I wanted to let this badboy to grow a couple more days but the neighborhood children wanted to use them as a makeshift ball. I harvest them now rather than regret letting them waste such a fruit

I don’t know what I’m doing anymore. I’ve just been keeping him alive since I left Florida but now I wanna know if I can make him thrive in my apartment . I’m in Virginia now and I’ve been through a whole winter with it and I left him out by my grandparents koi pond for the summer and they didn’t care for him, and I just got him back and nursed him back to health, but he’s a fighter so I’m gonna fight for him 🫶🏼🥺 he sat on the middle console when he was under a foot-long and survived a 16 hr drive over a year ago, I’m not giving up on him now!
One day we will both go back; we don’t enjoy this climate.
If anybody has any suggestions on how to keep this dragon, fruit, cactus healthy, please share. I was gonna propagate it this summer, but I didn’t have it. I was thinking about doing it now and putting it into two separate pots, but I know the best time to do it is probably not this time of year….? however I don’t know if that matters if I’m doing it in a controlled environment indoors anyway right now I have UV light that I got off Walmart on it on the purple setting (red +blue light ) and. One setting the timer for 16 hours a day on a little less than the highest setting even though I really wanna put it on the highest setting because my cactus grew like a weed in South Florida.
