Transitioning out of summer

[BryceQuinlanTheFirst]

Hello,

I'm new to gardening, this year in spring I planted a lot of pots on my very very sunny balcony, most are for warm weather. I've got huge planters on the railings and several herb, flower and tomato plants. I've been amazed at how they thrived and it's given me such pleasure looking after them.

Can someone please help me understand how I transition them for autumn and winter, do I plant new things? Do i leave them? Sorry if this sounds silly but I'm very new!

Watching with interest! I’m still getting courgettes & some of my tomatoes are still green. Are supposed to dig stuff up for the autumn? I’ve no idea…

Don't be in such a hurry!
There is usually a flush of flowers in late spring / early summer, a bit of a hiatus and then another spurt in autumn - lots of daisy-like things such as asters, chrysanthemum, coneflower, etc.
If vegetables are still fruiting then let them carry on. You will know when they are past it. (That's when you make green tomato chutney!)
A lot of winter interest can come from evergreen perennials that form the 'skeleton' or framework of your garden all year round.

Garden according to conditions (is there heat, light, water, etc) not the calendar.

Good advice thank you! Yes you're right I'm in London and we are usually really warm through Sept and mild into October.

Is there anything nice to plant for autumn, the ones you mentioned?
