Beginner Gardening: Crisped Strawberry Leaves, 1 by JessJess

I have two strawberry plants growing in a corner of the yard at work. Before planting, I amended our sandy loam with compost, steer manure, and some garden soil.

The strawberry on the north side of the bed (first picture) seems to be burning. The edges of the leaves are browning. The strawberry on the south side of the bed (second picture) doesn't appear to be having that issue, but neither is it really thriving. I blame our incredibly poor soil. These will only last through the season (until we get a nice hard frost) but I'd like them to look healthy until then.

Is it just getting too much sun? I don't think it's a problem of too-little nutrients because the leaves look nice and healthy when they emerge, they just... get crispy. I don't know if something's munching on them, or if I need to find a way to... stick a parasol in the yard to help mitigate the sun?

What do you guys think?
