I've been looking for advice on the best NPK ratio to use for spinach because I've seen varying recommendations online. I'm planning to buy fertilizer soon, not only for my spinach but also for my other plants like Roma tomatoes, pasilla peppers, and jalapeños. Right now, I'm focusing on the spinach, so I want to make sure I'm giving it the right nutrients first before I tackle the fertilizer for my other veggies.

For spinach, you generally want a fertilizer that's higher in nitrogen since it focuses on leaf growth. A good starting ratio would be something like 3-3-3, feeding at quarter strength initially. As your other plants (like tomatoes and peppers) start to fruit, you can switch to a higher PK ratio like 2-6-4. Another option for spinach could be around 4-2-2 for steady growth. Just remember, different plants have different needs!
Thanks for the insight! I was also confused by some suggestions I saw online; someone mentioned 5-2-2 might work for spinach, but it seemed a bit too low based on what I've read. I'll definitely consider your advice!
