Luckily, you can move plants around. Prepare the soil. Sprinkle the compost and any other amendments over the surface, along with half the fertilizer. In addition to mixing, you are loosening the soil. Plants like fluffy soil, the tiny air pockets provide oxygen that soil bacteria need.
Roots grow well past the drip line of a plant's leaf body, if the soil is good and loose.
You're ready to plant. Before you do, watch a garden buddy planting.
