Lots of rain. Make shift shelter is doing its job. Not much growth since topping. Did some low stress training because the stem is pretty thin. Hoping this will help so the wind won't break her.
Dude, add more soil, mulch and shit around it (without necessarily like heaping soil against the stem), give it a bit extra sugars/carbs, calcium, phosphorus, vitamin E.
No jokes, it keeps the roots quite a bit warmer (like even just for water retention, other than extra insulation, which might seem counterintuitive, but aids thermal regulation), phosphorus and sugar for heat/internal energy. Calcium to "buffer" things and aid phosphorus and other uptake. Vitamin E for cold resistance.
I've grown several hundred plants through winter, sometimes as cold as -6c (still warmer than some other places).
Cheers, and good luck. I'm currently doing winter grow (germinated seeds at worst time possible, start of winter).
