my whole lawn (100sq m) has died leaving only some moss behind. it was very luscious as i fed it lots during summer. it was laid three years ago. I assumed it is leatherjackets doing damage as roots have turned to soft fibrous compost (last year i had to really spike hard and this year spikes slid in no problem)i ordered nemesis but was away when it arrived and it sat for 2 weeks on my mat - i live in Scotland and it was cold with no heating on..... but i know it is supposed to be in fridge. i applied it last week and am not sure if it is going to be effective. it was like a soft brown cotton wool like substance - like candy floss. i raked the ground first and then re-seeded ground and covered with light covering of sand and soil.
how can i tell if it is effective? will it effect new seed? should i buy some more in case? it had an expiry date of end May on the box. I assume it has a very short shelf life?
