So your TCs showed up and you're itching to rip that flask open?! Hang tight friend — a little patience here is the difference between a jungle full of thriving plantlets and a sad pile of mush. Here's how we do it here in the Soil and Social Leaf Lounge.
Step 1: Let 'Em Chill First
Don't touch a thing for the first day or two. Take the bags out of whatever packaging they came in, but leave the plantlets sealed up inside the bag itself. Set them somewhere the temp stays steady — no AC vents blasting on them, no windowsill baking in the sun. A grow cabinet works great, or honestly your kitchen counter is fine too. They just came through a temperature swing getting shipped to you, so give them a minute to settle before you go messing with them.
Nerd Bite: There's actually no science behind this first step. I've deflasked immedately, I've waited. Neither mattered. So if you've got all your supplies and you're ready, go for it friend. Plants make us happy. Rules do not.
Step 2: Deflask and Trim the Junk
Once they've had their rest, cut the bag open and get your plantlets out. This is also when you trim off anything that's not doing the plant any favors — dead or yellowing leaves, roots that are clearly toast. Don't panic if a few leaves look rough coming out of the flask. That's normal. Cultures almost always need a haircut on the way out.
Pro Tip: If you struggle with root rot/stem rot on your monstera tc's, try cutting the roots. I know it sounds crazy ... but when we moved to humid Oklahoma in 2013 I had NO idea how humid it was here! I had a lot of rot issues, only monstera so I know it wasn't a lab issue or a cleansing issue. I switched to cutting the roots back thinking that would give less excess material the chance to rot ... and I must say it's worked very well every since. I also personally put my monstera in sphagnum moss, everthing else goes in a peat moss plug.
Step 3: Rinse That Gel Off — All the Way
This is the step people rush and shouldn't. Get every last bit of that agar gel off the roots and base of the plant. If you think you've rinsed enough, rinse it again. Leftover gel is basically an invitation for mold, and the crown of the plant — right where you trimmed those leaves — is exactly where it likes to hide.
Once the gel's off, give them a soak in water with a couple drops of iodine, Physan 20, or peroxide. This step's a game changer for keeping mold and rot out of the picture. After the soak, rinse them off in cool water so you're not planting them straight out of that solution.
Step 4: Pot Them Up
Time to get them in a medium. For Monstera we go with a chunky mix — sphagnum moss, perlite, or coco, or a mix of those all together. For everything else, peat moss plugs do the job. Plant just the crown of the roots, don't pot up the stem like you're putting tomato plants in your garden. Just the tip. (Insert grade school giggles here)
Step 5: Into the Leaf Lounge — Heat, Humidity, and Light
Now they go into an airtight container for full humidity. Here's the thing that trips people up: TCs can't stand heat when they're in the bag, but while they're acclimating they actually want warmth right alongside that humidity — so don't be shy about running it warm in there. You'll know the humidity's doing its job when you see condensation building on the inside within a day. Get some grow lights on them too; TCs need a decent amount of light while they're settling in, somewhere in the 8-16 hour range depending on your setup, here we actually do 24/7 full spectrum lights on our TC's.
Now here's where we get asked ... "What do we feed them? How do I water them?" .... basically, you don't. If there's humidity on your container, leave them alone. If it's dry, you can LIGHTLY water your substrate. Want to feed them? I'm a big fan of Clonex. You can use the gel form and dip the roots before planting, or dilute the concentrate in water and use that. Here in the Soil and Social Leaf Lounge we water with Clonex water for about the first 3-4 weeks of acclimation (IF THEY EVEN NEED WATER!!). REMEMBER, 99% of failures I see are from rot/too much water. you can lightly moisten and squeeze out your plug, or lightly moisten your substrate, but then put that lid on and leave them alone.
Step 6: Wean Them Onto Real Air — Slowly
This is the part nobody can give you an exact timeline for, because every space is different. Keep them sealed up for the first two weeks, then add a hole in the lid with a hot nail or heat gun, or start cracking the container for an hour every few days, adding a little more time each round. Over the next week or two you're working them up to living in open air full time. If a plant droops after you bump up their exposure, back off and give it an extra day before trying again — no need to rush it.
Personally, we vent here. We don't crack the lids. Our domes have vents, I will crack those vents, then the second vent ... then when they dry out ... I know they are using real air and utilizing water. So I personally recommend adding one hole at a time. If you want to take the dome off and do it that way, go for it. There's no right or wrong!
One thing worth remembering: don't judge a TC by its leaves. Roots and crown are what tell you if a plant's alive; leaves can look completely wrecked from shipping and the plant still pulls through fine.
I think of tissue cultures as baby humans. They don't want to be dirty (clean that agar gel off well!), they don't want to be wet (don't soak that substrate!), and they don't really DO anything cool until they get a few weeks older.
Every jungle's a little different, so treat this as a starting point and adjust based on what you're seeing in your own space. Questions? Come find us at a show or shoot us a message — we're always happy to talk plants.
People can be a lot. Enjoy your plants and go touch grass. 🌱
