Hi Daffnetters

I’ve finished HWT my bulbs for this year and will soon begin planting now that the evenings are getting cooler and autumn flowers are appearing here in NZ. I have used up all my formalin now and wonder if there is another safer alternative to use in two years time when I dig once more? Ted Snazelle wrote an article on June 10, 2013 about using bleach and I wonder if this would prevent cross infections when I HWT. I usually treat about 800 bulbs over two days at the end of our summer here using a Vaccola outside and  it’s worked very well for me.Neither nematodes nor  Basal rot have been  problems in my small patch to date. Any practical ideas for a suburban grower like myself, would be appreciated. Thankyou.

PS. I’m looking forward to beginning to plant while following the finals of the World Cup cricket ( & NZ) on  radio – all part of my relaxing autumn routine!

    Margaret,

    As formalin has been banned for many years now I wouldn’t admit to still having some. It is very nasty when tipped into drains or the soil. I will be interested in the replies you receive as I am happy to believe that the HWT on its own is effective for most pathogens provided your bulbs have been sun dried first.
