I've got all sorts of gardening setups — raised beds, pots, and containers filled with potting soil, avoiding the native caliche. I've tried adjusting water levels, experimenting with compost and fertilizers, and even made changes for better sunlight by cutting down trees. I've also tested and amended the soil according to every guide I can find. Still, nothing thrives! My seedlings germinate but never grow past small, two-leaf stages. I've attempted various crops including tomatoes, squash, beans, and herbs, in addition to flowers, but no luck. Despite using grow lights and heat mats, I've spent a lot of money to see zero results! I'm starting to think that gardening in southern Arizona is only for seasoned pros. I really need advice on what might be going wrong or any suggestions on what to try next. I'm at my wit's end here!

Have you checked for proper soil aeration? Seedlings need oxygen, and if your soil is too dense, their roots can suffocate. You might want to mix in materials like perlite or pumice to improve the soil structure. Also, remember that different plants have different temperature needs—peppers usually prefer warmer temps while others like onions can thrive in cooler conditions. Just a thought!
It sounds like your seedlings might be struggling due to root or soil-level issues. A lot of times, seedlings fail to thrive because they can't establish a strong root system. I'd recommend posting some pictures of your setup and soil—sometimes it can help identify the problem better. Good luck!
It's crucial to know how you're testing your soil. Have you used a professional testing service, or just home kits? A local extension office can provide detailed soil analysis, which might reveal issues you're missing. I learned the hard way that home tests can be misleading; mine showed fine readings but a pro test revealed imbalances and high pH levels. Getting that tested could be a game-changer for you!
I only did home tests, but I will definitely look into getting a professional test done. Thanks for the suggestion!
