You can use a simple spacing rule: most medium impatiens like being about 6–10 inches apart in a pot.

Quick Scoop

For a typical round pot, these guidelines work well:

  • 8–10 inch pot: 3 plants for a full, but not overcrowded look.
  • 12 inch pot: 3–4 plants is standard.
  • 16 inch pot: 5–6 plants if you want a lush, overflowing display.
  • 4 inch pot: 1 plant per pot.

A rough “rule of thumb” some gardeners use is one impatiens per 2 inches of pot diameter if you’re planting smaller bedding plants and want a very full look (for example, 5 plants in a 10 inch pot, 6 in a 12 inch pot), but you can reduce that by one or two plants if they’re larger starts or you prefer more air circulation.

What Changes the Number?

  • Plant size at planting time (larger nursery plants = fewer per pot).
  • Variety and vigor (some spread more and will fill in with fewer plants).
  • Your goal: tight, instant “bouquet” vs. more space for air flow and disease prevention.

As a mental picture: imagine each impatiens forming a soft ball about 8–12 inches wide over the season; you’re just giving each “ball” enough room to touch its neighbors without crushing them.
