Had a plant that nearly died from the frost and cold last year, so wish to
insulate from the cold and its to be kept on a small patio outside, but
adjacent to the house.

The patio consists of paving slabs (placed on a hardcore of broken bricks
base) about nine inches above the soil level.

I intend wrapping bubble wrap around the plant (a bamboo) and the pot.
Bearing in mind the ground soil (and maybe these slabs? )are sometimes
warmer than the air temperature, should i *insulate* the pot from the patio
slabs when i wrap in bubble wrap; or keep the pot placed next to the paving
slabs, and just place the bubble wrap over plant and pot.
