![]() ![]() Others look at it as getting two carnivores for the price of one, especially when the bladderworts bloom in spring.) Most aren’t a particular problem, but many varieties of invasive marsh grass need to be cut back before they’re impossible to remove.Īs mentioned before, the biggest problem with grasses and ferns is the root system. Some of the invasives can even be other carnivores: sundews are famed for spreading seeds far and wide, and some people complain about the number of bladderworts that take over carnivore collections. (Because of years of use of New Zealand long-fiber sphagnum, Triffid Ranch enclosures tend to get a wide range of native New Zealand ferns sprouting at odd times.) Outdoors, the main pests are marsh grasses, which attempt to produce large root mats on the bottom of pools and pots. Likewise, in indoor enclosures, the main invasives are ferns, which are either cosmopolitan species whose spores moved on the wind or ones endemic to the area in which the sphagnum was collected. For instance, most sphagnum has plenty of sphagnum spores, and if cared for, this can be a dependable source for live sphagnum moss. Give them the right conditions and they’ll come right up, and if not kept under control, they’ll take over and choke out the carnivores with whom they share space.Įxactly what comes up depends upon the source and the general conditions. ![]() Whether it’s long-fiber sphagnum for top dressing or milled spaghnum for large pots, even ostensibly sterilized sphagnum has unavoidable seeds and spores, sometimes ones preserved within the peat for decades or even centuries. Since almost all carnivores need moist and acidic conditions, that means that the overwhelming choice for potting mixes involves peat. One issue with raising carnivores that doesn’t get as much coverage is the issue with weeds.
