I've never tried to use them like that.
Being a legume, it's probably all that nitrgen.
Planting a winter crop of it, or any other legume, and tilling it in will do wonders for your garden.
You could also try the alfalfa cubes and see how they hold up. Could be interesting.
I know that a lot of rose growers use them or the tea.

You are aware, I hope, that is the best that they'll ever smell.
You should try using them after they've been "processed"! ;~)
Lets see...
The sheep could make it for my seedlings and Plueros.
The horses for Catts and Bulbos.(People already do for some things!)
The cows...?
It's just fine where it is! ;~)

Although the pellets smell different, I love the smell of alfalfa.
Especially in the morning...or is that napalm!
I always get them mixed up! ;~)

Alfalfa meal/tea/pellets are a wonderful supplement for any plant since the tricontanol acts like a steroid. I broadcast it over all my perennial beds and add a handful (or two) to each potted tomato plant. I believe the initial studies were done on soybean fields to increase the yield and have since spread to other food crops and ornamental plants.

From an organic gardenign website"Alfalfa Meal 2-0-2

Contains tricontanol, a known plant growth stimulant, while also containing nitrogen, phosphorous, potassium, calcium, magnesium plus many other trace elements, sugars, protein, and co-enzymes. When soaked in water, makes an excellent "tea" for all plants, especially roses."

I've made a fermented compost tea out of the big alfalfa pellets that farm/garden stores sell as horse 'treats.' I must say, it has a really hellish aroma. Supposedly, though, this brew is an effective foliar spray or soil drench for everything from virus and bacteria to nematode and aphid.
The smell, even diluted, will make you think your eyelids are bleeding!

Hello.
What are the amounts of alfalfa and bark you mix for cattleyas?
Thanks.
Lupita.

I would be concerned about it breaking down into mush and holding a lot of water. I have made alfalfa tea before and it doesn't long for the pellets to break down. I personally would do it for terrestrials but not for much else.

Nancy how do you use alfalfa brew against nematodes? At what concentration I mean...
