Earth em up

I was sent this link www.henleypotatotower.co.uk/content/science it is a sales link but the experiment is interesting. It does make it clear how and where the potatoes form.

I earthed up the few that had just begun to show yesterday, we were forecast a frost last night.

The link gave me a better understanding of why to earth up potatoes, I will pay more attention to mine this year.

That's a very interesting link, some things there that I didn't realise

Mine are not showing yet.

Oh I always earth up with rice hull and coco coir right after they peek out of the top and I only let one shaw grow must be why I get small taters. I'll remember to let at a few more shaws develop rather than covering up most of them. ;D Hope I get a lot of big uns for more curly fries.

The coco coir we make it ourselves we just borrow the machine that turns the coconut husks into coir and fibers after we've processed our coconuts. The rice hulls we get for free from a rice mill in the area. We usually take the truck and haul away all the husks and chaff we want whenever we need to plant taters.

The potato leaves are not very high, am I supposed to cover them with soil or just enough so that some leaves show? I did this today, but perhaps I should have covered them.
