Potting together Not a good idea , quite often they have different watering requirements and what happens when their roots are all tangled up and you need to repot them ? Sandy mix Not really a good idea but you can use coarse sand builders sand as an amendment to succulent gritty mix . Water floating on top This could be due to the fine particle size of the potting mix , as long as the water eventually after a few seconds flows down and drains out of the bottom it should be okay . Also peat based mixes become hydrophobic when they dry out , that is one reason they are a very minute quantity if any of succulent mix . <| sep |> he didnt even get rolled back LMAO what a joke , false unrestrict <| sep |> IGN Kenneth Deposit Spearow Gender Male Level 11 Request Solgaleothanks !
