I did the same as well last night, well..let's be honest here, I check them all the time! But after all the talk of trees breaking dormancy, and our unseasonably warm days we have had lately made me want to check them a little more thouroughly. I can say I finally found a bright side to having a north facing driveway, it keeps the garage a little cooler during warm spells. Although I put some snow on the pots last week, I decided to go out front to the mini glacier snow shoveling pile and chop out some nice heavy granular snow chunks and lay them on the pots to keep the roots chill. I'll have to call the wife and make sure she keeps the garage door shut today, 70 degrees warms up the garage fast.
