Any of your ideas will work just fine with Ae. Fasciata,as it is a forgiving plant. Most growers recommend leaving the pup attached to the mom until it is at least 2/3's the size of the mother plant. At that time you can repot leaving them together to make a nice grouping.Sometimes the mom will produce another pup as well,giving you a triple plant.If you decide to seperate,I find that removing the mom and repoting the offset with roots,thereby reusing the established root system,works very well.If you decide to repot just the pup,best to be sure it has established a decent root system of its own,and then toss the original plant. If you decide on having a grouping,and the mother plants outer leaves begin to brown out,they can be easily removed by cutting the leaf down the center,and pulling the halved leaf to each side.They come off easily that way.Best not to put water in the cup of the mom after blooming,as that can lead to rotting of the main stem. Whatever way you go,I'm sure it will work out well. Bob C.
