I just got this Hoya about a month ago from a local pottery studio. I think it's a carnosa but not sure, I think they were calling it Hoya jade. They got it online from a wholesaler & repotted it in this pot shortly before I picked it up. A lot of the new growth seemed kind of papery & unhealthy so I watered it after I got it home (older leaves were firm). I gave it another deep watering about a week later bc I didn't see much improvement. Shortly after this I had some leaves falling off & yellowing around the stems that were otherwise firm. I assumed overwatering so I haven't touched it since. Many leaves have fallen off, & some of the vines have shriveled up & look dead. I have other hoyas & it generally takes forever for them to show any sign of needing water, so this seems fast. Note: drainage hole is large so they put a paper towel in bottom to keep soil in. The soil in middle seems seems firm & peaty, so I think they just left original soil around roots & added regular potting mix to fill out the pot. Pot is hanging in a south-facing window, but weather has been cloudy/rainy lately. Thanks in advance for your help :)

I would bet your plant has lost a lot of roots. If the soil is firm and compact, your roots can't breathe. If it was me, I might repot it in a "lighter" mix with lots of perlite into a pot that barely contains the roots. I've lost more hoyas from over watering than under watering. It is a Carnosa--the all green variety sometimes called "jade." Good luck. Crossing Fingers!

Hi Pahri, Welcome!

Your plant does look like Wax Plant (Hoya carnosa) The soil appears quite dry and it looks like the vines are no longer viable. Even though you've used a terra cotta type pot, the issue is likely the type of soil being used. Hoya's need a lightweight growing medium, allowing for good aeration at root level and proper drainage. I use bagged potting soil and I add a lot of orchid bark mix and perlite, which makes a light, airy mixture that drains quickly.

Thank you guys so much. I went ahead and watered it shortly after I made the post since it was so dry. The better-looking leaves perked up and are firmer, and some of the droopier leaves have gotten more yellow. I'd really like to keep it in the pot if possible since that's what I bought it for, but do you think it'd be okay to change the soil now, or should I wait? I don't want to stress the plant out more since I know they repotted it before I got it, but I don't want to leave it if it's likely to get worse. Here's what it looks like now.

Does that pretty pot have drainage holes? It looks a bit large for the size of the plant but repotting again would likely cause additional stress to an already stressed plant. Your photo shows it hanging outside, is that where it will be staying? If so, hopefully it's an area where the plant will not receive direct sun.

The pot has a large drainage hole, they placed a paper towel over the inside to keep dirt from coming out. The plant is actually on the inside of the window, that pic is just at a weird angle. The window is south facing, but my house blocks the sun pretty well from the East.

I've been thinking again. Thinking Sometimes soil gets so compact that water doesn't penetrate the root ball and just runs out around the edges without actually soaking the plant. Could this be what is happening?

Heavy, compacted soil causes lack of oxygen and root suffocation. Hoyas require a light, airy potting medium.

This is my H. Iris Marie. Does anyone know why it grow but drops leaves?

Also. Does anyone know why my H. Bella grows like gang busters and grows peduncles, but drops the peduncles almost immediately?

I had Hoya 'Iris Marie' years ago but lost it to a freak winter freeze one year when I was out of town. What type of potting medium are you using? Usually, when leaves begin to drop on Hoyas, I suspect a lack of sufficient aeration at root level from soil that isn't draining quickly enough. Hoyas are epiphytic in nature, where the bare roots cling to the trees; they receive moisture when it rains and then dry very quickly. When grown as a container plant, Hoya's need a light and airy potting medium, the reason many of us use orchid bark as the main component of our potting media.

Regarding your Miniature Wax Plant (Hoya lanceolata subsp. bella) ; have you recently changed the location of the plant? Hoyas seem to like to be placed in a particular location and not moved. I've had it happen to a couple of mine over the years when I've moved the plant after the peduncles have formed.

Re: Iris Marie. A little more info. The leaves are not dropping after forming. They dry up before fully forming. I looked at my notes and and in April I wanted to see if living semi hydro would work better so I put its net pot in a self watering pot but not actually planted in it--sort of a transitional arrangement. It hasn't started growing again yet. It didn't drop any older leaves. The soil is damp and there are roots growing out of the net pot.
Re: Bella. That one has been in my east window since I got it in January. I've moved it around some but always in the east window. The baby peduncles form and then yellow and fall off. In April it was dropping leaves but I discovered it was a little too dry and started watering more. The leaves are better but the peduncles were still falling off. Sighing! It is continuing to grow peduncles.

The net pot sounds good for air circulation but if it's sitting in another pot that has water in it, that is detrimental to the plant. Hoya roots need air and if the soil is constantly in contact with water, even a small amount of water, oxygen at root level is depleted and the roots will suffocate.

I knew I wasn't being clear enough. The net pot isn't in the water. It's in the top of a self watering pot set. There IS extra moisture/humidity from the porous pot however. I just did that last month but the leaf shrivel was going on before that. At the time I wondered if I was under watering. Now I may be over moisturizing. Thinking

I water my Iris Marie more often than most of my other Hoya. I have lost the mini leaves that were starting to grow two times and both were because I let the plant get too cold. My husband has a habit of opening windows when it's cold outside Glare

I cut the vine at the point where it started to lose leaves. It wasn't that long ago, so I haven't seen yet if this will inspire the plant to grow a new stem.

My plant has three vines and two vines lost leaves. I am 100% certain that's why mine lost it, but I bet there are dozens of other reasons why it could happen. The third vine that didn't lose leaves is several inches longer than the other two even though they were all the same length when I trimmed them. It's grown like a weed.

This Verticilliata formerly Pottsii Chang Mai. See the yellowed spots on the leaf? And the smaller New leaf that's yellowed. Anyone know what this could be? It's under LED plant light and in an east window.
