Is it me or do florists not understand geometry?

[QUOTE="BillTre, post: 6533248, member: 581757"] I have heard this before somewhere. This much makes sense to me. A clean cut on the bottom of the stem will allow the stem to take up more water. The opposite would be to crush the outer surfaces of the stem together until it is pinched off. In the second case, the micro- or just bigger then micro- channels through which the water would enter the plant remains (cut-off flower) would be crushed together leaving little or no opening for the water to enter the ascending channels. In this case the flower would be expected to dry out rapidly. The alternative would be to ensure the ends of the channels (basically made of delicate cellular products, on a very small scale) remain open so water can freely enter. Their delicacy can be gauged by how easy it is to crush the flower's stem. [B]Comparison of cutting methods[/B] (this is a lot like doing histology, preserving biological material and (usually) slicing it up to look at under a microscope, without messing up it's microscopic structure, something I have done a lot of): [B]Crush till broken[/B]: no good, channels crushed closed [B]cut with scissors[/B]: scissors can produce some crushing locally before the cut happens. [B]Cut with blade[/B] (normal histological method); should not crush unless you are cutting by pushing down on something. [B]Cut with blade at an angle[/B]: Cutting at an angle could allow easier cut without pushing down on something. It would be like whittling the end of a stick to a point by countering the force of the blade by keeping it from pulling the stem away from you. I would guess this method would result in the most open channels, most frequently. Testing for open channels and water transportation: There are experiments for kids involving celery and food coloring in water (actual childhood experience). Celery have very large channel going up the outside of their stems in which the food coloring can be distinguished by the naked eye. You could test: [LIST] [*]break vs. cut [*]crush vs. scissors vs. blade vs. angled blade [/LIST] If you want to try it on an actual flower, look for a kind of flower where the veins could be easily seen on the outside of the stem [/QUOTE]
