Just curious, since this will be my second winter of enjoying semps, lots of dead leaf removal before winter is common? I figured it was more common in the spring. Or is it both?

It's not common for all semps all at the same time. Coincidently both years I documented leaf removal in Oct of 2020 and 2021. Timing might be spread over couple of months and other weather and moisture conditions may lead to less or more dead leaves. I also find that different cultivars can have more dead leaves than other cultivar given similar soil, similar sun exposure, and same location.

If you zoom into this photo taken in Oct 2020, you will notice all the pots vary in amount of dead leaves present

This pot didn't have much leaves in it to pull off
Thumb of 2021-10-24/webesemps/f15c80

This cultivar had much more dead leaves removed

Nelli, if fall clean up is done on the semps, they shouldn't need any removal in the spring. Unless it is a cultivar that tends to rot in the winter/spring.

Bev, @webesemps I am as ready as I will be for winter, I think.

Am enjoying seeing all your semps, you really have expanded your varieties. That's a lot of tweezing you are doing. Such patience.

Marilyn, it's good attention for my potted semps as I am unable to provide them with more planting space and sun exposure. I do collect rainwater to water them so hoping they are happier. Patience is easy to give them.

Bev & Lynn, thanks for the info. I'll try to research my varieties and see if they are known to rot as well as keep an eye on them all. I know a couple are known to rot, either from reading somewhere or by experience, but I've greatly increased the amount of varieties this spring/summer so I will have several for a first winter. Crossing Fingers!

Keep us posted on how they do over winter and spring. It is helpful to all of us to know which ones do best in the different growing locations/growing conditions. Thumbs up
