A cheap sump pump (one that can handle water with gunk in it) with a hose attached--just pump it out via the hose to each plant. Much, much easier on the back.

Even easier: just put the alfalfa around the roses and skip the tea part.

I was thinking of putting it around my roses but I was afraid that it would attract the rabbits.

Rabbits like fresh juicy stuff, not dried up ground stuff.
They don't touch it here.

Best way to find out is to try--try a few with just the meal, and the others with the tea, and see what your results are. I think tea is quicker, but not much quicker. Make sure your pump can handle solids lest you damage or break it. Some pumps are built to, while others are not.

What you want is a trash pump. They're often placed into large ponds to supply irrigation water. They're similar in appearance to a sump pump but have stronger and sharper blades that can handle solids. I have one for the lower level bathroom sump that ejects the waste into my septic system.
Or, you could build a set up such as this and let gravity and a garden hose work for you.

I cut an opening in the tops so I could lower mesh bags full of alfalfa meal into the water.
One note,
Use the meal form if you apply it directly to the soil as rabbits will eat the pellets which often use molasses as a binder. If you do use the pellets pour them into holes in the soil and cover them up. You can make holes with a spading fork or dibble.
My drums are syrup drums from a bottling plant. The plugs are threaded so a hose bib will screw directly into them.
