porkchop I see that you're not getting any responses here. I can't be of much help (like my Vermont compost answer lol) but this is what I have to offer.

I am not a big fertilizer person at all. I have only recently started using hollytone for some of my evergreens, and every once in a while will fertilizer my tomatoes, or my annuals, and a few years back when I was growing flowers for my daughter's wedding, I did try to adhere to a fertilizing schedule for my dahlias.

Usually, it's a time thing. I just don't have time to keep to a good schedule.

However, when I DO fertilize, I always use an organic fertilizer, and it's usually seaweed or fish emulsion. I am always a bit hesitant because I don't want to attract critters, but so far I haven't had many problems.

Those times I fertilize I do usually buy Neptune's Harvest, but the thing is, I am not attentive enough to really see whether plants do better with the fertilization. I often start off in spring with it and then peter out, and I don't keep any kinds of records or notes to mark results or comparisons.

I will say that seaweed and/or fish emulsion was one of the main fertilizer choices of growing folks in my circles when I worked for an organic farming association. And many of them did use Neptune's Harvest.

I don't know if this helps but I wanted to try to contribute SOMETHING that might help you out.

Good luck!

I've used it a couple times so far at 1/2 strength on some rooted cuttings. They seem to look perkier but I have no objective measurement of that :0) I'll have to see how the seedlings do this year.

The best seedling fertilizer I ever used was ROOTS liquid fertilizer, Gardeners Supply used to sell it decades ago but I've never seen it since. I've often wondered if it is some sort of sort of product like Neptune's, or even Neptune's re-branded, which is one of the reasons I wanted to try the Neptune's -- I never found anything that compared with whatever that stuff was.

I've used similar fertilizers on seedlings. Should be fine if diluted to maybe 1/4 of recommended strength.

I use only organic fertilizers too. I use seaweed emulsion all the time. I bought a sprayer and i use that to fertilize my full sun garden and sometimes even the lawn. I haven't used it for seedlings so I didn't post here. [g] But I am sporadic with seed starting anyway, but I do see a difference when I use it. When I grow pots of annuals, I don't feel the Seaweed fertilizer is enough to keep them blooming well all season. But I've yet to buy an inorganic fertilizer to do the trick. I'm going to try to be more consistent with the seaweed fertilizer and containers this year and decide if I need more. Seedlings I leave on their own without fertilizer and plant them out when they are still small if possible. That's just me.

Are you using the seaweed only version? The seaweed fertilizer wouldn't be enough on its own if it doesn't have much nitrogen in it. The fish-seaweed blend does have N.

Yup, I use the fish/seaweed combo. Which is great for everything except pots of annuals.
