Always Upgrade Tools

Make sure you upgrade your tools whenever possible. Basically, better tools means an easier time working your farm as upgrades can make them work faster and more efficently and even enable them to hit special items lower level tools cannot. You can upgrade your tools at the Blacksmith in exchange for gold and metal bars. Upgrading your tools takes two days to complete and during the upgrade you will not be able to purchase anything. Tools must be upgraded in ascending order of materials.

If you take your watering can to be upgraded during the middle of summer there will be two days where you will not be able to water your crops which means during that time they will not grow. The best time to upgrade your watering can is on the last day of fall as you don’t need to water the crops on the last day when you are harvesting them, and in winter as there are no crops to water in winter.
