Help! Repotting a cactus

    Hi All.

    Just spending my Sunday afternoon avoiding work and repotting my cactus. My knowledge of things horticultural is small, to say the least, but I do know it needs repotting as the roots are sticking through the bottom of the pot. However, when looking online for advice, it all seems to say "repot to the same level of soil" or similar. What does this mean? Does it mean my cactus needs to be level with the top of the new pot, as it was with the old, or does it mean to pot it lower down in the pot with less soil, so if its old and new pots were placed side by side, the top of the cactus would be at the same height regardless of whichever pot it's in?

    Please help! Am confused. :confused:

    Put soil into a larger pot, place cactus on top of said soil and pack extra soil round cactus so that the soil reaches the top of the pot.

    Same soil level, but I wouldn't fill it to the top, leave at least a cm of space to water it.

    If you look at your plant carefully you'll see a soil line - usually a darker mark that shows how deeply it was planted last time.
    When you repot, make sure the soil doesn't cover that line or it may rot. Make sure too that the soil line doesn't stand above the level of the soil or the roots may dry out.
    It takes a bit of juggling to get it right but by adding or subtracting the potting material you'll get there. It's not hard.

    If you water your plant from above you need to leave a gap between soil and the rim of the pot or you'll find you're watering the compost out.

    Better explanation than mine, but agree!

    Okay, thank you, everyone!
    @cosmosinfrance - what you say makes sense.
    Have repotted him now. I'm hoping he flowers this year; normally I kill things off pretty easily but my partner got me this cactus specifically with the idea of it being able to live in our warm flat well, so I have been very careful about taking care of him properly.

    What new compost have you used? It needs to be open. Potash will encourage flowering!

    I love cacti and succulents. I was devastated (ok, slight exaggeration) when my huge Aloe Vera died. I'd over-watered it and the roots rotted. :-(

    Do you mean the bag the compost is in?

    Sounds like a prickly situation ...

    No the compost itself - usually achieved by adding extra sand / grit!

    Our Christmas cactus has buds!

    Having said that, they'll probably drop off.

    It's a special cactus compost from B&Q. I'm hoping it's "open" enough - I'd love for my little cactus to flower!

    Saw this thread in passing. Intrigued.

    Thought it was a strange turn of events which saw you REPORTING A CACTUS. I know they can hurt you but it's not really a criminal offence. Yet.
