However, because the collection time is too early, it's difficult to put it out on garbage day.
Literal
However, collection time [subject-が] too-early [because-ため], garbage [of-の] day [on-に] put-out thing [subject-が] difficult [copula-です].
~すぎる attached to an adjective gives 'too X' (早い + すぎる = 早すぎる 'too early'). ~ため is a reason/cause marker, slightly more formal than ~から or ~ので — common in written explanations. ゴミの日 'garbage day' is part of the tightly scheduled Japanese residential garbage collection system where different categories (燃えるゴミ, 資源ゴミ, etc.) are picked up on specific fixed days. 出す 'put out' has a specialized sense here for placing trash at the collection point.
