Preferred method of planting

gardenman91

Hi everyone, I’m curious as to what people think is the preferred method of planting for chalky soil with elements of clay. Would you:
improve the soil and then plant
OR
plant and then mulch the soil instead

Many thanks

I would choose plants that like chalk.

The specific plants are roses and penstemon. For roses could you improve on planting and mulch after, both with rotted manure or would it be too much?Fire said:
