Science Experiments

IMG_0283

I’m doing an experiment to test whether a teeny bit of fertilizer helps or hinders seedlings in Orta pots.  You can see that I’ve labeled one side of the pot “Fert.”  The three pockets on that side of the pot have a bit of organic fertilizer added to the potting mix (about a teaspoon of organic fertilizer to a quart of seed starting mix).  The other three pockets just have the basic seed-starting mix that I make from a recipe I learned from Root Simple, a mix of coconut coir, perlite, and worm castings.  You can find their original post here.

They suggest watering seedlings with a very dilute solution of fertilizer when the seedlings are about 3-4 weeks old.  Because Orta pots wick water through terracotta walls instead of being watered from above, I thought the seedlings might be happier with a bit of fertilizer already in the seed mix.  In another posting, I’ll test what happens if you put dilute fertilizer solution directly into the water reservoir.  Will the nutrients pass through the terracotta?  That’s a question for another time.  For now, I’ll keep you updated about what happens with these little guys.
