In previous experiments I grew Red Lion amaryllis bulbs in 7:1 ratio of water to vodka 80˚ (40% alcohol by volume) and achieved a pretty stout, self-standing, amaryllis bulb growing indoors on liquid. The control on plain water grew tall, spiked well but — as is typical — the foliage fell over and needed support (see suggested reading links below).

My aim now is to see how much larger and taller I can sprout an amaryllis bulb on a dilution of alcohol before the foliage gets leggy and the leaves topple over: I want to determine the minimum dilution of alcohol to use for maximum results.

The original ratio of 7:1 vodka 80˚ (40% alcohol by volume) to water is 1/8th of 40% or just 5% alcohol. This year I’m trying (a) weaker dilutions of alcohol to put less stress on the growth — 4.1% and 3% respectively — and (b) I’m using less expensive and more easily obtained isopropyl alcohol rather than the ethanol or grain alcohol I used in all my previous experiments.
