No. It has rooting hormones and I don't think that one would want that on
their CP leaves.

Yes. 1 drop per gallon in all water (that is not sprayed, I occasionally
sray deionized water though)

> Would you use it on newly rooted cuttings?

Yes. That is one of its best applications as it contains vitamin B1 to
help minimize the effects of transplant shock.

> How often do you use it?

All water that is added to the trays is a 1 drop per gallon solution.

Sometimes I'll use a stronger concentration on transplants that are more
_mature_. I find that a 10% strength solution often brings out red
colorings. Some Darlingtonia roots for example turned red after 4 days
of being in their original plastic bag waiting for the actual
transplantting. Sarracenia Minor petioles turned fuschia pink as did
Drosera Intermedia and Dionea Muscipula petioles. (At first look I
thoght the Intermedia was dying but closer examination revealed that the
petioles were pink and not brown!)

One caveat, the Dionea were young plants and were _sprayed_ with the 10%
solution as well. Those same Dionea leaves turned red-edged and died
prematurely. The plant is still alive however and doing fine.

One more tidbit; my brother said that his Darlingtonia got some red
highlights after putting a few nails in the soil. I put a few nails in
one of my Darlingtonia's soil and got similar results. I figured that
since acidic soils can ionize metals into solution rendering them victim
to being leached out of the soil, that the reddening of the plants has
something to do with the iron from the nails being oxidized and
released. Are there any technical informants to support or refute this
reasoning?

Good growing to all, Eric Kamakea
