what did you plant them in.. what type of media ... and what fert might you have added ... whats the weather been since planting .... where are you??

without a pic.. its hard to make any guesses ... with the few facts you provided ...

imo.. patience is the only remedy ...

I planted them in miracle grow potting mix with fertilizer and haven't added any other fertilizer. I'm in NE KS and it's been hot (90's) until yesterday when it rained and cooled down a bit. I try to upload a pic shortly.

Those look like seed pods forming. Pinch those off. It looks like the plants are between "waves" of flowers.....at least to me.

Annuals try to set seeds, but that hinders the next wave of flowers/buds. Pinching those old flowers off AND the forming seed pods will allow the plant to focus on regrowing and reblooming.

Petunias foliage and stems have a sticky residue so you might find your fingers will get tacky pinching the plants. ;-)

Hope this helps,

Chris

boy.. a pic is worth a million words ...

next time.. buy a younger plant ... this one peaked before you got it... thats why it has all those seed pods ... sterile or not is not the issue ...

and then you stressed it with the repotting ... live and learn ...

its a nice green.. so its getting over the repotting.. so 2 thumbs up there ...now you have to do something about the rest ..

the link has some videos.. that i did NOT watch ... and i think this is your next step ... you could spend hours cutting off individual seed pods ... but i am sure it can be done much faster ...

think of it this way ... a plant has one goal in its life.. procreation ... once it has set a lot of seed pods ... its job is technically done... and it slows down flowering.. if not stops altogether ... so we prolong the flower show ... by continuously removing the seed.. to keep it flowering ... its called deadheading .. or pruning ... and of course.. the repotting doubled down on slowing it down ...

Are those Proven Winners Violet Star Charm? Sorry, I googled, but couldn't find just a Violet charm. If they are, they shouldn't need deadheading, and shouldn't be forming seed pods.

I see the picture, those are definitely seed pods... I'm just wondering if your greenhouse made a mistake (or someone switched the tag). Did the plant come in the white PW trademark cup?

I have several of their supertunias, none of mine need deadheading, they just keep blooming their fool heads off.

But yeah, I'd trim all of those off. It should recover and fill in and bloom in a couple of weeks. Good luck!

Weird. Even their website says you don't need to deadhead that one. Clearly, not true.

In any case, they should be fine

I just wish they'd BLOOM! I think I had them 2 days before they stopped and they've been on hold for about 3 weeks now.

Mine are taking over their pot!

I WISH!!!!

Pinch them back. Pop off the seed pods and toss em. They may reseed for you (mine do routinely). Petunias are generally hardy, but they can wilt easily in hot weather. They are also heavy feeders. The Miracle Grow in the planting mix may be fine for now, but later in the summer you may want to use a liquid feed.

Actually plant asked about looks pale green (as though needing to be fertilized) and somewhat droopy to me, notice for instance how deep green the other planting shown here (with flowers) is. It also appears your flowerless plant is growing in the ground, if so the potting soil you added at planting may be producing problems - such as causing it to be on the dry side much of the time. This often happens with amended planting holes, due to the amending creating a marked textural difference between the amended soil in the planting hole and the soil around the planting hole.

Try asking at an independent garden center, they no doubt will have something they are pushing for use on flowering annuals.

I'd never fertilize with anything having a 58 number for phosphorus, that has to be huge overkill. Once you overload your soil with phosphorus you have to replace the soil to get rid of it, as P hardly leaches at all.

The local garden center was who told me about the 58 phosphorus fertilizer!

Yes, it's a "bloom+" type to increase flowering, and I did (by accident) use a slightly weak mixture. And yes, the plant is in pot. So maybe I should apply another weakened mix??

I don't know what the label recommends, but I'd personally fertilize every two weeks with that fertilizer.

When I fertilize container plants I water the pot with just PLAIN water until I see water running from the bottom, then I water again with water soluble fertilizer. That way there is no chance of fertilizer burn.

Thanks, Chris. I'm not looking at it right now, but I do think it said every 2 weeks. And I've always wondered about watering before fertilizing. Good to know.
