Zone 7b. Our garden center planted 6 limelights last Sept. These two are not doing well. The others are fine a few have some yellow leaves. These two are in part shade while others are in full sun. I used a cheap metal probe tester I had in hand and it said that my soil is alkaline. So I bought the espoma soil acidifier and applied it to the limelights 3 weeks ago. Nothings changed - in fact it looks worse. What’s wrong and do you have any tips?

Thanks

Do these have HVX? I don’t know the varieties. I think the green ones just have sun damage but it’s my first year with them - they came from my sister’s garden - just checking to be sure. But the variegated one has been in that spot for years. Thanks so much
