Hope you have been giving that hoe a sturdy work out Stellamaris.
Have not used a hoe since we gave our allotment up some years ago (pressures of work) I too enjoy hand weeding, so long as the weather is kind! I have never heard of your American version snd don`t know what it looks like or what difference it makes.
Didn`t know you were looking for a copy of that rose book, there was a whole series of those "expert" books and I don`t know if they are still in print, all the garden centers in our area used to stock them, as well as that one we also have the "tree and shrub" one and the "vegetable and herb" one, the flower one disappeared so I feel we must have lent it to someone who "forgot" to return it! As Avalon says, they are very easy to understand and yet comprehensive, I will keep my eyes open and see if the G. centers still stock them as they are quite old now.
