I purchased these recently and within the first few days they got these marks. They were put at the front of my house near a brick wall and in full sun.



And this is my Hot lips succulent has it had to much rain or sunburn?



I have never grown any of these plants before and need all your help
I thank you in advance for any assistance you can give me.

And to everyone who has written anything on this forum - It is such a wealth of information
I have spent days reading everything, thank you, thank you, thank you! As stated, I have
never had the opportunity to grow succulents/cacti, but fell in love with the plants during trips to Texas/Mexico.

Looking at your location and the fact they are new plants I would suggest this is sunburn. New plants regularly get sun damage for a few reasons. First, due to them coming from a location (nursery) where they were grown under shade cloth/in a green house. A less common is simply due to the plants position, if the plant was facing south for a season or two and now it is facing north the part that was not exposed to sun will be more susceptible to damage.

Cacti generally build up a tolerance quickly but too much too soon will cause this damage. Don't worry they should recover with no problems, just keep the affected areas dry for the next week or so.

Welcome agavewoman, you sound like me, read everything and thanks to wooddragon, here I am out of the shadows!

I have to agree 100% with HN. The Euphorbia (trigonis?) is definately suffering from sunburn and I recognise it from my own experience (the brown patches, 'scars', are probably there to stay unfortunately).

Glad to hear you are trying some Lithops. I love them. They take up very little room and there is such a variety in colours and patterns that it's very hard to get bored with them.

Hi agavewoman i have some Euphorbia trigonis which like a bit of shade, maybe only morning to mid morning direct sunlight, and they stay green and keep their leaves at the tips... you could prune out your sunburnt stems ,as i see you have quite a clump in each pot...
