    When to fertilise seedlings?

    Title says it all. Got a pod's worth of seedlings which have sprouted (mother is N. jacquelineae), seeing mostly cotyledons so far although a couple are starting to develop their new leaves.

    I've got a urea free orchid fertiliser that I've been using on my neps with success so far, when should I start giving it to the seedlings and at what strength?

    I usually start fertilizing Nepenthes before they've even sprouted. After sowing, I generally water them in with a misting of Maxsea at a teaspoon per gallon. After they germinate, they get a monthly dose just like the larger plants.

    I've always started fertilizing as soon as they start growing their first little proto pitchers using the same fertilizer (sometimes a 30/10/10 urea free orchid fert or maxsea 16/16/16) and concentration (usually a 1/4 of the label suggestion) I do for my larger established plants. I've always had good results with this regimen.

    Wow, I'm going to have to try this on the next batch of seeds I come across, thanks!

    As a rule of thumb, I generally wait until about the second set of true leaves -- past the cotyledon stage; and I've never found the application of fertilizer before germination to be effective. Under humid conditions, it can all become an anaerobic or algal mess far too readily . . .

    Thanks for the recommendations guys, I suppose it's good that I've got the seedlings in more than one container. Think I'll try fertilising one batch now, then another when they've grown more, see how it goes.
