Soil amendments for garden

Post by Dargin » March 27th, 2019, 4:11 pm

I have a bunch of seedlings (amaranth, foxglove, larkspur, morning glory..) I'll need to transfer to 4" containers shortly. I'm still trying to figure out how I'm going to handle ammending the soil in the new pots (a mix of peat, coir, perlite, compost). I plan to use bonemeal for P, green sand for K, and bloodmeal for N. I'm not sure how to handle calcium and magnesium. Should I use dolomitic lime? Calcitic lime with Epsom salt? CALMAG? Not sure what works best.

Also curious what anyone thinks of greensand as a source for P. Should I go with SoP instead?

Appreciate any input. Hoping to have an army of amaranth this summer.

Are you going to grow these plants in pots all summer? or just temporarily? Why not just purchase some potting soil?

This is similar to asking "my car is broken - what part should I buy?". There is no way to know what is lacking, and therefore what product(s) would help.
