A couple of trees near me have already come in to blossom with no leaves yet
Yeah, some species do that. Nice photo op.
The bokeh is not too distracting in the first two shots, but the flowers that fall on a white patch do not stand out very well; which is the real trouble. I actually enjoy a mottled backdrop from time to time, as it suggests structure.
Careful composition and patience will usually lend you an angle where things are just right. Also look at longer macro lenses, like 150-200mm, as they have a narrow field of view (same depth of field mind you) and often a better bokeh for it. Sometimes fancy a creamy featureless backdrop, sometimes not.
Either way, your sensor needs a clean. I see some dust.
