Michele, now I'm joking what gives you the impression that it is rootbound.
This is what I want you to do, take it out of the pot, just slide it out. Take a mallet and pound all around the side of the pot, then ease it out. Now this is going to sound just awful, when it come out slam the root ball down on a hard table, cement steps, the root ball should fall apart at this time, and I will lay a bet that there could be multible plants, they should fall apart at this time, then gently, loosen up the roots, get rid of the old soil, You must give it a fast draining soil, with no PEAT MOSS , these grow on rocky hill sides in Africa they get their moisture from the foggy air. and what little else may fall during their winter which is right now. Make sure the root ball is large enough to support the top growth. If it is not then trim off some of the top growth. Wait a week then water. The reason for this is that some of the tiny roots could have been damaged when transplanting, and they will rot and will be no good to the plant, and could cause diseases to start. Thats one healthy plant and you should have no problems with it.
Another option, leave the rootball intack. But be sure to loosen up the outside of the root mass, even if you have to cut off the roots that are going around and around. Even trim off the bottom of the root ball 1/2 inch. Then with new clean soil, just put the plant in the pot which it came. They like to be crowded. Remember not to use a pot that curves in at the top. These are suggestions use your own discretion. Norma

Thank you so much Norma! I was able to get it out of the pot without too much trouble but that rootball was solid and wet after I tried to wash off the soil. I did whack the rootball a few times with a rubber mallet and that helped to loosen it a bit.

It has 5 thick trunks in the rootball and a few tiny starters plants but I decided to leave it in one pot since I love the fullness of it. I didn't even break a branch off!

I used 1/2 (bagged) top soil with no peat and 1/2 pumice stones with some perlite thrown in and a bit of volcanic rock. It's very heavy! It'll spend a week inside and then I'll water it and gradually move it back into full sun. I live in Southeast Orange Co, CA so sometimes we have the coastal air and other times the inland heat. We're in the foothills of the Saddleback mnts, only 85 deg in the shade right now.

If you think it needs to be OUTSIDE in the shade I'll have my son help me carry it to the front porch. Too heavy for me to do, LOL!

I now have sunset, gollum/hobbit (can't decide), variegated and a ton of little pots of starters in addition to my 4 regular jades!

Perhaps this will help:

**Crassula 'Gollum**

'Crassula ovata 'Gollum' has tubular (round) shaped leaves with curved, suction-cup shaped tips. Red tips on leaves in ideal light. Pink flowers as in the photo.

Crassula 'Gollum' makes a great potted plant but also grows beautifully in the ground in zones 9B and higher. Some people refer to this as "E..T. Fingers" because of the suction cup tips on the leaves.

**Crassula ovata 'Hobbit'**

Do not confuse Crassula 'Hobbit' with either Crassula 'Gollum' or Crassula portulacea (the "Jade" plant). It is definitely different. Crassula 'Gollum' has tubular leaves with "suction cup" looking leaves while the "Jade" plant has fleshy but flatter leaves. By contrast, the leaves of Crassula ovata 'Hobbit' are curved backwards/downwards from the sides.

It can and will split that pot, get the black heave professional black pots and double up on that one, clay pots would be okay for this species. there are small redwood rolling carts that perhaps would be good for underneath, so you can just roll it along, no lifting.
That is a mature plant and I think it has been pruned several times to keep that shape and thicken up the roots stock. Norma
