Does anyone know the composition of that powder that comes in packets
with cut flowers (e.g., roses) that you add to the water so the flowers will
keep longer?
I am an entomologist and when I rear larvae I need to keep them on their host
plants; and I need the host plants to stay fresh as long as possible. Usually I
take cuttings from the field of the host plants. I thought perhaps I could make
up something comparable to this "Stay Fresh" to help me.
