Trees planted in a swale bank (I copied a drawing)

This is my favorite drawing of a swale:

I thought it was from the PDM but it's not. Maybe Intro To Permaculture?
Anyway, I posted this a few days ago and it occurred to me I had actually done this!

This year I planted some fruit trees on a small swale, and, well, here's the pic:


OK, it's the cold temperate version, but pretty darn close! Hard to see the individual plants but they are there. The main thing I'm missing is the fast growing leguminous tree. I do have a few honey locust and black locust in peat pots on a window sill, but I wonder if I need to add them. The soil's pretty good and it's downslope from the sheep area. Lots of Stinging Nettle so I think the fertility is good.

All the sticks were to keep the chickens from digging the seedlings and it worked. The only problem now is the 137 lb dog likes to lay down in the bare ground to the right of the sticks and that's where the asparagus is trying to come up.

I'm not sure what the temperature version of Taro (water plant) would be. I could always add it next year. Suggestions?

Here it is from the front:

Nice. So my question is did you plant them all at once or did you wait a bit for the tree to establish first? I have 32 fruit and nut trees coming and I've been considering my swale planting. I actually thought I'd paper around them to keep weeds coming up. Not sure now.

All at once except for the last 2 trees which went in after the swale was planted.

Thanks!
