Why do Portulaca flowers close up during the middle of the day and not reopen till the next day? They have full sun most all day and don't draw many butterflies but thoudands of bees love them. Thank you.
This is the growing and blooming pattern for these flowers.

The portulaca have been blooming beautifully but now there are many spent blooms. Can it be cut back for new growth? Today is September 7. We live in Pennsylvania. Usually no frost until near November.
Certainly trim off the dead flowers, deadhead.
This should encourage more blooms until the weather cools.
Trimming the plants back to far will likely not hurt but the temperatures and sunlight conditions will not be enough to bring on a big flower display.

How to care for potted portulaca during winter months?
Your Portulaca are usually grown as annuals so you can discard the plants at the end of this growing season.
They are very easy to start from seeds each year.
If you have Portulaca planted in the ground they will reseed quite easily.

Petunias in the pots are doing extremely good and are expected to maintain a good display for one more month or so till I replace them with Portulaca. But I think it would be too late by then to transplant Portulaca seedlings. Can I transplant Portulaca seedlings in between Petunias in the pots? Will they survive/thrive? Or some other suggestion please.
Thanks. Moss rose is going to be planted in new pots now:) Out of curiosity, my question stays, can moss rose seedlings be planted in between mature petunia plants and yet thrive?
Why are you replacing your Petunia so early in the season? They should grow and continue to bloom throughout the summer.
Deadheading the spent flowers will help keep them blooming.
Here is a link with more information on the care of Petunias.
Perhaps you can pot up the Moss Rose into another pot, this allows you to enjoy both flowers without disturbing the pot with Petunias.

Do portulaca plants flower more when kept short?
You can dead head the spent flowers to encourage longer blooming period.
If the plants get leggy, you can cut them back mid-summer.

We live in Southern California - dry! Been planting succulents, but I understand this flower grows well in the sun and low water needed. My question is: I have dogs, not they usually eat plants or flowers, but are they a plant/pet safe? Do they only come in a ground cover type plant or are there some that are more bushy? Thanks, will be looking forward to your response. Also, can you suggest other low (not ground cover) plants?
Portulaca is a ground cover plant, there isn't a variety that will bush up. They aren't poisonous to animals.

My portulacas have the unopened buds snipped off before they have a chance to flower. What creature does that?
My research shows that Portulaca are favorites of rodents, mice and such.
