How to Level a Sloped Flower Bed

Line the lower end of the flower bed with decorative stones or bricks to contain the new soil. Build this artificial retaining wall up until it reaches the same level as the high end of the garden. Line the inside of this wall with fine wire mesh for better soil retention.

Fill the low end of the garden according to your specific situation. If the low end sits 15 to 20 inches lower than the high end, use 10 inches of inexpensive fill dirt as a base. Rake the fill dirt to even it out and meet the slope of the flower bed.

Fill the remaining space with a more expensive and nutritious mixture of organic compost and bagged garden loam. This foundation gives the plants rich, crumbly and moisture-retentive soil for growing. The plants won't thrive in the fill dirt, and shouldn't grow in that base. Add soil mixture until you create a level planting surface.

Even out the garden's nutrition level for an equal growing experience. Dig into the top 5 inches of natural soil on the high side of the garden, and turn 2 to 3 inches of organic compost into it. This ensures healthy plant and flower growth on both sides of the garden.

Add 5-10-10 or 5-10-5 granular fertilizer, per manufacturer directions, for good starting nutrition throughout the garden. Water the soil to moisten it and dissolve the fertilizer before planting.
