mandolls said:This is only my 3rd year growing potatoes. I am looking for tips on fertilizing them. I put in about 25 yukon golds, each year, and the plants have always looked very healthy, but they don't always make a lot of potatoes. Usually anywhere between 3 and 5. I have them in a deep raised bed with good soil, and have usually only fertilized a few times with Drammatic - K, a fish kelp fert. Should I be bumping up the potassium even more?

I dig them in really deep, about 12", then fill in behind them as they grow, and hill up the soil a bit when they get above ground.
I may be planting them to close together, but they never seem to be crowding each other out (about a foot apart, which is what I saw recommended for Y.G.'s))

You do not have to hill them in a raised bed, or anywhere, to save time and labor.
Just plant deep and fill the hole/trench.
They will come up and produce potatoes just fine without hilling. I plant mine as deep as yours in heavy black-gumbo and they simply come up fine though before I used leaf mulch to cover the plot after planting I did hill some to cover potatoes breaking the surface.
12 inches is the spacing used by commercial farms as they generally do not want large over sized potatoes.
I plant mine 16 inches apart because I want large potatoes.
Potatoes do not like crowding, closer together the smaller the potatoes.

Here is an organic formula but for potatoes close is good enough , usually.
