I have some mulch beds made up of heavy clay soil here in southern Ohio (Zone 5). I recently planted flowers without using topsoil, and now I'm worried. Are they all doomed? Should I go ahead and pull them out to replant them with topsoil around them?

Honestly, I've got clay soil too, and my local nurseries said that for shrubs, they don’t recommend amending the soil anymore. It’s interesting because I’ve had success with flowers too without any amendments. If you prepare the hole well enough, that usually does the trick!
First off, don’t panic! It really depends on the types of flowers you planted. Some flowers can thrive in clay soil, especially certain acid-loving ones. Clay soil is actually nutrient-dense, but it can make it tough for plants to access those nutrients. If you've loosened the soil a bit, your flowers might be just fine, even if they don’t grow as big since they’ll spend more energy on root development. Just keep an eye on them!
Yeah, I agree! Just make sure they're getting enough water, and they should be okay.
In my experience, it’s usually not a big deal. I dig a larger hole, care to mix in some organic compost, and sometimes even just backfill with the existing soil. Prepping the soil definitely helps, but I've seen plants adapt to not-so-great soils too. Just make sure to water them well while they establish!

That’s good to know! I might try planting without amending next time.
