Gnats and springtails when I happen to see one while checking on the plants, but amount of gain from those seem to be somewhat less than betta fish pellets crushed and placed onto the leaves. The amount I used is dependent on the size of the leaf. Using the crushed pieces, I've actually not had much burning or die back of leaves as I originally thought I would have, but regardless, I never attempt to feed the same leaf. Occasionally, I've been as bold (or lazy
) as to just stick a whole betta pellet onto a filliformis leaf and even then, I haven't had it burn (full grown filliformis, I wouldn't suggest people read this and stick a pellet onto a seedling). I've yet to try that amount on other dews however.
When I soil feed, it's usually a low concentration in a spray bottle. This is mainly to allow for me to spray the leaves gently as well. Not sure how much noticeable benefit this has on the sundews, but I have tried this on many with little ill come from it over the past year. I emphasize that the dosage is very low though (about a 1/4 - 1/8 of recommended concentration).
And to conclude, I leave the usual disclaimer - what works for me may not work for everyone (especially as it pertains to ferts) so proceed with caution and happy growing
edit: On a side note, I am planning on trying osmocote on the regia. I believe this has been tested with adult plants, but not sure I've read it being done with seedlings/plantlets. I could be wrong. In any case, worth a shot to see if my soil feeding lack of results is merely due to the dilution of the ferts I use. Osmocote pellet should be a bit more of a kick to the plants system I am hoping. Time will tell.
