Rainlilies & Stagonospora

Like Peter and Mark, I always added leafmold (UK 
leafmould) to my bulb potting soil when I grew 
bulbs in plunged pots in coldframes. I harvested 
this component by sieving the top layer of soil 
under an area of alder trees on my former 
property. Every day during repotting season I 
harvested a large wheelbarrow full to mix into 
the day's batch of soil. It was a hard job but 
worth it. One belief of mine, however, is that if 
you use "live" leafmold like this, it's important 
to keep the bulbs dry during their dormant 
season; otherwise the microorganisms that 
decompose the leaves may attack the bulb tunics. 
You will be able to see the mycorrhizae on the tunics.

Now I have plenty of oak leaves thanks to my 
neighbors and three large compost bins for them, 
but I don't have a shredder as I could not find a 
well-reviewed one that is electric rather than 
gas (petrol), and it is too hard to start the gas 
ones. Any advice on this would be welcome.

I don't know why I'm worrying about plants right 
now as most of them are probably going to die in 
the current week of record low temperatures here.
