Hostas are beautiful plants and they come in many different varieties. Some are tiny and some have huge leaves. By summer they produce flowers and once the flowers fade you can cut back the flower stalks.
By late fall the leaves will fade and you will have to flush cut all of it. Then you can look forward to next year.
By far the biggest mistake I see with Hostas is their placement. Hostas are shade plants which is why they are placed in a corner on my humble patio. Out in the open sun they suffer.
Hostas are perennials so they pop up every year. All you have to do towards the end of summer is cut back the flower stalks. Then, once they leaves start to fade in the fall, you can flush cut the entire plant.
Hostas are great plants but make sure they have shade!
