How to fertilize Crown of Thorns
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 Crown of Thorns after it doubles in size or once a year—whichever comes first.

What's going on? Can someone help me identify what the heck is going on? Could this be some pest thats causing my plant to curl and have these black and white spots?

I’m afraid it’s been overwatered. Plus with the furnace running, I also run a humidifier. How do I bring it back to health?

Purchased three Crown of Thorns about two months ago. Two have died and one is in the process. Leaves dry up and fall off! Is there anyway to save the third one? #Euphorbia

Does anyone know what’s wrong with my plant? I got this from Home Depot I haven’t repotted it yet I just sat it in a decorative pot near the window. But random leaves are yellow and falling off :( maybe too much water? #Euphorbia

I feel like I do nothing for this plant and it just thrives off of neglect. Plus, it always has new beautiful flowers coming in which is awesome

I took this plant the day of my grandmother funeral. These were her favorite plants she had and taking cuttings from her garden to bring back to my home 8 hours away helped me cope. This plant sat in water for a few months, rooted and I planted it into soil. Now there has been times where I thought it was going to die on me but it shows signs of improper care before it starts to die. This plant is my most prized possession.

You may have to move it away from the window at night if it gets frosty. It loves direct sun. But don’t water it during peak sun, the leaves could burn. It is from Madagascar, so make sure the soil matches. Good drainage and a terracotta pot works wonders. I had to bring back mine from the dead.

The plant does not tolerate soaked soil so make sure to prioritize drainage. It produces small, but vibrant and beautiful pink flowers and has done so regularly for me outside of winter time. The flowers and the leaves however are extremely brittle and fragile.

when i moved it to direct sunlight, at first the leaves dropped and it lost its flower, but it’s recovered after the shock. low maintenance, unless you really want to get a flower
