The use of primula (primrose) in landscaping offers versatility to rock gardens or shady spots. Primula grows best in USDA hardiness zones 5 through 10. It requires moist but well-drained soil with partial shade. Neutral to slightly alkaline soil brings out the most blooms on a plant. Early spring is the best time of year to add primula to the landscape.
Dig a hole that is several inches deeper and wider around the root ball of the primula plant.
Mix one part dirt, one part sand and one part peat together in a small bucket. Use the dirt from the previous step.
Tip the potting container onto its side and lightly tap the bottom to loosen the primula plant. Set the container aside after removing the plant.
Fill the hole with a few inches of the soil mixture from the previous step.
Place the primula plant into the hole. Backfill with the remaining soil mixture.
Water until the soil is very wet. Allow the water to absorb. Fill in any depressions with additional soil.
Place a 2-inch layer of coarse mulch, such as pine bark nuggets, around the base of the primula plant.
