there is no such thing as sandbox. only that age of site is a SEO factor. work on content and backlinks for better ranking.
I suggest you focus more on the keywords that is not doing good on SERPs. Use the keywords as anchor text and you can put the keyword/s in the title of your contents. Focus on adding new and fresh articles and blogs. You may also do on page optimization.
I highly doubt that there is a sandbox. However you should focus on getting high quality links and writing valuable content.
