I honestly am not sure what's causing the marks and dry tips. If it was getting a lot of sun it would be getting tons of red all over along with the black marks.

I'm wondering if it's soil issue. Does the pot it's in have holes? What soil are you using?

This is one of my Agavoides that I put out in a little too much strong sun to quickly. It started showing the burn marks in a day. Along with getting lots of red in a few days

This is not the same Agavoides, but this is pretty much what it looked like before I shoved it out into the sun:).

Thanks for the response. It is in a terra cotta pot with a drainage hole. Cactus soil with a bit of perlite added. I have a moisture meter to check soil. Honestly I have been watching to make sure all is well because it is my favorite succulent. I have been trying to find a photo with similar markings but no luck

Black lines seems like burnt marks. Are these windowsills grown? Sometimes windows can amplify intense sunlight and scortch plants. The dry tips are signs of thirst. You just need to water them more and provide more fresh flowing air. Stale air and restricted water stresses plants like yours if grown indoors.

It's funny you post this. Yesterday I noticed my biggest Agavoides getting yellow translucent leaves. Usually a sign of overwatering, but that is one thing I cannot be accused of is overwatering. Underwatering yes under no:).

So in a panic I unpotted it. What was happening the water was not draining. So it was beginninng to rot. I've watered it once a month in the past two months. So that's twice in two months. It was in a big glazed pots. I have a hard time with moisture issues with these big glazed pots. The glaze/paint doesn't allow the water to evaporate. I'm glad I did this because I would have lost my plant to rot.

I think I see some translucent leaves on yours. Could be the pic tho. If this were my Agavoides I would unpot and check the roots. Sometimes you can't tell what's going on with the plant until you see the roots or what's going on in the pot. Check if the soil is still wet. Do a complete check. If you see any yellow translucent leaves take them off. I would clean the plant up and give it new mix. Do a mix of at least 50% perlite with 50% C&S soil. I would plant the Agavoides a little higher up in the pot too. Don't water for a week.

Keep me updated I'm curious.

Thanks, I have been keeping it outdoors, slowly acclimating it to sun.

This is gonna sound crazy, but could something fallen on it? Anything from paint to something hot.

Kara I will completely redo my plant..repot, new soil. I have a problem with my plants not drying out quickly enough because of Minnesota weather..it has only been in the past week I can leave them out. Most are in terra cotta pots. I am concerned it has a disease..I will keep you posted. Thanks

If you have issues with humidity I would definitely do 60-70% perlite.

this is a better photo

Kara, as my follow up...my echy lipstick plant repotted. Added more perlite to the soil and have not watered it in a week. The pot below was the original pot and even though the soil was dry on the top half. The soil at the bottom was like sludge and would not dry out even with the drainage hole. It has been a week, just wondering when I should water?

Yep you can water. The new pot is much better. The older one was not draining. I have pots like that. Even there there are holes. The moisture does not escape. That's exactly what was happening too my huge Agavoides.

Love to see a photo of your agavoides plant. So much for my glazed pots. Think in the fall I will repot in terra cotta pots before the long Mn winter

Here is a pic of my sick Agavoides. Same thing happened with mine the water wasn't draining. Stupid pot;)! It's lost some of it's size because I had to remove a bunch of soggy leaves:(.

It started getting a couple yellow leaves like this. So I pulled it out of its pot asap! I found damp soil at the bottom:(. It was healthy one minute then started going south quickly. I think it should make a turnaround. Luckily it still had some roots:)!

Here are some other Agavoides I have. I think what was once my biggest is no longer:). I keep mine on my porch so no direct sun. So that's why they're all green:).

An Agavoides Ebony that is clearly not getting enough sun. Today is the day I will start acclimating him to more sun. So he can get those dark edges:). A little story with this guy. A couple years ago we recieved hail for about 30 seconds. Let's just say ice got stuck in between some leaves. So my Ebony began to rot. It's been two years and I think he's in the clear. I've kept him in the shade while he grew. I had to remove sooo many rotten leaves. The hail made him go from about 8 inches wide to probably about 4 inches wide.

Last thing. Sorry for the overflow if Agavoides. I just think they're so pretty:)!

One of my favs my Agavoides crest:).

Here's the pot it was in. Pretty but keeps the moisture. It's crazy because it's been in that pot for two years.

3 holes just weren't enough I guess.

Kara, THANKS for the advice..very helpful. Your agavoides look healthy. It's such a challenge to give them sunshine without burning. I saw a photo of the lipstick plant and thought it was so beautiful and searched everywhere for it. A couple of times I thought I had found it but turned out to be a different variety so I ordered it online. I was babying it so you can imagine how disappointed I was when I saw what was happening. I panicked! I'm a gardener of flowers so this is all new. The glazed pots are so pretty but I think I'll be gradually changing to terra cotta. You seem so knowledgeable you must be really experienced in succulent gardening. It will be fun to see your agavoides after a month in the sun

Thank you Carol for such nice words. I will keep you updated. The secret for giving them color. Is doing it slowly no rush. If you rush it they will burn, but will get red. Do it slowly they will get red with a lot less scars and marks:).

It is unfortunate that those glazed pots don't evaporate the moisture as quickly. They're so much prettier, but it's not worth it. You'll have a pretty pot with a dead plant;). It's strange because it doesn't always happen fast, but I have noticed over time my succulents that are in glazed pots usually something will go wrong after awhile. Maybe I just haven't figured out the secret yet;). Like I said my Agavoides was in the pot for two years. Then all of a sudden it stops draining. With 3 holes too.

Keep me updated with how your Agavoides grows:).
