Tomatillos seem to be one of those easy fruits. They do require plenty of water. All the ones I planted in the beds along the house did great and are loaded with fruit. Other years when we’ve had more rain the fruit were even larger.
There are also several plants up along the driveway that the chickens planted and Will staked to protect and support them. The poultry planted tomatillo plants are dwarfed and their fruit are smaller and fewer. Even where they had good nutrients, the lack of water stunted the plants in contrast to the ones that thrived in the run off from the old farm house roof.
