Nothing to it ,right? I mean they thrive on neglect.
Last year I purchased quite a few of these in mid Summer in hopes to actually try hybridization this year.
These are great harbingers of Spring.February is the time,possibly,these start to move a little.

As for protection from cold....not needed for most.All I do is protect with very loose plastic around 3/4 of the table in Winter to protect from rain.Also they do well in Summer under a piece of clear polycarbonate on my grow table.I just leave them under it year round in full sun,as some will scorch a bit in mid Summer.Water after bone dry only in growing season.Keep bone dry in cold months.I like to add a soluable fertilizer at least a few times at beginning of growing season.NEVER IF FROST IS PREDICTED!!They react dramatically to fertilizer,so only a few times or they will turn to green lettuce and flower and die after flowering.I use 50/50 good potting soil and grade#4 perlite.Need excellent drainage,so at least 50% chunkey aggregate.Also a very thin superficial drainage layer on top ,so there is less humidity around rosettes.
Mid Summer is best time to separate in their slight dormant state,and order them too.Else they may bloom instantly from disturbance at any other time.
Also,I am told they do not like chlorine.
These are great!
Here are random pictures from last year and their Winter location on the grow table.

Those are so cool! I’m super jealous! I’ve never seen succulents like that before, but I’ve never owned one honestly haha. I’ve thought about growing some but I think my next endeavor will be nepenthes instead.

“Nepenthes”
Something tells me they do not enjoy Miracle Grow.

Awesome!
I just wish I could leave bonsai on the growtable all Winter long and bone dry only to start growing again with application of water in Spring:cool:
Then everybody would grow bonsai!

Spring!
These Sempervivum never cease to amaze me.I literally just pulled the winter plastic off the grow table and watered them with Miracle Gro on Tuesday.Now three days later they are back to life.They go the whole Winter without any water on the table.
Here are some before and after .......three days apart!!!

When you wake them up like this with fertilizer,they absolutely cannot freeze from this point on during the Spring.I only fertilize them a few times after this.
The coolest part is when they send out all the chicks now and get full and some mound up too.

Are these the only succulents that can go whole winter without water? Pretty interesting!

I don’t know really.As far as succulents go,I have only grown these.
Some did not hold up to my abuse,out of 24,I lost three this winter.But it makes for good selection of cultivars that I may wish to hybridize:D

I have a book that will be available in May that goes in depth with hybridizing these Semps!

These so remind me of my grandma, my best friend. She had pots full of these. Happy memory.
That is great! I got nothin’ but happy memories with growing these too.I think it will be fun to try and hybridize maybe a couple my favorite specimens and see what the seeds grow.That is if the right ones flower together.
