Throw your plants a compost tea party this spring! Compost tea can be applied as a foliar or soil drench. It is easy to make with just a few components and can be customized to your plants' needs. Compost tea takes all the goodness from your compost and makes it even better. We have a great video showing you step-by-step on how to make it. There are so many versions of compost tea recipes but you can “brew” your own version. The basic components of compost tea includes water, compost (or you can use arctic humus or worm castings) and a tea catalyst. Additions can be made to your tea–liquid kelp or maxicrop (a kelp extract), or liquid fish are great to supplements your compost tea. You can customize your brew according to the stage of growth your plants are in (growing, blooming or fruiting). The additions can be added at the end of the brewing process. You can apply the tea using a watering can or sprayer (clean).If foliar feeding, dilute the tea to one part tea to 10 parts water (dechlorinated water). Or if applying to the soil, dilute one part tea to 5 parts water (dechlorinated water).
