Typically, you mulch to the drip line. I sometimes throw a thin layer a bit closer for the larger ones for esthetics. However, remember that one positive effect of mulch is to smother growth. I would not put a thick layer anywhere I want growth.

I will second the suggestion that pampering is not needed. I am zone 3/4 and do not winter mulch or cut the hosta down..I rake the dead leaves up when the ground thaws. Mulch=slugs in my world so I don't bother. Relax and enjoy them..nothing you do/or don't do will hurt them!!

i found.. too heavy a mulch.. too close.. interferes with watering ...

you want the mulch on the soil .. but when the mulch gets too dry ... you end up watering the mulch to remoisten it .. rather than it getting down into the soil ...

in the south there might be southern blight issues... if too close ...

also.. its a slug magnet ... places to hide during the day ... so again.. the further away .. the better ... etc ...

on might argue.. to leave the dead leaves there over winter.. if a plant is self mulching.. why remove it ... of course.. the reason to remove it.. is to get rid of slugs eggs ...

listen.. bottom line.. throw them on the driveway for winter.. most wont care.. except those that you pay more than 50$ for.. lol ...

dont over think it all ... and no more fert this time of year.. they need to be slowing down in fall.. not growing like crazy ...

Thank you all! I now realize I am over thinking hostas! :)

I put down mulch but kept it away from the drip lines. Most of my hostas are small (2 years old max, except for 6 of them) so there is a lot of open space in the bed. So the mulch is for aesthetics (it's a front yard bed). I know once they grow up I'll go to zero mulch, which will be nice.

Ken, very true about the driveway. I left a bag of hostas out on my exposed drive all winter and they sprouted out of the bag this Spring. Tough guys, that's why I love them!

My daughter-in-law has a spot in her lawn that borders a cement area. It receives mostly sun and it gets hot there, but surrounding trees are growing fast. In an effort to soften the look of the cement she planted hostas and daylillies but used our free pine straw as a thick mulch to retain moisture even though she did lots of soil prep. Three years later they are all doing great with the exception of one Montana Aureomarginata. Zone 4. They are mulched right up to the stems.

We like to mulch all our first-year plants after it freezes in our area just as a safety net. We had many dry years here so mulch was a necessity, even at the risk of breeding slugs.

Happy gardening! We'd love photos.

One reason hostas are so popular is they're virtually maintenance-free in a vast number of USDA hardiness zones. There's an ancient adage, "If it ain't broke, don't fix it." When I designed and planted my perennial beds, I researched the plants and once they were in the ground, I let them do their thing with nothing more from me than supplemental water when it got dry.

lol.. on driveway ... and overthinking it all ...

depending on your type of drip line.. i would put it on top ... when the hosta get larger.. it will disappear ... in the mean time.. keeping that mulch moist will add ambient humidity ... and if you had anything like our 8 weeks of drought.. it might have helped ...

have fun

When I first bought this house, the soil was very sandy. I planted hosta and other plants, and then added grass clippings in the summer and I'd pile shredded leaves on the beds in fall about a foot deep. The soil has improved, and the hosta are very happy. I now use hardwood mulch over the entire bed. I don't worry about it contacting the crown. Plant and water them when needed. They'll grow with or without us.

To Ken's point about watering. I have seen mulch become matted and it's resistant to absorbing water. I take a stick and break up the mat and that lets the water get to the plant.
