Warm, specific, and done before dinner.

You already know the words — mycorrhizae, compost tea, humus. You don’t need them defined. You need a recipe for the bed you’re standing in.

 

Tomatoes

1. At planting: a generous handful (about a cup) in the hole. Mix with the native soil so roots meet life, not a clump.
2. When the first fruit sets: a light ring of castings around the stem, scratched in and watered.
3. You cannot burn a tomato with this. If you’re nervous, that’s the synthetic talking.

Raised beds

1. Established beds: a quarter-inch top-dress in spring. Rake it in. Water.
2. New beds: mix about 10% by volume into the top 8–10 inches. This is the “build it once” rate.
3. Mid-season, if leaves fade: another thin dusting beats a liquid salt every time.

Houseplants

1. A tablespoon or two on the surface, once a month. Water it in.
2. When you repot: 10% mixed into the new soil.
3. Yellow leaves on a plant you’ve babied for two years is often tired soil, not a lighting problem.

Seed starting

1. Blend 10% castings into your starter mix. Fine, screened material only — that’s what we bag.
2. Don’t fill a cell with pure castings. Seedlings want air as much as biology.
3. A pinch in the transplant hole when they go outside is the handoff.

Casting tea, if you like a project

One cup of castings in a gallon of dechlorinated water. Steep 12–24 hours, stir once. Water the soil, not the leaves, in the evening. This is a microbial drink, not a concentrate you should fear. Use it the day you brew it.
