How Far Apart to Plant Hostas (Calculator)


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.

You need to plant medium hostas 40 inches apart. Dwarf varieties need 20 inches of space between them (center to center). If you have large hostas plant them 60 inches apart. 

Giant hostas should be planted 80 inches apart or a little more if the bush is too big. And miniature hostas need to be planted 12 inches apart.

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.

What happens if hostas grow too close?

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. You can learn more about how to grow hostas in my article –Planting Hostas.
