What is a good fertilization regimen for a garden of alliums?
Every time I read an article off Google I feel as though I know less; there are so many conflicting opinions and I only got into fertilization this past year.
I currently have 25KG bags of Gypsum, 16-16-16, and 5-20-20.
Is 5-20-20 and gypsum at the time of fall planting (for root growth) followed by 1-2 applications of 16-16-16 until the first week of May a good regimen?
