Hey guys! I was watering my plants when I noticed these things in the stems of my echie blooms. If you look closely there are the black things and then on the actual blooms themselves are things that appear white... what are they and how do I get rid of them? Do they damage the plant and can they spread?

Looks like aphids. Try to spray with a solution of alcohol and dishwashing liquid to remove them. Do it before the sun hits the plants.

If you find ladybugs around..they will love those aphids too! yum! yum!

The white is probably mealy bugs. The alcohol/soap spray will get rid of them too if you're thorough about it.

I would amputate those inflorescences. That is what I do when I see bugs on my Echeveria inflorescences. Quick and easy. I have never found it feasible to try to clean them/decontaminate them. The bugs are quite contagious and will spread if given enough of an opportunity. I'd rather my plants survived to flower another year, if given the choice.

Definitely aphids.
I agree with Baja.
There are too many bugs and the flower spike will never recover
or rather it will never look good so just cut it and throw it into the trash can.
There are probably not any aphids on the plant itself.
They really like the flower stem.
Good idea to spray the plant anyway, but keep out of sun until it drys.

Aphids!! AHHHH.... Grumbling :

I agree with all that stuff that has already been said. Smiling
