Pumice and
the Oregon nursery industry in Digger (Oregon
Association of Nurseries, June '05) discusses the
similarities and differences between pumice and
perlite. "Pumice
is a porous and lightweight rock similar in appearance
to perlite. . . . Pumice is a type of igneous rock,
which is formed from molten or partially molten material.
. . . Perlite is a glassy alumino-silicate mineral
of volcanic origin. The raw material is crushed and
exposed to high temperatures (1,600 ° F), which
results in expanded, white, lightweight particles.
During the heating process, perlite is expanded from
four to 20 times its original volume. Perlite does
not compress and consequently promotes good porosity
and drainage. Because of local availability of pumice
in the Northwest, it has replaced perlite in most
commercial mixes.
Taking
your business to the next level with the help of good
company is
the "Business
Management" feature
in MNLA News (Minnesota Nursery & Landscape
Assn, June '05). Advice includes, "Keep a list of experts
on file and reach out to them for advice, feedback,
and to bounce creative ideas off of when brainstorming.
If you don't already have a list of informal mentors,
seek them out at networking and speaking events, company
web sites or business-focused blogs." The author, Richard
Kroll, CFP, also recommends selecting your customers
carefully. "Create a customer base that feeds your
goals-and not one that distracts you from opportunities
in the best interest of your company. . . . Taking
on clients aligned with your expertise, moves you closer
to reaching higher business goals as well as unearthing
beneficial new prospects."
