Hey everyone! I'm setting up two big raised beds in the Pacific Northwest (zone 8b), and I accidentally ordered the wrong soil mix. I meant to get a raised bed mix which has 1 part manure and 1 part a 4-way mix (sand, loam, compost, and manure). But I ended up just getting the 4-way mix. Do you think this will work for my raised beds? Should I add in some compost or manure to balance it out? I'm mainly looking to grow potatoes. Any advice would be greatly appreciated!

Honestly, the 4-way mix might be okay, but you should consider that raised bed mixes typically have a lot of organic materials which can lead to compaction over time. I’d suggest mixing in a sandy loam with about 10-15% compost rather than a lot of manure. Also, adding a layer of compost on top can help with nutrients and structure. It's about getting that right balance for better soil stability.
You're probably good to go with that mix! Just make sure to toss in some organic fertilizer since potatoes are pretty heavy feeders. Giving your plants a proper start can really help them thrive. Good luck with your growing!
Either soil mix should work fine since both seem similar in ingredients. Potatoes are pretty resilient; I've even pulled out big ones from my compost pile, which had a mix of garden waste and leftover soil! So, don't stress too much about it—your potatoes should do well.

That’s true! Potatoes can flourish in various situations, even in less-than-ideal conditions. They’re definitely the hardiest of crops.
