This revolting slimy algae is forming on gravel/stone surfaces ~ pathways, carparks, cobbles. We think it's Nostoc. First (modest) appearance was in 2010; now it's widespread, sometimes in carpets up to 1.5cm thick (and counting).. Thrives on rain, even in this cold weather. Very unsightly, dangerously slippery underfoot. Can you suggest a chemical for control / elimination? (Drainage not an option) . (These Photos is from web; not my own.

The books all tell us that we should cut down the canes of autumn fruiting raspberries (mine are "Autumn Bliss") well into the winter and I'm wondering if it necessary to leave it so late? Do the plants need that lateness (like daffodils do in order to store food in the bulbs) or is it OK to cut the canes down once fruiting is finished?I would like to cut my canes now (October) but am reluctant to do so without knowing why the common practice seems to be to leave them for another 2-3 months.

l am in the process of building my base for my new green house 6 foot x 10 foot. l have read in a book that a good ldea is to put sheets of styrofoam around the outside frame of the greenhouse 2 foot deep to keep the cold soil coming into the soil in the greenhouse. Is this safe to do? can or would any chemicals leach from the styrofoam.

I have some comfrey/nettle tea left which I made in May. I'm wondering if it's okay to still feed some of my tired looking shrubs with it at this time of year, and if it is possibly too old after 5 months brewing?
