It has been like this for a year now. It was in a low light place thus it became skinny but since I placed it in a very sunny window a couple months ago there has been no change. ....still skinny and doesn't look like it grew. Still green though. My bunny tried to nibble it a couple times bUT it wasn't too much. (Bunny is fine <3) so is it still alive?

Hello Nataly

Yes, your Euphorbia is still alive, though it is looking like it needs more sun. If you can, try to position your plant outdoors in more sun. It can take all the sun it can get, use very well draining soil like cacti mix with pumice or perlite. When temperatures are running high like in the 85F to 90F range, it will enjoy good thorough watering. So be mindful of ambient temperatures, if it is getting quite cold like just in the 55F to 60F range, lesser watering/delay watering.

But do feel your plant and check very well if there is any mushy part especially down there at soil level. It hates sitting on very wet media, so it is good to use some chicken grit or pumice to top dress it so the base of the plant is not left soaking wet for long.

My Euphorbia shows its active growth here during summer when temps are in the 85F to 95F range. So it is like a long period of waiting for it to wake up after I overwinter it indoors.

Showing here the growth activity it does when it is awake and finally enjoying the very warm and dry conditions in summer:

The stems look like they are wider than they were in the recent past (the skinny part about an inch or two down) which would suggest that yes, your plant is growing; and yes, it is growing differently (less stretched) now after getting more light.

If the plant can "see" the sun for hours each day, it's getting enough light. As long as the stems are green, it's alive.

Ok, since nobody seems to have noticed, ill point out the elephant in the room- i see blackened tissue on the tips of the center plant in photo 1, and the plant in photo 2. Since rotten tips could be an issue, thus i advise you, Nataly, to take a photo of them, bird view, and closeup, because im pretty sure thats the problem.

I'm not sure that they're rotten (but pictures would help determine that). The tips tend to dry out sometimes and sometimes die, or at least I've had that experience myself.

I would not worry much about those somewhat blackened tips, it is just looks like typical way some succulents appear when they are in dormant mode. Like if you have grown plumerias or adeniums totally lackluster tips when dormant. But once it gets more warmth and more light, the plant gradually wakes up and makes its new growth.

Once you see new growth, and temps are really warm, it will appreciate good thorough watering.

I would be more concerned if there is any part of that plant that is going mushy, that would indicate rotting.
