Do I need to remove the old soil?

Hi, I'm a firm believer in washing off all the old, caked, Peaty mix from the roots of plants,and always do that. I want to uppot my Crassula Gollum. It's been in its pot for 1.5 years. The mix is about 2/3 pumice from GPP, and about 1/3 non Peat cactus mix from Repot me.

I simply want to give it a bigger pot so the roots can have more space and support anbigger plant. Since it's mostly pumice, do I still need to wash off all the old mix, or can I simply place ina bigger pot with more of the same mix?

    If you don't mind my opinion :) - the pot diameter is big enough. But if my plant, I would get one with wider bottom.

    And...I would separate 2 plants, or if it is just one, I would cut it into two! Both branches are very nice, they are full of leaves and I think you would have 2 very nice trees. This way it is just very wide and (maybe?) flat - growing more sideways then all around - but I am looking only at the photo and it could be misleading. I would like to see trunks fattening at the soil line, and tapering - gives plant that 'old age' look :)

    Your potting mix, if well draining, may just crumble away well enough that you don't need to get anything off the roots.

    When I repot a plant like to a larger pot I do not generally wash off the old soil. I usually lightly remove from soil around the perimeter and bottom of the root ball (brushing it and roughening it up with my fingers), and some of the media from the surface (say top 1 centimeter or so, I figure most of the salt build up will be there). This leaves most of the roots intact, and it should hardly miss a beat after repotting.

    I do pretty much the same thing as wood native, if I am repotting a plant that was potted in any mix that included C/S soil, regardless of the percentages and what the other components were. The only time I really bare-root the plant meticulously is if I'm going from a soil-based mix to pure non-soil gritty mix (some combo of pumice, grit, Turface etc). Then I even wash to roots clean to prepare for a new inorganic mix. BTW, Manuel, those are GORGEOUS Crassula. All I can say is -- WOW!

    When switching to a majority pumice mix, you should get rid of ALL the old soil. That will let you take full advantage of your new more expensive mix. Wash it all off under the hose - this is a very nice sized Gollum so any broken roots will come back quickly.

    Thanks everyone. First I would like to post a couple more pictures so you can see the two trunks and the canopy. Then I'm going to follow up on the comments.

    Some of you have walked me through my struggles over the past couple of years. This is one of the plants that survived the incident on the roof, when the drunk twentysomethings destroyed several of my plants. This one was only knocked out of it's pot, and lost two branches. I quickly repotted it into a slightly bigger pot, and nursed it back. It's been back on the roof since spring, (Fingers crossed) where it gets sun from morning to nighttime. I only bring it in when I know it's going to rain. I water it whenever I want. Sometimes I skip two weeks. Sometimes I water it 3 times in one week. I think the mix is gritty enough that I can get away with this. It's grown by leaps and bounds. I originally bought it 3 years ago from kmart, as a tiny start, for $3.98

    Rina: As always you have eagle eyes. It is, indeed, two plants in there. I'm very short of space, so I figured I would keep them together and let them do their thing.. If we agree that the pot is big enough for now, I could wait until next year. The pot IS too narrow at the base, so to keep it from falling, I place it inside a shallow, wide, "azalea" pot.

    Woodnative, Robinswfl, and EwwMayo: This mix is about 2/3 to 3/4 Pumice. Water runs right through it. The reason I don't want to switch it to pure pumice is that I want something to help hold it together in case of any other accidents. I forget what the soil constituent is, but it was rather pricey from RepotMe. I've been switching my desert cacti to pure Pumice, but for a few others I want something to help keep it together. That's why I was wondering if I could mix an additional batch of maybe 3/4 Pumice and 1/4 soil and fill in around it in a new pot.

    I apologize for all my rambling.

    By the way, I fertilize with FoliagePro at 1/4th teaspoon per gallon of water at almost every watering. In the winter I drop down to 1/8th of a teaspoon, but then my watering is more infrequent.

    I remember this plant and your post about those hooligans. Glad it survived and is doing well!

    Didn't want to suggest anything different with your mix - I meant that when changing from soil to any gritty mix all the old soil should be removed. =)

    I certainly like some soil in the any grit/pumice, especially for jades. I do not like the pure gritty mixes as much as I like having some organic soil in the mix, though I know the pure gritty mixes work fine for others. I only have one or two cactus, most of my other succulents like Sansevieria trifasciata and the jades seem to appreciate a little more moisture in the soil, at least when actively growing, even though they are succulents

    Agree with woodnative on this, especially for jades. My jades potted in all gritty have done pretty well, but my jades that have about 1/4 to 1/3 soil have done splendidly. I do have some aloes in pure pumice that are thriving along with some haworthia -- but more and more, strangely, I am finding that many of my plants like a little soil. Either way, Manuel, you will do what's right for the plant. I'm glad these jades were saved from the rooftop disaster. I remember it too, and am glad you have had such success afterwards.
