Novice gardener,about to transplant iris and calla lilies. Any recommendations? I’ll add some organic planting soil and bonemeal

Question

to the new site which gets plenty of morning through mid day sun. I’m in Z8, coastal Carolina.

Answer 1

I wouldn’t add anything unless your soil test says that you need it. At least for Irises. They don’t really like for their soil to be overly nutrient rich.

As for the Calla Lily- They will want some extra nutrients, but this is best to be a balanced nutrient rather than just a part of the nutrients.

Make sure that you supplement nitrogen and potassium, as bonemeal has high amounts of phosphorus but very little nitrogen and potassium.

Answer 2

I’ve grown calla lilies in the ground for many years. It likes/requires moisture. If your coastal Carolina yard has sandy soil, dig 3-4 inches of sphagnum peat moss into the soil before planting.
