Hi Mrs W,,,,
If you grew them this spring
~ they are still young. My hope for you is that that survive your NY winter and will come back in the spring
at which time they should begin blooming ,, In the spring
give them a good boost of fertilizer to give them a jump start..
IF you have had them for over a year I would certainly give it a good boost of fertilizer to encouage it to bloom ~ Preferable a fertilizer with 3 #'s and make sure the middle # is a higher # than the other two which tells you it is going to reallly encourage blooms!!
