More About Macodes petola

Macodes petola, to me, is the most coveted of all jewel orchids. Their leaves are crystalline and sparkle like gold flecks have been woven into the veins. It’s a stunning plant year-round and that’s why I had to have one. It took me over 5 years to find one available; so when I finally found a supplier (thanks J&L Orchids), I jumped at the opportunity and got two plants (just in case I killed one). The following care recommendations are according to my experience. If you know me, you know that I like bending the rules of orchid care – and my care for Macodes petola is no different.

So here’s the deal…EVERYTHING I read online harps incessantly on the need for Macodes petola and other jewel orchids (such as Ludisia discolor) to have HIGH HUMIDITY to do well. I have killed many orchid trying to stuff them into terrariums and that includes a few jewel orchids, so this time I tried something different. I started by watching the forums like a hawk and when I saw growers who had specimen-sized plants, I begged them for their secrets. Funnily enough, some of the best grown plants I found were grown by indoor growers…IN CANADA!

When it comes to growing these plants, THIS IS MY GOAL:

Macodes petola Care

These are my perspectives on care after growing them in my condo near an east-facing window. I find these orchids grow well as a houseplant provided they are given good light, but cool temps; their dark-green leaves may make them more susceptible to leaf burn, so use caution when trying to get them to bright enough conditions.

Jewel Orchid Care Tips

  1. Humidity isn’t a big deal – it’s not. If you disagree, I don’t care; show me your Macodes petola and then show me the study where you compared growth in high and low humidity. You will see, while humidity helps slow transpiration (the rate at which water is lost through the plant’s leaves), it doesn’t affect the plant’s ability to live (provided you keep it hydrated). Both of my plants grow in my dry climate with little issue. My humidity is often as low as 18% for many days, but as you can see they don’t appear to be suffering.
  2. Hydration IS a big deal – DO NOT LET THE ROOTS DRY OUT! I tested two types of media for my Macodes petola (based on recommendations from fellow Canadian growers) to help with this but the key takeaway is that dry roots or a dry plant, make it sulk and wilt. You want the roots moist, but in a potting mix that allows for good airflow.
  3. Macodes petola potting media – I tested both of these and found them to be equally valuable; I liked the first option more initially, because it took longer to dry out and bought me time if it was an exceptionally hot or dry week. However, after 6 months the second media had better performance (likely because of better airflow). Both media work well though, and I still have them potted in each:
    1. Orchid Mud Mix: Peatmoss (50%) + Perlite (50%) – It’s basically tropical plant potting soil…and it worked really well for my plant. During the winter it may have stayed too wet for how cool my temps were (16c); this didn’t kill any roots, but overall the growth seemed slower. That said, this plant also had a red mite infestation so the setback could be due to that.
    2. Classic Orchid Mix w/ more Sphag moss: Bark (20%) + Sphagnum Moss (50%) + Perlite (30%) – you want this to sit in a tray of water for at least the 3-4 months. After that period the bark tends to break down enough that it holds water longer. If you’re finding the media is drying too quickly (within days) then I’d recommend letting the tray sit in 1/4″ of water. Do your best to avoid letting the moss go bone dry. Like I mentioned above, if the roots get too dry, the plant sulks and you can set it back.
  4. Fertilize – weakly, weekly…and use a high-nitrogen organic fertilizer in the media (about 1/8th of a tsp); I like bloodmeal or a balanced organic fert called Gia Green – all-purpose fertilizer (4-4-4). When using fertilizers in your water, I spray the leaves as I’ve heard that jewels are heavy foliar feeders (take in nutrients through their leaves).
  5. Light – bright/in-direct but keep the leaves cool. If the plant isn’t getting enough light, they get tall and lanky. Light that works for “summer blooming phalaenopsis” is a good intensity for Macodes petola.
