Hi Anita, Robbie on Twitter says "fungus clear, fungus fighter, rose clear or pick off & dispose of effected foliage."
And Mark adds "if the rose is very bushy with foliage, try removing some foliage to increase more air into and around the bush and spray" "fungus fighter is the best as its systemic - any new growth should be mildew free"

Hi, Shirley, I think it is important to find out what the white bits were. A pest? Make sure all fallen/dead leaves are raked up and destroyed as they might harbour whatever pest or disease it has/had. Is it completely devoid of leaves? Kathy C
We have just moved to a newly built house, have put a border to grow flowers. We planted Lonicera Halls Prolific which started off very well. Then we noticed bits of whit on the leafs and leafs falling off. Is it wise to cut it back and start again.

Hi...Some of the leaves on my apple tree are curling up and they are covered in a pale grey powdery white/grey substance that can be wiped off - it also seem to have affected the amount of apples I have this year - although I dont remember there being an awful lot of blossom on it this spring - unlike my peach tree...Any suggestions...Thanks

I had the same problem with mine this year (an many others). I managed to prevent further leaves from mildew by spraying the leaves on both sides with a mix of water and 20% skimmed milk (full fat not good for plant). Apparently it should be done weekly to keep mildew at bay. I only did it once but was put of by the milky smell and the fact that it left a very slight white stain on each leaf (though not as bad as the mildew itself).
Despite only applying once it did seem to stop the spread and a week of windy weather and watering at the base probably helped get things back on track. In future I will try the less smelly version which uses a teaspoon of Bicarbonate of Soda in about a litre of water sprayed on.
Hi, I have a small hedge of amalanchier. They have plenty of space around them and they have been watered regularly. All the planst have been infected with powdery mildew. What is the best course of action to take?
Thanks
