CINDY DAY: Seedy summer forecast - when to plant?

Ah local tulips! Too early? Not really.  This beauty was grown in a greenhouse at  Vanco Farms on Prince Edward Island.  Michele Lawlor agrees that it might be a while before their field grown tulips are ready to be picked.

Last average spring frost dates for Atlantic Canada

Last week, I got an email inquiring about “last spring frost dates.”  At first, I thought this guy is really too early, then I read more:

“Hi Cindy. When I read the directions on my seed packages, they suggest I start six to eight weeks prior to the last frost of the season. Can you give an approximate time of the last frost to assist in my planting?  Sincere thanks, Kevin, Gold River, N.S.”

Great question Kevin and as it turns out, very timely.

On average, the last frost in the Gold River area occurs between May 11 and May 20. Kevin can plant those seeds anytime now.

If you’re starting seeds indoors, have a look at the list of “average last frost dates” for a sampling of locations across Atlantic Canada.

Calculations are one thing, experience is another. Many people believe you do not put any delicate plant material outside until after the last full moon in June. Last year, as you may recall, that would have been very wise. 

This year, the full moon for that month is on June 17.

Happy garden preparation!
