You will probably get a response if you describe the issues and include pictures in your post. People are reluctant to follow links or to spend time to watch videos.

Thanks for the response. I figured a picture (or an 11 second video) would be worth a thousand words.

It's literally a video comparison of two Royal Candles purchased on the same day from the same nursery, but different trays.

One's doing OK but the other's not.

One looks blue & vibrant, while the other looks burnt out almost. Watering is done every two to three days, depending on the weather of course.

I'm just trying to figure out how to save the one plant.

I'd move it, flush it and deadhead it. Is it possible that your "pinch" (presumably in water) of Miracle Grow was heavy-handed? I don't think the damage occurred in the nursery. It's either despising the pocket of soil it's in or it's been burned by something, which I would guess was Miracle Grow.

What's your strategy for weed suppression? That's going to also have to get addressed, but that's not the problem here.

Floral's right. We get sent to bogus links, so people hesitate to follow one. I did, but I was sure I was getting punked.

Did you get the video to work? It didn't for me.

Yes, I did. I'll check it again.

Yes, it still worked for me.

"Deadhead" it. I have yet to try this.

I will try this & post the results.

Well, the video still doesn’t work for me. I only see the still at the start. But that shows a plant that definitely does need deadheading. As a rule deadheading is good practice for any perennial.

This probably won't work for you either, floral, but you can try.

Yes. That worked.

I just realized that I failed to mention one thing : Because they were low on inventory (they were down to their last two Royal Candles) I bought both of their last trays.

One was looking good, while the other looked exactly as what you see in the video.

I figured I'd take a chance. They were on sale. LOL.

So, it's not that the plant was doing OK originally & then began to wilt. I bought it like that *hoping* I could revive it.

I just popped off three of the heads (deadheading). I just took off the flower part. It was my first time doing this, so I hope I did it correctly. 🙏

@annpat The amount of Miracle-Gro that I used was literally a pinch. No more than a quarter teaspoon (if that) to our 3 gallons watering can.

I probably watered half a gallon to this one plant. It's definitely not the Miracle-Gro that caused this wilting. I bought it on sale exactly like this, in the hopes that I could revive it. They were all out of Royal Candles and I really like how it looks.

When they're healthy. 😂

P.S. : So glad that I didn't contribute to the negative stereotype of punking the other users on Houzz. I'm new to gardening. Loving it to. The learning curve is something else though. LOL. Next stop....Paw Paw Trees.

Deadheading with small scizzors is easier than trying to pinch. With those veronica, you can follow the flower stem right down to the plant to deadhead. You don't want to leave a bunch of unsightly, flowerless sticks sticking up from the plant.

I'm not sure there's anything much wrong with the plant. It could just be past blooming. Usually the last two plants weren't the two best looking plants in the flat. They're the leftovers. And, sometimes, a plant just doesn't want to be where it is. If it doesn't spruce up, you can move it over a foot. (I understand that they were that way when you bought them.)

You are going to have to address the weeds before long. Plants don't like competition, and usually it's the thugs who win out. There are lots of different ways to address the weed problem.
