Beginner Gardening: Oregano & coneflowers - together?, 1 by etnredclay

I'm reclaiming an abandoned garden -- abandoned by me 6 years ago. After clearing out the trash and volunteer trees, I found a huge patch of oregano (4'x8') next to another huge patch of coneflowers (6'x10') all of which came from 2 plants each -- yeah.

They spread and survived on their own -- but the coneflowers are not blooming well even after general fertilizer this spring.

Any thoughts on the two competing with one another?
