Potato Onion Resurrection

[Tim DH]

Hi A.Pel,
    There is a bit of info. on the web hinting at variations of the White Rot treatment. .. Try this for instance:

https://www.gardenfocused.co.uk/fruitarticles/pest-disease/white-rot-allium.php

     What you'll really struggle to find is info. about controlling Club Root (of brassicas) by a similar means. It's the same scenario, just use liquidised cabbage of some description, in stead of garlic.

I'm joining in on this thread as I've recently started a grow out project with potato onions with a aim of getting seed for our website.

On the subject of white rot, Ive had the spores in my soil for over 23years and what Ive found is as you improve the soil the number of infected plants go down. Summer just gone I had no plants onion plants showing signs of infections. Garlic - I go back 15 years ago where I was loosing 50% of my beds, nowadays its no more than 2%.

I have not had any luck getting my potato onions to produce seed. Has anyone here found a way to encourage this that does not involve starting from seed initially?

I planted about 100 of last years seeds from my potato onions this spring. Only two germinated. The ability to reproduce from seed has well and truely been bred out of them. That has to be put back in so I am crossing in other varieties this year to see what might come of it.

At least the two that did germinate look to be strong plants.
