Dear All,

Last summer we had a patio built, along with a couple of planting
walls. Our cat has for the past year been religiously using a certain
area as her toilet. As she was previously a cat litter girl I don't
want to confuse her by stopping her going there.

As its now planting season I would like to plant in this area. For the
first time in a year I spent a lot of time a few weeks ago digging
around removing all toilet, along with fossilised toilet remains, from
the area. However, as my toddler has proven, there is still a lot
there.

I did plant one lone small lavender a few weeks ago and that appears to
be sprouting. I would ideallly like a lavender border, or anything else
colourful and scented. Ideas?

My question? Does anyone know of any plants/ shrubs/ climbers that
would survive in such an environment? If not, do you think digging in
loads of fertiliser/ compost/(?I am a new gardener) would solve the
problem adequately enough?

I would much appreciate your advice.
Many thanks

Rebecca
