Dear Mary Sue, Lauw, Sorry, for not replying to your last email sooner, had a few minor = problems with my hard-drive this week, all fixed now. Back to the subject of the plastic bags. I find them easy to handle, they're strong and lightweight, last for = years, UV treated, easy to handle, shift and store, they come in every = imaginable size from 1 up to 90 PB, they are ideal (the 40 PB) for deep = rooting large bulbs, which can be left for a number of years, a big = advantage for the more temperamental species like e.g. Brunsvigia , that = don't transplant well. Than of course there is the price, they're relatively cheap, especially = when you handle thousands of these plastic bags. I use mainly the sizes 8-12-18-30 and 40. PB of course stands for plastic bag, but the numbers, intriguingly go = back to the now abolished imperial system when they measured everything = in pints. So a PB 40 equals: 40 x 0.568 liter =3D 23 liters, or 40 x 1 pint =3D 5 = gallons in volume. The PB 40 when full, measures 30 cm (12 inch.) wide and 34 cm (13.5 = inch.) deep. Trust that will explain and satisfy your queries. Best wishes, Bill D, btw:///great/ excitement in our nursery, the Worsleya rayneri is flowering = at the moment, will post a picture shortly.
