Not all native English speakers write well. When reading articles written by non-native speakers I can often work out their primary language from the idioms that they translate into English. You don't mention what level of articles you are asking about. If you are writing articles for top level academic journals, then engaging the services of an editor or having an competent English writer as collaborator is a very good idea. In a more informal setting you could always enlist the help of people interested in your topics to review your writings before publishing them more widely.
