Growing large storage onions has been challenging. I yearn to grow large onions and use them throughout the year.
Spring onions? No problem. Larger red, yellow or white, the kind we most use in the kitchen, have eluded me.
I’m determined this year will be different. Toward that end I’ve launched some experiments to see how I can do better.
Friday, Feb. 7, I planted Talon Yellow and Red Burgundy onions at home from seed. After six weeks the yellow germinated, the red did not. After chatting on line with another grower, they pointed out fresh onion seed is important. The Talon Yellow seeds were this year’s crop from Johnny’s Selected Seeds and Red Burgundy were end of season discards at the home, farm and auto supply store. Lesson learned: get fresh onion seeds.
That same day I split my Matador shallot seeds with the farm. They are growing their half in the same environment as the rest of their onions, I started mine in a tray at home. Mine don’t look that healthy although they germinated. If the targeted planting time is mid-April, there is time for them to grow and hopefully survive transplant. I’m looking forward to comparing results.
I bought red, yellow and white onions starts from the home, farm and auto supply store. These are the same variety I bought every year since working there. I divided them roughly in half and planted some in soil blocks to give them a head start, and reserved the rest to plant in the ground as soon as it is tillable.
This year I ordered some onion plants from Johnny’s Selected Seeds. They are to be shipped in a couple of weeks and then direct planted in the soil. The varieties are Ailsa Craig, Patterson and Redwing. While more expensive than seed at about 30 cents for each plant, I’m hoping to find something that works in trying it. I would much rather grow everything from seed yet I want other options as back up.
Finally, this morning, I planted six 3 x 3 containers with White Lisbon Bunching Onions from Ferry-Morse (60-110 days). I mixed both pelleted and non-pelleted seeds and broadcast them in the pots. If they germinate and grow, I’ll transplant the entire pots as groups of spring onions. It is a month behind where they should have been started, so we’ll see what happens.
The last part of my experiment is twofold. I am researching types of soil nutrients which support onion growth. My normal process is to hand till composted chicken manure into the soil before planting. If the several garden books in my library suggest another approach, I may try it as long as it is not a commercial, chemical fertilizer. This year I bought a small tiller which will break up the soil more thoroughly than handwork.
I am also planning a disciplined approach to watering and weeding the crop once it is in the ground. Because of our climate, I plan to mulch the crop to retain moisture in the soil. Weeding and regular watering has proven to be challenging, partly because weeding gets away from me and partly because my approach to watering is sparing. With a framework of “experimentation” perhaps I can do better.
I know growing storage onions is possible as I get them from the farms each year. With effort, maybe I can grow my own.
