Late Night ~Cacti~ Appreciation Post, I had a chance to enjoy my #coffeewithsucculents this morning, & got to snap a few pictures of my cactus babies with morning dew 🌬️✨ 1. Tephrocactus Geometricus, also known as the ‘Dragon Egg Cactus’ , has been *slowly* growing. Recently these darker, more pointy, & thick spines have emerged… I’m not sure what that means or why the spines have seemed to get thicker than the rest of the spines on the plant. I’m interested to know if that means anything at all, or if it’s just a normal growth pattern. I haven’t changed anything as far as its environment. If anyone has any foresight on this please share! 2-4. Another close up of the Tephrocactus, & my BEAUTIFUL Arizona Rainbow Cactus… it’s very apparent why it was named such.. it’s became one of my favorites, I wanted one for so longgg, I’m so happy to own such a beautiful cultivar. The way the spines mimic a rainbow pattern vertically, as well as eyecactching aerial view in photo 3.. I just can’t get enough of this beauty. They also have stunning flowers which I hope I will eventually get to experience! 🌸 5. Variegated Corn Cob Cactus- it has really thrived since repotting in early spring, It looks to me it could already use another repot soon… problem is i have no bigger sized pots right now… (it’s a bittersweet thing when your plants used to be super small, so all your pots are small, but now you have had them so long they have almost trippled in size, however you are lacking in pots that are appropriately sized for them now… 😂). Anyways it will be okay till I can make it to a nursery for my birthday (November). 😂 I plan on treating myself to some plants and pots for my 25 birthday… 🤷🏻‍♀️ #HappyPlants #PlantsMakePeopleHappy #PlantAddict #NewGrowth #CactusClique #Cactus #Cacti #cacticollect #ArizonaRainbowCactus #CorncobCactus #TephrocactusGeometricus #SucculentSquad #SucculentLove #Succulents #GrowingSuccs #OutdoorGrowing #OutsidePlants #PlantLove

🧐 Troubleshooting

When troubleshooting a sad-looking houseplant, start by checking for signs of distress in its leaves, such as yellowing, browning, or drooping, which can indicate overwatering or nutrient deficiencies.

Inspect the soil moisture; too dry or too wet soil can cause problems.

Ensure the plant is getting the right amount of light, as too much or too little can stress it.

Finally, consider environmental factors like temperature and humidity, and adjust care routines accordingly to revive your plant.

😖 Common Issues

Overwatering is a likely cause of issues with Tephrocactus geometricus. These plants are very sensitive to wet soil so if you notice your plant becoming squishy or translucent, overwatering is the likely culprit.

Cut your plant just past where the rot ends and allow it to callus over for a few days before replanting it in fresh, dry soil. Download Greg to make sure your plant never gets overwatered again!
