Succulents that put out aerial roots typically do so in search of water, so that—combined with the browning leaves—suggests that your plant is in need of more water. However, if your plant doesn’t get much light this time of year, you do need to be careful not to overwater. What’s your watering schedule currently like? During winter months, water the plant deeply but don’t water again until the soil is almost entirely dry. Once you get the plant back in stronger light, you can increase waterings—still being sure not to water again until the top inch or so of soil is dry.
As for what to do with the aerial roots: You don’t want the plant to be planted deeper than about halfway up its base, so if the soil was already at that level before you added more, it would be better to remove the extra soil and simply snip off the aerial roots with clean scissors. If you do this, don’t water the plant until it looks like its wounds have healed; this will help to prevent fungal disease.
