Since most native languages do not contain articles/determiners, people often miss using them. It is necessary to note that all noun phrases except those, which begin usually with a proper noun, take an article/determiner.
For example, rather than saying
'Flowers in my garden are in bloom'
say 'The flowers in my garden are in bloom'.
