Dig a trench 2 spades deep and reserve the soil in a wheelbarrow. Add at least 4 inches of compost to the first trench and mix in. Dig a second trench 2 spades deep directly behind the first, and deposit the soil in the first trench. Add compost to the second trench. Once you reach the end of your flowerbed, deposit the soil from the wheelbarrow in the last trench.

Single or simple digging, is similar to double digging. Instead of digging 2 spades deep, dig a trench 1 spade deep. Add a thick layer of compost and dig it in. Dig another trench behind the first, depositing the soil from the second trench into the first. Continue until your entire flowerbed is cultivated.
