Not sure of the year but remember it. Looking at my records, my last freeze in 2016 was on 4/21. In 2020 the last freeze was 5/14 and it was on 5/15 in 2023, maybe one of those years?
I've always done better working in the lawn later in the season, less competition from weeds and birds eating the seed. Just have to hope to get some rain too and not a dry spell in September.
Agreed, I live in an old ass house (mid 1800's)with poor insulation and it only got to 70, windows closed, on my second floor yesterday after a high of 86.
