I prefer the Trumps too Jo!What a beauty!
It makes sense that extremely fine-grained SiO2 (silica) would be effective against insects, as it apparently blocks their spiracles (suffocates them, essentially). This is the idea behind diatomaceous earth, which is largely just very fine-grained silica. I don't understand why it would be effective against viruses... ?
I don't think Gerard was making claims about its effectiveness against viruses Lori, more on bacterial and fungal diseases.
There is a form that you can use against insects and virus too, but i have not tried these yet!

I am going to fill some zipbags with 20 gr each from the different forms and this will cost 2,50 euro each.
We've had two days of beautiful sunshine and its brought on quite a few snowdrops. Trumps and David Baker are both fully out now, in pots. They have spent the winter in a sand plunge with no overhead protection.Side by side I definately prefer Trumps by miles. David Baker is showing the aberrant outers that Atkinsii gets.
I am thoroughly confused by Trumps / Trymlet /Trym and wish I could see them side by side.
...not as special as David Baker or Trumps but flowering early.
