The lodge’s garden is mostly in fabric pots and barrels on a high, windy ridge, and it is fed almost entirely with living teas: water, worm castings and a little sugar, aerated for a day until the microbes in them multiply by the billions. No synthetic fertiliser, no pesticides. This chapter is the practice as it stands.
Why fabric pots
- They breathe. Roots that reach the felt wall meet air and stop, then branch. That is called air pruning, and it gives a dense, fibrous root ball instead of roots circling the inside of a plastic pot.
- They drain completely. Waterlogged soil goes anaerobic, sour-smelling, within days. Felt cannot hold standing water.
- Rescue for drowned soil: spread it thin on a tarp in full sun for a few hours, then re-pot into felt.
The three teas
| Tea | Cadence | Goes to | Made from |
|---|---|---|---|
| 1. Root drench | every 14 days | soil, all plants | castings, kelp, bone meal, coffee grounds, molasses; mycorrhizal fungi stirred in at pouring |
| 2. Foliar spray | every 5 days | leaves, all plants | the same brew, strained fine |
| 3. Nitrogen boost | monthly | soil, heavy feeders only (corn, cabbage) | blood meal added to the brew |
The base brew for a 5-gallon bucket: about 2 cups of moist worm castings and 1.5 to 2 tablespoons of unsulfured blackstrap molasses in 4.5 gallons of water, aerated hard for 24 hours.
The rules that keep it alive
- Unsulfured molasses only. Sulfur is a preservative; it kills the microbes you are trying to grow.
- No chlorine. Well water and rainwater can go straight in. City water needs a couple of hours of bubbling first to drive off chlorine.
- Warm it. Microbes multiply best between about 68 and 80 F. Cold well water straight from the ground runs 50 to 55 F, so warm it with an aquarium heater before adding anything. A felt wrap around the bucket holds roughly ten degrees on a cool night.
- Aerate hard. A real air pump (25 litres a minute or more) and two heavy stones on the bucket floor, with check valves on the lines. A small aquarium stone will not do it.
- Never seal the bucket. Cover it loosely. Aerobic brews need gas exchange.
- A good brew froths. A creamy foam head after 18 to 24 hours means it is alive. No foam: check chlorine, temperature, airflow and the molasses, in that order.
- Use it within hours. Once the air stops, the brew starts going anaerobic.
Pouring it
- The donut ring. Pour root drench in a ring an inch or two in from the pot’s rim, not against the stem. The feeder roots are at the edge; a wet stem base invites rot.
- Foliar spray at dawn or dusk, both sides of the leaves, strained so it does not clog the sprayer.
- Mycorrhizal fungi go in at the watering can, never into the 24-hour brew, where the spores drown.
- Skip the fungi for brassicas. Cabbage, kale, rutabaga and radish do not form mycorrhizal partnerships.
- No blood meal on anything flowering or fruiting. Nitrogen at bloom gives leaves instead of fruit. Never indoors, either: it smells and draws gnats.
- Seedlings get it weak and in the morning, about one part tea to three or four of water, a few tablespoons around the root collar.
Dry amendments
The teas pair well with small top-dressings scratched into the soil: kelp meal for trace minerals (all crops), bone meal for flowers and fruit, a little blood meal for leafy heavy feeders. The microbes in the next drench digest them faster than rain alone would.
What to watch
The plants tell you. Deep green and steady growth is good. Pale new leaves on a heavy feeder want nitrogen; pale leaves on a pumpkin vine may just be the variety. Write down what you poured and when; the pattern only shows over a season.
