Watering dirt and dead things

Even though it's no longer suicidal squirrel weather, we're technically still in a drought.  So once a week I've been lugging the garden hose out to the fruit trees.

I'm sure that I've mentioned before that my most un-favorite gardening chore is watering.  I prefer weeding to watering.  So you can imagine my lack of enthusiasm at having to water a bunch of "dead"  (i.e. leafless) fruit trees.

Since I had the mile and a half of hose out anyhow, I figured I may as well water the dirt.  Yes, there are dormant tulip, lily and iris bulbs underneath that dirt, but the more primitive part of my brain still can't get over why I'm wasting time watering dirt.  I then walked over to the garden to water a bunch of chicken and goat crap; the compost heap.

I did end my hose-dragging trip across the county by watering the carrots/peas/beets in the raised hoop house bed though.

By the looks of the weeds, you'd think that weeding, not watering,
was my least favorite gardening chore.

At least I got to water something green and alive.  I keep meaning to rip out the freeze-killed tomato plants in the other raised bed and plant something, but I haven't got around to that yet; it looks pathetic.  The plastic cover on the other bed has kept the vegetable plants from freezing, but they've only had to deal with a handful of days in the low 30's or upper 20's at night and they are still looking well.  The past few days have been in the upper 60's and today and tomorrow we're supposed to be flirting with 75 degrees so I'm taking the plastic off and letting them get some fresh air.

Question for my gardening friends:  I know that the root crops and lettuce don't need a pollinator to yield, but what about my peas?  I didn't even think of it until I started covering them up at night.  They are doing pretty well, but there are no flowers on them.  And even if there were flowers on them, there isn't much of anything buzzing around now to pollinate them.  Will they even bother growing flowers?  And if they do, will I have to hand-pollinate them to get peas?
