We are not currently accepting worm tea orders due to COVID-19
The Department of Public Worms is now offering worm tea to the local gardening community! Our tea invigorates your plants by providing high amounts of nutrients and organic content to your soil. Best of all, our worm tea is made onsite at UCSB with worm castings produced from locally collected food scraps from our campus.
Worm Tea – What is it? It’s not for drinking!
Worm tea is a natural, non-synthetic liquid soil amendment (also known as a fertilizer) made by steeping worm castings in oxygenated water. Oxygenating worm tea helps grow beneficial microbes that enrich soil. Because worm tea contains living microbes we recommend storing it in the refrigerator, where it can last up to 3 days before the microbe populations begin to decline, but it is best to use as soon as possible. Worm tea also contains water-soluble nutrients such as nitrates, phosphorous, magnesium, potassium, and calcium in addition to many nitrogen fixing microbes.
Worm Tea is NOT for human consumption!

How to Use
Worm tea does not need to be diluted since it is great as is! Diluting worm tea is possible, however, if you would like it to stretch further for your garden. When diluting, make sure to always dilute with non chlorinated water by using a dechlorintor or by letting tap water sit in a bucket for 24 hours.
You can pour worm tea into your soil for added nutrients or spray onto leaves (not in direct sun) to help detract pests and keep plants strong.
Not advised for use if mold or film develops on top of the liquid, or if the liquid becomes overly cloudy. While uncommon, these are signs of rot and the worm tea should be disposed. Worm Tea doesn’t technically expire, but it is best to use it while it’s fresh for the most microbes and the highest quality nutrients.

Does DPW Sell Worm Castings?
We are currently not selling worm castings as we simply cannot produce enough to meet demand for both castings and tea. Our tea is more popular and a much more versatile product with a faster effect, so check it out!
Does DPW Sell Red Wriggler Worms?
Unfortunately we do not sell worms because previous worm sales led to a population crash in our worm bins. In order to continue to compost at UCSB and to continue to provide worm tea, we are unable to distribute worms.
