What is Kiwi Orchid Bark No. 5 and what makes it different?
Kiwi Orchid Bark No. 5 is a premium, extra-large (25–50mm) raw Pinus radiata bark used as an airy orchid potting medium. It's un-aged, meaning it drains fast, stays chunky longer, and suits orchids that like to dry between waterings.
Which orchids is Kiwi Orchid Bark No. 5 best for?
It's ideal for large, thick-rooted orchids like Cattleyas, Cymbidiums, and some Dendrobiums or Vandas. Most Phalaenopsis and Paphs prefer finer mixes unless you're in high humidity or blending it down.
Should I soak Kiwi Orchid Bark No. 5 before using it?
Yes—pre-soaking helps hydrate the bark and stops it from repelling water. Soak for a few hours to overnight. You can also add diluted fertiliser to the soak water to give plants a gentler start.
How often should I water orchids in Kiwi Orchid Bark No. 5?
Water thoroughly when the bark is nearly dry. Soak or flush the pot, then let it drain fully. Check the inside of the pot (not just the top) using pot weight, a skewer, or touch to judge moisture.
How long does Kiwi Orchid Bark No. 5 last before repotting?
It typically lasts 3–5 years before breaking down, depending on watering habits and conditions. Replace when it gets mushy, stays too wet, or starts affecting root health and airflow.
Can I reuse Kiwi Orchid Bark No. 5 when repotting?
You can reuse firm pieces by rinsing them well and removing degraded bits. Most growers prefer refreshing with new bark to avoid salt buildup or compaction issues over time.
Should I mix Kiwi Orchid Bark No. 5 with other materials?
It works both solo or blended. Add sphagnum or coco chips for moisture, or pumice, perlite, or charcoal for extra drainage. Use it as a drainage layer too—better than rocks for airflow.
Does Kiwi Orchid Bark No. 5 hold water or dry too quickly?
It dries faster than fine bark or moss—great for orchids prone to rot. It holds some internal moisture but is designed for fast drainage. If drying too fast, tweak your mix or environment.
Can Kiwi Orchid Bark No. 5 be used for plants besides orchids?
Yes—it’s great for aroids, hoyas, bromeliads, and epiphytes when mixed properly. It can also be used as a natural top layer or in terrariums in small amounts for structure.
Will Kiwi Orchid Bark No. 5 cause fungus gnats or mould?
Not directly—bark is breathable, but constant wetness can invite gnats or surface mould. Let the mix dry properly between waterings and ensure good airflow to prevent issues.
Does Kiwi Orchid Bark No. 5 contain fertiliser or affect pH?
No—it’s free from additives and has stable pH. You’ll need to fertilise regularly with a gentle orchid feed. If needed, light buffering with lime can help, but it’s not essential for everyone.
What’s the best pot type for Kiwi Orchid Bark No. 5?
Use slotted orchid pots, baskets, or well-draining plastic or terracotta pots. Clear pots help you monitor roots and moisture. Adjust watering based on your pot and environment.
How should I store Kiwi Orchid Bark No. 5?
Store it dry and sealed in a clean, well-ventilated area. It should smell earthy and clean—if it ever smells sour or funky, it’s likely been stored wet and should be replaced.
Is Kiwi Orchid Bark No. 5 good for beginners?
Yes—if you're growing larger orchids that like to dry between waterings. It’s forgiving with airflow, but not suited to moisture-loving orchids unless mixed down or adjusted.
