Great idea on the powdered milk!
I have 4, #32 cans of the stuff leftover from my Dad’s ‘prepper stash’ that I ‘inherited’ when I moved him from his apartment. I’ll use up some of it for soups & baking; we don’t like powdered milk unless we’ll HAVE to drink it in the future. (I will save 2 cans for the two of us; it makes a TON of milk.)
As you know, when I have an empty milk jug, I fill it with water and feed that to houseplants. My Geraniums and Christmas Cactus are in full bloom right now and loving life. :)
My red and my pink Christmas cacti had a nice flush of blooms a few weeks ago. There were a lot of small budding flowers too, but now they are all drying up and falling off. Was there a way to encourage a second flush of blooms that I don’t know about? Most of the buds are now gone.
