We have had a few questions recently about the proper use of worm tea (the tea made from worm castings or worm poop) in the garden, so we wanted to give some pointers to clear up a few misconceptions. The most important thing to remember about using worm tea in the urban garden is that the longer you wait before using it, the less effective it will be. The beneficial microbes contained in the worm tea begin dying off quickly, so you don’t want to put of its use for too long. Here are a few other tips on using worm tea in the garden:
- For the garden, use worm tea full strength no more than once per week.
- For houseplants, use worm tea full strength once per month during the normal watering schedule.
- For the lawn, use worm tea 50/50 strength diluted in water and distributed in a sprayer.
- As a foliar spray, use full strength or diluted according to preference. Apply late in the evening.
- Don’t overdo it. Worm tea is full of good stuff. Beneficial stuff. But too much of a good thing can be harmful to your plants and even kill them in some cases. I recommend using worm tea in the garden no more often than once per week.
Regardless of how you choose to use your worm tea, your plants will thank you. Most plants show visible signs of improved health and growth within just one or two applications and your garden will probably be no exception to that.
Do you have any experience with worm tea in the garden?
