We had several days of snow in April, but now we are up to 15 hours a day of
sunlight, with a couple hours each of dawn and twilight on either side
of that. Now things are finally getting warm and the grass is taking off. Spring is always like this... You might have t-shirt weather one day and a freeze after that.
I usually
get caught off-guard turning the sprinkler system back on as well.
Spring is sometimes very short-lived or just weird up North. Earlier this month it was time to mow and weed-whack for the first time, and that's when the problem came up.
