Hi, just wanted to share some photos of the cacti I repotted 4 years ago now. They are now 9 years old and the tallest is about 80cm and the fattest about 5cm at the widest. I ended up repotting them, burying the bottom 10cm of original growth. I went slow with the sunlight and water that first summer, then the next year moved them outside and they really took off and started springing out pups for the first time. What a pain to repot, especially having 5 cacti in one pot originally, having to untangle a big mess of roots! I squeezed the big one a little too hard when I was trying to hold it upright in the new pot and you can see the markings. They are just coming out of winter hibernation and the big one is still a bit droopy.

Yeah it's winter right now and I want to repot in April when it starts warming up. The summer averages 28C for a high and the average low in winter is -7C at night. So they only actively grow for 5 months of the year. They don't get any taller from Oct-March/April.
I'd love to plant them outside.... actually this summer I want to bring them outside while it's warm enough which would probably help a lot!

They'll never be planted in my yard here in Rhode Island!

Halcyon is the "soil up to about half way" just straight potting soil?
I thought about cutting and rooting them but they just get so skinny without water.....I don't want to cut them until they outgrow my house!

Thanks for the advice! One of them is actually sending out a root about half way to the top and I wasn't sure what it was at first. The first picture are those same bridgesii when I first repotted them 4 years ago.

I have some 5 year old trichocereus bridgesii that I sadly haven't repotted in 4 years. The tallest ones in the picture are about 53cm. This year will be a good year for them because not only will they get a new large pot (or pots) but they get to leave the 4 year old store-bought cactus soil mix I used at the time! I'm thinking 1 part garden soil, 1 part pearlite (or pumace) and a small amount of sand for the new soil mix.
My question is this: I was thinking about burying them about 10cm deeper than they are now, which would put the thin 1st year of growth under the soil and hopefully make them more stable (see picture with drawn lines and text). Not only is the bottom of the cactus thinner than the top but a few of them are also leaning at the bottom then they curve up to vertical at the top. Is this a bad idea? Will I rot out the bottom? I live in the cold north of the US so they've been grown indoors and have a pretty controlled environment. I'm also hoping by mixing my own soil this time it will be better draining and not rot out the newly buried portion.

Repotting Trichocereus Bridgesii

Because the top half is fat and the bottom skinny? It's first 5 years were grown indoors and it's last 4 outdoors. I'm not sure if it wil ever recover......
