Frost proofing plants & pots
Another simple question for you! (Sick of the sight of me yet?)
I have a small bay tree (i.e. under 50 cm in height) in a pot (raised off the gravel by feet) by my front door (sheltered both under the eaves and on two sides by wall) and an ever disappearing house moving date that means this tree (Aldi special so don't know much about it other than bay tree) will have to stay outside for the forseeable future and endure the weather.
I've heard that you can protect plants in pots by bubble wrapping them but I can't find an idiots guide explaining exactly what you need to do. Do I just wrap the bubble wrap around the pot or does it also need to go over the soil (which currently has slate on which I fear has little thermal properties!) Or even underneath the pot? Do I also put something over the plant (right now I'm considering making a bamboo stick frame and going crazy with some cellophane but can I get away with just tucking it up at night with a bubblewrap blanket?)
Thanks ever so much!
