I spent an hour or so today, in the garden, scrubbing my rose stems with a toothbrush. Neighbours and passer-by must have thought I was mad... But we had a bit of a scale infestation on a few bushes and I like to go with the gentle option first. So there I was, gently scrubbing at the stems with a soft-bristle brush, watching the scale fall to the ground. Then, when the stems were almost visible, I gave them a quick spray with the pest oil.
My new shoots are already peeping out. I do believe they'll be rather happy with their pristine new home!
