Hey all,
This question may look familiar to those who frequent the semp forum, I asked a similar question over there. Sticking tongue out

Just wondering, is 25-30 degrees at night too cold for young, undeveloped sedums with small root systems?
I will be in-ground planting Sedum Spurium 'Fuldaglut' (Dragon's Blood or Fireglow), Sedum Kamtschaticum (Improved Golden), and Sedum Reflexum Blue Spruce. They are all in 2"x2" pots and cold hardy, I'm just ultra paranoid about killing them due to their small size and lack of development.

If 25-30 is too cold, what temp should I wait for?
Also, would a frost or freeze seriously harm them?

Thanks for any help,
J.C.

J.C. they should be fine to plant now. Just give them a little protection at night. Maybe a cloth thrown over them at night.
Those are all sedum that are pretty tough. What are you planting them in?

Thanks a ton for the info Lynn.

When you ask what, do you mean what medium? They will be in ground (in a raised bed) in a soil, coarse sand, perlite, light gravel mix. Basically similar to what I use for semps, just lighter on gravel. Will that be okay?

Thank sounds great. Most sedum do like some compost or other organic matter, so if they look like they are doing well just add some compost to the mix. They also seems to like a little more water than the semps. If you have grown them before with success just keep doing what works for you.

Thanks yet again Lynn. nodding

No, this will be my first time really growing a bunch of sedums at once.

For the soil mixture portion of the potting mix, I was going to go 50/50 native soil and cactus (succulent) mix.
Should I go 33/33/33 with native soil/cactus mix/ and premixed garden soil (retains more moisture and has higher compost content)?
Or should I just increase the overall soil content in the mix (less sand, perlite, etc)?

I'm know I'm overthinking it, but just curious on general guidelines. I've done a lot of research online, but there are so many contrasting ideas it's hard to know what to trust.

What type of native soil do you have?
I haven't had much luck using the [u][b]Garden Soil[b][u]. Cactus mix tends to be more expensive and doesn't seem to make sedum all that happy. A lot of it will depend on what your native soil is like. That is why there are so many ways to go.

The soil is a silt loam with very little sand or clay. The permeability is an average of approximately .9 inches per hour.

Sounds like your original plan might work.
Even the Garden Soil should work for you with silty loam.
