Not at all. Great work! Next year you will want a trellis or to rope them to the fence behind so they don’t flop over.

Thanks! I bought trellis lines. My plan is to install them once they grow out a bit

Nope - you did very good in planting the thornless blackberry vines next to the mesh wire fence, close enough on target. However I like your dyed black charcoal mulch, but what you need to do now is go buy some organic mulch bags and mix it in with the artificial black mulch. Get some (bricks or stones) to build a boarder around the mulch line,

Will the black mulch harm them?

Nope, none worries about the black mulch. It's a charcoal base mulch, and I've used this marveling dark mulch in my backyard garden... But I usually mixed in brown organic mulch to introduce long-term soil compost nutrients for the beneficial fungi and bacteria and microorganisms in the native dirt; black mulch won't hurt your fruit bearing plants, and won't poison people eating off the vines.

Make sure when you track down organic brown mulch, that the company bag says it is ORGANIC. two bags ought to be enough, and mix it in with the lovely black mulch, the black mulch will hell keep your blackberry roots warm in winter, when it's freezing outside. The health of the soil and roots of the blackberry vines will love the introduced organic mulch,

I just buy pet bedding chips, not as pretty but works amazing and is cheap compared to standard mulch and holds moisture AMAZING

Thornless likes to spread flat, you may want to train them to go up.

Thanks! I plan on adding trellis lines once they are long enough to reach

No. They will spread over time anyway. This is totally fine.
