Trachycarpus palm — Mg + K + micro foliar (vegetative, alkaline-soil compensation)
Zone: Trachycarpus palm — windmill palm (in ground) · Stage: vegetative
Provide Mg + K (via Quadro-K) + trace boost + uptake biology. K addresses lab deficiency directly. Same recipe used for soil drench at higher Quadro-K rate for ongoing K + S supply.
Products (8)
| # | Product | mL/L | Role |
|---|---|---|---|
| 1 | Base-Line | 2.0 | fulvic gel — chelator + mild acidifier |
| 2 | Topraq-Mg | 3.0 | Mg — chlorophyll, supports K function |
| 3 | Topraq-Micro | 1.5 | Multi-micro preventive (Zn just-OK in lab) |
| 4 | Quadro-K (Doktor Tarsa, DRT) | 2.0 | K — 610 ppm K in tank; addresses lab K 53 ppm; thiosulfate also slowly acidifies soil over time |
| 5 | Topraq-B | 0.6 | B — supports K transport + cell wall (low dose ~12 drops/L) |
| 6 | Fast-Line | 1.5 | Carboxylic acid — uptake + drops tank pH (essential for alkaline soil) |
| 7 | Alga-Line | 2.0 | Chlorella biostimulant |
| 8 | Bacto-Line | 1.5 | Bacillus shield — LAST in tank, apply within 4h |
Intentionally excluded
KCl — DO NOT — soil Na 379 ppm dangerous. KCl adds Cl to a salinity problem.MKP — DO NOT — soil P 168 lbs/A EXTREME. MKP would worsen P excess.topraq-ca — Sulfates + thiosulfate (Quadro-K) in tank — Ca would precipitate. Plus soil already at Ca 583 + Na 379, Ca foliar wouldn't help.topraq-co — Specialty use, not indicated.topraq-cu — Cu adequate per lab (0.83 ppm); kills Bacto-Line.topraq-fe — Fe adequate per lab (85 ppm).topraq-mn — Mn adequate per lab (8.4).topraq-mo — Specialty use, not indicated.topraq-zn — Zn just-OK per lab (0.86); Topraq-Micro covers.Total ~14.1 mL/L (~1.4% v/v). 10 L backpack uses: 20 mL Quadro-K + 30 mL Mg + 15 mL Micro + 6 mL B + 15 mL Fast-Line + 20 mL Alga + 15 mL Bacto + 20 mL Base-Line = 141 mL total products. Apply morning, frond canopy + underside priority. Replaces the earlier Mg-micro-only recipe — now addresses the root-cause K deficiency too.
