I recently filled my raised garden beds with a mix that includes topsoil, black kow, peat moss, some potting soil, earthworm castings, and perlite in roughly a 45:45:10 ratio. After watering it down, the top layer became muddy while the soil below didn't seem to absorb the moisture at all. I did water in between adding the soil, but I'm worried I might not have done it thoroughly enough. Will the lower soil eventually become damp on its own, or do I need to take some steps to fix this issue?

Consider avoiding peat moss in the future as it's not the best for sustainability. I switched to using Coco-Loco from Fox Farm for my seedlings, but it can be pricey. For the raised beds, I recommend trying a local soil mix made from compost and ground pine fines. They hold moisture better and are more environmentally friendly!
It sounds like you might have a bit of a hydrophobic situation with your peat moss. Make sure to really soak it down instead of just a light watering. Also, try deep watering by digging some holes with a fork or shovel to help the water penetrate better. Giving it a good, deep soak for a few minutes each day should help!
You could benefit from mixing in more aerating materials to help with drainage. Things like vermiculite or perlite are great options. They allow air and water to move through better. I also use clay balls sometimes!
Yeah, just make sure to water deeply for a while! It’s the best way to ensure the lower layers get moist.
