Containers
Nepenthes can be grown in a variety of containers,
but plastic pots are generally preferred because they are
economical,lightweight, and come in a great range of sizes.
Most Nepenthes will do well in a one-gallon pot,
but some of the larger species (N. bicalcarata, N.
merrilliana, N. sumatrana, others) require containers
of 4-5 gallons to reach full size. Seedlings and young plants
can be grown in 4-6 inch pots or trays. Clay pots, though
attractive, are avoided by many growers due to the belief
that they accumulate harmful salts and chemicals. However,
experience shows that healthy Nepenthes can be grown
for many years in clay pots, especially if they are given
high-qualtiy pure water. Containers should always have sufficient
holes to permit rapid drainage and good soil aeration. Hanging
baskets and pots are an excellent way to display larger specimens,
and allows for the trailing vines and tendrils to grow without
support.
Soil
In the wild Nepenthes grow on a wide range of substrates
ranging from clay soil to mossy tree trunks. Fortunately,
it is usually not necessary to duplicate these conditions
in cultivation and a single general compost with few variations
will suffice for most species. A suitable potting media for
Nepenthes should be well-drained, slightly acidic
and poor in nutrients. Most growers prefer to mix their own.
A simple well-balanced mix can be made by combining equal
parts of organic and inorganic ingredients. These provide
some moisture retention whilst being low in pH and relatively
nutrient-free. Inorganic materials such as pumice, perlite,
sand, granite chips, and clay pellets help to increase drainage
and soil aeration, which is an important factor in the growth
of healthy Nepenthes roots. The addition of one part
charcoal chips assists in aeration and may aid in preventing
stagnant media. |
