High Five

Difficulty: Medium-hard

High Five is an achievement in Plants vs. Zombies 2: It's About Time. It requires the player to plant five Tall-nuts and use Plant Food on all of them. It is worth 10 points on Game Center for iOS devices and 1,000 XP on Android devices.

Strategies
As this requires the use of five Plant Food to complete, some planning is required on the part of the player. Longer levels with more flags (and thus more zombies dropping Plant Food) are the best times to attempt this achievement. Do not try obtaining this level in Last Stand because the zombies do not drop Plant Food and the Plant Food given is never enough. It is not impossible, but it requires to spend at least 1000 coins on extra Plant Food (if playing Far Future - Day 22 with the Plant Food Boost).

Another level to do this on is Wild West - Day 25. The amount of Plant Food that can be obtained there easily exceeds five and Tall-nuts are obtained for free at a possibly common rate. However, Tall-nuts can easily be eaten by zombies or destroyed by missiles, so it is not necessarily easy.

As of Far Future, you can spend 12 gems or use the boost for the Tall-nut from the Zen Garden. Therefore, you can just use the boost and plant five Tall-nuts. By spending a large amount of sun, you can also plant five Tile Turnips, put Tall-nuts on the Power Tiles, and then use only one Plant Food. However, doing so, you need to spend 3750 sun on Tile Turnips, plus the cost of five Tall-nuts which is 625 sun, for a total of 4375 sun. Instead, planting Tall-nuts on Power Tiles will help you reducing the sun cost, as well as the Plant Food usage.

An easy way to get this is to have a boosted Tall-nut on any level. Use Plant Food to recharge the Tall-nut seed packet and keep placing them if you have the instant recharge upgrade.
