Primroses need to be planted in a cool, somewhat shaded area that has rich, well-drained and slightly acidic soil. Primroses prefer soil that has a pH of 6.5; Indiana soil is naturally around 7.5. By adding small amounts of aluminum sulfate, the pH can be lowered to the desired level.
If the plant is happy with its environment, it will grow vigorously, needing to be divided every couple of years. The crown should be planted right at the soil level, and plants should be spaced about 6 inches apart. Water twice a week all summer and mulch to keep the roots cool. Put a thin covering of leaves over the plants for winter protection. Since the flower is often bothered by slugs and spider mites, keep slug bait handy.
I encourage you to drive past the corner of Shelbyville Road and Bancroft Street to view the beautiful garden.
When the power lines were being installed along Shelbyville Road, the redbud trees were removed, so Maryann and Norbert created a new way to welcome spring. They bought a few primroses at Rucker’s Greenhouse and fell in love with them, faithfully planting them for 35 to 40 years. Their son now tends to the garden and has added lilies of the valley, bleeding hearts and hostas while replanting redbuds.
I’m sure you will enjoy the scenery.
“In the spring at the end of the day, you should smell like dirt.”
