Question
I have a plant which was given to me and the person said it was a Pencil Plant.  It has grown very beautifully, but it needs to be cut back and I would like to grow more from the cuttings. Where do I cut this particular plant without ruining it. Please help.

Pencil plant is a common name for more than one type of plant...Sky pencil is a boxwood exterior landscape plant...A few succulent plants are also called pencil plants...Without a picture I can only guess what yours is...A few plants called pencil plants are in the rhipsalis family of cactus...Others are in the euphorbia genus of succulents...I think yours is euphorbia tirucalli...Type it into your search engine and check it out...
You should check out propagating succulents on the Internet also...Make cuttings just above where a branch is located...Take the cutting and place it into a good cactus potting mix...plant it shallow into the soil...Then treat it like a normal succulent plant...
Succulents usually die from too frequent watering (or letting stay dry too long). In this case pencil plants can die easily if kept too wet and not allowed to dry enough between waterings...You want to make sure they go dry between waterings...They do rot out easily if kept too wet...Water your plant based on how much it weighs when thoroughly watered VS when they are ready to be watered again...Pick the pot up and feel how heavy it is after watering it...Don't water it again until it feels considerably lighter and the top of the soil is light in color. Do water in the early AM on sunny days...Be especially careful when watering succulent plants during the shorter day-lite hours of winter...Err on the dry side side with these plants...Do keep them warm and avoid cold drafts...
Direct morning sunlight (especially up till Noon) is good for most plants. Cacti love light...A lot of succulents will not tolerate direct sun all day...They just need a bright location...

Hope this helps...Let me know what you think...
