How to fertilize African Milk Tree
Most potting soils come with ample nutrients which plants use to produce new growth.
By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.
To replenish this plant's nutrients, repot your African Milk Tree after it doubles in size or once a year—whichever comes first.

New African Milk Tree Just got this guy in today. Planted him in a big pot and slightly watered him. Anything else I need to do? I’m learning how to properly care for him as my last one died:( I live in NM, so I’m trying to learn and see if he’ll do better indoors or outdoors

My newest purchase Oscar. About 3-3 1/2 ft tall

My African Milk Tree is plump throughout the bottom of it but the top seems to be thin and I can’t find out why. Maybe it’s not a problem because it’s growing leaves again but I just wanted to make sure she’s okay

I'm so in Love with my oasis!!! ❤️❤️❤️

Hope everyone is having a good weekend, Im pretty busy this weekend! Today my grandma had a yard sale, so me & my boyfriend went to help as well as sell some things. We plan to use the money we made for our day trip to Carolina beach tomorrow! 🌊 I’m super excited since we haven’t been to the beach in a while & haven’t gone on a trip this year together. Although it’s not summer anymore and won’t be as warm, which means I most likely won’t be able to get in the water 😞 I’m still happy that I will get to see the water & sand as well as smelling the salt! 🏝️ My grandma was selling these plant stands & since I liked them she gave them to me. ( photos 1&3) she also gave me a pup from her Haworthia since I repotted it for her while I was there. 🌱 I also had a few plants I didn’t sell at the yard sale, so I kept them & repotted them when I got home. (Photo 2) its four polka dot props, & my bromeliad that wasn’t doing so well in the pot I had it in, so I’m hoping it will start doing better in a new pot & new spot. #HappyPlants #PlantsMakePeopleHappy #PlantAddict #NewGrowth #NewPlants #PlantShelfie #PlantStorageandDecor #PlantLove #SnakePlant #SnakePlantSquad #Haworthia #Propagation #PropagationStation #OutdoorGrowing #OutsidePlants #Bromeliad #PolkaDotPlant #SucculentSquad #SucculentLove #Succulents #Succulent #succulentsaturday #SuccerForSucculents #GrowingSuccs #Cacti #AfricanMilkBush

Cactus propagation I had a fall last night, my beautiful African milk bush fell from my porch rail onto the ground and AMAZINGLY ONLY lost two limbs, & the pot didn’t break! I was still sad but I know it could’ve been far worse so I won’t complain. 😫 I want to try to propagate the ones that broke off but im not sure the best way to do it. Should I stick them in some dry dirt and let them do their thing ? Do I let them callous first? Can I even prop these ? I’ve never propped a cactus before so I have questions lol.. 😅 please help a gal out 🙏🏻 #PropagationStation #Propagation #Cactus #CactusClique #Cacti #AfricanMilkBush #PropDontShop #helpneeded #GreggersSupportingGreggers #GregGang #Question #Succulents #SucculentSquad #SucculentLove #PlantAddict

Sharing my progress on my African Milk Bush, the first 3 pictures are from today, the fourth is from July, and the fifth is from May, I didn’t realize how scraggly it looked when I first got it, it’s really filled out and gotten taller, It’s easily became one of my favorites. 🤩 I’m a little worried about winter and how I’m gonna keep it looking so good since it gets a lot of light now, I’ll have to invest in more grow lights for sure 😬 #HappyPlants #PlantsMakePeopleHappy #PlantAddict #CactusClique #Cactus #Cacti #AfricanMilkBush #SucculentSquad #SucculentLove #Succulents #Succulent #succulentsaturday #GrowingSuccs #OutdoorGrowing #BeforeAndAfter #ProgressPics

Can someone please help me! My milk tree cactus is not doing good. It is not root rot. Idk if it’s the lighting or being spayed by gnat killer for indoor plants. #Euphorbia

Happy #FreshLeafFriday everyone!! Thank goodness the weekend is finally here. It was a longgg week. It’s been extremely hot, & on top of that the storms & rain have caused a lot of chaos in the area. I got to repot two plants today, the first photo is one of them, my Bromeliad. Its middle has changed colors from Yellow to an Orange-ish, Red color. It has 4-5 babies (second photo) that are getting bigger by the day, 😊🪴 I also got to repot my SOH but haven’t gotten a photo yet. 3&4. Waikiki Elephant Ears are doing great they have grown a lot since I got it, and have produced so many babies! I love the coloring on them. 🌿 5. My African Milk Tree is really starting to fill out, and seems to like its spot right now. It’s one of my favorite plants for sure. But it was NOT easy to repot that’s for sure 😆 #SucculentSquad #Succulents #Succulent #HappyPlants #PlantsMakePeopleHappy #PlantAddict #NewGrowth #FreshFeaturedFriday #AfricanMilkBush #Cacti #Bromeliad #repotting #OutdoorGrowing #OutsidePlants #GrowingSuccs

Happy Friday Everyone, we made it through another week! 😎 I got some new #Succulents yesterday & some new outdoor plants. I’ll be spending my weekend repotting them. I finally treated myself to some new plants, after not buying any at all since 2025 has started! Can you believe that?! 🫢😳 1. African Milk Bush (repotted this morning) 2. Sedum & Sempervivum Mix gifted to me from my mom. 🥰🌿 3. A second Ghost Fern because I gave my mom my first one.. and let’s just say it looks GORGEOUS NOW, so of course I had to get one for my house… 4. “Living Little Blossom” Hydrangea, -This is a compact type of hydrangea with dark green foliage, that has white blooms during peak of season. The blooms will turn a soft pink towards the fall (September). 5. Aloe Hybrid that was part of the succulent container, I got with a variety of succulents. No names were attached to the planter, so I have a few that are gonna need to be identified. @vvvelo - could you check the photos in the comments and tell me What you think they could be ? #FreshLeafFriday #FreshFeaturedFriday #SucculentLove #Succulents #Succulent #SucculentSquad #CactusClique #Cactus #Cacti #PlantID #HappyPlants #PlantsMakePeopleHappy #PlantAddict #RepotSeason #FernFriends #OutdoorGrowing #OutsidePlants #PlantLove

Beautiful plant that grows fast and easy to take care of with little maintenance. Perfect for an outdoor patio/balcony area with just enough sun to soak in. Mine has grown these amazing red leaves that have surprisingly stayed on throughout the colder months.
I would be a little cautious when handling it because aside from the pointy thorns on it, pricking yourself or getting it’s sap on you can cause annoying itchiness and discomfort. Please make sure to keep this away from pets or small children. If you practice care with this plant, it will certainly reward you with lots of growth and love.

I have had this old man ever since he was an inch tall he has grown to be almost 3 feet I’ve had him for many years. This guy is a great cactus and I love him to pieces. Easy to grow I put him outside in the summer make sure he’s got some shade on him because the sun is too hot here. I recommend one to y’a.

These cacti are great! They don’t need watering too frequently and are very tough plants. I will say that from experience these plants grow better in a relatively dry, room temperature place, and only need watering about once every 2-3 weeks depending on the temperature. These plants can grow very tall too, and they’re beautiful! Would definitely recommend for someone who’s new with plants!
