Narrative:

At 50 ft [AGL] on landing at bos on a visual approach runway 04L; encountered a significant rolling motion caused by jet blast from a heavy aircraft that just departed from runway 09. By the time I was able to correct the rolling motion we were through it and still on a visual glidepath for our landing runway. I continued for an uneventful landing and rollout. Tower was notified after we landed.suggestions: tower can not depart aircraft on runway 9 with an aircraft on very short final for runway 04L.
