The garden in the back of the grounds needs work.

I agree with Gringo except to say "El jardín necesita trabajo." This would indicate that the gardin is looking for a job.
Mantenerse / arreglarse / atenderse would be more fitting.
We all need to think more openly and less literally when forming thoughts in Spanish.
For example: The garden needs work. The garden behind the house need work. The back garden needs work. All of these convey approximately the same idea. Yet some are easier than other to communicate in Spanish.
In Spanish "grounds" would most likely be communicated with the words "tierra" or 'terreno". I would use terreno. But in this case I would simplify and just say.
El jardín (atras la casa) necesita trabajo.
Try the "Translate" link at the top of the page. The idea might translate better if you use "He needs (we, you or they need) to work on the garden.in the back of the property." Although your wording in English is perfectly acceptable, the translator will translate, not interpret the idea. Technically ii is all translation when you are referring to the written word. Interpretation refers to the spoken word. You might not want to make the garden the subject (who does the action of the verb) of the Spanish sentence.
