Most lilies will benefit from having a ground cover that will shade the roots and protect young shoots that emerge in spring, however avoid planting with strong perennials that may smother or crowd them out.

Planting is best done in early fall or spring and should be planted 3 times the height of the bulb in depth. For instance, if the bulb is 2” high, plant it 6” deep. Make sure to provide them with a light loamy soil with lots of organic matter, and ensure excellent drainage. Lilies are not exceptionally drought tolerant, so water thoroughly during very dry periods. After flowering, reduce water and allow them time to dry before going dormant. Unless you have very large clumps that require dividing, try not to move lilies once they have been planted and established.

Moles and mice may be a significant problem during the first year after they are planted, it helps to coat the bulbs in sulfur or copper oxide before planting. Lily leaf beetles are rampant in the Ottawa area and propose a real threat to your prize beauties. The best way to control their populations is to check constantly on the underside of the leaves for bright orange eggs and wipe them off. Hand pick off larger beetle adults and squish them. It’s not a pretty job, but they are tenacious and will make a full meal of the leaves on your lilies if you don’t destroy them.

Some of the most fragrant lilies include those of the Oriental and Asiatic hybrids. Although they are often sold as seasonal house plants or cut flowers, you can easily bring an exotic feel to your garden by planting a few clumps in well drained sites.
