They’re such a dependable, ever-present a part of my spring, summer time, and fall backyard that it looks like watching pricey mates depart on a months-long vacation with out me. Don’t go!
We hyperlink to distributors that will help you discover related merchandise. If you happen to purchase from considered one of our hyperlinks, we could earn a fee.
Hostas, in contrast to me, have to expertise a interval of frost to develop and flower their finest.
So we don’t want to guard them from the chilly. However there are issues we are able to do to encourage wholesome progress subsequent 12 months.
Potted specimens want extra care than these within the floor. They’re a bit extra uncovered on the market.
Consider it just like the distinction between dwelling in a tent and dwelling in a well-insulated home – that’s how the roots really feel in a container versus the soil.
If you happen to want a refresher on methods to develop hostas, take a look at our information.
Listed here are the steps we’ll talk about to guard your hostas within the winter:
As with all perennials, your USDA Hardiness Zone and the plant’s Zone score dictate how it is best to care in your vegetation.
A Zone 4 to eight hosta cultivar grown in Zone 6 goes to want much less fussing over than the identical plant may if it was grown in Zone 4.
You must also maintain microclimates in thoughts. Each backyard has its personal microclimates, they usually can affect the work it is advisable to do.
In a comfortable spot shielded from freezing wind and excessive variations in temperature, you’ll be able to in all probability skip the mulching step, for example.
Some areas collect extra moisture, some are drier, some replicate warmth, and others keep colder.
Lastly, don’t assume that simply because your plant was advantageous final 12 months, it is going to be advantageous this 12 months.
Pests can construct up in numbers over years, a very harsh winter may trigger uncommon harm, or a plant may need been pressured within the earlier rising season.
Put together to adapt as wanted from one rising season to the following.
1. Take away the Leaves
If you happen to do nothing else on this listing, don’t skip this step.
Within the fall, often after a frost arrives, the leaves will flip yellow and brown, and can collapse right into a mushy mess.
The world gained’t finish in case you don’t take away the lifeless leaves and petioles, however you’ll be able to enormously cut back the prospect of pests and ailments discovering their approach into your hostas in case you do.
Plus, it simply appears to be like higher.
Eradicating foliage additionally denies slugs and snails a spot to cover out and breed. Meaning you’ll be coping with fewer mollusks subsequent 12 months. Hooray!
Get out a pair of scissors and lower off all the spent foliage at floor stage.
We usually like to attend till the leaves die again on their very own as a result of we could be certain all of the vitamins within the leaves have been saved up by the roots.
Toss the leaves in your compost pile.
However wait! There’s an exception to this…
In case your hostas are infested with nematodes, don’t wait till the leaves die again. As soon as they begin turning yellow within the fall, get on the market and take away them.
That approach, all of the nematodes don’t have time to exit the leaves and transfer to the soil and roots. This gained’t get rid of a nematode infestation, however it is going to assist to scale back it.
Eliminate the lower leaves fairly than tossing them within the compost in case you had an infestation or in the event that they have been diseased.

2. Mulch
Mulching is non-obligatory, however I strongly encourage it in areas the place the climate repeatedly freezes after which warms. The repeated freeze-thaw cycle can critically harm roots.
Mulch helps average the shift between temperatures and protects the plant’s roots.
Mulching is very useful for newly planted hostas, which haven’t had time to ascertain a big, strong root system but.
It’s additionally further useful for potted vegetation, that are extra weak to the consequences of freezing and thawing, and frost heaving.
Straw, leaf litter, shredded bark, pine boughs, or well-rotted compost all work properly as mulch.
I personally keep on with pine or straw as a result of slugs don’t appear to love them as a lot as they like leaf litter and shredded bark.
Use a couple of inches of mulch, and you’ll want to take away it within the early spring. If you happen to go away the mulch in place, it could actually smother the plant or trigger crown rot.
3. Cease Feeding
You’ve bought sufficient happening within the fall – don’t add pointless fertilization to the listing.
Hostas don’t want a lot fertilizer generally, however feeding within the fall can really hurt the vegetation and your surroundings.
Extra fertilizer may run off into areas the place you don’t need it, together with waterways.
It additionally encourages new progress proper when the vegetation needs to be placing themselves to mattress.
When you begin planning your Halloween costume, the children are again to highschool, and the leaves are simply beginning to flip, put the fertilizer away.
4. Divide Giant Crops
If you happen to didn’t do your division chores within the spring, now could be the time to separate up your hostas.
Earlier than you get away the shovel, water the vegetation properly in case you’ve had a dry fall. You need the soil to be moist and simple to work.
It’s simpler to divide them in case you do it whereas a few of the leaves are intact, however you are able to do it even after the leaves have died again.
If you happen to aren’t aware of the method of dividing a hosta, learn our information, which can stroll you thru the complete course of from begin to end.
5. Shield Containers
The simplest solution to shield your containers from cracking and your hostas from freeze-thaw cycles is to bury them within the soil, even in case you solely partially bury them.
If you happen to can’t or don’t need to do that, you’ll be able to transfer them in opposition to a wall or wrap them in burlap. You might additionally cowl them in pine boughs.
Keep away from inserting them someplace they’ll gather rainwater or snowmelt off of a roof or different construction.
The purpose right here isn’t to keep away from the chilly, so don’t take the pots right into a storage or shed. Simply shield them from repeated freezing and thawing.
The exception to that is in case you’re rising a hosta that’s on the border of hardiness in your area.
If you happen to dwell in USDA Hardiness Zone 5 and you might be rising a cultivar that’s hardy to Zone 5 in a pot, it is best to deal with it as if it’s rising in Zone 4 and tuck it right into a storage or shed to offer some safety from the chilly. At all times subtract one Zone for containers.
6. Mark Your Crops
I realized this one the exhausting approach. A number of occasions. If you happen to do any early spring planting, you don’t need to go digging into the roots of present hosta vegetation that haven’t popped up but.
Don’t cowl the world the place the leaves will emerge, however use a stick, wire, or one thing else that you’ve available to notice the place the vegetation are when you’re slicing again the foliage.
I’ll generally stick a tomato cage the wrong way up within the soil to mark a spot if I’m certain I’ll be digging round there and the plant isn’t in a spot that’s seen from my home.
Tomato cages aren’t precisely fairly, however they’re sturdy and huge sufficient to stop any main mishaps.
Be happy to skip this step if you realize precisely the place your vegetation are or in case you don’t have any spring digging plans.

Hostas don’t ask for a lot. They offer us dependable shade with out demanding a lot of our time or effort. However just a little care proper earlier than the winter units in goes a good distance.
Simply consider it as an funding in your vegetation’ future. You’re defending them from potential pests, ailments, and harm. And all it takes is just a little time and perhaps some mulch.
