Hostas are a popular perennial among gardeners everywhere. Check out this guide for everything you need to know about growing and caring for hostas.
Did you know that the average person has killed seven plants they’ve brought into their home? This fun fact comes to us courtesy of a study which also revealed that while plants are fantastic for mental health, the fear of killing a new plant fills many people why anxiety.
Are you feeling this way about a hosta you’ve recently acquired? If so, fear not, because caring for hostas isn’t as difficult as you might think.
Ready to make sure your hosta can live its best version of itself (aka not die on the window sill)? Keep reading to find out everything you need to know for taking care of a hosta like a pro.
Hostas & Sunlight
Most hostas are adapted to low light conditions and do best in shade. Originally, hostas naturally grew in the shaded loamy forests of Japan. Therefore, most common varieties do best in shade.
However, there are some hybrids that are adapted to either morning, afternoon, or even full-day sun. Take into account though, hostas still like moist, sheltered, and gentle environments as they originate from forest conditions.
Therefore, even if you have a hosta that’s been bred for sun exposure, make sure you don’t place it in a dry, exposed area where the sun bakes down all day—as it probably won’t like this level of exposure.
Lastly, if you have a colored hosta variety, these tend to do best in dappled shade, as the additional sunlight helps to bring out their colors.
Soil For Hostas In The Garden
When caring for hostas (or any other type of plant) one of the most important things to educate yourself on is what kind of soil they prefer.
Hostas typically do best in loose, loamy, rich soil, full of carbon and organic matter. They like their soil to be water retentive, but not too heavy or clay-filled.
If you have sandy or clay soil, you will need to amend this with lots of compost and organic matter to get it to a loose consistency, but still one that holds water.
When it comes to pH, hostas like soils that are around the 6.5 mark. However, while this is their ideal pH point, it is still worth planting hostas in soils that are slightly more acidic or alkaline, as they will most likely do fine.
Watering Hosta Plants
Another important component of caring for hosta plants is giving them the right amount of water. This is especially critical if they are in a pot.
Hostas like a fair amount of water, and tend to do well with a deep weekly watering routine. Deeper, weekly waterings will encourage them to establish a strong and sturdy root structure.
As a rule of thumb, you can try giving your hosta 2.5cm of water at a time, and scale this up or down depending on how they respond. Hostas tend to be more sensitive to underwatering than overwatering, so er on the side of more rather than less.
Fertilizer For Hostas
Hostas are relatively easy to fertilize. You can either choose to apply a balanced slow-release fertilizer, or you can apply a generous amount of compost to them every couple of seasons.
How To Plant Hostas
If you wondering how to plant hostas into the ground, start by examining the roots. If the roots or bulbs are very dry, it’s recommended that you soak them for up to an hour before planting.
Then dig a shallow and wide hole. Hostas don’t have very deep roots. Their roots mostly spread outwards and grow closer to the soil surface.
Thanks to their outward spreading root structure, it’s important that you make the hole wide enough that you don’t have to bend any roots against the side of it when planting.
Once you have placed the hostas into the hole, gently fan out the roots and fill in the soil, making sure the base of the plant is at ground level.
Add a generous layer of compost, taking care not to pile it against the stem of the plant. Lastly, give your newly planted hosta a good watering.

When to Plant Out Hostas
Hostas are best planted in early spring or early autumn. Keep newly-planted hostas well-watered, especially if they’re planted in the spring.
Mulching Tips For Hostas
One of the best gardening tips for hostas is to keep them nicely mulched. Hostas like moist soils, and mulching helps to prevent soil evaporation. It also mimics the debris that is naturally found on forest floors, provides an ongoing source of nutrition, and encourages the proliferation of beneficial soil microbes.
That said, when mulching hosta plants, make sure you aren’t packing the mulching up against the plant stems. If you do, this can trigger mold and other issues in the stems.
Hostas Outdoors vs Indoor Hosta Plants
If you love having plants in your indoor spaces, then you’ll be happy to know what growing hostas is possible indoors. Now that you know how to care for hostas outdoors, let’s take a quick look at what it takes to make them happy as indoor plants.
Because hostas can tolerate low light conditions, this makes them relatively well suited for indoor living. What’s more, forest floors typically don’t get a lot of air movement, making hosta plants more likely to thrive indoors than species that are adapted to lots of air movement.
If you are wondering how to grow hostas indoors, the answer is very similar to growing hostas outdoors.
Just make sure you pick a spot with the right amount of light and select a pot that is wide enough for the roots of your hosta plants.
Caring for hostas indoors isn’t hard, so give it a try if you feel like seeing that lush foliage gracing your living space.
Caring For Hostas: It’s Easy And Rewarding
As you can see caring for hostas isn’t that hard. What’s more, they can be incredibly rewarding plants. Once they get going, their lush and large leaves make a statement. Whether you plant them in the garden or as indoor foliage, one or two healthy-looking hosta plants are bound to catch the eye.
