If you planted them in a ‘V’ and filled it in, they should be fine. You’ll see that once established they’re basically a weed. Granted, a DELICIOUS weed, but still a weed, LOL!
I have 6 shoots up so far. One of the dogs broke one off running through there, so I ate it. :)
I mulch lightly in the summer months, and then after I trim off the dead fronds, I put a good 6” of straw on top to get them through the winter - but it’s much colder up here than down by you, so you may not need as much winter protection.
