6 years ago I bought a 1 gallon monstera that was labeled as "foliage" at home depot. For the first year it was a house plant, but then while we were doing some construction she got moved to the front yard. By the time the construction was finished about 8 months later she had already started rooting into the ground and seemed happy, so I let her just exist outdoors. Things have now gotten a bit out of control as she's steadily taking over my entire yard. I want to cut her back but am worried about killing her from shock because the stalks have grown so big it is more like taking limbs off a tree than pruning. Any suggestions on how to keep her happy while getting her back at least somewhat under control?
