My tomatoes literally doubled in size after switching to Elm Dirt. The transformation was so dramatic that I started posting before-and-after photos on my gardening Instagram.

Living in Florida with sandy soil is brutal for plants. When mine start looking sad, I give them plant juice and literally overnight they perk back up. It's my go-to plant rescue.

Questions? We've Got Answers

Everything you need to know about making the switch to premium organic plant nutrition.

Absolutely. We're talking 100% organic ingredients here—no synthetic chemicals, no scary additives. Your toddler could eat treated soil and be fine (though we don't recommend it as a snack). We created these products with the same safety standards we'd want for our own families. Learn more about the science behind organic plant care safety and see why thousands of families trust our products.
For our liquid fertilizers like Plant Juice, once a week during growing season works great. Think of it like a weekly multivitamin for your plants. Soil amendments like worm castings can be applied every 4-6 weeks. The beauty of organic nutrition is that it's very forgiving. Check out our detailed houseplant feeding schedule for specific timing.
This is actually where organic fertilizer really shines. Your tomatoes, peppers, herbs—they'll love it. And here's the bonus: organic nutrition often makes vegetables taste better and more nutritious. Our Hi-Energy Fish fertilizer is especially popular with vegetable gardeners. Get the complete guide to vegetable garden success or learn about growing amazing tomatoes.
Those synthetic fertilizers are like feeding your plants energy drinks—quick boost, but terrible long-term effects. They can burn plants, kill beneficial soil microbes, and actually make your soil worse over time. Our organic plant food builds healthier soil that gets better every season. Read about why organic fertilizers work better and discover the connection between soil health and human health.
Great question! Our Houseplant Bundle is perfect for indoor plants, while our Gardener's Gift bundle gives you everything needed for outdoor gardens. Both include Plant Juice plus soil amendments to get you started right. Check out our complete bundle comparison guide to find your perfect match.
Yellow leaves are often a sign of nutrient deficiency or poor soil health—exactly what organic fertilizers excel at fixing. Unlike synthetic fertilizers that provide a quick fix, our products rebuild the soil ecosystem so plants can access nutrients naturally. Start with Plant Juice for immediate nutrition, then add worm castings for long-term soil health. Our plant troubleshooting guide has more solutions for common problems.
