Magic Grass

At a garden shop they’re selling Magic Grass, a patch of sod that doubles in size every day. A man goes to buy some and figures that his garden is big enough that if he buys one patch, it will cover his garden in 14 days, because each day it doubles in size. So he decides to speed up the process, and buys two patches of sods.

How many days will it now take for the Magic Grass to cover his garden?
