I'm not sure it's possible to change the contents of gardening magazines. There is only so much that can be written about a given aspect , we are interested in a 'hobby ' that has several areas of speciality, propagation, lawn care , seed saving are just some of the areas of interest.
We do read one of the magazines on a regular basis and we enjoy it, in the armchair with cuppa or something a little stronger
. We also refer back to previous issues on occasion when the grey matter needs a nudge.
