Allotments 4 All

Hi All, I am planting some Japenese onions and hoping to cover them with fleece when required. The flece is huge and I wondered if I could cut it to size and would it be alright. Or would I need to use heat gun. Any advice would be most welcome. Thankyou

Hi lezelle
Fleece is fine if just cut. No need for heat gun. Is this to keep allium leaf miner off? Japanese onions are hardy so not needed for insulation.
