More information needed

Sorry they didn't post

ans what type of cacti is it I bought it from Walmart and it was on sale because looked dead but grew this piece of the top that's twice the size of the original now am I able to cut it off where it started growing from and have to of the cacti or what do I do. I have it supported now bc it's literally twice the size of the original plants and top heavy

This year I started a I guess cacti garden and they have grown wonderfully may have tovreplant them in bigger set up but curious as to what most of them are and if they should even be together as well

Hello, I am a newbie owner and I wanted to know what's the reason why the flower of my cactus turned like this? Is it overwatering? Too much sunlight or not enough sunlight? Your answers and advises will be highly appreciated. Thanks!!!

sorry here is the photo

Okay that is alot to take in. So the red dragonfruit one how do I get that to produce fruit its really budded up right now or will it? And which of the cacti need to be seperated becaause I am going to be repotting them bc they outgrew the container already. I live in Illinois so the summer is really nice atm for them but they will be inside for winter

And grafting I had no clue pretty interesting can you graft andy cacti together then?

In theory yes. But there are various reasons such as weight, vascular ring size, growth speed and even chemical composition, that give cacti preference to being grafted to some and not other(lophophora being more compatible to trichocereus than any other)..

So can it actually produce so called dragon fruit?

yes, you can...you can grow it from seeds (fruit purchased in supermarket). Or from said rootstok. It could grow quite big, should be staked and tied and needs lots of warm weather for fruiting. Greenhouse, or warm climate is best. Sharp spines...I used to cut of hard aerial roots off. They could grow from any spot on leaf (aerial roots), and get big. See THIS THREAD for photos...

So the plant i Have can and will produce dragon fruit

Is what I meant sorry

And I am very interested in grafting I just dont no how to go about which are compatiable honestly.

...plant you have could produce fruit under suitable growing conditions...
