| Primroses are lovely spring blooming plants but can be difficult to grow. Some gardeners use them as a spring bedding plant rather than trying to grow them as perennials. Generally primroses prefer semi-shade and a moist soil with lots of organic matter added. They must not be allowed to dry out during the summer but they must also not be water-logged during the winter. They should be mulched both summer and winter. Slugs and snails are their worst pests, but spider mites can also be a serious problem during a hot, dry summer. Primroses grow over a wide range of climatic zones depending on variety. For an in-depth look at the various types you might refer to a specialty perennials book such as Perennials for American Gardens by R.R. Clausen and N.H. Ekstrom, ISBN 0-394-55740-9. |
