Tap what you're growing. We'll tell you exactly how much worm poop to deploy. (It's a technical term.)
🏠 Houseplants
Mix 1 part castings to 3 parts potting mix, or top-dress ½ inch and water in.
💡 Your fiddle-leaf fig has trust issues. Castings won't burn it, so start small and watch it forgive you.
🥕 Veggie Garden
Side-dress 1–2 inches around plants, or mix a handful into each transplant hole.
💡 Tomatoes are heavy feeders with zero shame. Give them the good stuff at planting time.
🌱 Seedlings
Mix 10–20% castings into seed-starting mix. Gentle enough not to burn babies.
💡 Seedlings are like newborns: tiny, dramatic, and sensitive. Castings are the gentle grandparent of fertilizers.
🌳 Trees & Shrubs
Spread 2–3 inches under the drip line, mulch over top.
💡 The drip line is where the rain falls off the leaves — and where the feeder roots are waiting with tiny forks and knives.
🌱 Lawn
Top-dress ¼ inch and water in. Your grass will thank you.
💡 A quarter inch doesn't look like much. That's the point — the microbes do the heavy lifting underground.
When in doubt, less is more to start. You can always add more castings — you can't un-add them. (Well, you could, but it'd be weird.)
