Definitely let the soil dry out between waterings. You can rot the tuber keeping it to wet, especially when young, before the roots have had a chance to really develop.

your outdoor soil temps should be about 60 Fahrenheit (15.5 C.) when you plant out.

And yes - usually if you take a cutting, another shoot or two will pop up. Though usually cuttings are taken close to the tuber, and yours is already planted.

Well I would have planted it already in its permanent spot, if you know it already, but since you have confirmed it's a good a root then I think you can move it now while it is still fairly infant.

I would not take a cutting of this shoot specifically. Wait until it has grown a bit, then take a cutting off its stems or even the top of the growth if you want to promote side branches.

By letting it grow and produce food for the plant, you will get many more branches and possibly even additional shoots without stressing out the one tuber that is trying to regrow based on its own stored energy.

thank you both, soil is at 9ðc in someplaces and around 13ðc in others, I planted (wilkos (local basic home diy store) ones that are basic colours for cacti one's for a pound, and they have not sprouted yet they was planted about month and half ago.)

I will let them grow more before taking cuttings.

the spot is going to be along that fence that gets Sun all day everyday even in winter (but I'll dig up for winter)

thabk you Leo
