Late summer prune?

[Tortuga]

I’m in zone 8b. I have a few plants that could use some tipping and slight shaping. Is it too late in the season to be doing this? I’m concerned about leaf miners now and the new growth not hardening up in time before (whispers) winter. Any advice is appreciated

For me in Australia it's Spring (We've already hit 30C) and the weather is great.
For you in the states, today starts Autumn, and I'm not sure about you local conditions, but I reckon you would get your first frost in approx. a month and a half, but I could be a bit off. I wouldn't do tipping of trees yet, I would wait until Spring (Or when you are certain that the last frost has passed).
Cheers.

Thanks for the input. Generally my first frost hits around the 3rd week of November/first week of December. So there’s atleast 10 weeks before frost arrives.

I don't know if the growth will harden well enough in that time. I reckon they'll still be tender by the time frosts hit.

Isn't the fall equinox on Sept 22 this year?

Yes (I googled it), but what does that mean for when frosts hit?

"For you in the states, today starts Autumn" just thought you were off by a few weeks that's all.
