How Far Apart to Plant Hostas?

Hosta is an energetic plant; some varieties are huge and occupy large areas in the garden. To avoid many transplants, you need to know how much space is required for a particular variety. Let’s figure out how far apart to plant hostas.

In general, plant hostas 1-4 feet apart. Plant small and medium hostas 1-2 feet apart. Large hostas plant 3 feet apart or more. 

If you plant hostas of different sizes, the distance between them should be equal to the width of the larger variety (mature size) plus two extra inches. Below you can find a calculator and table with detailed information on how much space is required for different hostas.

Miniature hostas

If you are a fan of small hostas, then you are in luck; on average, they have a width of 10-12 inches. For such a hostas does not need a lot of space. Plant them at a distance of 12 inches or a little more.

Compact varieties include the Mouse series of hosta. For example, Blue Mouse Ears, Church Mouse, Country Mouse. They are so tiny that you can grow them in pots in a small area.

Varieties such as Shiny Penny or Cherish are slightly larger but still belong to miniature hostas. They need more space, so plant them about 14 inches apart. Tiny plants are excellent if you have a small yard.

Miniature varieties:

  • Blue Mouse Ears
  • Praying Hands

Dwarf varieties

For dwarf hostas, a distance of 20-22 inches between the plants will suffice—the width of mature dwarf hostas is around 20 inches. Compact varieties include Stiletto, Fantasy Island, Fire and Ice, Frosted Frolic, Stand by Me, and many others.

All of them have such a size that they will be visible from a long distance, in contrast to miniature varieties. The advantage of such plants is that you can collect an extensive collection in a relatively small area.

Varieties such as Blue Cadet or Fantasy Island need a little more space; they are best planted at a distance of 24 inches from each other.

In a few years, even dwarf varieties will grow large enough sizes, so they have to be divided sooner or later.

Dwarf varieties:

  • White Feather
  • Fire and Ice
  • Fire Island
  • Autumn Frost

Medium varieties

Medium-sized hostas need more space than small and dwarf ones. Their width can increase by 40 inches, so you should plant them at a distance of 40-42 inches from each other. Such space will be enough for them to grow in one place for 4-5 years.

The middle hostas include Emerald Ruff Cut, Emerald Tiara, Eternal Flame, Hanky Panky, and Cherry Berry. Their size allows you to grow these varieties in medium-sized yards.

Varieties Hadspen Blue, Frosted Dimples, Tokudama Flavocircinalis need more space. The distance between these varieties should be 44 inches.

Medium varieties:

  • Halcyon
  • June
  • First Frost
  • Stained Glass
  • Golden Tiara
  • Gold Standard
  • Minuteman
  • Liberty
  • Great Expectations

Large hostas

Large hostas (width 60 inches) need a lot of space for full growth. The distance on which you need to plant them should be at least 62 inches.

Hosta Blue Angel, Elegans Spacing, Patriot, August Moon, Halcyon are large varieties. For them, you need to allocate a large part of your yard.

Varieties such as Tom Schmidt, Snow Cap need even more space; the distance between them should be 65 inches.

Large varieties:

  • Blue angel
  • Patriot
  • Frances Williams
  • Francee
  • Sum and Substance
  • Elephant Ears
  • Elegans
  • August Moon
  • Halcyon
  • Royal Standard
  • Wide Brim

Giant hostas

Giant varieties stand apart among all hostas, and their size is difficult to determine. To find out their maximum dimensions, you need to grow these plants in one place for more than eight years.

Giant varieties include Parasol, American Halo, Alex Summers, Empress Wu, Amos, Big Mama. Their width can reach 80 inches.

They need to be planted at a distance of 80 inches and not transplanted for more than 5-6 years for impressive size. Only then will they show all beauty and massiveness.

Giant varieties:

  • Empress Wu
  • Parasol
  • American Halo

What happens if hostas grow too close?

How Far Apart to Plant Hostas?

If you plant hostas too close, nothing terrible will happen. These are shade-tolerant plants, and they will grow even shading each other.

The consequences may be the compact size of the bushes. You will always have time to transplant them. If, for some reason, you can’t do it, you can trim the leaves a bit to free some space between plants.

If you do not transplant hostas for several years, they may become too dense. As a result, the risk of crown rot increases. They may also not have enough moisture, so you will have to water them more often.

As you can see from the photo above, my hostas are growing too close. This happened because I do not have enough space for them. So far, they are growing normally. I will have to transplant them soon.
