Javid and Nikitski Almond from Englands. Grafting?

@Buckeye

Do you notice a bloom time difference between oracle and javids?

I have an oracle and nikita’s pride that are a few years older than the javids , but they bloom about 4-5 days earlier than the javids and have never produced any fruit. I think it’s a late frost thing and those few days make a difference. This year the frost was really late and nothing produced.
