Question
Hi! I live in Nova Scotia.  I started sunflowers in peat pots and I think I started them too early maybe?  They're about a foot tall and higher and I won't be able to plant them until some time in May I think.  Will they survive until then?

Answer
Sunflowers cannot tolerate frost.  I always recommend planting them one week following the last expected frost for your area. I personally direct-seed sunflowers sometime in mid-May. They are very fast growing and often bloom by mid-summer.

At this point there is not much you can do other than pinch the tops should they start to get spindly.  This will promote a more stocky growth habit, and will enable you to wait until the end of May to transplant them.

I hope this answered your question. Please let me know if I can ever be of assistance.

Regards,

Mike
