Pest, poor soil, too much sun or all of the above? #880318

Hi there,
I planted this plant (frankly I'm not 100% sure what it is) this spring. When it got hot this summer I noticed leaves with red spots. I cut some of the damaged leaves off and gave it some fertilizer. But now I see these black spots and what look like bite marks. I don't see any visible bugs on the plant during the day. I'm not sure what's going on and what I need to do. Plus it's in a place with full sun.

Hi Jennifer,
thank you for using Ask Extension.
if you purchased the plant this year can you find the tag? there is important information as to the conditions for the plant to thrive.
When you first plant something, it's important to ensure it gets adequate water throughout the first and sometimes second growing season. It takes that long for plants to fully establish after transplanting into your garden. The brown edges indicate some sun scorch.
The leaves are also indicating some issues. Yellowing leaves with green veins can be an indication of iron or manganese deficiencies.
I don't think the plant is a lost cause. I would make sure that you water it weekly but make sure the water is seeping in. a single deep watering will promote the roots to find the water. frequent shallow watering promotes shallow roots that will make the plant more sensitive to hot weather. I have a five gallon bucket with a few small holes drilled in the bottom. You can fill the bucket and then the water seeps out (essentially like a drip system.)
