Care Instructions for Australian Conditions
Light Requirements
Your Dieffenbachia Sublime will absolutely thrive in bright, indirect light where it receives plenty of filtered sunshine throughout the day! The gorgeous variegation will be most pronounced when given adequate light. That said, one of this plant's superpowers is its impressive tolerance for lower light conditions. It adapts beautifully to medium light situations and can even cope with low light areas, though growth will be slower. Just protect it from harsh direct sunlight, particularly during our intense Australian summer afternoons, as this can scorch those beautiful leaves. An east-facing window is ideal, or a few metres back from a bright west or north-facing window works wonderfully! The plant will naturally lean towards the light source, so give it a quarter turn every week or two to encourage even, balanced growth!
Watering
It's important to only water when it suits the environment your plant is living in - everyone's home is different! Your Dieffenbachia Sublime appreciates consistently lightly moist soil but absolutely doesn't want to sit in soggy conditions. A good general approach is to water when the top 2-3cm of soil feels dry to the touch, then water thoroughly until water drains from the bottom of the pot. The frequency will vary dramatically depending on your home's conditions, pot size, and the growing medium you're using. A chunky, well-draining mix will dry out faster than fine, peat-heavy potting mix, so adjust accordingly! During our warm Australian summers (December through February), you might find yourself watering twice weekly, whilst in our cooler winter months (June through August), once a week or even less frequently might be perfect. The leaves are wonderfully expressive and will give you clear signals - slightly drooping leaves indicate thirst, whilst yellowing leaves that feel soft might suggest overwatering. Let your plant guide you!
Temperature
Being a tropical beauty, your Dieffenbachia Sublime absolutely loves warmth and thrives in typical Australian indoor temperatures! It's happiest in temperatures between 18-26°C, which fortunately covers most Australian homes year-round! During our summer months, normal indoor temperatures are absolutely perfect. In winter, just keep your plant away from cold draughts from air conditioning units, open windows on chilly nights, or heating vents that create temperature fluctuations. These tropical treasures really don't appreciate temperatures dropping below 15°C, so if you're in a cooler climate region, keep your plant well away from cold windows during winter nights!
Humidity
Your Dieffenbachia Sublime naturally comes from humid tropical environments and appreciates a bit of extra moisture in the air to truly thrive! The good news is that grouping your plants together creates lovely natural humidity pockets that benefit all your green beauties simultaneously - it's like creating a mini jungle microclimate in your home! This is by far the easiest and most natural way to boost humidity levels. During our drier Australian winter months or if you're in an air-conditioned space, you might notice the leaf edges becoming slightly crispy, which indicates the air is too dry. A small humidifier nearby can work wonders if you notice this happening, though it's certainly not essential for this adaptable beauty. The occasional wipe-down of those large leaves with a damp cloth not only removes dust but provides a little humidity boost whilst keeping them looking absolutely spectacular!
Potting Medium
Your Dieffenbachia Sublime will reward you with vigorous growth when planted in a well-draining, aerated potting mix! A quality indoor plant mix works beautifully, but for even better results, try our signature Ultimate Aroid Mix - combine premium orchid bark, perlite, coco coir, coco chips, vermiculite, and a handful of horticultural charcoal. This chunky mixture provides excellent drainage whilst still retaining appropriate moisture, and those air pockets around the roots encourage healthy, robust root development! The plant really doesn't appreciate sitting in dense, compacted soil that stays soggy. When repotting (typically every 18-24 months), choose a pot just one size larger and ensure it has adequate drainage holes. This prevents the soil from staying too wet for too long, which is the main cause of root issues!
Fertilising
To keep your Dieffenbachia Sublime producing those stunning variegated leaves, we absolutely recommend feeding with Growth Technology Foliage Focus at every watering! Use 3-5ml per litre of water for optimal results. This complete, balanced fertiliser is specially formulated for foliage plants and contains all 12 essential minerals your plant needs to thrive. Additionally, incorporate Growth Technology Rootzone every 2-4 weeks (1ml per litre of water) alongside your regular fertiliser to encourage a robust, healthy root system that supports all that gorgeous top growth! This professional-grade combination ensures your plant has access to everything it needs to produce large, beautifully variegated leaves consistently. During our cooler winter months (June through August) when growth naturally slows, you can reduce feeding frequency slightly if you notice slower growth, though many plant parents continue their regular feeding schedule year-round with excellent results!
Seasonal Care Adjustments
Spring (September-November): This is prime growing season for your Dieffenbachia Sublime! You'll notice accelerated growth and frequent new leaf production. Maintain consistent watering as temperatures warm up, and ensure your fertilising routine is in place to support all that gorgeous new growth!
Summer (December-February): Your plant will be actively growing throughout our warm months! Watch soil moisture levels more closely as the warmer temperatures mean faster drying. This is often when you'll see the most impressive leaf production. Protect from harsh direct afternoon sun whilst maintaining bright, filtered light!
Autumn (March-May): Growth will gradually slow as temperatures cool and daylight hours decrease. Begin reducing watering frequency slightly as the soil takes longer to dry. Continue regular fertilising through early autumn, then reduce slightly as winter approaches!
Winter (June-August): Growth slows considerably during our cooler months, which is completely natural! Reduce watering frequency and allow the soil to dry out more between waterings. Maintain warmth and protect from cold draughts. This is a great time to give those leaves a gentle clean to maximise light absorption during shorter winter days!

Frequently Asked Questions
Why are the lower leaves on my Dieffenbachia Sublime turning yellow?
Some lower leaf yellowing is completely natural as your plant matures and redirects energy to new growth! However, if you're seeing multiple yellow leaves at once, it usually indicates overwatering. Check that your soil is drying out appropriately between waterings and that you have adequate drainage. Conversely, if leaves are yellowing and becoming crispy, your plant might be too dry or getting too much direct sunlight. Adjust your care accordingly, and your plant will bounce back beautifully!
Can I propagate my Dieffenbachia Sublime?
Absolutely! These beauties propagate wonderfully through stem cuttings, making them perfect for sharing with fellow plant lovers! Take a cutting with at least 2-3 nodes and a few leaves, dip the cut end in Clonex Purple Rooting Gel, and place in water or directly into moist potting mix. Use Growth Technology Clonex Clone Solution at 5ml per litre to encourage rapid root development. Spring and summer are the best times for propagation when the plant is actively growing. You can also propagate through cane cuttings or by air layering for larger specimens!
Is Dieffenbachia Sublime safe for pets and children?
No, this plant contains calcium oxalate crystals and is toxic if ingested by pets or children. It should be kept well out of reach of curious cats, dogs, and little ones. The sap can also cause skin irritation in sensitive individuals, so it's wise to wear gloves when pruning or handling the plant, and always wash your hands thoroughly afterwards. With sensible placement, this stunning plant can be enjoyed safely in your home!
How do I encourage bushier growth on my Dieffenbachia Sublime?
If your plant is becoming leggy or you'd prefer a fuller, bushier shape, you can prune it back! Simply cut the main stem to your desired height using clean, sterilised secateurs, and your plant will respond by producing new growth lower down the stem, creating a fuller appearance. The pruned top section makes an excellent propagation candidate! Regular feeding with Growth Technology Foliage Focus combined with Growth Technology Rootzone encourages vigorous, healthy growth. Adequate light also plays a crucial role - plants in brighter positions naturally grow fuller and more compact!
What's causing brown edges on my Dieffenbachia Sublime leaves?
Brown leaf edges are typically caused by low humidity, underwatering, or sometimes a reaction to fluoride or chlorine in tap water. Try grouping your plants together to create natural humidity, ensure you're watering consistently before the soil completely dries out, and consider using filtered or rainwater if your tap water is heavily treated. The plant can also develop brown edges if exposed to cold draughts or if the air is particularly dry from heating or air conditioning. Once you adjust these conditions, new growth will emerge beautifully!
Every plant we offer is carefully selected from our premium nursery stock and personally inspected for quality and health before dispatch, ensuring you receive a beautiful specimen ready to thrive in your Australian collection!

Shipping & Greenhouse Collection
Let's Talk About How Your Plants Get to You!
Alright, so here's the deal with shipping - we try our best to send all our plants potted and ready to go, but sometimes due to larger orders or when we're moving through some big changes, we'll send some plants semi-bare rooted. If you haven't come across this before, it basically means we carefully remove a bunch of the soil before packing them up. I know that might sound a bit scary if you've never ordered plants online before, but trust me, this is actually a really smart way to do it! The main reason we do this is because it creates so much more room in the box, which means we can fit way more plants in one shipment for you. More plants in one box = more green goodness arriving at your door at once! The plants honestly handle the journey better without all that heavy, wet soil sloshing around too. Just make sure you've got some fresh potting mix ready to go when your green babies arrive, because they'll want to get tucked into their new home pretty quickly!
Now, let's chat about what actually fits in our boxes. We can safely fit about 4-6 plants in one box, or if you're stocking up on supplies, one box can hold 3 bags of medium plus 1L of Growth Technology. We really don't recommend adding heavy items with your plants though - it just puts extra stress on your precious plants during transit and limits how many we can fit. If your order ends up being heavier than our standard box can handle, we'll reach out to you about additional postage fees. We're always transparent about costs, no sneaky surprises!
When Does Everything Ship Out?
Here's how our timeline works - we process and ship orders the week after you place them. So if you order on a Tuesday, your plants will get packed and sent out sometime the following week. We ship Monday through Friday (because let's be real, we all need weekends to recharge!), and we're aiming to get your order out within 4-6 business days of processing. Sometimes things take a tiny bit longer because we're a small but mighty team, and we take absolute care in making sure every single plant is packed perfectly. Like, we're talking individual attention for each plant here. We don't rush this stuff!
Once your order ships, you'll get an email with your tracking number. If you haven't received that tracking email, it just means we're still working on your order - it hasn't left us yet. Please be patient with us! We promise we're working as fast as we can while still making sure everything is done right. We pack orders in chronological order to keep things fair for everyone, so no one's getting special treatment or jumping the queue. First come, first served, that's how we roll!
The Journey to Your Doorstep
All our orders ship with Australia Post, and here's something cool - they operate 24/7! That means even if your order gets sent out on a Friday afternoon, it's still making its way to you over the weekend. The postal system doesn't sleep, and honestly, that's pretty amazing for getting plants to you quickly. You can generally expect your plants to arrive within 2-7 days after we ship them, depending on where you are in Australia. Metro areas tend to be quicker, regional spots might take the full week, but either way, your tracking number will keep you in the loop the whole time.
And here's the thing that always blows people's minds - our plants are absolute troopers. We've tested this extensively, and they can genuinely survive in their boxes for up to three weeks if needed. Obviously we don't want them sitting around that long, but life happens, mail gets delayed sometimes, and we want you to know that your plants are prepped and ready to handle whatever the postal system throws at them. While we do our best to avoid delays, occasional unforeseen circumstances may slightly impact delivery times, but rest assured, your plants are packed with extra care and are tougher than you think!
Quarantine States (WA, NT, TAS)
We currently only ship directly to non-quarantine states. Unfortunately, biosecurity restrictions make it pretty complicated to send plants to Western Australia, Northern Territory, and Tasmania. But don't worry, we've got a solution for you! If you're from a quarantine restricted state and would like to purchase plants from us, we recommend using Paradise Distributors' concierge service. They're absolute legends and can handle all the biosecurity paperwork and requirements for you. Make sure to contact them prior to purchasing so they can give you all the details and help you out: info@rareplants.net.au
Come Visit the Greenhouse! (Rockdale)
If you're local or just love the idea of picking up your order in person, we've got you covered! Greenhouse collection from our Rockdale location is available the same week you make your purchase. Our opening hours are always changing, so make sure to check booking availability on our 'Visit the Greenhouse' page before purchasing. After you've paid for your order, just head over and book a time slot that works for you. You'll get to pick up your plants AND have a wander through the greenhouse while you're here, which honestly is such a vibe. Just please wear a mask if you're feeling unwell - it's a small space and we want to keep everyone safe and healthy!
