    In my experience it is best to divide hostas in spring, just as their bullet noses are appearing above soil level.   Water well, lift and then divide with a spade or an old bread knife depending on size.  Spares can be planted elsewhere or potted up and grown on till you decide where they should go or offered to/swapped with friends and neighbours.

    Doing it in autumn, when they are going dormant, can lead to them sulking and even dying.

    You can divide them in autumn or spring. If you do it in autumn it is best to do it before cold weather sets in, a mild damp day is best. I have never had a hosta die from being divided in autumn.

    Mine hasnt gone dormant yet. It is in a pot and all leaves are fully green. Weather here is like high 14 low 6 types. Does it seem all ok to divide?

    That sounds OK to me.

    One thing I would say is, if  yours still have lots of foliage, and you don't want to wait until it's completely died back, it's worth cutting it back a bit. Easier to see what you're doing, and also easier for the plant to establish again. It may even produce a little more if you're in a very mild area.
    They're tough though, so it shouldn't be a huge problem.  :)

    I divided the hosta today. It wasn't separating so I did a bit of operation with knife. Fingers crossed 🤞

    Will update later in season how it goes. 

    Thanks again for your help.

    I usually use an old bread knife .., I’m sure your Hostas will soon double in size. Just give them lovely new potting compost and they’ll be happy as Larry.
