Growing potatoes update

A reader has asked if potatoes can be grown in the plastic tubs that are sold by Bunnings, Big W, etc., and I will answer it here as the links may be helpful to other readers.
Yes, Rebecca, they would be suitable if you add plenty of drainage holes and put several centimetres of gravel in the base of the tubs so that the potting mix does not block the drainage holes.
Opaque tubs provide similar conditions to small or medium drums (in that the young plants will be more shaded) and you should use those instructions for the tubs in this post. Basically the seed potatoes need at least 15-20 cm of potting mix underneath them and 15 cm of mix above them. Seed potatoes should be sown/planted 30 cm apart and, if they are the tubs I’m thinking of, you would probably only get one plant per tub as there is not really enough room for tubers of 2 plants to form.
The how and why of ‘hilling-up’ potato plants can be found in this post: Growing potatoes.

Advice on suitable soil conditions for the best results from potatoes can be found in Potato beds.
