I'm hoping some of you semp experts can help me out. I have a 'Silver King' that I planted 2 years ago. Last summer it bloomed, and this spring, it has a bunch of babies. This was a pretty large, semp. The babies are pretty tightly packed and are starting to get a little size to them. What I'm wondering is, should I separate these things at some point to give them more space to be big like the mother plant? Or do I just let them make their own way? Here are pictures of the single and the babies. I've never given a lot of attention to the rest of my semps, and don't really know the best way to separate these if that is indicated. Would love to have the big guy back. Any advice is appreciated.

That is a very pretty semp you have there.

You can separate the babies from the mother plant or you can just leave them. If you leave them, they should root themselves in the ground around the mother plant.

I don't separate mine from the mother until they are well grown. In the next couple of months I will have a lot of babies that will be maturing and leaving the mother plant.

Thanks Melissa. I will wait a bit and then perhaps space them out a little bit to give them some room to grow.

Well said Melissa. I have done both ways.
I can see several generations in that colony. An easy to to see if they are mature enough is to give each a little tug, to see if they are already rooted. If they are you can remove the now, this is the time of year that they grow the fastest and will make the change quickly. In a short while all of the will be sending out new offsets.
I would give the older ones enough space that their new offsets.
Tim does this and all of his colonies are beautiful.

Thanks Lynn. I will try giving them the tug test. I usually just let them do their own thing, but this is such a big semp that I feel like they need to be spread out a bit. I have a couple empty spots that I could move a new bunch to fill in anyway.

I'm not sure what your weather is like this time of year, I can't remember. We used to live in the Wenas Valley between Selah and Ellensburg. The semps should be able to root in again before the really hot dry weather begins.

We've been having an extraordinary amount of rain and a cool spring so far. All that moisture is helping me try to get my rock garden shaped back up - it's so hard to weed when it gets super dry.

Sounds like the perfect weather to get that all accomplished.

Rock garden! Need pictures please.
