Berries are a useful item that you can use with your Pokémon during battle or throw them into your curry, which is new to Pokémon Sword and Shield. You can find them everywhere, but you frequently encounter them in bays. These tall trees have a variety of colorful orbs attached to their branches. When you approach them, you can start shaking the tree to acquire them and add more to your collection.
You have a few methods to grow these berries. The easiest technique is to use the Rotom bike, which you receive naturally as you progress through the game's story. When you get it, use it in the Wild Area just outside of Hammerlocke and Motostroke to find several of these berries. Approach them, shake them, grab the respective berries, then move on to the next one.
Using the Rotom bike, you can zip around the area to grab them all. Berries do not respawn when walking from region to region. So you want to cycle around the entire wilderness area and then return to your starting point.
You receive rarer berries in harder to reach places in the Wild Area, such as Azew's Eye and Lake of Outrage. You can only access these locations by acquiring the Rotom Bicycle upgrade to cross water. When you have access to them, you should frequent these two places during your rotation and have access to a wider variety of premium berries. You will know that you have the rarest of them by reading the information contained in the description of the berry, which you can read at any time from the "berries" section located in your bag.
You will not receive the same amount of berries from each tree. When you approach the tree and start shaking it, a handful of berries fall. If you keep shaking the tree, you increase the chance of a Pokémon falling from it. They land on your head and you fight for them. When it's over, a good majority of berries are picked up by other Pokemon while you were distracted.
To prevent Pokémon from falling, you must watch how the tree shakes before attempting it again. If the branches of the tree are shaking violently at a rapid pace, chances are one of them will fall. If it's distinct enough, like every two or three seconds, you should keep shaking the tree and try to get more berries.
Another alternative to catching berries is to complete Max Raids and battle Dynamex Pokémon in their dens. However, this is not always guaranteed, and sometimes you have two or three to finish a battle. These engagements can be time consuming and are much longer than just navigating from tree to tree. But if you're working in The Dens, it's worth noting that harder Dynamax battles give you access to better berries.
Be sure to visit the merchants in the Wild Area who wear green and red with a large backpack. Talk to them and they have a whole range of curry items you want to throw in before throwing your fruit into your meals. Creating the best curry takes a reasonable amount of time, and there are several techniques to approach the highest rank. The use of rare berries is also essential.
