Living in ct I was never able to get onions to grow larger than 1-1.5 inches.
Can anyone tell me what they do to get large onions. When to plant, what type of onion, fertilizer, watering....etc..
Thanks in advance.
There are several items essential to large onions:
- Buy onion plants as opposed to sets
- Grow a long day variety in CT (Walla Walla works very well)
- Plant at the right time (for CT that's around April 15)
- Give them room, spacing onions 6" apart in rows that are 12" apart.
- Fertilize with a high nitrogen fertilizer for strong top growth, starting three weeks after planting, then every month ending in mid May.
- Keep the onions weed free - they do not like competition. A good mulch helps.
- Water at least 1" per week - onions like water.
onions like a very light soil around them. What I do is use a hose end sprayer and wash most of the soil away from the bulb so it is just bearly there. if planted too deep they will stay small no mater what.
I agree with TomNJ but I plant mine in a wide row of 4 on 10 inch centers.and I plant them to the depth of the first joint on my index finger.Walla walla is a very good onion but the regular candy will keep longer.Everyone gardens a little different experment a little and do what works best for you!!! Good gardening to ya!!! YOPPER
