Planting Primrose can be a beautiful addition to your garden. Growing primrose plants from seeds is not difficult, as long as you understand that they need a moist medium to germinate and grow best in a shaded area (such as the north side of the house or protected from the sun by taller hedges).

Step 1 -  Germinating the Seeds

The seeds do best if planted in an equal mix of sand and peat moss and placed 1/16 to 1/8 of an inch deep.  Since this mix has no nutrients, it is best to put it over one inch of planting soil. Keep the soil very moist during the germinating process. The best environment is when the tray is kept in a cool area at a temperature less than 80 degrees (the cooler the better). Also, covering the tray with clear plastic sheets will help contain the moisture.

Ste p 2- Transplanting

Primroses plants do not transplant well and should only be transplanted as a seedling after they develop their second or third leave. Make sure you have a prepared area to move your seedlings. They will get better root growth if planted in deep flats rather than pots.
The smaller varieties of Primrose should be dispersed six to nine inches apart. For the larger and more aggressive varieties, plant the seedlings approximately forty inches between each seedling. An area that has filtered light or shade is best, and it needs good drainage.

Step 3- Soil and Fertilizing

The soil is best at an equal mixture of loam and peat. Apply a cup of any complete commercial fertilizer for every bushel of planting soil mixture. Build up this flower bed at least eight inches in depth. Primroses prefer cooler soil and are best with an inch of mulch over the dirt.

Step 4- Time of Year for Transplanting

It is best to plant your seedlings after the last frost in early spring. For late season planting, the most shaded and coolest areas of your garden work best. Once established, the perennials will grow well. Organic fertilizer applications regularly during the growing season will improve growth.

Step 5 -  Trimming and Separating

After the plant has bloomed and the flowers have wilted, trim the plant by cutting off the entire stem. This continued pruning will encourage a second blooming.

If the plant is getting too large or starting to die it is time to separate the plant. Separating the root ball will give the plant more room to grow and will help expand your garden. Gently dig up the plant, being careful not to damage the roots. Shake off any dirt and use the garden hose to wash away and loosen any remaining soil.

With a strong garden knife or hatchet, separate the root ball. It is best for each section to contain two to five shoots. Replant in the same depth as the parent root. Water the plant well to help each section reestablish its root system.
