Q.My Korean Spice Bush
My spice bush has not flowered, lots of buds… it is 2 years since i planted it..no flowers..is healthy and has grown in a good location. Do I need a pollinator to have it flower, if so and what is compatible?? I live in zone 5.. Does it need a few years to get established and flower?

It blooms on old wood (buds develop the previous season), so if you have buds that don't bloom, they are getting nipped by late frosts as they are preparing to open. They are hardy to zone 4, but may need some winter protection, especially from cold winds. Make sure it isn't pruned till after it blooms.
