Hello I've just been chopping leaves this morning (reduction therapy)got 3 bags where as bagging un chopped would be 10 bags,use a wire mesh cage or bags if not a lot of leaves and a good rotary mower,try Sork mole treatment,it small Allium with yellow flowers can be mown off they absolutely stink I crushed a leaf and my eyes watered for half an hour,if the moles are in the garden start at the house and put a row in 4 yards apart between bulbs then another row a week later,if the moles are coming in from out side the garden put the Sork bulbs at 8 yards between bulbs called a cordon sanitare jezza
