Gardeners are full of bottle

We have been recycling all our plastic bottles in the garden. We cut them into three sections: we use the bottom as pots for cuttings (my husband is then happy to give them away, rather than his coveted pots!), the middle section protects plants from slugs, and the top part is popped on canes to protect our eyes. We use plastic milk bottles too, for growing salads, leaving the handle so we can hang them up. Can other readers offer more recycling ideas? Sue Baker, Balsall Common
