, mix in some sand or compost.
• Low to medium fertility: Weirdly enough, too much love (aka rich soil) makes it floppy.

Pro tip: Southernwood is drought-tolerant once established. You won’t have to baby it with constant watering, just don’t ignore it during a heatwave or it might stage a protest.

Ever wonder why your plant turns yellow even when you water it? It’s probably drowning. Southernwood wants air in its roots, not a swamp.

Start from a Cutting (Unless You’re Weirdly Into Seeds)

Look, you can grow Southernwood from seed. Technically. But unless you enjoy frustration and failure, don’t. Most people start it from cuttings or divisions because seeds are slow and unreliable.

Here’s the easy way to start:

1. Snip a healthy stem about 4–6 inches long (non-flowering, please).
2. Strip the lower leaves and dip the cut end in rooting hormone (optional, but it helps).
3. Stick it in a pot with moist potting mix.
4. Cover it loosely with a plastic bag or dome to keep humidity in.
5. Wait 3–4 weeks, then check for roots.

IMO, propagation is the way to go. You get a clone of the parent plant, and it’s faster than waiting on seeds to wake up from their eternal nap.

Water Smarter, Not Harder

Southernwood isn’t one of those thirsty plants that cries every time you forget the watering can. In fact, overwatering is way more dangerous than underwatering.

The golden rule:

• Water deeply but infrequently. Let the soil dry out between waterings.
• In containers: Stick your finger in the soil. If it feels dry 1–2 inches down, water it.
• In the ground: Water once a week in dry weather. Skip it if it rained.

Got a plant that’s turning brown at the base? Might be root rot from too much water. Time to back off the hydration station. :/

FYI, if your Southernwood is wilting in the sun, check the roots before dumping more water on it. Sometimes it’s just transplant shock or hot weather, not thirst.

Prune Like You Mean It (But Not Too Much)

This plant grows fast and can get leggy if left to its own devices. You want it bushy, not floppy. So yes, you have to prune it. No, it’s not optional.

When and how to prune:

• Spring: Cut it back hard to encourage fresh growth. Like, really go for it.
• Summer: Light trims to keep it neat.
• Fall: Leave it mostly alone. Let it toughen up for winter.

Bold truth: Southernwood loves a good haircut. Pruning keeps it looking fresh and forces it to put energy into new stems and leaves.

Just don’t go Edward Scissorhands on it in fall or winter. That’s when it’s prepping for dormancy. Cut too much and it might not come back.

Keep It Contained (Unless You Want a Southernwood Forest)

Southernwood grows fast and wide. It can easily take over your garden bed if you let it. Invasiveness isn’t a huge issue, but it can crowd out your slower plants.

Best ways to control the sprawl:

• Use pots or containers: Great for patios and balconies too.
• Edge your garden beds: Southernwood spreads, but not aggressively.
• Divide every 2–3 years: Keeps the plant healthy and stops it from getting woody in the center.

IMO, containers are the MVP here. You get full control, and it looks great paired with other Mediterranean herbs like lavender and thyme.

Quick warning: Don’t plant it too close to tender flowers. Southernwood gives off compounds that can mess with nearby plants. It’s called allelopathy, fancy word for “I don’t play well with others.”

Use It Around the House (It’s Not Just for Looks)

Alright, let’s talk perks. Southernwood smells citrusy, camphor-ish, and just plain clean. Old-school gardeners swore by it for repelling moths and other insects. And yes, it actually works.

Here’s what you can do with it:

• Dry the leaves: Hang upside down for a few weeks.
• Tuck them in drawers: Bye-bye mothballs.
• Make sachets: Throw some dried leaves in a muslin bag.
• DIY air freshener: Crumble dried leaves into a jar or bowl.

You can also make a tea, but heads up, it’s bitter as hell. Some herbalists use it for digestion or as a dewormer (gross but true). I don’t drink it often, but I’ve tried it, and yeah… definitely an acquired taste.

And the bonus? Deer and rabbits tend to steer clear of Southernwood. It’s like they can smell that bitterness from a mile away.

Handle Pests and Problems Without Losing Your Mind

Southernwood is pretty chill when it comes to pests. Most bugs don’t like its scent, and it’s naturally resistant to disease. But hey, nothing’s perfect.

What to watch for:

• Aphids: They might show up if your plant’s stressed. Blast them off with water or neem oil.
• Powdery mildew: Happens in humid weather. Space your plants and avoid overhead watering.
• Root rot: Usually your fault (sorry). Let the soil dry out more between waterings.

Ever notice leaves going grey and dusty? That’s mildew. Cut off the affected parts, improve air circulation, and don’t crowd your plants.

Honestly, I’ve had fewer problems with Southernwood than with basil, tomatoes, or even mint. It’s like the introvert of the herb world, low-maintenance and doesn’t cause drama.

Wrapping It Up: Southernwood Is Kinda Underrated

So here’s the short version: Give it sun, keep the soil light, don’t drown it, and show it some pruning love. That’s it. You don’t need a degree in horticulture or a greenhouse full of gadgets.

Southernwood’s been hanging around gardens for centuries for a reason. It looks good, smells even better, and keeps the bugs (and possibly moths from 1983) away. Plus, once you know how to handle it, it’s practically foolproof.

Ever grown Southernwood before? Planning to now? Either way, don’t overthink it. Plant it, give it some sun, and let it do its thing.

Now if only keeping my houseplants alive were that easy… 🙂
