Cogshall is a pretty early mango actually. This year, for some reason, it has been a slow bloomer at my house too. The very top of the tree has now come into full bloom, a full couple of weeks to a month behind other trees. The sides of the tree, especially the shaded portions seem to be developing bloom now. There is still plenty of time for bloom to occur. In some years remember, it is February before we get full bloom.....or in some cases, second or third bloom if earlier bloom doesn't set any fruit for whatever reasons.
