Have your garlic gotten to that size before? I use a mixture that includes the Neptune once a week, but mainly I depend on getting those micros in via the amendment mix. That has precisely what is missing, as I make it according to the soil test.
Peas were officially planted yesterday, a week later than I wanted to do it. But it's done.
I've gotten the bulbs to about palm size (I have pretty small hands though). The year I got them that big was the year I planted them straight into a huge amount of composted cattle manure and hit them hard with bonemeal and Neptune's Harvest. This year I have a variety of garlic that I am super excited about, Music, that's supposed to yield well and be largish....as always, we will see lol!
And I planted my peas way later than normal due to the cold weather snap, glad you got yours in!! Now we just have to hope we don't get 90+degrees in June lol!
