Item
Garden is an in-game item that can be bought from a Shop or can be found in a Crate. Most Items modify the Stats of the player, and some of them provide additional effects.
Garden
The Garden item spawns a small garden at the start of each wave for each Garden item you have. Each garden drop consumables as soon as they spawn, and then continuedly spawns fruits throughout the wave with a 15 secound cooldown.
The Pruner weapon also spawns gardens that produce fruits with a 15/14/12/10 second cooldown.
Gardens are Structures, so they benefit from Improved Tools and
Clockwork Wasp, reducing the cooldown of fruits spawning and it grants +2 Armor per garden to
Streamer.
The healing of the fruits can be increased by Lemonade or
Weird Food and can grant Max HP if you have the
Extra Stomach item. Or extra harvesting for the
Farmer and Explosive Damage with
Glutton.
