Cancer Weed
About Cancer Weed
Cancer Weed is a popular houseplant 🌿 that is easy to grow and needs very little water to thrive. They do best in long-lasting, direct light ☀️ and should be less than 1 foot from a window.
Cancer Weed likes soil that is extremely well-draining. Your plant shouldn't need added fertilizers if you repot each time it doubles in size.
Cancer Weed belongs to the Euphorbia genus, and is native to Europe to the Western Himalayas, and the Mediterranean to Somalia.
⚠️ Cancer Weed is extremely dangerous if consumed. If you, a family member, or a pet has ingested any amount of plant material contact Poison Control, US (800) 222-1222, or your veterinarian immediately. These plants are not recommended for homes with children, cats, or dogs.

How to fertilize Cancer Weed
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 Cancer Weed after it doubles in size or once a year—whichever comes first.

I received my plant three days ago and I immediately put them in a container with just water. Since then they have grown roots. Do I pot them now? #Euphorbia

Why does my poinsettia have white blotches on the red leaves, almost as though some one has splattered bleach on them #Euphorbia

I bought a propagation less than 2 weeks ago. I noticed the discolouration a few days ago and took it out of the still wet soil. Has anyone experienced this and have a trick that works to save this propagation? #Euphorbia

Is it gonna die? I saw a post on Instagram that moon cactuses are just parasites and will die. Is my euphorbia cristata lactea the same? Is it just gonna inevitably die? #Euphorbia #PlantAddict #help

Looks like it’s gotten a pathogen infection. Any suggestions on what to do? (Outdoors in direct sunlight 3-5 hours a day, watering once about every week to week and half). Thank you in advance. #Euphorbia

What can I do to make the tar part get bigger? The base has grown and produced shoots off of it, but I want the sticky head to get bigger. What can I do to help it? #Euphorbia

I finally got one of my wish list plants today, Euphorbia Lactea or its common name ‘Ghost Cactus’. I’ve been wanting one for so long! They usually are pretty expensive so that’s why I hadn’t gotten one yet. Online & at local nurseries they go for about 50$ or so. But I found this one at Home Depot for 20$ & it came with a pot! I felt like that was a pretty good steal, & there was only one so it was coming home with me! I went for perlite, & this Home Depot was out too! This is the second store that was out of it. 😒 #HappyPlants #PlantsMakePeopleHappy #PlantAddict #NewPlants #SucculentSquad #SucculentLove #Succulents #Succulent #CactusClique #Cactus #Cacti #cacticollect #Euphorbia #ghostcactus #variegatedplants #GrowingSuccs #PlantTherapy
