Living Soil Feeding Schedule

Living Soil · Feeding Schedule

Charge once, feed weekly, finish on water

One living soil from veg to harvest — top-dressed, never bottled, and tuned lean for flavour. Here is the whole rhythm.

The rhythm

01
The charge
Rock phosphate 12 g/L, or bone meal 9 g/L. Worked through the soil once, a week before planting.
02
Veg · wk 1–4
Veg blend 3.5-0.4-2.8, top-dressed weekly. Nitrogen-led, to build a strong frame.
03
Bloom · wk 5–10
Bloom 1.9-0.4-3.6, weekly. Nitrogen eases back, potash rises — lean nitrogen lifts flavour.
04
Finish · last 2–3 wk
Plain water only. Demand falls and nitrogen tapers into a clean ripening.

How much, per week

Weekly top-dress for a 30 L pot, by build. Scale up or down with your pot size — or use the calculator for an exact figure.

Build Veg / week Bloom / week Charge (once)
Flavour — leanest, best aroma 35 g 33 g 270 g bone / 360 g rock
Balanced — the default 42 g 40 g 270 g bone / 360 g rock
Max yield — most weight 49 g 43 g 270 g bone / 360 g rock + grow-N in mid-flower

1 tablespoon ≈ 15 g. Mix each dose with an equal part compost or worm castings, scatter on the surface and water in.

Fruiting & root veg · extra P and K

Tomatoes, potatoes and peppers are heavier phosphorus and potassium feeders than flowering plants. Add extra P — +5 g/L micronised rock phosphate, worked in, nitrogen-free — and extra K — sulphate of potash, about 0.5 g/L through flowering. The regular programme is tuned for flowering plants.

Getting it right

Top-dress
Mix each dose with an equal part compost or worm castings. Scatter on the surface and water in — never dig it under.
Soil pH
Aim 6.2 to 6.5 — it is what dissolves the charge. Above about 6.8 the phosphorus release stalls.
Base & fungi
Use a compost or worm-castings base. Add mycorrhizal fungi at planting — near-essential with rock phosphate.

Reusing your soil?

Blends at full strength, and only a third of the charge — last year's phosphorus is still banked. Top the organic matter back up with compost and you are away.
