so this is the first year ive grown true onions, they are spaced 8"-10" apart and fattening up nicely. my concern is the tops have gotten so big they are falling all over themselves, creating a pretty thick mat of stalks laying on the bulbs. im afraid this mat may start to rot and/or choke out the bulbs. should i trim? will the tops keep growing in a healthy manner if i just let them go their crooked ways? anyone know what im sayin? thanks, steve
