Kale is the big rage and buying organic kale in the grocery stores can get PRICY! Grow your own! It’s one of the easiest plants to grow and you can have kale for years to come from one plant.  Kale is one of the few plants that you can harvest all year long, even in the winter months.  If you use something called a hugelkultur setup, you can even keep producing and harvesting in the snow!  There are multiple seed varieties to suit whatever your need is.  If you’re wanting a dwarf plant that doesn’t get too tall, it exists!  If you want one for your cold winter months, it exists!  If you’re wanting a kale tree, it exists!  The options are huge and it would take a lifetime to go through them all!

For the hydroponics and aquaponics growers out there.  Kale is one of the few plants we have a crazy amount of success within any of our systems.  Kale loves the raft system that keeps the roots in constant contact with water.  Or grow successfully in a media bed flood and drain system.

Kale is also incredible for eating.  Packed with antioxidants and useful in many dishes.  Have it in a green smoothie, have it in a salad, or sautee it!  We love kale so much that it’s a common staple for our household!
