Should I let my plug plants flower?

Several of my potted on plug plants are flowering or about to flower. They're still a bit small to put in containers outside and I don't trust the weather yet.
Do I need to nip off the flowers? The actual plants don't need pinching out.
Nemesia, calabrachoa (sp), Biden's . Verbena look ready to pop too.

 

If they were mine, I would. You want the plants to put all their energy into growing larger before they flower.

 

I don't grow any of those, but I'd take the flowers off. It'll be a while before they'll be big enough to go out.

 

Thanks @Punkdoc @fairygirl . Cruel to be kind is hard sometimes

 

It's different with small, tough plants that have been growing on in your own site from the previous year. They're easier to establish because they're well acclimatised. Plug plants at this time of year are usually quite cossetted, and need a bit of time.
No point in risking anything, and allowing them to flower just uses up the energy they need for producing a good root system.

 

Hi all, I am ordering some plug plants that I plan to grow on in a frost free room with lots of light. Any tips? First time trying this but I was shocked at the increase in plant prices locally and I do use a lot of annual plants in pots and baskets so any advice gratefully received.

 

My first tip would be to make sure you have compost and pots all ready to pot them on .
I use 9cm pots.
What sort of plants have you ordered?

 

I had plug plants delivered at the end of march, I potted them into 9cm pots, they are now wanting to flower so I'll pinch off the flowers and re pot into a slightly larger pot, i hope I have enough as I ordered extras as my neighbour wanted some.

 

I have ordered stocks, petunias annual salvias,nemesia and lobelia. They seemed like a good price but obviously they won’t be if I don’t take good care of them. I have compost, just a good mpc and lots of little pots

 

I think they will be fine Debs, as long as they have good light and some tlc .
You're probably using peat free compost, and may well already know this, but just keep an eye on the watering. They can look dry as a bone on the top but are sopping wet below. I would always water from the bottom if you can.
As soon as the roots start showing through the bottom of the pots, then that's the time to think about hardening them off and acclimatising them to the great outdoors.
Hopefully by then it will have stopped raining !

 

I have some compost with reduced peat but will take care with watering thanks @AnniD

 

It'll also depend on the size of the plugs - some are tiny, so just check that what you pot them into is a suitable size. It can be a mistake to over pot if they're really small.
If you have any spent compost from last year's annuals, that can be ideal for small plants.
