So this cactus is in the front bed at a house Ive rented for the past year and half. Last July 4th it bloomed a white flower. Its pretty stressed this year. So my wife and i decided that we're going to rescue it from this property. We rent from one of the large corporations that does not have employees physically in our area and the company just sold the property to another company so its not like anyone will even know, or care. Can someone confirm if this is in fact a dragon fruit cactus? Advice on how far to dig around the base to avoid root damage.

I got this plant about a month ago from a local nursery. Should I remove this pitcher that is damaged midway? Let the plant put the energy elsewhere?

1.6 pounds and loaded with lead. Leather braided handle for extra grip.
