Hostas are hardy perennials that hardly ever need special care and are ideal for gardens that don’t receive a lot of sun. Hostas are dependable, simple to grow, long-lasting, and might even outlive the grower! Learn more about hosta maintenance and growth.
About Hostas
The variety of sizes, heights, textures, and colors available with hostas is neat. They work well in a wide variety of environments (patio, border, container, rock, shade), and they are also cold-hardy.
Although larger or smaller kinds are easily accessible, the majority of varieties have a spread and height that typically range between 1 and 3 feet. A few examples of leaf hues are blue-green, lime green, and variegated white. Hosta leaves come in a variety of shapes and textures, from thin and smooth to ridged and heart-shaped.
Despite being mostly recognized for their gorgeous leaves, the plants also bear lovely pink, lavender, light blue, or white flowers from early summer to early fall. The flowers are adored by hummingbirds and other pollinators, and depending on the type, they may even be scented.
Notably, deer, rabbits, slugs, and snails all enjoy hostas almost as much as people do. Keep in mind that deer will readily graze a hosta patch down to merely stems if they frequently stray into your yard.
Due to their huge leaves, hostas do not fare well in direct sunlight; instead, they thrive in dappled or partial sunlight, though they will even grow in deep shadow. Once planted, they can tolerate brief droughts and the summer heat.
Hostas prefer fertile, well-draining soil (amend soil with compost or rotted manure if your soil is poor). Plant them at a higher spot or somewhere where the earth doesn’t stay moist because they don’t like to sit in wet soil (especially in winter). Hostas are forgiving in this regard, however ideal soil should have a pH between mildly acidic and neutral (6.5 to 7.0).
When to Plant Hostas
- Purchase hostas as dormant, potted plants, or bare-root divisions, then plant them in the spring or the fall.
- Hostas can be planted during the summer growth season, but they will require extra care (mainly watering) to prevent summertime damage.
How to Plant Hostas
- Make a hole that is twice as wide and deep as the plant’s root ball. The hosta’s roots will spread outward and benefit from loosening the soil in the planting area.
- If you’re planting many hostas, distance them apart based on how big you think they’ll be when they’re mature. Hostas are good at covering bare spots!
- Place the plants in the hole so that their crowns, or bases, are level with the surrounding soil and that any leaf tips that are just beginning to emerge are visible at the earth’s surface.
- If purchasing hostas in pots, plant them with the same depth of soil.
- Water the area surrounding the plants until the soil is moist to help the roots take hold.
How to Care for Hostas
- After planting or when spring growth starts, use a well-balanced, slow-release fertilizer.
- Keep the ground damp but not drenched.
- Consider adding mulch around the plants to help maintain moisture if the soil tends to dry out rapidly, but keep in mind that mulch can serve as a slug hiding place.
- After blooming, remove flower stalks to promote fresh growth.
- Let hostas grow until they begin to suffer from frosts since many of them have attractive fall color.
- Hostas will flatten out and become mushy in the late fall after a few frosts. We advise thinning them out to prevent slug and disease problems. Brown leaves should be removed from the area around the plants. If time is of the essence, you could postpone the pruning until the next spring.
- The optimal time to divide and transplant plants is in the early spring when the leaves are just starting to sprout.
Transplanting or Dividing Hostas
Hostas typically don’t need to be divided for health reasons. They will simply develop more slowly if they have less area. However, it is ideal to divide a hosta in the early spring when the “eyes” or growing tips first appear above ground if you want a more orderly appearance for your garden. A hosta can also be transplanted or moved at this time to a different location.
For each crown or plant, keep as much of the root attached as you can. Place the fresh hostas in the same depth of soil as the old ones. Up till establishment, water well.

You’ll discover that once you start learning about hostas, they become quite addictive! There is a hosta variety to meet any situation, from broad borders to little rock gardens, ranging in size from 4-inch micro hostas to 6-foot-wide enormous hostas. Here are a few examples:
Do hostas grow indoors or outdoors?
Hostas are lovely, shade-tolerant plants with waxy, emerald-green leaves that come in a wide range of hues. These rhizomatous-rooted perennials are normally planted in the spring or fall and mature in about five years. Hostas are often planted outdoors, but if grown in pots and under ideal conditions, they can also make excellent houseplants. Hostas require a yearly dormant period in cool circumstances, unlike the majority of other houseplants, in order to survive. Hosta can be a more carefree plant inside, where it is less prone to pests and illnesses, if you can meet its demands.
Hostas are harmful to dogs and cats if consumed, so take care where you grow them indoors.
Do hosta plants grow outdoors?
Hostas are a tough and adaptable plant. Zones 3 through 9 are good for growing this perennial, and it requires little upkeep. Hostas, which are frequently thought of as shade garden plants, can also do well in containers. A hosta is a great addition to a balcony, porch, or patio area because of the numerous green and yellow hues and leaf variants. It would be prudent to grow a hosta in a container if your garden area is prone to slugs.
Can hostas endure the elements?
As gardens get smaller and breeders create compact kinds, using perennials and even small shrubs in containers is becoming more and more popular. Hostas are one of the perennials that thrive when grown in small containers. They are the ideal plant for busy or disinterested gardeners because they are available in thousands of cultivars and require little maintenance.
Particularly mini-hostas enjoy the constricted spaces of a container and, when grouped together or combined with other little plants, can look extremely lovely on a porch, patio, or stoop. However, hostas of any size can be cultivated in a container.
Hostas can be grown in pots with only a few considerations. First, considering the mature size of the plant, most experts advise choosing a pot that is on the smaller side. Less than 3 inches should be left between the hosta’s roots and the container’s edge when you plant it. Although a small container could necessitate more regular waterings, it’s ideal for the plant’s general health.
As with other container plantings, ensure that there is adequate drainage. After a thorough soaking, the water should freely drain out of the bottom of the pot. By drilling a few extra holes in the pot, you can have good drainage. It is preferable to completely water the container less frequently rather than providing the plant with only a small amount of water each day. But regardless of the weather, if it’s hot or particularly dry, you’ll probably need to water your container every day or two. Hostas have the advantage of not immediately drying out and dying when they become dry. Instead, they will wilt slightly. Your hostas are requesting water if they are withering. When it comes to hostas, overwatering increases the danger of crown rot.
Use regular potting soil (never garden dirt) and water the plant thoroughly when growing hostas in containers. Some growers advise using quick-draining soil. Outside, place the container in a partially sunny or shaded area. The majority of hostas enjoy dappled shade or a little early sun, while some can tolerate heavy shadow.
Although it’s possible to overwinter hostas in containers, it’s not as simple as doing it in the garden. In actuality, some people will bury their container hostas for the winter. Other gardeners bury their pots outside, just like a garden hosta would, so that the roots are buried. The pots could also be placed in a fairly protected spot (along the side of the house, etc.) and covered with a thick layer of mulch. But if we get a particularly harsh winter, that could be challenging. Bring the pots inside an unheated garage or shed once they’ve gone dormant is a final option. However, to prevent the soil from sucking water from the dormant roots, the plants will need to be watered a few times throughout the winter. Do not attempt to overwinter hostas as indoor plants. They require a period of cold, dormancy.
Where do hosta plants thrive?
With a selection of exquisite hostas, you may brighten a dark spot in your yard. These leafy perennials add color and texture to garden beds while requiring little maintenance to maintain their good looks. The decision of which type of hosta to cultivate may perhaps be the most difficult.
Where to Plant Hostas
Choose a location that receives some to all shade if you want to plant hostas. Although most hosta varieties can tolerate early sun, they prefer a dark environment. It’s crucial to understand that these perennials thrive in rich, nutritious soil that has plenty of organic materials. Hostas shouldn’t be planted in dense clay soil since it won’t provide adequate drainage. Place hostas where snow tends to accumulate in places that receive a lot of snow in the winter to preserve stems and leaves.
What Kind of Soil to Use for Hostas
Mix 3 inches of Miracle-Gro All Purpose Garden Soil with the top 6 to 8 inches of soil in the bed for growing hostas in planting beds to enrich and improve the current soil. Some gardeners choose growing hostas in pots. Warmer regions with mild winters are where this works best (zones 7 and warmer). Fill pots with Miracle-Gro Moisture Control Potting Mix when growing hostas in containers to help prevent overwatering and underwatering.
How to Choose Hostas
Hosta species occur in a wide variety of hues and patterns, and the size of the plants can vary from tiny to enormous. Green, gold, white, blue, and silver hues are available in leaves, either as solid colors or in varied patterns. Hostas are typically grown in gloomy settings by gardeners, however certain varieties may withstand brief periods of exposure to sunlight (though they still need protection from the hottest afternoon rays). Actually, the sun is necessary for the rich hue of gold types to develop. Hostas can be cultivated anywhere in the country because they are hardy in zones 3 through 9.
The best seasons to plant hostas are early spring or early fall (as soon as the summer heat subsides), and if your region has a rainy season, before it. There are several sizes of hostas. Check the plant tag to establish the proper spacing in the garden. Most hosta varieties, with the exception of the smallest, require a few years to reach their maximum size, so it’s crucial to give them adequate space to develop. Plant it so that the root ball is buried in the soil at the same depth as it was in the pot. After that, make sure to water thoroughly.
How to Plant Hostas in Containers
How big of a container you need depends on how big your hosta gets. Use a pot that is generally at least 2 inches bigger than the one the plant was shipped in. Be careful not to overwater a hosta if you plant it in a pot that is several times bigger than the one it arrived in. Root infections can thrive when roots are moistly retained for a longer period of time before they are firmly established. Once you’ve decided on a container, proceed according to the above-mentioned planting instructions.
How to Water Hostas
Providing hostas with constant moisture is crucial throughout their first growth season as they establish themselves. When the top inch of soil is dry, check the soil once a week (more frequently in the summer). Except in times of drought, hosta plants can typically thrive on rainfall once they are well-established. However, when growing hostas beneath trees, tree roots often scavenge any available moisture, necessitating watering. The same is true for larger hostas, whose leaves have the potential to build a canopy that blocks any water from reaching the ground by shedding it above (and their roots).
How to Mulch Hostas
Put down a 2 to 3 inch thick layer of mulch after planting the hostas. Since the mulch prevents weed development and sunlight access, this will aid in preventing moisture from evaporating and weed growth. Scotts bagged mulch, chopped leaves, pine straw, or any other locally obtainable material are all suitable mulch supplies.
How to Feed Hostas
Hostas require a consistent supply of nutrients throughout the growing season. Following the instructions on the packaging, feed them with Miracle-Gro Shake ‘n Feed All Purpose Plant Food a month after planting. Your hostas will be nourished by this for up to three months.
The removal of wasted flowers is an important aspect of hosta maintenance. Even while it’s not essential, this chore does make plants look their best. After all the blooms have faded, cut the flower stems off at the base.
When cultivating hostas, the main pests to watch out for are slugs, deer, and rabbits. Use Ortho Bug-Geta Snail & Slug Killer or pet-safe slug baits and traps to control slug infestations. When dealing with four-legged creatures, try using bird netting to cover specific plants or a spray repellent like Tomcat Deer Repellent, which includes essential scents that animals find repulsive.
Autumn hosta leaves deteriorate and fall to the ground. To reduce the number of places slugs and other pests can hide throughout the winter, remove fallen leaves once they have completely collapsed. During the winter, plants go dormant and don’t need any extra attention.
How to Divide Hostas
Hostas often grow best when given room to expand. Many hosta types take up to five years to even reach maturity. But when they’ve grown, you might want to separate them.
Hostas should be divided in the spring or early fall, before the season’s rainiest period. Merely pull up any little plants that have grown around the main clump and replant them if you simply want to duplicate your plants to scatter about your yard. Uncover a massive cluster by pulling off as many roots as you can. To obtain enough root mass, you might need to dig down 18 inches with a huge hosta. Put the plant on a tarp and cut it into smaller pieces using a knife, a spade, or your hands. Replant the parts using the aforementioned recommendations.
How to Use Hostas
Grow hostas in your yard to give an attractive shade planting and to entice hummingbirds. An effective ground cover or hedge can be created by planting several giant hostas. A row of hostas can be used to edge a driveway, soften a tree, or skirt a fence. In a shaded garden, small varieties of hostas make good edging plants.
Hosta leaves are a beautiful accent to bouquets of flowers from the garden. Try arranging the leaves in a vase if you are growing hostas with various leaf hues. Hosta flowers, especially the fragrant varieties, give indoor spaces a lovely scent. It is better to harvest flowers when at least half of the buds have opened because the flower stalk blooms from bottom to top.
