Stardew Valley: How to Earn Money Faster

Foraging at the end of the day is a super-easy way to make money. Sure, they don’t tell for a LOT (like farming) but they do help your skill points.
You should choose the mushroom option when Demetrius comes to your farm and asks what you would prefer. The mushrooms spawn every other day, so you get more profit quicker which also helps your foraging skill.
At the end of the day if you still have a bit of energy left, you should walk around to the top right area above your farm, and into the secret woods to forage (also near the sewage area) because many foraging items spawn here.
Mixed seeds ALSO help foraging skills, however, you shouldn’t waste any bit of money on mixed seeds because the profit isn’t worth it.

By far, blueberries and cranberries are one of the best crops to buy in the game. You only need to purchase them once all season, and they continue to grow. And most of all, they sell for a GREAT price making it super useful and totally worth it. They can get a little pricey, so before summer and spring make sure to have done fishing in winter to earn some cash to purchase them beforehand.
They are one of the best investments you can make, even if you use all of your cash to buy a few of them.

With this, I recommend choosing a skill point that allows there to have a chance of crop-producing multiple drops of that crop. This will earn you even more.

Now, fishing is one of the QUICKEST money makers. If you didn’t know, you can actually sell the fish you earn to Willy (before 5PM) once you catch them. When selling your fish to him, it gives the same amount of cash it would if you use the box at your farm, however it’s just faster. Initially, I didn’t know this and when I needed to purchase something right away, I couldn’t. And by the time I realized his shop was already closed. This will help you if you need to buy seeds before the season ends for the greenhouse (if you have that in the game yet).
