I grow and like them. For me they seem to do better (and do very well) in pots and baskets, than in the ground but I am not sure why. They bloom continuously and I have even had one or two seedlings come back (in pots) the following year.

Great! Before and after pictures below. I bought them early April and put them in a larger container and they did great until a week or so ago. The problem is they're not blooming profusely now. They get sun from morning to around 4pm, and we've been having an unusually hot summer.

They've been fertilized twice with a fertilizer for flowers so the plant doesn't put on all green.

I'm wondering if I've been watering them too much, (once a day because of the heat) and if they get too much sun, and if it's time to cut them back to produce more blooms. The plant is already full grown.

What tips can you give me? I also love Bidens, have you tried those?

Part of me thinks I've been over watering because of the tinge of yellow on some of the leaves, but when I check them each day, they're very dry on top of the soil.

In Houston area, I treat them like regular petunias, ie enjoy their exhuberance in spring and replace in summer when heat is too much.

Well, me and petunia's don't get along! I read in mid-summer when the blooms slow down to cut the plant back like you would petunias and other plants to begin the next bloom flush.

It's barely June, so I'm wondering if they're ready to be pruned?

Yes you can cut them back in summer like Petunias. May be ready to be pruned but I am wondering if they are getting enough sunlight where you have them?

They get full sun until about 4pm. Since Bossy said she replaces them in the summer because of the heat, I wonder if our heat is the problem? Very unusual heat we've been getting for over 4 weeks now. Almost a 100 every day. I don't think I'm over watering, but they do get water ever morning because of the heat.

It feels like August here.

Petunias will wilt when it's very hot, so I imagine calibrachoas will as well. You have to deadhead them, too. It's not enough to touch the soil to see if the plant needs watering, you have to stick your finger into the soil an inch or so to see if it's moist. You might try adding some mulch to keep their roots cool and prevent so much water loss. Mine are doing great in NYC, growing like weeds and covered in blossoms. Might well be your extreme heat is cooking yours.

Thank you Esther. Below is another picture I took just now, and I noticed the plant looks like it's dying, not sure though. I watered it this morning and the top is already dry.

I read they don't need deadheaded but do need cut back in summer for new growth, so I'm going to do that today.

The portion of the picture is top center, and I'm wondering if the plant stems got too heavy for it.

This is a fairly large area of the center. When I first saw it I said, "he!!s bells!" lol

Esther, I forgot to mention that the plant's never wilted. I'm also thinking it may need a bit of iron because of the leaf color. How much I have no idea. :)

I bought and planted some for the first time this year. The ones I put in the full sun just couldn’t take it and had to be pulled out and tossed. Below is the best one which gets some direct sun every day. I have others in the ground which are just not doing much. Maybe later in the summer they will get going. They are pretty but not as tough and dependable as some other annuals, the “tried and trues.” I would get another plant next summer but I agree that they seem to do well in pots.

I have them every year in pots (D/FW) .... in morning sun/afternoon shade (but still bright light). Some years, I do cut them back around mid-summer, if they get too leggy. I have noticed that they prefer to dry out a bit between watering — they don’t like constantly wet feet and especially don’t like poor drainage. The first time I had them, I overwatered and they died from the soggy soil. And I think they are pretty sensitive to soil PH, which in turn affects how much iron they absorb. Our heat level is fine; they come from Brazil.

I’d ask at your trusted, local nursery about them in your area/soil/conditions.

Mine this past Spring and today (they’re reaching for more sun, so I may move them to get a bit more):

Miz G, those are so pretty and they match your furniture. :) I cut back on the sun the plant was getting and it's doing okay. I wish they had smaller plants when I bought mine.

Thanks, Oakley! Since I took that pic, they’ve gotten very leggy, so I think I’ll cut mine this week, too.
