Leaves On The Underneath Have Started Turning Yellow All Of A Sudden

Question

I purchased this plant about 3 years ago and haven\’t had any issues until the last couple weeks. All of a sudden, the leaves on the underneath have started turning yellow. Since it\’s getting warmer out, I moved it to a slightly shadier spot in hopes that will help. Unfortunately, I don\’t remember what it\’s called. All I remember is that it had the word lemon in it. I\’m unable to troubleshoot the issue since I don\’t remember the name of the plant. If you could tell just by the picture what it is that would be a huge help. I picked a lot of the yellowing leaves off so it doesn\’t look as bad in the picture as it did

That looks like Viburnum tinus or similar glossy leaved Viburnum. Unfortunately, there are a few things that cause this. Fortunately, you can test for some of them. Repotting will rule out root compaction and low fertilizer. Just keep an eye on pH. Overwatering or underwatering can cause this, as well. Here are some articles that will help:
