Preparing a New Flower Bed in Heavy Clay: A Step-by-Step Guide

Late Winter Method

1. Dig when soil is damp; turn large clods over to kill grass/weeds.
2. Let clods dry a few days, then break apart.
3. Till (or hand-turn) to pulverize.
4. Remove a wheelbarrow of soil; add 2 cu ft bag of soil conditioner per 8 sq ft.
5. Add ½ cup 0-46-0 (superphosphate) and 4 cups garden lime.
6. Till everything together; return reserved soil and mix.

Result: 10-inch deep, well-drained bed. Redo every 3 years as organic matter decomposes. For longer life, add expanded shale (PermaTill) with organic matter.

the porous stones of expanded slate promote drainage and hold moisture
