Tiny Tim Tomatoes in 4" pots

Hi All,

  This is a project I'm doing for an online course (greenhouse management).  This shows the development of tomato plants with Osmocote as fertilizer, toms watered with soluable fert (miracle grow), and no fert at all.  The osmacote tom has set a tom!  The MG plant looks good.  The non fertilized plant is about to keel. I really am surprised about the osmocote plant.  I'd like to test it against organic ferts.  I am, however, having a massive fungus gnat problem!

Beth

PS.  I did get my Horticulturist Certificate from University of Guelph (with Distinction).  It was a good experience.  Not really happy with the greenhouse management course - not much student interaction.

Good to know, thanks for sharing, Beth. Yeah, I thought seedlings couldn't cope with any fertilizer beyond 1/4 strength, so wouldn't have thought to use the slow release stuff. I do have some - both MiracleGro generic (same as embedded in potting mix, I think), and some Dynamite flowering/fruiting stuff that I add in little piles for pseudo-GrowBox-fertilizer in containers.

Hi Gisette, Thanks!  The

Hi Gisette,

Thanks!  The intent of the project is to show that for greenhouse operations, it is easier to add a slow release fertilizer when starting seeds than to have to apply fertilize at each watering.  I was skeptical that the slow release would work for seedlings, but darn, it is easier!  I never add fertilizer when starting seeds.  I wait until they have true leaves. Then I forget to fertilize half the time.   The down side is cost (for greenhouse operators).  I may rethink my seed starting next year.

Congratulations on the Horticulturist Certificate, Beth!

What's special about "Osmocote"?
