May have made a mistake...

So I know you're supposed to use a special seed starting mix for seedlings. And I know that no fertilizer should be in the mix right off the bat.

I went to HD knowing this, and still accidentally came home with fertilizer in my mix. oops. And I didn't realize it until after I planted my first batch of onion seeds.

The mix is 'Schultz Seed Starter plus, with extended feed plant food'. It say's it promotes seedling growth, but I'm not so sure. Sooo... will the fertilizer hinder the seeds from sprouting, or harm them down the line? I'm at a point where I haven't planted too many yet and can still switch if need be.

That starter mix has very weak fertilizer like transplant fertilizer and will not hurt your seeds or seedlings. Use it--it's fine.Shultz is a good name, next time if you want one without fertilizer get one that doesn't have the plus. Plus usually means fertilizer.

What you don't want to use is a plant mix with time release fertilizer. Full strength fertilizer is detrimental to seedling growth, but not sprouting.

'Schultz Seed Starter plus' - addition of an extended slow release fertilizer according to the product description, oilpainter.

Kim, I don't use this, I prefer to add my own water soluble product, diluted, as needed. But it must be formulated for tender seedlings - I find good reviews for the Shultz Plus brand, no statements of complaints about the fertilizer being too strong, somehow detrimental. It doesn't look like by using it that you have anything to be concerned about.

RE: May have made a mistake...

Whew. Thanks, both of you. Good to know.

As I'm learning, companies in the "seed" business don't always sell what will work the best (i.e. peat pots and extra tall domes for seedling trays) :)


RE: May have made a mistake...

morz8----Yes it is slow release but a more like transplant fertilizer than Osmacote. Transplant fertilizer also has a rooting hormone and so does this seed starting mix.

RE: May have made a mistake...

No personal experience with it and likely wouldn't buy it but since you have it why not do a bit of an experiment with it and then let us know how it works. Do you have another plain mix you can use for comparison?

For future reference plain old Jiffy Mix at Wal-Mart or Home Depot is just $4 a bag and works fine.

Better get those onions going as it is getting late for starting onions from seed. In your zone I hope they are a long-day variety?
