This year, we did the math.
Onion plants from Dixondale Farms, 6 bunches: $30.72
The more bunches you buy, the lower the cost.
If you don't want a lot, see if a friend will go in on an order with you.
Harvest: 43 pounds.
Note that this does not include the quart of roasted green onion tops, nor the ones we pulled early as scallions, or the ones we gave to our daughter to plant.
Soil Amendment: Free horse manure and about 50 cents worth of bone meal. Though that's probably an over estimate.
Recently our local organic market had onions on sale for $3.69 for a 3 pound bag.
Plain yellow onions, no choice of variety.
No freedom to choose based on flavor and storage capability.
No green tops!
The freshness and freedom to grow the kinds of onions you want organically, plus the perks of roasted tops?
