We're worm composting. My plants do seem to love it! But on my roses I mostly use composted horse manure, they seem happy enough with that. I use the worm compost on my house plants, (it doesn't smell bad!) and on flowers and vegetables that like an extra boost.

I apply 1-2 cups of used coffee grounds
under and around each rose bush and scratch the used grounds into the soil a bit. I do this in Mid April or later and only 1 time a season.
I also use a 1/2" layer of well composted cow/horse manure.
And alittle organic type granular fertilizer, 1/2 to 1 cup.
2" layer of wood mulch.

This causes an explosion in earthworm population here in our soil.
This is keeping our soil loosened and earthworms will secrete there wastes into the soil, etc, etc.

I was just up there the other day looking under the mulch and even with colder weather, there is still a lot of worms near the surface of the soil.

I'm not familar with red wiggler soil waste compost.
But, I think I'll research this subject and learn more.
It sounds very interesting canadian_rose!
Let us know how you make out in the future.

Jim - I will warn you :) that fruit flies like the red wiggler bin. So I take it outside to open the box up. Then bring it back in when I'm finished adding food.

Most sites say that you need holes in the bin (top and bottom). I don't do that, and my worms are just fine. I have a 5 X 2 foot plastic bin.

rozgardener - glad it works. Does your bin get fruit flies?

I don't worry about worms in the ground, since my roses are in pots. :)

I have 5 worm bins, and yes, my roses get their portion of the vermicompost. It's good stuff.

You won't get fruit flies if you bury the food waste you put in there. Fruit flies don't burrow, they'll only go for what's "above ground."

I bury and still have fruit flies, guess my bugs forgot to read the book >:-(
