 CULM - LoveToKnow Article on CULM
Thus the English Culm measures comprise an Upper Carboniferous and a Lower Carboniferous group, while in Germany, Austria and elsewhere, as it is important to bear in mind, the Culm, or Kulm, stage is shown by its contained fossils to belong to the lower division alone.
This aspect of the Culm is found in Saxony, where there are workable coals, in Bohemia, Thuringia, the Fichtelgebirge, the Harz, where the beds are traversed by mineral veins, and in Moravia and Silesia.
Culm fossils appear in the Carnic Alps, in the Balkans and parts of Spain, also in Spitzbergen and part of New Guinea.

 "Bamboo in Nepal: A Management Guide" by Robert I Bradshaw
The culms should be more than 3 cm diameter and have strongly developed side-branches (at least half the diameter of the main stem at their bases) and leaves (Storey, 1989a).
This usually means that 2 year old culms should be used, but this depends on their position in the clump (Storey, 1988a) [See also 8.1, i] Only bamboos which produce aerial roots will grow from culm cuttings (Stapleton, 1987; Gurung, quoted in Storey, 1988b).
The culms should be severed by cutting round once with the blade of a hasya (a curved pruning knife shaped like a small sickle) angled at 45 degrees to the stem, then again with it angled the opposite way to produce a wedge-shaped notch.

The culm is used for processing in manufacturing or used wholly (Wang 1987; Zhu 1994).
At the beginning of young culm growth the upward growth rate is small, but the horizontal growth rate of the internode is pronounced.
At peak time internodes grow fast and steadily, at this time the culm sheaths at the base of culm begin to fall, the upper braches begin to spread and the culm growth rate slows down.

Culms are cut after they reach 7 years so that only about 500 shoots per hectare are allowed to grow into new culms each year.
Culms are more or less cylindrical in their lower section but in the upper parts each internode has a broad groove on the side from which the branches emerge.
The surface of the culm is smooth, green, yellowish green or yellow, and the internodes are relatively short.

 Cane Prep - Testing
For some unknown reason, certain culms (though very few) will exhibit this "softness" between nodes, but when it exists, it is usually in only one such internodal area.
Select any one of your split-out strips from a given culm and, before soaking, simply give EACH internodal area in the strip a good bend between your hands--feeling for the desired resistance.
The bend-test is a "relative" sort of thing (like the "heft" of a good culm), but you will very quickly gain a sense for the feel of really good cane.

 ABS - Bamboo Mealybugs
Culm injection of sytemic pesticides is a method used in China to control sap sucking and some leaf chewing insects One advantage of culm injection is that there is almost no wasted pesticide released into the environment.
To use this method, drill a small hole into one internode on each culm, then use a syringe to inject 0..25 ml to 1.5 ml (the amount depending on size of the culm) of full strength Cygon 2-E (23% dimethoate) into the culm.
When first using this method, test it out by injecting one or two culms to determine the appropriate dosage for your bamboo species; different bamboo species can vary in their sensitively to injected Cygon.

 ABS - Frequently Asked Questions (FAQ)
Bamboo culms (stalks) reach their maximum height in the first growing season and then, each year after that, usually add branches, until the culm is five to seven years old.
The culms should be mature (four to eight years) and should be harvested in the dry season.
Once the culms are harvested they are best placed in a well-ventilated, covered, shaded area, avoiding direct wind or sun as a quick drying may cause splitting.

 Cane Prep - Cutting
Some culms will suit particular lengths of rods depending on the distance between nodes if you are concerned about not having nodes in the top 5" of the tip and not at ferrules.
The important thing is that by measuring down from a node, and selecting the culm sections that suit a rod length you can usually reduce the number of nodes in a section as well as keeping nodes away from the ferrules.
Also a reason for not cutting in the middle is that the power fibers decrease as you go up the culm and if you can use the lower section of the culm and discard the upper section you will have more power fibers.

Improvement of agricultural land by drainage and use of fertilisers and current neglect have caused Culm grassland, a species-rich wet grassland community in south-west England, to be under threat.
Culm grassland is nationally known as Rhôs pasture and can be described as a mosaic of the following NVC communities: M16, M23, M24, M25 and M27, which vary from wet heaths to rush pastures.
Insight into hydrological functioning of Culm grasslands is obtained by modelling the hydrology of the Wolf and Thrushel catchment in Devon, using a semi-distributed hydrological model.

Skis that will never touch snow (unless it is out by the curb) and very durable abrasion resilient gear are preferred, as the culm, being comprised of rock, provides a less than comfortable surface to go rolling around on.
