Yes it is a good idea to fertilize at least a couple times per year. You can read on most bags what they suggest as a schedule. You may need to change by season as rain will wash many nutrients away. If you want to garden year round, then you can use lawn fertilizer year round. Consult a gardening store or website to see information on what type of fertilizer to use, because this depends on what the grass blade looks like.
