Leaves rotting

#Hoya
Hi all, I'm new here. I have a Hoya Pubicalyx Splash that I got from a garden centre a few months back, but it's not doing well at all. The leaves are rotting and falling off at a rate of knots šŸ˜” what am I doing wrong and can I save it? It's in indirect sunlight (north facing), not very humid space. This is the pot it came in. Thanks in advance!
Last watered 1 week ago
How much light and water is it getting? Is it still in the same soil or have you repotted?
@MamaLinne it's not getting a huge amount of light, it's in a north facing position, but I might have given too much water. I've not repotted yet.
How often do you water them? Can you touch the soil and tell me if it’s wet or dry?

Depending on the window, North facing might not be enough light for your hoya. They like it much brighter, and if youve watered like it was in a brighter window then it won’t be able to use that water that fast. most of them enjoy humidity. But based on the look of the white fuzz on the soil and the state of the leaves, I believe you may be dealing with a root rot situation.

You will need to go in and inspect the roots, trimming off any that are black, mushy, or slough off to a light touch. After that, you can soak the root ball in a solution of 1 part hydrogen peroxide (the 3% kind) to 3-4parts water for 5 minutes. It will pop, bubble and fizz, which is good because it’s killing the root rot bacteria.

If you don’t have another fresh pot, wash this pot with hot soapy water, and repot with fresh potting mix.

Feel free to tag me @DreamMachine if you have any further questions!
@Moonlit okay, yes likely the root are rotting. I would repot asap in a very well draining mix- I use 1/3s of soil/perlite/orchid bark for my hoyas, but a standard aroid mix would be great too.

Unpot make sure to get every bit of that peat soil off of it. I pull off all that I can and alternately soak and spray with warm water (don’t let that stuff go down your drain. Check the roots and trim any brown, mushy roots off. Trim any brown or mushy stems and leaves. Repot (you can use that same one if you wash it out really well with soap and water) with the new soil and give it a good watering. Going forward, only water when it’s almost dry.

Hoyas like high light and humidity go thrive. It may not be getting enough- so I would say get a good grow light or switch to a brighter windowsill (I have some in east, others in south).
@DreamMachine haha jinx! šŸ«¶šŸ¼šŸŖ“
@MamaLinne I know right! lol šŸ˜‚ šŸ˜‚
@Moonlit I’d also take a couple cuttings off the ends to propagate just in case the mama plant doesn’t make it šŸ¤žšŸ»
@DreamMachine @MamaLinne that's so helpful, thank you. I'm going to get some of that soil ASAP! And take cuttings.
@debbiedo oh good call Debbie! šŸ™Œ
Less is more when it comes to watering this Hoya. I water mine roughly once every 3-4 weeks
Would this plant be ok in fine houseplant mineral substrate? Like the one sybotanica sell?
@Moonlit I’ve never done a hoya in a mineral substrate, so I couldn’t say. If in doubt, think about where the hoya lives in its natural environment. They are epiphytic or live in well draining organic soil. That’s what I would try to mimic at home!
@MamaLinne thanks so much
Maybe too direct sunlight
Just taken this out of the pot. It doesn't obviously look rotten but I'm no expert... Any ideas @MamaLinne @DreamMachine?
@Moonlit they look great! However I would strongly consider a smaller pot. Pot shouldn’t be more than 2ā€ bigger than the entire root ball, and hoyas especially like to be snug in their pots!
@Moonlit @MamaLinne I do see some signs of rot in that picture. Do you see all the tiny thin root centers sticking out of larger complete roots? It’s a type of bacteria that kills the outer layer, and you can tell it’s there when the outer root just sloughs off easily. You can treat and then repot in fresh clean potting mix. Mind your watering, and don’t water until nearly the entire pot is dry. šŸ™‚
Thank you šŸ™‚
@DreamMachine good catch! My old lady eyes didnt pick that up! šŸ¤“
@MamaLinne I only did because I just dealt with this last week or so when repotting my larger krimson queen 😬 I had put her in a way too big pot. Now I’m just hoping she pulls through šŸ¤ž
Peroxide bath done and repotted šŸ¤žšŸ¼
