Can you use a glass bowl as a cloche?

I don't want to buy a cloche, can I use glass bowls and vases as substitutes?

    I don't see why not - so long as they're frost proof. I'd be very careful about using vases but Pyrex bowls or similar should be OK

  • How will you ventilate them?  There has to be air-flow otherwise moulds like botrytis will develop on your plants.

    You could prop them up on wedges of wood or brick offcuts so some air gets in. If it’s to protect something tender like dahlia tubers that don’t need light over winter, upside down old colanders, hanging baskets, those plastic mesh baskets garden centres used to support potted plants, old pots or shaped chicken wire can be stuffed with straw for cheap winter protection. If they need light forego the straw and just wrap clingfilm over the top of some sort of mesh structure.

    Ah ok, so you really should get a proper glass cloche? How is it that they are ventilated?

    They have openings in the top, or along the sides.

    Ah, I see. Any recommendations for cheap cloches anyone? 
  • What plants do you need them for?

    This is a good company, although I've never bought cloches from them. It'll give you an idea of the various types etc.
    As @Dovefromabove says - it may depend on what plants you need them for.  :)
