Is it too late to join in?
I started with my first pings (and carnivorous plants) back in April, and I quickly got interested in setting up a rock garden.
I currently have three, and it's been an interesting trial and error experience.
I purchased 2 dragon stones and 1 red lava rock at a nearby exotic fish store, 1 large pumice stone from a seller on eBay, and 1 mystery rock (which I think may be black lava rock) as part of a rock kit from California Carnivores.
The exotic fish store had a good selection of dragon stones and red lava rock. The prices were definitely better than what was available online and I was able to pick the exact shape and size rock I wanted.
The large pumice stone was more expensive than all 3 rocks purchased from the exotic fish store but I was very excited to try it based on many reviews saying it was the best stone medium to use. After trying it out, I have to say it's not my favorite but more on this later.
And the mystery rock from California Carnivores is a very porous black rock that is as water wicking as pumice (but not as light as pumice when dry). It's okay so far but we'll see.
Out of the 4 types of stones I have, I'd have to rank them (from most liked to least liked):
- Dragon stone
- Mystery rock
- Pumice stone
- Red lava rock (because it's untested so I don't know how well it works)
To prep the rocks, I soaked them in distilled water for 24-48 hours as well as rinsed them off with distilled water. I also let the stones dry out before setting up my ping rock gardens.
I chose stones that were flatter so it wouldn't have too many issues wicking water as I read that compared to pumice or other more porous rocks, dragon stone and red lava rock was a lot less porous. Now, having tested it a bit, I can confirm it is true.
Maybe one day, I'll build a towering rock garden I see some people post about, but for now, a mini rock garden works well for me!
Part 1) The first dragon stone
This one had the following pings:
- Jaumavensis x Cyclosecta
- Colimensis
- Piggyback (cluster of 3, one is a tiny baby)
- Marilyn Monroe
- Ladyfingers (cluster of 2, although one is a tiny baby)
- El Mirador (one of the 2 I have in my collection)
- Ehlersiae x Mesophytica
I packed the many holes in the dragon stone with soil mix I purchased from California Carnivores and then I placed the pings on it. While packing, I would slightly water the soil mix so it would pack better and stay in place as I worked over the rock.
After the landscape/soil was ready, I used a clean metal chopstick to help dig a small hole for the ping roots and settle the soil around it after placing the pings down. So far, the metal chopstick or a small pair of tongs has been great for helping me place pings in soil.
After I placed all the pings, I also used a small makeup brush to brush away debris/soil from the leaves.
I didn't have any live moss on hand so I used a water wicking cord (the same ones you use for self-watering/bottom-watering indoor plant pots) and wrapped it around the rock to help it stay moist for longer. Overall, the cord works fairly well but eventually replacing it with live moss would be great. I love the look of the moss and the pings together but I can only handle one new thing at a time for now.
I added distilled water to the plate and tried to wait until the water was nearly gone before rewatering. Every few days, I might top water the rock with some droplets of water as the dragon stone really didn't stay "wet" for very long.
Here's the progress photo on this one:
Because some pings grew so much, I had decided to move the baby Piggyback a little away from the cluster and the "El Mirador" further away from the "Ladyfingers."
These grew really well in my opinion and I did (some time at the end of April/early May fed it fish flake paste as it wasn't catching any insects but haven't since then. There have been enough gnats overall but we shall see.
Part 2) The pumice stone debacle into the second dragon stone
When I finally purchased a large pumice stone, I was super excited. Everywhere I looked, people were recommending pumice stones as they were porous and great for water wicking.
I purchased from a seller on eBay and the stone already came with live moss so I thought I could do two things in one.
I placed my pings directly on the pumice stone, no soil mix added at all and it seemed like it was doing well for a while.
The pings on this rock was:
- Moranensis (Veracruz)
- Ehlersiae
- El Mirador
- Jaumavensis 'Cardonal'
I noticed that the pumice stone did in fact wick water a LOT better than the dragon stone. The water levels would disappear a LOT faster than the dragon stone.
Then one day, I noticed BLACK mold on the stone. I realized that the lack of air movement and sitting in a pool of distilled water all day was a great way to create a moldy environment.
The mold wasn't affecting the pings at all (for now) but I tried to clean up the mold with some alcohol swabs, drying out the stone, and letting it bathe in direct sunlight for a few days. I'm sure it had to do with bacteria from the live moss and location the pumice stone originally came from but I had no other ideas how to get rid of it without killing the pings as well.
It didn't work as fast or as well as I wanted and so I decided to use the second dragon stone I had.
The pings on the first dragon stone were doing well and I knew, based on experience, that mold wouldn't form in the same way.
So I switched over and the pings continued on without any issue.
Here is the progress photo on this one:
Part 3) The California Carnivores Rock Kit
I then ended up purchasing the rock kit from CaliforniaCarnivores.com, as I had purchased their beginner's pinguicula kit at first and I knew they had great pings and great soil and have overall been a really great vendor.
So I got the rock kit and the rock they provided (possibly black lava rock?) was very porous, exactly like the pumice stone.
I followed the rock garden video they had on Youtube and set up the environment mostly like theirs.
Since they gave two smaller rocks instead of one big one, I placed the two rocks against each other, stabilizing them with a handful of glass pebbles beneath them and placing the moss they provided in the crevice between them.
I added the provided soil mix all over various pockets in the rock and added the provided moss along the sides and in the crevices to help with water wicking.
The pings they provided to me this time were many clumps of tiny babies.
I tried my best to pry some of them apart and set them into the soil mix.
The list of pings on this rock garden:
- Lilac Lollipop => eventually replaced by "El Mirador" pups
- Esseriana
- Ladyfingers
- Agnata 'Red Leaf' x 'El Lobo'
- Neon Raspberry
- Piggyback
Unfortunately, the "Lilac Lollipop" pings I received didn't make it. I'm sad that I didn't pull any leaves before potting. I had honestly considered it (as it was one of the ones that looked a little rough after transport) but it just died a few days later. Instead, I replaced them with "El Mirador" leaf props I had that were ready for putting into soil.
All the other pings are doing fine overall.
Unfortunately, due to the porosity of the rock, it also has mold around it, but this time white mold. I'm managing it better with sunlight and dry out periods but I'll be keeping an eye out.
If the pings start to suffer for any reason, I have teacups ready for potting all these baby pings.
Here is the latest photo (no progress photo yet):
Final thoughts:
I do love rock gardens and I think I can definitely try different things moving forward.
I would love to eventually have a setup with rock and glass pebbles and sand in a type of zen garden style rock garden.
For now, it's enough to see the pings growing happily in their current home.
I'm still working on figuring out how to properly care/use the more porous rocks like pumice stone. Maybe when I have more duplicate pings LOL
I also feel like more delicate leaf pings (like the Moranensis Veracruz and the Lilac Lollipop) don't really like the rock garden as a medium. It just feels like they dont thrive as much as some of my other pings do. I may just move those back into pots if I still feel like they aren't progressing well.
Has anyone had that same experience? I would love to know!
