Oof. I can see from these pics what you mean. From my experience with miniphals, they're more delicate than your bigger boys. You have some really nice green roots on the first pic, but only a few. The air roots look good and reaching away from the plant, which can sometimes be a sign of the medium being too wet/too tight for these little babies. I agree with camille that since the new one was recently purchased there probably was some damage prior to your repotting it, however if the medium was continuously too wet it didn't do it any favors.

You have to understand that because their structures are smaller, their care can be a bit more delicate..Sometimes they can't handle the same watering schedule as the bigger phalaenopsis. You have to look for signs of wanting water, such as silvery roots or touching the medium and feeling that it's drying out towards the middle.

My environment is also dry and cold ( we've been having a cold and wet week lately too) so that's why I wanted to share.

As for what to do next, I defer to the experts of this board for their seasoned advice!

Thank you Camille! The bark I have them potted in is small pieces. I have to say that even though Iím in the north we have to take into consideration that itís not warm here yet. Temps are in the 40F to 60 F range so my heat is still on so the air is very dry in the winter here. The roots on the new little phal were in good condition when I repotted her as soon as I got her. There might have been one or two roots already mushy that I removed but the rest were fine

Thank you Phalenoptics! I can see the bark through the sides of the slotted pots and I water when the bark looks very dry. On my two big girls, I water them once a week by soakin for 5 minutes or so then drain and theyíre doing great. The little ones Iím finding very hard to manage. I think Iím going to try Camilles suggestion of putting them in a plastic bag for a month or two and see how it goes. I assume I leave the top open?

It might be good to diagnose the cause of root rot so it doesn't happen again! Especially if your new phal came with healthy roots and now seems to be struggling.

How hot is it in your house with the heat on? How low does the temperature drop at night?

Also, sometimes if your house environment is very dry, the outside bark might be dry on the surface, but inside the middle it might still be wet.

Figuring out the cause of the root rot will help you know how to adjust your care, and also help those of us who want to learn

Itís stays a constant 68-70f in my house day and night but outside it is around 40-60f during the day and 30-40f at night. Iím not sure how to diagnose the root rot. Sometimes I think they just dry out quickly and itís more that the roots are getting too dry and other times I think itís root rot. Iím just not really sure to be honest. I just love these little phals and want to help them to be healthy. I love my big phals to.

Yes, I didn't expect you to diagnose it! That's why I'm asking more questions, to see if we could figure out what could possibly be causing it 🤔

When you say you thought the roots might be getting too dry sometimes, were you looking at the aerial roots or at the ones in the pot?

Do you use air-conditioning? AC can dry up the air to the point that plants, especially orchids, are affected.

In terms of deciding when to water... can't really be prescribed by the calendar - your conditions are different than mine are different than other people's...An approach to consider, weigh the plant after watering, using a postal or kitchen scale. Then do it the next day, etc. When the rate of weight loss starts to decline (not much more water to lose), then it's time to water again. So the plant gets to the point of being barely damp... not bone dry but not wet either, then repeat. After a few times you'll get a feel for what is needed in your environment with your medium. Then you don't have to guess what is going on in the middle of the pot, the numbers will tell you what you need to know.

Thank you Roberta. I can try that. In the winter here the air is so dry because of using the heater but in the summer when it gets really hot, weíre wall humid so itís hard to regulate. I did put both mini phals in plastic bags itís the tops open. Iím going to see if that helps in case they are too dry.

Yug , itís not anywhere near air conditioner here yet since Iím in Maine and itís still very cool here. In the hot months of summer I may use the air conditioner a couple weeks out of the whole summer. I only turn it on when itís really hot and humid because I have trouble breathing in that climate.

I'm only speaking from my experience in my conditions, but I've found that slotted pots under 4in in size to be rather tricky to water correctly, especially in low humidity winter conditions.

I've either repotted those into standard transparent pots (I don't see the purpose of slots in small pots, as those are already rather fast drying compared to large pots), or take the entire thing and slip it into a slightly larger transparent pot, as a sort of cache pot. The advantage is that you get the fast even drying from the slots, but the other pot maintains a more humid atmosphere around it. This works quite well for me.
