Q: How often should I feed my Venus flytrap?
Dionaea 'Dentate Traps'
A: This depends upon the plant. You can put a bug in any trap leaf that
is open. Once a trap captures a bug, it requires about a week to
digest it. Then it will reopen and be ready for a new bug. This means
that if you have a large plant with about seven traps, on the average
one trap will reopen per day, ready for a feeding. This is a lot of
work.
On the other hand, you do not have to
feed a trap right away just because it opens.
Traps can go for weeks without being fed. I have grown entire plants for
more than a year at a time without feeding them. They grow fine, just
more slowly.
I usually feed my plants about four times each year. Each plant gets about three bugs per feeding. Twelve bugs per plant doesn't seem
like much, but I have about 30 plants in my terraria, so that comes to about 360 bugs. That's a lot of time spent chanting Poe in my
living room, when I could be off teasing my neighbor's cat.
