Q.Hawthorn ‘Winter King’ blooming
Will my Hawthorn tree correct its bloom time next year? I purchased a Hawthorn ‘Winter King’ from a nursery that was in bloom already in April. I have two Hawthorn Winter Kings that I planted it with that only began blooming now at the end of May. Will all three bloom at the same time next year?

It will go dormant at the same time as the other plants and should began it's spring growth at the same time as the established plants.
The age of the plants will play a part in it's blooming patterns though.
