I have been told that wood ash from a small iron stove are so burnt out that they are useless for the garden. Is this so? At the moment I throw them onto the lawn, is this OK?

I bought a cutting of a fig last year at Glenarm Gardens and it is flourishing in its pot in the greenhouse. I have always wanted to grow a fig and ask whether it should be kept in a greenhouse or is it capable of living outside against a south facing wall. The wind does hit this wall! The fig is "brown turkey".

My tunnel is about 8 years old and firm and good but I have awful algy on the outside. I have tried washing up liquid and Domestos bleach but the green algae (and black on the top) remains. Jeyes is not to be used on it (so the tin says) . Can you please suggest something to wash the tunnel with? I use a window cleaning sponge on a long handle as my tunnel is tall and I cannot reach the top by hand

I have a huge heap of leaf compost from last years leaves. I used composter and it has worked a treat. The trouble is, when I used the previous years leaf mould on the garden, I got thousands of tree seedlings growing plus a few other weed seeds which had invaded my heap! Is there some chemical I can use on the heap to kill the seeds before I use the leaf mould in the garden? Would something like Roundup be suitable? I don't want to kill the plants in the garden!

We had a commercial chipper in to chip a large ash tree which had fallen down. How long until the chips can be used on the garden? A year? Two years? !! I have a huge pile.

I sent you a photo of the bougainvillea leaf but may have sent it to the wrong section. I have had my plant about 10 years and never know what type of compost to repot it in. I gave it some rhododendron feed and the result is yellow leaves with dark green veins. Also very few leaves. It is flowering profusely and is a wonderful sight at the moment. Would B@Q peat free compost be good or multi purpose with peat? Is it acid loving or alkaline? We grew them with either in Kenya I think.
