Lots of people are using it on orchids! WORM TEA is collected by the spraying of the worm pits. The worm urine as well as the other nutrients are combined and recycled. See http://www.ourvitalearth.com/worm-tea.htm for more details. Another of the orchid forums has MANY users (as well as myself). Other than the natural fertilizer benefit another great benefit is its pesticide value. Try it - you'll like it! mike

Yuck!!

I avoid feeding my orchids nitrogen derived from urea.
I much prefer fish emulsion.

Jane, it only 'sounds' yucky! No odor that I've noticed. Becuase of the expense I'm using it only on my paphs and a few of my phrags, also a lycaste. Also the sickies/rootless guys get the worm tea. Too soon to tell if it's really better then other plant foods. Jerry Meola has more info on his website.

worm tea is not good on orchids because of the worm urine.

I have been using worm tea on my chids' for a month or so and they have never looked better! I will soak them in a bucket of water and worm tea for a few minutes once a week, and I will also mix it in w/ my misting bottle. Living in S FL and growing vandas outside on my trees it has been a real challenge keeping my roots from cracking. I would water my vandas 5 times a day sometimes and still could not keep the roots from cracking. Then I began giving them the soak treatment with the tea mix and it has helped my problem. Not completely, but way better than before and I am still experimenting. It is a little pricey but I am still on my first bottle and it seems to go pretty far, but if you invest in a worm bin then you can have an unlimited supply.

Like granniek said Jerry Meola's site can tell you a lot about the subject.

Toyo, I found that fish emulsion burns roots. I much prefer liquid seaweed, or the worm tea.

I do think the worm tea can be too powerful for some orchids, so I use it more sparingly than most people. I only use it once a month.

Interesting. I see the no no no never urea thing has surfaced again.

Anyway, here from a local orchid orchid society bulletin is a recipe as used by one of the local growers.

Is it any good? Cannot say. except that the recipe providor exhibits nicely grown plants at monthly meetings and shows.

Good General Fertilizer Mix.
1 Teaspoon of CampbellÂs Yellow or HSO 12 12 20
Quarter Teaspoon of Epsom salts
60 ml of Seaweed (Seasol)
20 ml of Fish Emulsion (Charlie Carp)
1 Teaspoon of Sugar (white)
60 ml of worm juice
Add to 8 litres of water.
= 500 ppm or 1EC.

Sorry about the metric, can unscramble length and temps, but can only think metric for some things.
