First off, yay for new succulent babies! It’s so fun to see these grow with little effort on your part. You’re clearly doing a good job caring for it.
I definitely think a new pot would helpful. When succulents get really cramped, usually their growth gets to be a bit distorted. If you can give it a bit more space, those rosettes will come out from the mother plant and look awesome!
As those new babies start to get larger, where they’re the size of a quarter or a little bigger, you can cut them off and plant them into a new pot. For now, though, I would recommend leaving them on the mother plant and letting them grow.
They’ll grow pretty quickly this way, and it will be fun for you to see how big they can get. They will form a really nice clump of succulents.
Now, as far as whether or not you should repot them now, or wait until it gets a little warmer, it’s really up to you! If you listen to Episode 21, I talk all about when to transplant your succulents. If it were me, I would go ahead and replant them right now.
When the warmer months come, they will already have the space to grow. That way, you won’t have to worry about repotting it then. They will still be healthy and perfectly fine if you repot them now.
Once you have them repotted, go ahead and let them grow for a week or two, just as they are. Then, as the temperatures do get warmer, I would definitely recommend fertilizing. The fertilizer will give your succulents the extra boost that they need, and you’ll really start to see their growth take off.
If these are indoors, make sure they’re getting plenty of sunlight so that the growth doesn’t get stretched out.
Fertilizer will help both the mother and the babies grow, and grow faster, so this is best done during the active growing season for your succulent. In the case of this Echeveria, that would be summer, so this would be a good time to fertilize.
If you have a succulent that you’re not sure of when it’s active growing season is, check out this post. I have a list there that shows the active growing seasons for most major succulent types.
If you’re planting in the spring, and you have a summer grower, you’re going to want to make sure you gradually introduce your succulent to the warmer temperatures. If your plant is currently indoors, you’ll want to gradually move it outdoors to the warmer temperatures and brighter sunlight. This will help the growth stay nice and compact.
On the other hand, if you’re planting in the winter and you have a few more months until summer, where it really starts to get warmer, you’ll want to wait to fertilize. Your succulent is going to start growing much more slowly during this time.
A question you may have with regards to repotting this succulent is, how much room do you need to give the succulent, or how much bigger of a pot should you plant it in? You indicated that your succulent is in a 2 1/2″ pot. I would make sure that you’re placing your succulent in a pot that is about 4″. Once these babies take off, they are going to take up a lot of space.
The more room they have, the better shape they’ll be in. They’ll also be less likely to rot, especially if you’re following my planting instructions, and planting them above the rim of your pot.
Now, as these little babies start to get larger, if you do decide you want to cut them off from the mother plant, you can definitely do that. Be sure to use sterilized scissors and cut the babies off right at the main stem of the mother plant. Let them sit out on a dry surface in bright, indirect sunlight, and allow them to callous over for two to three days.
Then you can plant those pups in their own pot, in another arrangement, or in some sort of fun project!
